I think I have been reasonably successful, in general, in developing a method for CA finishing.
However, one aspect continues to bug me.
I turn between centers, using steel cones in both headstock and tailstock, and I use those when sanding and finishing also.
When applying the CA, I drip the CA from the bottle, held above the very slowly rotating blank.
At the same time, I lightly rub the underside of the blank with polyethylene sheet to distribute the CA over the blank.
The CA always gets onto the steel cones and tends to bond the blank to the cones at both ends.
After applying a few coats of CA, the nicely shaped blank is well and truly stuck to the steel cones.
Therein lies the problem ... because getting the blank unstuck from the cones sometimes damages the CA finish.
I am wondering if I should machine some polyethylene cones to replace the steel ones. . CA does not stick to poly.
Any suggestions would be appreciated. . . Or any alternative ideas ?
If you think that polyethylene cones would be a good idea, where would I buy some poly rod to make cones from ?
