Wheel adapters

Post by Dennis_Brown » Thu Jan 16, 2020 10:31 pm

Can aluminum be used to make adapters. I have some aluminum slugs that are 8 inches in diameter and 5 inches thick.. If I make adapters out of them, how thick should they be?

5 inch thick should do it just fine... you may want to start advertising for some wide track fenders to go with em tho... 😉

most of the adapters/spacers used on 4x4's are made from aluminium (I'm in Scotland thats how we spell it :D ) im sure it would be fine for a model T

Typically Dennis the commonly available adapters are a minimum 1" thick. But consider the fact they use a standard lug nut that has to be recessed to just below the surface.

You didn't say what exactly your doing, but even if you could thin it down some more, I don't think I's go no less than 3/4" thick. Typically you want the fastener to be at least as deep into the material as its diameter. Example, A 1/2" screw should have a 1/2" of thread engagement minimum.

But you need at least 3/4" on a wood wheel hub to a wire wheel for clearance. Just Sayin', been there.

Not to rain on the parade, but if you are going to mount Model A wheels, to get at least two points of support you should use these;
https://www.speedwaymotors.com/Speedway ... UeEALw_wcB
The stud holes for the Model A wheel were never meant to be used as a contact spot only to keep the wheel centered and on the car. In fact, a properly mounted A wheel, the area under the stud holes would not even come in contact or would have very little contact with the A brake drum.
The Model T wire wheel was a little different. The outer diameter of the hub was part of the support of the inside of the wheels hub area.
I know the voices aren't real but damn they have some good ideas! :shock:

Every one is correct here, so keep in mind the thicker they are the more strain you willl put on the bearings & axle. Happy machining.
