Re: My caster mod (with pictures)
When I had mine done, I took them to a friend's machine shop and we chucked them up in a lathe and used a flat bottom carbide end mill. A local machine shop would not charge you much to do this. A standard hardware store drill bit set isn't hard enough to drill the hardened cross shaft. Plus, using a mill is much more precise because you can lock the shaft in the mill and get the new pin locations located exactly.
