Grafting feedscrew (Q from a new guy)

For an interference fit like I suggested you'll have to heat the shaft quite a bit, (probably shoot for blue heat) loctite would be evaporated. Can run the numbers for temperature and expansion if your thinking of going that way. If you were to pin it a tapered dowl would be best. You'd need a tapered reamer to prep the hole for the dowl
