COM8 Budget Frame Center Ankle Fix

Last week I helped Johnathan fix his COM8 Budget frame. Due to a misunderstanding of club measurements the frame had to be tweaked to allow the center ankle to recess into the body.

I’m sure a lot of people are going to be doing this, so I thought I’d share how Johnathan did his. The thinking behind keeping the hole as small as possible (vs matching the larger skirt opening) was to keep as much material and strength as possible in the lower “ring”.

We marked out where the ankle needed to go (and added a little wiggle room), and simply cut out the hole using jigsaw with a medium tooth blade. We finished off the edges with a file and Dremel. Johnathan later drilled some holes for the new additional ankle mounting plate.

Center Foot Wedges

I had to add some wedges/stops to the side of the ankle to stop the foot from tipping when going in reverse. As usual rather than reinventing the wheel I copied Victor.

I made a quick paper template that I traced directly from the ankle/foot. I then cut them from some scrap 1/8″ aluminum I had sitting around.

And finished them of with a clean coat of white (including the screw heads)

I tapped the side of the ankle, and also included a wooden block inside (also drilled/tapped) just in case the ankle wall thickness wasn’t enough to hold the screw.
