how well do these work? i just got a 10 inch lathe and want to try making
some centering rings with it

by **Phil Stei** » Wed, 26 Dec 2001 01:46:18

I've had good sucess with a combination of hole saws & a fly cutter.
A small drill press mounted drun sander helps too.

The only use I can see for a lathe would for small ones.

I use 'em all the time on the drill press to cut the center hole. It just
takes a few tries to get it adjusted, but works great. I've done 29mm up to
6" no problem.

I have a small drill press and I read on a package of circle cutter that
says "max speed 500 rpm" and the problem is that my drill press wont go
below 700 rpm... it would be nice if I could somehow gear the thing down to
like 300 rpm so I can cut centering rings...

by **Phil Stei** » Wed, 26 Dec 2001 10:11:14

I set mine as low as it will go & use a shield. It's a little faster
than recommended but it work well. Haven't had any problem at all.

BTW still looking for those jokes.

Be EXTREMELY careful -- the biggest risk is that the fly cutter catch
and there be damage to your hands.

They really should be used at recommended speeds.

I totally agree. That's the reason for the shield. Thanks for
mentioning it catching. I always use a clamp that is like a half a
pair of vice grips that bolts to the drill press table. The larger
the circle the more likely it is to catch. Especially when the hole
is almost all the way through.

BE SAFE USE A CLAMP and a SHIELD.

When Mountainside Hobbies had started producing my kits (V2, Sandhawk,
and so on) we used a circle cutter on a drill press to cut the rings.
Had no problems at all and our cutter also had the "500 rpm" warning.
And our press would not do less than 700 rpm. Ran 100's of rings on
that system without a problem.

I bought 2 fly-cutters and use a friend's drill press that I believe has the
lowest speed of 650, while the fly-cutter recommends a max of 500. I've used it
successfully, but I agree with the suggestions to clamp your wood down & give
the work your undivided attention; you've a fast spinning bar of steel that
could do some permanent damage to you if your mind is wandering. -- Richard

Ditto. Most of the benchtop drill presses go no slower than 620rpm. That was
the low end on both my old and new models. You really have to go to the big
floor standing units to get a lower speed. My recommendation is to use the
lowest speed you've got, and don't have your hands ANYWHERE near the fly
cutter. One hand should be on the spindle advance handle, the other is best
kept in your pocket!

Any body know if a speed control can further slow a drill press? Or where to
get one for a fractional HP motor?

Well, that's cool. My press goes down to 540 RPM. I think that will do it.
Where would i go about purchasing a shield?

Seriously good advice, and exactly what I do. After I power up the drill
press, my left hand goes in my back pocket. As respectful as I am of my
table saw, I'm even more so of the circle cutter. I consider it the most
dangerous tool I have. Even at 380 rpm on my drill press, the cutting blade
is pretty much invisible.

Not sure where to buy one but, you can clamp a heavy peice of
plexiglass to the table of the drill press. Be sure it's clamped real
well. MSCDirect.com might have them.

Also from my experience, the fly cutter grabing the wood & wacking
you with it is very common so be sure to a clamp the wood to the table
& keep your hands away.

Kevin,
I cut my centering rings from large pieces of plywood and I use the
drill press' tubular post as a stop for the wood. That way, I don't
have to clamp it down and can easily hold it by hand. I do wear gloves
and goggles, however.

Gloves are generally not recommended for working around rotating
machinery. A moment's inattention that might cost you a fingernail or
the skin off a knuckle with bare hands, can lead to the tool pulling in
your whole arm if you're wearing gloves.

Goggles, OTOH, are a necessity for any power or hand tool work --
issuance of two eyeballs does not imply that one is a spare.
