Cylinder jigs for squish band cutting.

[Nitris223]

Finally got the time to build some jigs to cut the squish band on any of the saws I have on hand and cylinders I most commonly work with.
Only had 2 pieces of 4" diameter aluminum round to use so I pissed around for a bit and made the jigs work for 5 different husky cylinders.
288, 372xp on one slug.
346, 55 on one side and 357/359 on the other side.

Each threaded hole is marked with the corresponding number of the saw series and I marked the side the exhaust is on so it's quicker putting the jug on.
I've never cut the squish band on my lathe before. Always cleaned it up with a used piston and sandpaper stuck to the top.
I have one AM hyway cylinder for a 55 that needs a clean up job on the squish band because it looks like they never finished the cut to the compression chamber. Nasty ridge left inside. Eneded up keeping the cylinder and got a full refund for it.

I hope they work out to use in a 3 jaw chuck. If need be I can use the 4 jaw.

You’ll definitely need to use it in a 4 jaw independent chuck in order to square your X and Y axis with a dial indicator

I've made a few square uni-plates with a ton of holes in them. Then use a 4 jaw independent to get it centered up.

Trying to get the cylinder to line up on a 3-jaw will probably not go well.
