fastening material to waste block - methods

[Gary Pool]

I would recommend CA glue....both hot glue or double sided tape are flexible adhesives, and you will get vibration when turning.

How would you part the glued pieces when using CA?

If you use CA with accelerator it makes the joint brittle. You can break the joint easily by driving a chisel through it. It's not the wedding action tgat does it but the impact so hit it hard. It will often break at the glue line and leave the wood on both sides intact. If not it pulls very little wood out so its easy to clean up.

... double sided tape are flexible adhesives, and you will get vibration when turning.

Not trying to be argumentative here - just relaying experience.

My friend who has been using double-sided woodturner's tape on faceplate for decades said he has never experienced vibration even with large heavy pieces and with aggressive turning. He carefully cleans the faceplate and flattens the contact surface on the wood before attaching.

When both a machinist friend and I use it to hold parts for precision machining on a mill we also had no measurable irregularity in the finished surfaces. Surfaces are checked with a precision dial a test indicator. Granted, fastening a part to the bed with clamps is the traditional way but this can't easily be done in some cases. I've used this on my mill but not the metal-turning lathe.

We suspect that using the proper type of tape, and applying it with under significant pressure for a sufficient amount of time, and on machinery without significant play eliminates any such problem. Note that the entire contact surface is covered with non-overlapping strips of of tape. Could be different if both surfaces were not clean and flat and not applied with care or held buy a non-continuous layer or some strips were overlapping. Haven't tried these so this is only a guess.
