I use some Slitter saw blades I got from a Car Boot sale 20 years ago They are 4" dia 1" bore and .025" wide ..The're sometimes found on E-Bay.Timbuck,
Where did you source your blade?
Thanks,
George
British Films were always crap...Why should I change the tradition???i find this video to cause me great pain
My drill setup cuts at 2500 RPM with a 100mm dia: blade...It's ok with Rosewood, but drags a bit on Ebony but still do's the job....The HSS blade is designed for slitting steel and other metals at lower revs and feeds, but at high rev's it handles the fingerboards quite well...And due to the small diameter of 100mm there is very little harmonic viberation in the blade and it reduces the problem of the slot opening up at the edge as the blade enters or exits the slot.What do you think the RPM's should be for cutting slots in a board? You can get jeweler blades at .023 thick, which matches StewMac slots and fretwire, from online industrial.

I used a strip of alluminium angle marked it out with a vernier calliper and a magnifying glass...carefully punched with a prick punch followed by a centre punch and drilled with a 1mm bit followed by 2.5mm bit..if you're carefull you can be within .005"Excellent jig. I would have to get the indexing template machined somewhere. I'm using the LMI template right now but I'm thinking this might actuall be a time saver. Something to keep in mind. Thanks Timbuck!
Just found the blades on E-Bay...http://cgi.ebay.co.uk/Slitting-Saw-...tZUK_Hand_Tools_Equipment?hash=item22f4bb0c94
Correct you just mill the slot out..you don't go very deep so chip clearance aint a problem.Can I assume that these blades have no set to the teeth, and a .025 blade thickness is the same as the kerf produced?
