Timber Framers Guild Forums Tools Tool Forum Looking for some tools

Hello all,

I am looking for used 13" saws (makita or hitachi) as well as a used makita groove cutter or some other miracle tool for cutting several miles of 3/4"x3/4" grooves in oak timbers. If you have something, let me know.

Thanks,

Gabel

Have you considered a 5" ajdustable dado blade on your husky 7.25" saw with appropriate jigs/guides for getting the groove where you want it ?

I was on a job site a year ago or so and saw this groove cutter:



I think what the carpenter did was he got a longer bolt for the saw arbor and just used standard saw blades, then offset them so the teeth went in between the teeth of the adjacent blades.

It seemed like a simple solution to making a wide blade cutter.

I don't know all the fine details but it shouldn't be hard to do if you can find the right thread bolt for your standard skill saw.

Thanks for the replies and especially the picture, Jim.

How accurate does your groove need to be?
It seems to me that if accuracy is an issue you could have some shims made like the ones used with stacked dados. Used with the set up Jim shows you could adjust your width
Should be simple and cheap at the local machine shop

Hey John,

That's a good idea-- I was thinking the same thing myself. The groove needs to be pretty accurate.

Thanks and keep the ideas coming,

Gabel

A closer look at the photo of this dedicated saw shows he removed the guard to get enough room for all those blades.
He may have removed the inner washer also, it's hard to tell.
He works nearby and I could go see him again and get more info if you need it.
Just let me know.

Jim-Funny you should point that out. I was looking at my saw guard today and thought "so now how would THAT work?"

Gabel-Alternate plan. What about a stacked dado with a bushing to adapt it to the skill saw? It would probably require an 8" or larger saw but if you already own one..

Don't let Gordon see any of this......

John, and all this time I thought Gordon was a brand of scotch.

John,

I was just thinking that I should probably not tell anyone even if I do try that. And I should definitely leave it at home for the next rendezvous.
