Realizing how much dirt and crud was still stuck to the back of the trim; everything was scrubbed down with SOS earlier today. This allowed a better view to remove dents and made everything easier to handle. I was going to start with the worst dent first, but decided working in the reverse order might help develop better techniques as I went along.

The upper driver side piece was inspected again and requires only sanding and polishing. It really is in mint condition. As indicated in the next to the last photo above, the upper passenger side has problems which turn out to be so extensive it may cancel the project if I can’t successfully correct them.

It appears at some point in history this trim was indifferently installed off center and then beaten into submission to fit. The upper passenger side corner is so deformed the profile was changed from a flat surface to almost a half round. This both narrowed the trim and turned it in the wrong direction. It also reversed the banking from angled toward the windshield, to angled away from the windshield.

In an effort to unroll the curl, a simple jig was assembled and clamped in the vise.

I didn’t think to take a photo before straightening, but here are a couple of shots after about an hour of bending the trim back open and flattening the crown:

http://img802.imageshack.us/img802/343/jig02.jpg

http://img809.imageshack.us/img809/2696/jig03.jpg

I did manage to flatten the trim to nearly its original ½” width. Unfortunately off the truck and free to take its natural shape, the piece won’t presently fit a gasket. On the right is the compatible driver side part, the damaged passenger side on the left. In the last two photos the bottom of both parts are resting on the same platform.

http://img41.imageshack.us/img41/1495/match01.jpg

Not only do the ends not match up, the banking is wrong as well. It’s hard to show in a photograph, but the part on the right angles between 5-15 degrees towards the glass. The part on the left banks away from the glass about 5 degrees. Reversing the tilt hasn’t proven all that easy. These photos were taken after about 2 and half hours of bending and twisting. I not only need to reverse the angle of the face, but after that’s done I have to shrink the attachment blade/hook back into alignment, which I’m not sure is possible.

http://img17.imageshack.us/img17/1655/match03.jpg

All focus will be on this part until corrected or ruined, since there isn’t any point in restoring the other pieces if I don’t have a complete set.

More to follow.

Re: Markeb01 Build Thread
 
Last night and this morning I was about ready to abandon the windshield trim project. I kept picking up and studying the trim, but couldn’t visualize a solution. Later this afternoon I decided to give it another try and after another 2 hours at the bench the damaged passenger side trim is nearly an identical match for the driver side piece:

http://img805.imageshack.us/img805/2262/matched01.jpg

The biggest problem was the corner angled away from the glass, and the bottom of the trim pointed towards the back of the door. Pulling the trim around to fit the gasket caused the trim to roll over even farther, showing only the bottom edge of the trim instead of the face.

Having nothing to lose, I decided to flatten the face of the trim even farther (which it still needed), and simultaneously bend the trim in the required direction. I changed the metal pieces of the jig to fit even tighter to the oak board (along with a smoother tip touching the trim). This created a wedge fit that still allowed linear trim movement.

http://img545.imageshack.us/img545/343/jig02.jpg

From there I latched the trim under the jig, pressed down on the opposite edge with maximum force, and started massaging the trim with gentle hammer blows from a lightweight body hammer. Two hours and about 7 million hammer blows later (okay maybe not that many), the entire surface of the trim was nearly restored to the correct flat profile, and in the process of hammering and bending the face of the trim was now correctly angled toward the glass.

http://img827.imageshack.us/img827/1899/workingbj.jpg

The only remaining issue was the overall curvature. The end of the trim still pointed too far to the rear. Again the trim was latched under the jig and bent using maximum hand pressure in small stages. I kept comparing the two sides and marking where it didn’t match with a felt marker. Make an adjustment, wipe off the marks with lacquer thinner, compare again, mark again followed by more bending, over an over until the two pieces matched.

I also discovered a side benefit in the process. I inadvertently removed one of the small dents by squashing it flat in the jig. I wasn’t quite sure how I was going to attack some of the dents because they are right up against the J hook flange. Having this new knowledge, I’m going to cut a new metal jig plate that comes to a point, and has a rounded tip on the end. I may pad this with a small piece of plastic or leather and attempt to work some of the dents out with the jig where they cannot be reached with wooden tools.

I’m actually enthusiastic now to get this piece sanded and polished to see how good the repairs look, but I’ll probably hold off until the dents are removed from the last two pieces so I can do all the sanding and all the polishing at the same time.

So far so good. We’ll see what tomorrow brings.

I have two extra top pieces for the 60-63 if you get stalemated on the piece your working on. I have a top left and right side. I ran into the same problem with my trim. Was able to put a nice set together and about 5 hours of work to fix the rock dents, etc...

markeb01 05-04-2012 03:40 PM

Re: Markeb01 Build Thread
 
Thanks for the feedback and the kind offer. A couple of days ago I was thinking a replacement piece was going to be the only solution. Things are looking much better at this point. Judging by how long it’s taken so far I figure I have at least another 5 hours to go as well, just removing dents before the polishing can start. No idea how long the polishing will take, but it should go easier with new compounds and buffing wheels.

Next step will be sanding and polishing the upper right trim. I want to confirm it looks corrected under a fully polished shine before moving on to dent repairs in the lower pieces.

So far I’m reasonably impressed with the results, being this is the first stainless trim I’ve ever attempted to repair. I never needed to repair any previously. Years ago I simply selected pieces that were in perfect condition, because everything was readily available and relatively inexpensive. I kick myself now :banghead: for specifically not wanting the trim back in the 1990’s when mint examples were common in the local wrecking yards. At the time I preferred the simplicity of the black gasket, and obviously lacked future vision.

My wife and I searched through what seemed like and endless supply (hundreds) of 1960-66 trucks in local yards at the time, and I only bought what I needed. Back then they were whole trucks, not stripped carcasses. Believing this bounty would last forever, left behind were dozens of Chevy deluxe instrument clusters, floor shift and automatic steering columns, floor pans, door panels, original radios, deluxe switches and knobs, etc. None of it was particularly interesting or worth investing in to haul home at the moment. :whine: If only!

I’ll probably wait until next week before working on the trim again. It’s currently cold and damp, but next week is supposed to bring sunlight and 70 degree temps, which I’m really looking forward to.

Hey, where are you putting this trim???
My 66, 63 and both 63 Chevy's don't have 1 inch of chrome trim that even resembles those pieces I see in your photos.
What gives???

markeb01 05-04-2012 07:04 PM

Re: Markeb01 Build Thread
 
Thanks for the comments guys. If all goes well it will eventually look like this. The J flange on the backside hooks into a slot in the deluxe windshield gasket, as shown in the detail diagram below. This is the skinny trim, about 1/2" wide. The piece I’ve been trying to repair is the passenger side upper. It fits from the center of the windshield to half way down the passenger side. There are 4 small caps which cover the joints in the center and on the sides:

http://img18.imageshack.us/img18/8807/002svy.jpg

And this is the fat trim (used on 60's and 61's I believe) which almost covers the gasket surface. I prefer the broader trim, but it is even more rare and harder to find, so the skinny type will have to do:

http://img829.imageshack.us/img829/3559/003dnn.jpg

http://img837.imageshack.us/img837/4...dshield005.jpg

What I really like about the trim is that it visually shortens the windshield, especially on a flat black truck. Here’s a comparison photo from the Spokane Goodguys show last year. The black gasket makes the windshield look like the glass goes half way up into the roof. Comparing this photo with the first picture really demonstrates what the trim can do to change the appearance:

Re: Markeb01 Build Thread
 
Finally saw some sunshine this evening, which inspired another 3 hour windshield trim repair session. This time I was focusing on dent removal. The first step was figuring a way to hold the trim in position. With the vertical windshield post portion nearby on the right side, I simply added some screws to the jig board and strapped the trim down with mini-bungee cords:

http://img209.imageshack.us/img209/7...rappeddown.jpg

This was the dent I was after. I can’t figure out which of the before pictures shows this dent, so I may have missed taking one of it. The first tool/punch I started with was a length of styrene plastic, but it failed to transfer enough energy to the trim to effectively move the metal.

http://img801.imageshack.us/img801/7...oseupdentl.jpg

I switched to what used to be called “orange sticks”, designed for ladies fingernail maintenance. Both ends were used depending on the repair needed. Once the ends get smashed I trim them with fingernail clippers or grind a different shape on the Dremel sander. I also used the awl once to remove the very bottom of the dent once it was no bigger than a pit. This was done by hand without a hammer, because the risk of damage to the trim is so great.

http://img339.imageshack.us/img339/6360/03tools.jpg

Not realizing I didn’t have a before picture, this is the first shot I took about half way through the repair. The dent was quite deep and took over an hour to get to this point. I’m sure trim repair experts can go a lot faster, but this is my first attempt so I’m taking my time. If I have it all done and installed by August I’ll be happy.

http://img152.imageshack.us/img152/6695/04halfway.jpg

And this is the end result. I’m very anxious to start polishing these parts, but it is such a messy process I’m managing to hold off until I have everything ready to do at the same time.

http://img11.imageshack.us/img11/173...tdentfixed.jpg

Moving on to the second dent placed the elbow in the trim precariously unsupported, so a makeshift tower was put in place to keep it from flopping around.

http://img215.imageshack.us/img215/2149/06dent2.jpg

This was the dent I was after:

http://img109.imageshack.us/img109/5535/07dent2r.jpg

This one was much harder to work on, due to the design of the trim. I’ve rotated the photos so they are all oriented the same, but this dent is actually on the bottom half of the trim as installed on the truck. The difficulty being the half of the trim closest to the glass is single wall thickness. Dents can be accessed from the backside. Dents on the outboard edge of the trim are double wall thickness, the metal begin folded over to create the j hook flange. This prevents direct access to the dent. I went ahead and deformed the back edge in order to push the dent out in the front. Depending on where the dents are, it might be easier to drill a hole in the backside to reach the dent, but this could easily result in damaging the back side of the face with the drill bit. Care must also be taken to avoid flattening the edge of the trim, which will show when installed.

http://img213.imageshack.us/img213/7178/09backside.jpg

Again, this is about half way through the repair:

http://img600.imageshack.us/img600/8178/08halfdone.jpg

And this is a very poor photo of the semi-completed repair. I'll replace this photo with a better example next time I'm working on it. Almost all of the dent is gone, but a small “pit” remains. I was burned out by this point, so I’ll start again on this defect next time.

Re: Markeb01 Build Thread
 
Well I’ve decided to abandon the skinny windshield trim project. I prefer the beefier looking trim from the 60-61 trucks, and the larger trim would be much easier to repair having more open space on the back side. So I’m going to shut down until I find a good set of wide trim, or learn to find happiness with the black rubber gasket.

For me, the thin trim just isn’t enough of an improvement to warrant the work required or the risks involved with changing the windshield. Before I quit however I wanted to see how the first dent I removed looked after being polished. I sanded it with 600 grit wet, followed by 800, 1000, and 1500.

Moving to the buffer the surface was cut with Harbor Freight green cutting compound on a spiral wheel. A second pass with grey polishing compound on a loose cotton buff, was followed by white compound on a loose flannel buff. Here are the results.

The light reflection across the top of this first shot is from a twin tube fluorescent shop light directly above the trim. The white stripe on the right side is another shop light. The round light between them is a bare ceiling bulb. The dull area on the left is unpolished:

http://img24.imageshack.us/img24/1530/001xvy.jpg

This shot again shows the unpolished area on the left, and the finished/polished repair right in the center of the photo:

http://img535.imageshack.us/img535/5024/002niu.jpg

This is probably the best reflection I could capture. It’s pretty hard to photograph a shine, but the comparison between the unpolished and shiny portions are readily apparent. The first light reflection near the center is looking down the length of the shop light over the clean bench on the far side of the garage, and the two lights on the right side are two ceiling lights. The dark reflection under the center light bulb is the upper cab of my truck. The image is distorted due to curvature of the surface, but it does indicate the level of shiny reflection:

http://img444.imageshack.us/img444/1769/003ad.jpg

I’m glad I at least polished up the biggest repair because it does convince me the process works well and can produce show quality results with enough enthusiasm.

One final note – Harbor Freight polishing compounds seem to do a decent job, but the same cannot always be said for their buffing wheels. The spiral wheel and the cotton buff were badly out of round. Only a small portion of the facing surface ever touched the part I was polishing. The flannel buff turned out to be concentric with the hub hole and worked rather well, but the other two caused such tremendous vibration I had to keep my foot on the stand to keep the buffer in one place. And it weighs about 100 pounds and is sitting on top of a rubber floor pad.

Previously I had been using my son’s commercial quality buffing wheels and the performance difference is like night and day. Here are the worst two wheels after less than 5 minutes of use. They are so non-concentric almost 3/4 of the face remains untouched, and the loose wheel on the left is already coming apart from centrifugal force. These are rated for 3600 rpms. The data plate on the buffer I’m using indicates an operating speed of 3450, and a statement “use with wheels rated at 3600 rpm”:

That looks like a great job Mark. I have been following closely and appreciate you sharing your techniques. I will be attempting to repair an aluminum grill in the future and this info will help a lot. Of course I know that the aluminum is much softer and will be worked a little differently but the general technique will be similar.

Re: Markeb01 Build Thread
 
Big time project today. My right parking light rim had a good sized rock dent in it (arrow) and the upper screw has been missing for over a year. It looked like the speed nut was missing on the hood, but it was there and in good shape. I pressed out most of the dent from the back against a rubber sanding block and reinstalled it, adding a new stainless screw. Took all of five minutes, and will do until I can paint the spare set of bezels. It’s not perfect but I know I’ll sleep better tonight having done something important on the truck! :lol:

Re: Markeb01 Build Thread
 
To make a long story short, I have missing spinal discs and over the years I have reduced the rear coil spring capacity from 1500 pounds (stock), to 400 lbs (custom), to 150-200 pounds (Skyjacker brand) Jeep 2.5” lifting springs. With the bed cover off and the bed absent of any contents including a spare tire, the Jeep springs provided a comfortable ride, although they made cornering somewhat soggy. Since I put the Gaylord bed cover back on, the Jeep springs provide almost no load capacity, so I’m going back to the 400 lb capacity custom springs. My son is going to come over next Friday and pop them in for me, so I wanted to make sure they were presentable.

Today they were plopped on the bench and stripped using a 3.5” angle grinder and a severely coarse wire cup. A couple of good cleanings finished up with wax and grease remover, and they were ready for paint.

I preheated the springs under the lamps and painted them one at a time on a turntable with a swivel mount holding them from above. An entire can of high quality enamel was used to cover all the surfaces inside and out on both springs, turning each spring over once in the process. I wish the rest of the chassis looked this nice.

http://img593.imageshack.us/img593/1...1postphoto.jpg

Just one more thing accomplished on the checklist. Tomorrow the new gas pedal trim is due to arrive from ChevyDuty, replacing the poor quality substitute received from LMC.

Why don't you convert to rear air springs??? Two schrader valves and line and the bags with brackets are all you need...

markeb01 05-10-2012 08:49 PM

Re: Markeb01 Build Thread
 
I seriously thought about that for about a year before opting for custom springs instead. Two things bothered me. 1. I didn’t know if I'd have any problems in the sub zero temperatures we experience during extremely cold winters where I live. 2. At the time I was checking into kits and components it seemed that virtually everything on the market was sized for a lowered truck, and I wanted the ride height to remain unchanged.

I subsequently bought the custom fabricated springs while I was still working, and they cost a small fortune. Now I'm pretty much committed to keeping them because they work perfectly with the bed cover installed, and I've got too much invested in them to try anything different.

Thank you for the compliments guys. I’ve tried to accurately share things a person might find interesting or possibly helpful. And I’ll admit to a hidden agenda - establishing this stuff online so that in the future a descendent or two may enjoy discovering this segment of our family history, when I may not be available to provide details.

It’s interesting looking back, model cars in my youth were directly responsible for teaching me patience. Multiple failures quickly taught me to slow down and take my time. Being basically bull headed in the first place combined with four years in the Marines taught me determination. The consequences of not fulfilling a task were always bad, inspiring a zealous enthusiasm for seeing things through that has never diminished.

I really do appreciate the feedback. Thanks again.

Backing up a few days to post #126, I reordered new gas pedal trim from Chevy Duty and it arrived yesterday. I thought I’d take the opportunity to take some better comparison photos of the difference between the unbranded LMC part and the Counterpart branded Chevy Duty item.

The first improvement being the part was shipped in a box instead of a padded envelope, so it arrived in perfect condition:

http://img198.imageshack.us/img198/190/001hou.jpg

Interestingly they slap their own sticker over the original which lists all the different pedals the trim fits, but it peels back somewhat to reveal the details below. For anyone interested, this trim (and presumably the identical pedal) fits the following applications:
71-72 Chevy/GMC (deluxe)
68-72 Chevelle/El Camino
67-81 Camaro
68-72 Nova

http://img189.imageshack.us/img189/3920/002fsa.jpg

I understand many have been disappointed with Counterpart quality, but the three piece pedal trim they produce has all been top notch.

Here’s a comparison of the two pieces – LMC on the left, Chevy Duty on the right. I didn’t get them lined up very straight, but the differences are pretty obvious in a decent photo. On the LMC part the corners are too square, the center strip is too wide, the overall finish is poor with sharp edges on the front side, and worst of all the bottom and top of the insert openings are not parallel with the outside edges. A casual observer probably wouldn't notice anything was wrong, but it was the first thing I saw, and annoyed me every time I got in the truck.

http://img705.imageshack.us/img705/2172/003wco.jpg

Here’s the pedal with the LMC trim. It doesn’t look too bad, but the photo doesn’t show the lousy surface finish either:

http://img259.imageshack.us/img259/2977/004vhx.jpg

And finally here’s the assembled pedal with the Counterpart trim installed. To me this looks just like OEM and I’m very pleased with it:

looks great! I'm a bit of a perfectionist, so it would have annoyed me too that the LMC one was just "not right"...you should send the pictures to LMC to show them how it "should" be :chevy:
