Spare Parts #11 - Making A 4 Flute Light Duty Dovetail Cutter
Added 2015-12-24 12:02:08 +0000 UTCThe "Impossible Dovetail" project requires a rather unique narrow taper dovetail cutter. So in this video I make my own from oil hardening (O1) tool steel. Enjoy!
Cheers,
Chris.

2015-12-24 20:09:06 +0000 UTCYes chip relief, although if I was to do it again, I would make it two stage - a short "flat" section, followed by the chip relief. I unnecessarily weakened the tip by making it one stage.It's been wonderful having your support this year PJ, from the very beginning you have been so very encouraging and supportive - Thank you my friend.

2015-12-24 12:31:11 +0000 UTCVery interesting, quick question, why didn't you form the relief angles before heat treating it? I would have thought that would have meant you didn't have to worry about heating it up at the grinder?
