Re: Technique for parting a part

Rob and all--I use superglue (cyano-acrylate or CA) quite a lot for
fixturing parts that don't lend well to normal clamping or holding
methods. (Within reasonable limits of machining force) The thicker
grade (syrup consistency) works good, make a few small puddles and
set the part down on a flat sacrificial plate of aluminum, mdf or
whatever. Aluminum seems to work good as it seems to hold well and
can be scraped clean for the next part. A knife tapped into the glue
joint will seperate it after machinining your part(s) In the case of
the box example, the part and the scrap can both stay glued down
until finished machining. Anyone else do this?
