Diff yoke tool for torquing pinion?
 
Combination door panel remover and pop rivet head cutter.
It's tapered and sharp between the prongs and cuts the heads off door hardware pop rivets clean and flush.
I made this probably 25 years ago.

Go ahead, there's your next million.:D

Couple good guesses. Here is a hint, magnum engines...
I'll post up a pic tonight

My big "F" is used to hold the water pump pulley while the fan clutch is loosened or tightened. Works good, leaves what little room that is there for the fan clutch wrench.

Good idea. I remember taking the fan off my 93 318 when I had to replace the water pump and man was it a bugger without anything to hold the pulley. Finally got it using the impact method. Put my big ole wrench on it and smacked it 3 or 4 times with a 2 lb. sledge and it popped loose. Tightened it the same way. Not the ideal method but it worked.

LOL - I did my first one the same way. I need to replace the fan clutch on a friends 2003 Dakota next week. Told him I would do it after I made this wrench...

My meager attempt at a homemade A arm bushing tool.

Got a steel pipe coupler. These are normally used on the ends of 20' lengths of pipe for thread protection. Around here, only malleable iron couplers are used operationally.

I clamped it in my Drill / Mill and cut a notch for clearance. You don't need a mill, you can do this with a hacksaw, as it's not critical

The bolt is a scrap of 1/2" allthread.

I bought some (called locally) "flat plate washers." These are not only very large OD, like a fender washer, they are thick as can be, maybe 3/16" ? "I used two" LOL

I could've gotten the new ones in, but the arms really should be cleaned up

THAT is not a homemade tool, LOL. THAT is an engineering prototype!!!
 
just made my sheet metal brake this last weekend.



bends meterial up to 1/8" x 36" wide.

Nice. I like the seat mount too.

(Check out my thread to see how I used your spring slider idea)

Nice job. I don't do much differential work anymore so I don't need one of these real bad but I have a couple rounds pieces of steel that just fit into a 8-3/4 carrier bearing opening so I may have to dig up some round rod and make one of these.

Thanks this thread gave me some good ideas. Maybe some one can get some good ideas from what I've made.

1: Degreeing wheel made of a degreeing wheel printed on a 11 x 17 inches paper then glued on a pizza cardboard. Took a welding rod that I've bent to a pointer.
2: Piston stop. Using it when the head is removed when I degreeing a cam.
3: A copper pipe flattened. Placing the flattened copper pipe thing behind a hole then welding the hole together without the weld sticking to it. On aluminium use a flat steel piece behind instead.
4: Steering wheel puller.
5: Modified puller to pull the steering column thingy.
