1947 Biederman Truck Fender repairs
Tonight in the shop we started the repair work on the front fenders for the 1947 Biederman Truck, seen here for reference:
http://i5.photobucket.com/albums/y16...ure%203604.jpg The fenders are made using 16 gauge steel, so this may be a bit challenging when we get to blocking and wheeling patches for the fenders themselves. In the meantime (while still waiting for the new English wheel) let's get started on the inner fenders. The driver's side is the worst, with so much rotted away that we couldn't get accurate dimensions. The passenger side was in much better condition, but just shy of 70 years has taken its toll in adding some wavy distortion. So we'll remake both sides for a better match. http://i5.photobucket.com/albums/y16...ure%203644.jpg In order to get a more crisp bend on the 16 gauge steel, we used a tipping die in the Lennox to thin the metal at the line of the bend. http://i5.photobucket.com/albums/y16...ure%204254.jpg http://i5.photobucket.com/albums/y16...ure%204261.jpg http://i5.photobucket.com/albums/y16...ure%204265.jpg Bending in the Baileigh Magnetic Brake.. http://i5.photobucket.com/albums/y16...ure%204258.jpg http://i5.photobucket.com/albums/y16...ure%204267.jpg http://i5.photobucket.com/albums/y16...ure%204268.jpg http://i5.photobucket.com/albums/y16...ure%204270.jpg This detail shot shows how the thinning helps get a tighter bend.. http://i5.photobucket.com/albums/y16...ure%204260.jpg Next, we needed a profile template for the rear radius, so the kick shrinker is used on a folded 19 gauge strip to add the radius.. http://i5.photobucket.com/albums/y16...ure%204279.jpg http://i5.photobucket.com/albums/y16...ure%204278.jpg A flat folded strip works better than an angle as if you shrink too far in this direction..... http://i5.photobucket.com/albums/y16...ure%204280.jpg ......you can simply shrink the back half to reverse the effect without the need for changing to the stretching die.. http://i5.photobucket.com/albums/y16...ure%204281.jpg Now with an accurate pattern, we can use the template on the new inner fender.. http://i5.photobucket.com/albums/y16...ure%204282.jpg http://i5.photobucket.com/albums/y16...ure%204286.jpg All trimmed... http://i5.photobucket.com/albums/y16...ure%204290.jpg http://i5.photobucket.com/albums/y16...ure%204291.jpg With the new clamped to the old, we can see what the years of abuse has done.. http://i5.photobucket.com/albums/y16...ure%204292.jpg One down, one to go.. |
Re: 1947 Biederman Truck Fender repairs
Today we got the second inner fender cut out, and took them both over for a test fit on the truck
http://i5.photobucket.com/albums/y16...ure%204303.jpg http://i5.photobucket.com/albums/y16...ure%204304.jpg The driver's side has a bolting plate in the middle of the frame for the steering box, so a relief notch was in order... http://i5.photobucket.com/albums/y16...ure%204306.jpg ....as well as a bit of trimming for some clearance so that the paint won't be chipped off on the first test drive. The fabrication of these parts are done, and we should pick up the new Tommasini Wheeling Machine this coming weekend so we can get started on the fender patches.. http://i5.photobucket.com/albums/y16...ure%204307.jpg http://i5.photobucket.com/albums/y16...ure%204308.jpg http://i5.photobucket.com/albums/y16...ure%204309.jpg |

Re: 1947 Biederman Truck Fender repairs
John's getting ready for engine start ceremonies, so I guess I need to get off my duff here. To help out in that regard, next we'll fabricate the battery tray which I don't believe came with the truck when John got it. Here's the best we have for a pattern:
http://i5.photobucket.com/albums/y16...ure%204646.jpg The hold down bracket for the prescribed Group 4 battery was with the truck, so we did some test fitting with the inner fender in place. It is a bit cramped for space, and John expressed concern of the availability of the Group 4 battery. Most local sources only carry the Group 1 in stock, which would also be a better fit.. So out with the old... http://i5.photobucket.com/albums/y16...ure%204644.jpg I did miss getting in the flat pictures, but here is the freshly folded and welded hold down bracket for the new battery size. http://i5.photobucket.com/albums/y16...ure%204639.jpg http://i5.photobucket.com/albums/y16...ure%204640.jpg All trimmed and prepped for paint.. http://i5.photobucket.com/albums/y16...ure%204641.jpg http://i5.photobucket.com/albums/y16...ure%204642.jpg Comparing the new to the old... http://i5.photobucket.com/albums/y16...ure%204645.jpg Next will be the new battery tray. |
Re: 1947 Biederman Truck Fender repairs
...and now for the battery tray, shown here cut to size and sides folded up...
http://i5.photobucket.com/albums/y16...ure%204650.jpg http://i5.photobucket.com/albums/y16...ure%204651.jpg For the end folds, the cut was started using a .035 cutoff wheel.. http://i5.photobucket.com/albums/y16...ure%204652.jpg ...and our trusty jig saw again... http://i5.photobucket.com/albums/y16...ure%204653.jpg http://i5.photobucket.com/albums/y16...ure%204654.jpg http://i5.photobucket.com/albums/y16...ure%204656.jpg http://i5.photobucket.com/albums/y16...ure%204658.jpg Both ends complete, and frame holes have been piloted. Once checked to the hole spacing on the frame they can be drilled out for the 3/8 bolts. http://i5.photobucket.com/albums/y16...ure%204659.jpg http://i5.photobucket.com/albums/y16...ure%204661.jpg |
Re: 1947 Biederman Truck Fender repairs
Always learn something when looking at your work.
I will put to use using the tipping die to help sharpen up the edge. Currently don't have a Lennox but when I grow up I will. Thanks |
Re: 1947 Biederman Truck Fender repairs
More progress on the Biederman fenders.. With Kyle on vacation I was shorthanded in the shop so John (the owner) came by and lent a hand.
First step was to remove the inner fender to see what we had to work with, added some 1/8 holes to use later for clecos in putting things back together.. http://i5.photobucket.com/albums/y16...ure%204723.jpg The front of the fender bolts to the bumper filler panel, and the rear bolts to the running board. These have a difference in height of 13-3/4, so some blocks were screwed together to hold the fender in correct placement while we worked. http://i5.photobucket.com/albums/y16...ure%204724.jpg The inner is getting replaced so the spot welds were ground out for removal. http://i5.photobucket.com/albums/y16...ure%204727.jpg Once removed, we found more pitting and damage than we originally thought was there, so now lets make this new as well.. http://i5.photobucket.com/albums/y16...ure%204728.jpg http://i5.photobucket.com/albums/y16...ure%204730.jpg New piece is cut out and the Wheeling machine with the go kart slick is used to add the correct radius.. http://i5.photobucket.com/albums/y16...ure%204732.jpg http://i5.photobucket.com/albums/y16...ure%204734.jpg Then the flange bend line is marked/thinned using a tipping die in the Lennox like we did for the inner panels we made.. http://i5.photobucket.com/albums/y16...ure%204253.jpg Then a tipping die and Skateboard wheel in the bead roller is used to make the initial fold on the marked line http://i5.photobucket.com/albums/y16...icture1081.jpg and finished up with a Step die so we could use it as a backstop http://i5.photobucket.com/albums/y16...Picture059.jpg The Erco 1447 with stretcher dies was used to stretch the flange in between tipping sessions. All done, matches the fender contour, we'll get the other side folded down next time.. http://i5.photobucket.com/albums/y16...ure%204736.jpg |

Re: 1947 Biederman Truck Fender repairs
Thanks guys!
Here's a quick video to show how the radius for the filler panel was done.. https://www.youtube.com/watch?v=ZnCTqLZg9lg With the flanges turned both directions.... http://i5.photobucket.com/albums/y16...ure%204737.jpg Looking at the rear of the fender that was adjacent to the cab, we found flat areas that seem to indicate some rubbing was occurring. So while we were fabricating the filler panel, we added about 1/8" to shove the fender outward away from the cab. http://i5.photobucket.com/albums/y16...ure%204738.jpg http://i5.photobucket.com/albums/y16...ure%204739.jpg http://i5.photobucket.com/albums/y16...ure%204740.jpg http://i5.photobucket.com/albums/y16...ure%204741.jpg http://i5.photobucket.com/albums/y16...ure%204742.jpg https://www.youtube.com/watch?v=4mZTMi3VMr4 |

Re: 1947 Biederman Truck Fender repairs
hats off great work i love metal work like that just dont have all those nice tools good job

Re: 1947 Biederman Truck Fender repairs
Thanks!
Time to break out the TIG welder. The new stumps for the upcoming metalshaping class work well as a welding table. The patch is securely clamped from inside to outside to get an accurate marking for tipping the fold around the wire. http://i5.photobucket.com/albums/y16...rman%20003.jpg Flexible Spline is used to carry the opening mark down the patch... http://i5.photobucket.com/albums/y16...rman%20002.jpg Tacked in with the TIG http://i5.photobucket.com/albums/y16...rman%20005.jpg http://i5.photobucket.com/albums/y16...rman%20004.jpg http://i5.photobucket.com/albums/y16...rman%20006.jpg http://i5.photobucket.com/albums/y16...rman%20008.jpg http://i5.photobucket.com/albums/y16...rman%20010.jpg http://i5.photobucket.com/albums/y16...rman%20012.jpg Next we'll wrap the wire and trim the front edge to size. |
Re: 1947 Biederman Truck Fender repairs
The shop is hosting another Peter Tommasini class this year, one of the items to pass out to the attendees will be some of the rare earth magnets that we use. I just got my delivery in yesterday, these are Cup-26 magnets from Applied Magnets, they have a 65 lb pull. We use them for holding paper patterns to wheel wells during test fit to copper strip for welding backer..
http://i5.photobucket.com/albums/y16...g/IMG_1760.jpg We install a csk 10-32 and lock nut to act as a handle, and they are ready to use... http://i5.photobucket.com/albums/y16...ure%203240.jpg http://i5.photobucket.com/albums/y16...ure%204863.jpg http://i5.photobucket.com/albums/y16...g/IMG_1761.jpg John has been assembling parts of the Biederman truck front end while waiting for the fender completion. He mocked up the hood the other day only to find out it didn't fit the cab as it should. http://i5.photobucket.com/albums/y16...n/IMG_1753.jpg It looks like the cab is wider than the hood, as the radius does not match and it's pushing the hood outward and up.... http://i5.photobucket.com/albums/y16...n/IMG_1747.jpg http://i5.photobucket.com/albums/y16...n/IMG_1748.jpg http://i5.photobucket.com/albums/y16...n/IMG_1755.jpg To explain, this is a 1947 truck that had extensive rust in the cab. He found a cab on a newer truck, 1951 IIRC, that was made by the same company. It now appears the newer replacement cab is slightly wider than the original, so our intended option is to cut a slice from back to almost the front and add a pie slice to push the radius out and the beltline down where it belongs. Looks like an easier option than remaking the hood. Something else to add to the list. Just to make sure the wider cab doesn't affect fender fitment, we also mocked up the lower hood side and clamped the tapered filler panels and took a comparison measurement from the outside edges, front and back. http://i5.photobucket.com/albums/y16...n/IMG_1756.jpg http://i5.photobucket.com/albums/y16...n/IMG_1757.jpg http://i5.photobucket.com/albums/y16...n/IMG_1758.jpg http://i5.photobucket.com/albums/y16...n/IMG_1759.jpg So we have just shy of 3/8 more in the back, or 3/16 pushed outward on each side. I think we can live with that, it likely is well within factory tolerance.. More to come.. |

Very nice work. How do you like Peter's wheel?

Re: 1947 Biederman Truck Fender repairs
Well, I need to make a little progress on a 16 gauge fender, so the highly precise stand for the Laser Level was used. We have about 13-3/4" difference in height from back edge of fender to front edge. So Laser is set at 13-3/4 above the table, with heights verified to all four corners of the table.
http://i5.photobucket.com/albums/y16...n/IMG_2327.jpg Prior to trimming the front of the fender we had measured some reference marks to the front edge for locating the new cut line.. http://i5.photobucket.com/albums/y16...ure%204760.jpg Adding those lower edge marks back on our fender patch, we adjusted the height of the fender front for the laser to match those marks by sliding our jack stand fixture around inside the fender until we had the correct height. Hey, this is technical stuff! http://i5.photobucket.com/albums/y16...n/IMG_2329.jpg http://i5.photobucket.com/albums/y16...n/IMG_2332.jpg And traced the laser mark with the sharpie... http://i5.photobucket.com/albums/y16...n/IMG_2334.jpg Initial cut to remove the bulk was done with the Milwaukee shear, the final was done with Midwest Shears. I figured slower = more precise... http://i5.photobucket.com/albums/y16...n/IMG_2337.jpg http://i5.photobucket.com/albums/y16...n/IMG_2338.jpg |
