WTB: kerf Saw blade and arbor for small-box hinges

Anybody have this .035 width tiny blade and arbor to use Rockler's barbed hinges for small boxes? Do they work? Want to part with them?

scroll down past the hinges for the blade and arbor.

i saw boxes made with these the other day and wondered how they cut the slots for the hinges.

So what tool does the blade and arbor mount in?

According to the site, a drill press. You can get a pdf with blade sizes on the middle tab. I wonder how much pressure you put on the quill though, since it really isn't designed for lateral pressure?

they say drill press, but it is a 1/2" arbor, so I was going to try a router table. I wanted to buy from some one that bought one and isn't using it, because the cost for the blade ($40) and arbor (another $40) is outrageous. the hinges are about a buck each. I think I found the manufacturer's website - they want $35 each, but they also want $12 shipping.

RPM for a router vs. a drill press are substantially different. Unless this kerf saw blade can run at 8000-10000 RPM, don't do it. I'm not aware of a router that would run at normal blade RPM (~3500-5000RPM).

However - what are the chances of these hinges working in the kerfs made by biscuit joiners?

BJ use kerfs like around .150 or .170"... The hinges are .035, considerably smaller.

The blade speed would concern me. DPs rarely turn more than 2000 RPM, that would be fast for a large diameter item.
Routers, with variable speed, rarely turn less than 5000 minimum, and many more have 8000 RPM minimum speed.

those are good points about the router speed that I hadn't thought of. That's why I am glad to hear all your opinions.

But if I want to get the blade, looks like I'll have to bite the bullet and pay the $80.

As an alternative, you might be able to do the kerf with a slot cutting router bit, and make a template.

No, you must not be familiar with this system. the slot is not much thicker than a piece of paper.

You're right, I haven't used them. The thinnest blade listed is .022, there may be a slot cutter that might work. The next blade is .032, which is like 1/32"...a bit more standard.

Have you looked at the Dremel saw blade & arbor. This one is .023. You could chuck it in a drill press. It might be less expensive and close enough to work.

[agent511]

no , cabinet man, you are still a little off.

.032 is not 1/32" . It is 3/100ths of an inch. 1/32 is around .06

I doubt there are slot cutters that are thinner than 1/64 of an inch. I have never heard of such a thing. hence the existence 9and cost) of these cutters.

Your math is a little off.

1/32" = .03125
1/16" = .0625

I haven't seen one of these either, but from the pics., I wouldn't expect 0.023 to work if 0.035 is specified. The hinge is essentially held in by friction, so kerf width is critical I would expect that teh hinge wouldn't be able to squeeze into a 0.023" kerf

[agent511]

My apologies, my math was off!!

There is a smaller hinge that works with the .02 blade. The Dremel blade may indeed be a cheaper option, worth a try.

Thanks for that tip.
