What is welding your spider gears?

Welding your spiders up is just that. Taking the “spider” or side and pinion gears and welding them together in some shape or form.

Why should I do it?

The advantage of doing this is a cheap way to lock up your rear end. If the spider gears arent allowing both sides to rotate independently then both axles will turn at the same speed all the time. Thus giving you maximum traction to each wheel that you can possibly get.

How hard is it to do?

This all depends. You can either weld it up into a solid ball using more gears or weld the teeth together separately. The main thing you want to be aware of is how well the welds will hold up to the added strain of spinning both axle shafts at the same speed even around corners.

What parts do I need?

Parts needed is some cleaner to clean the gears of oil, a welder, and possibly a case of beer.

Can I do it to any gears?

anything is possible, but keeping it within reason is the main goal. Just dont weld your ring and pinion together on accident. You never know.

What are the draw backs?

The drawbacks are added stress on various components. You will eat tires a lot faster, parts are more liable to break, and wallets are more apt to becoming empty.

Why shouldn’t I do it?

there is better methods, but it still works.

Why is it called a Lincoln Locker?

I’m assuming some guy one random day busted out his Lincoln MIG welder, decided to weld em up and call it a Lincoln Locker.

What are the advantages or disadvantages compared to a traditional locker or spool?

Advantages: Cheap, easy, quick

Disadvantages: Weaker, unwanted drivetrain stress

Rear Bumper with Tire Carrier

GARD Pro Not Registered

By: cbbr

My rear bumper is 2×4 and 2×2 3/16 with 10 guage sheet metal. The tire carrier is 2×4 3/16 held on with a 1″ x 10″ grade 8. The bolt has 2 contact points and passes through 4 sections of the 3/16. There is a grade 8 nut welded in near the bottom. I also ran a seam down the path so that the bolt threads all the way down and used flanged bronze bushings to keep things smooth. The other side is a 9/16 grade 8 and another nut welded in.

The sides of the rear are 3/16″ square tube, capped and angled in the front and then skinned in the 10 gauge sheet metal. They follow the original rub strip.

The whole thing is mounted to a set of CUCV mounts with lots of 9/16″ grade 8′s and has CUCV clevis rings.

The gas cans are NATO 5 gals and the mount is 3/16″ angle iron. I boxed in an original Chevy license plate mount so thatI could retain the light for inspection purposes.
I custom made the hinge with 2 shear points after seeing and reading about tire carriers using the aftermarket hinges breaking.  I believe that my design is far stronger because of both materials and the double shear point.
