Take two pcs of scrap plywood, and run two or three sheet metal screws through them, so the tips of the screws stick out. Use these to support the blades, the screw tips only leave a small spot in the varnish.

: ...how do you support it? I've been making them with epoxy coated tips, so
: I've avoided this issue to date by not varnishing the scrificial tip
: coating. I'd like to put a full coat of varnish on my latest one and I'm
: stumped. The only thing I can think of is to put brads or pins in the
: ends, then fill the holes afterward. Is there a better way?
