Topic tags/keywords: question ftg tablesaw

Hello LJs. I have been reading KnotScott’s great reviews of TS blades recently but I have a very specific request of the community. I recently attempted one of the Doug Stowe-type keyed miter boxes with my generally quite adequate Freud Fusion combination blade, but the ATB grind of this blade leaves a disappointing cut of the key slots.

That said, I know that there is a Forrest WWII out there with a FTG, but until I win the lottery, or it’s time to buy another go-to blade, I’d like your recommendation for a blade that is:
1). Cheap as this is for a very limited application. For this purpose a full kerf blade seems desireable.
2). Not so cheap that it will throw teeth, sound like an approaching tornado or shimmy like your sister Kate.

A buddy of mine gave me his stock (came with the saw) Delta ATBR and it was so evil sounding that I shut it down right away. To be fair it had not been stored adequately (thrown into a cat litter bucket filled with saved offcuts with no cover, at an angle etc). I truly don’t want to spend much here – just wanting a carbide toothed blade around 25 or so bucks. Any thoughts?

Doug, what about using a dado blade? That should produce the type of kerf that you are wanting to cut.

Doug, if you send your blade (yes, even the Freud) to Forrest, they will grind it flat for you fairly cheap…..

Or maybe buying a cheaper blade and having them flat top it…...

BTW, they also can grind a custom bevel on teeth so that you can cut dovetails on the tablesaw, ie flatbottomed bevel cuts! :O

Scott, dado blades are angled in…..the overlap of the chippers give them a flat bottom…..Most of them anyway….

Hi Douglas – Glad to have provided some midnight reading for you.

A full kerf FTG blade is typically going to be available as a 24T ripper. Most blades beyond 24 teeth tend to have a grind that’s either TCG, ATB, or ATB/R, and none of those grinds leaves a perfectly flat bottom. Bosch does have a 60T FTG thin kerf on sale from Amazon for ~ $31 shipped…CB1060L. I haven’t tried that particular blade, but it should cut. Amazon also has a new line called Kempston that I haven’t tried…they look like Freud knock offs. They have a 10-inch 24T FTG ripper < $30 shipped, and they also have an 8-inch 24T FTG”:http://www.amazon.com/Kempston-99310-8-Inch-Industrial-Coating/dp/B0013KTUPC/ref=sr123?ie=UTF8&s=hi&qid=1237766948&sr=1-23 for < $27 shipped. Infinity does have a new box joint/flat bottom crosscut blade, but IIRC it’s around $60. There are likely others that I’ve overlooked or don’t know about. The next best thing to a flat top grind would be an ATB/R, and ATB with a low bevel angle of ~ 10°, or an ATB/R….lots of choices in those, but none will give the true flat bottom, and most will be over $25. Good luck!

No doubt the Freud fusion is not the blade for this task First thing I thought of was what Scott said about using a dado blade, but I think knotscott knows his blades, by the way no more references about my sister Kate.

I second Scott’s recommendation with regards using a dado blade, that’s what I used doing the Stowe boxes and it worked a treat.

Oddly, the only dado I have is a wobbler I bought with my first TS (a Craftsman) in 1991. All the dado work I’ve done with a plunge router or with the Incra fence. Might have to go with the Bosch and use thinner key stock or the Kempston etc.

Adrian's signature line- “THe 11th Commandment….. Thou Shalt Not Buy A Wobble Dado” says it well. I thought about this situation when I posted my comment. I am sure that I bought the same wobbler with my Craftsman saw as well. Needless to say it has been on the shelf since shortly after I bought it (once again I violated my personal philosophy of buying on the basis of quality rather than price which invariably has ended up costing me more in the long run). Once you go with a stacked set you never go back.

Hey Doug, I’ve got a dado wobbler still in the package, never been used. I’ll pay the shipping if you want to try it…...snicker

Thanks for bringing that up Scott (and Mike – you scamp!). That is where I first became of Adrian’s fine properties as a gentleman and an LJ. It also allows me to repost one of my favorite LJ “art” projects.
