Anyone know what 5 on 4 1/2” drums can be fitted to 57-64 or 53-56 f100 spindles? Have a 62 f100 axle under my 56 Fairlane. Want to run 4 1/2” bp skinnys
Drilled the hubs and drums on my 53-56 brakes. Better check the hole in the wheels before you spend money. The hub is over size by at least an 1/8
Thanks for the reply’s. I drilled my hubs with an adapter as a guide. Bolts on to 5 1/2. Knocked studs out and transfer punched through holes for 4 1/2. It worked but not as accurate as I’d hoped. Seems ok with a conical seat lug nut but it’s not as forgiving with a shank style nut
Yeah, that’s not how it’s done. You need to clamp to a mill and index off the center, then bore each hole from precise measurements. Even the most perfect “adapter” is gonna give a few thousandths of wiggle when you stick a drill bit through it. If those bad holes all tolerance to opposite sides, you might never get a wheel on, let alone drive without the shakes. Rotate the hub and try it the right way.
This needs to be done in a machine shop, or by a qualified machinist, at least. I do this exact procedure a few times a month for customers. Any machine shop that remains open in this economy can do it too. They can also turn down the register on the hub to fit the wheel center hole, if that's an issue. There is no hope for accuracy without the proper tools and tooling. This is not even expensive.
Seems to me I bought a set of hubs years ago from a place called Thompson's Garage that were for early Ford that had a 4 1/2 ford pattern instead of 5 1/2. There was also a template that I saw on Ebay. Sort of a jig to redrill your bolt pattern.
