The Making of a Full Circle Crank in a Homeshop

That is my next goal Scott, build a stroker in my homeshop, for a six cube build. I think my machines are capable, and I have a press, don't know if the operator is capable though!



I got back to work on this three cube crank today, the rings are now epoxied in place. I clamped the crank in the mill vice and leveled it, then cleaned all surfaces thoroughly, and fitted the rings with a thin layer of epoxy on all contact surfaces.

How do you plan to keep the epoxy in place when you go to filling the voids?

 

[awol]

While the epoxy is hardening, I bored and reamed a hole the size of the crank stubs in a piece of plate. I will stand the crank up vertical in the hole, piercing a piece of cardboard, and then slowly and carefully fill with epoxy.

JB weld seemed to stick to cardboard pretty good.( I usually mix JB on a peice of cardboard) do you have any problems removing the cardboard?

Butter bowl lids.

He'll probably tear it off and face the surfaces of the stuffers in the lathe...

My butter comes in a stick.

That is kind of what I was gettin at. If there was something that JB wouldn't stick to as well.

I use foil duck tape in cylinders when I fill intakes and once it sets I just pull off the tape,works great and don't stick to it.

 

[awol]

There's two sides of the crank, maybe Ill experiment and try two different materials. The goal is only to keep the epoxy from sticking to the plate, the crank will be chucked back up in the lathe and both sides cleaned up. \/

What about wax paper on top the card board? Will jb stick to it?

 

[Deets066]

Or maybe a light oil will help, like oiling forms for concrete

Plastic mixing boards for autobody fillers work great for jb weld. Once it hardens it peels right off.

I have used aluminum roof flashing.

 

[jmssaws]

Does anybody use devcon anymore?
I gave up on it,just to hard to use.
I've been using quick jb and like it,you can grind it in 30 minutes.

I've been feeling poorly.

Why not a press fit on the weights/rings?
