Let me add something about the td sleeve, maybe someone is interested in:
This are homemade sleeves from a pipe with 42mm diam.. I had no matching pipe handy for an inner tube, so I used the same pipe, cut out a strip of about 4mm lengthwise and bent it again to a circle. Both parts were bent then the vice. In this case I cut the inner tube in an 45° angle, of course the wood in the outer sleeve is also cut in that angle. This little trick works great!
For glueing in epoxi is best, because of gap filling.
