Here are some pix of the brake drum puller I made several years ago.
I figured that simplicity, durability and ease of fabrication were
of primary importance, and I had some 1" steel plate and a damaged
122 front hub to work with, access to a welding shop and a fair lathe.
Here is what it looks like installed before pulling:



To pull, you just tighten the lug nuts uniformly around the brim of the hat.



If it doesn't pop first time around, take it off and put a spacer between
the end of the axle and the inside of the puller. Here's a pic of the inside:



Here is another view of the outside:



Since there are 5 of them, the lugbolts and nuts work pretty well. Such a
puller could also be fabricated using a couple pieces of plate and a piece
of pipe, but then you'd have to drill 5 holes, weld 2 places, etc.
Depth needs to be about 1½" to get enough bite on the lugbolts for the first
pull. If necessary additional spacers can be added to pull further.
Sorry, I don't have any of these for sale but if I got orders for 10 I would
make some. If interested, e-mail me and we'll negotiate.
