StewMac fret blade arbor size
StewMac fret blade arbor size
G'day again,
Two questions in one day, hope I'm not exceeding my quota Just shows that during the lock-down I'm finally making progress on the now 2 year acoustic build.
I bought the Stew Mac table saw fretting blade (https://www.stewmac.com/Luthier_Tools/T ... Blade.html) and went to fit it to the table saw yesterday only to discover that the blade has a 5/8" arbor but the saw is 20mm.
Anyone else had the same issue and can provide some advice?
(I'm guessing I'm likely going to have to go to a machine shop and get them to bore it out).
Cheers,
Iain

You can get adapters. Here's one from an American supplier: https://www.mcfeelys.com/saw-blade-arbo ... 13287.html

Re: StewMac fret blade arbor size
Ok I thought it was other way around. A machine shop should be able to machine the blade hole out to 20mm.
Thanks Martin,
If only it were that easy I actually have the opposite problem to that, the arbor on the blade is 5/8" and the spindle on the saw is 20mm so the arbor needs to be larger on the blade i.e. honed out to fit the 20mm of the saw/drive.

Re: StewMac fret blade arbor size
You could set it up in the drill press. Block of wood underneath it, clamp it down and drill it out to 20mm. The local engineering store should stock drill bits. Ask for a 1/2 inch parallel shanked, 20mm drill bit.
Re: StewMac fret blade arbor size
It is very difficult to drill or ream or machine the centre of a saw blade, anything slightly of centre and you will have balance issues, cut issues and so forth.
Maybe consider getting a drop saw, that is what i use.

Re: StewMac fret blade arbor size
It's a job for a machine shop.....they can mount the blade so it's centred and then make the hole bigger. Sometimes the teeth will need a dress up if the blade is slightly off centre

Thanks all,
After a couple of calls this morning, Central Saw and Knife Works here in Adelaide are able to increase the bore size for me.

Definitely a job for a machine shop. The blade is fully case hardened. I got a shop to do mine years ago and they even broke a bit on it because of how hard that bore was

Thanks Phil.
Crikey, hope I'm not going to experience wallet shock when I go to pick it up tomorrow
