Build Your Own Front Axle

I see a lot of homebuilt vehicles but something I haven't found was information on how to make your own front drop or straight axle.

I know its probably cheaper and safer to buy one that's already made. But for those who would like to build their own or how they are built for educational purposes would be ncie just to know in case one decides to give it a try.

Homebuilt Front Axles

So the front axle of a Model A or any hotrod for that matter are 3 separate pieces?. One straight piece and the King Pins are welded to the ends?

Correct. I used to make my own axles. 2" OD. 1/4" wall tubing. I used to heat and bend the drop portion. Cut the ends of the tube for upright. Then use 1 3/4" round steel bar stock for the spindle ends. Cut to length.

I made up a jig to mill/weld up the pieces at correct inclination and also set up in my Bridgeport to drill/ream for kingpin and lock bolt.

As stated the caster and camber specs are the hardest to get correct. Early Ford is different than early Chevy by several degrees

I was doing these axles because the ones I was previously buying from a manufacturer in Minnesota (MAS) were way off.. Side to side.

CCR T Bucket plans

CCR sells plans parts and raw materials to build T buckets. the plans have a couple pages on how to build a tube axle, They aslo sell the individual parts, tube and end boss, I built a couple of chassis but had 2 tube axles. I.ve had the plans and catalog for about 20 years, the price in the old catalog was about $ 100 for axle parts , A couple of local steel suppliers ordered the Dom tubing and had the frame rail material in stock for about half of the ccr prices. I found a hay wagon with a 46 Lincoln I beam axle and the good brakes for $ 25 and a trailer with a Ford I beam and Model A pickup box cheap so have shelved the Idea of building my own axles
