Circle cutter for wood or thin sheet metal

Well, you *could* mount your cutting tool in a boring head, which is dead easy to hold a thou with ..

What lever of accuracy are you looking for and how are you going to drive the cutter. A cutter driven by a drill press or vertical mill could easily be a single point device while a hand drill might work better with a multi tooth cutter.

Just the picture should be enough for about half the guys here to make one. the other half would buy it because they were too tied up in another project, or they were not yet equipped with tools and experience to feel confident enough.

Thanks all,,,,,Trevor Jones found exactly what I was looking for and he is right I probably will make one instead of buying it. I like the way it adjusts with a threaded knob.

Thanks to all, what I did instead was to use my Bridgeport with a large rotary table covered with a piece of sacrificial wood. Then I used a 1/4 end mill and clamped the wood to the table and cut away my needed 1/4" wooden circle with a large hole in the middle of it.

Thanks again.

I think that is known as a trepanning tool.

I use a boring head myself. It is set on a scale and by actual measurement after that.

Mart> Does any one know of a micro adjustable circle cutter similar to the

You shouldn't put yourself down like that, Martin. There are plenty of idiots who'll do it for you!

D&RFC ;-)

I didn't look at Trevor's link, but I suspect it is the same item that Grizzly sells here in the states. See:

Very same! Probably came across in the same sea can. The owners of Grizz are rumored to be related to the owners of Busy Bee.

I just have a very warped sense of humor. It helps me to put up with a lot of crap! :)

BTW, any day you don't laugh, isn't worth getting out of bed. :(

I have become heat intolerant due to some medicine, so I was already trapped inside when all the smoke blew through. It was even worse a few years ago, when all those fires in Mexico were drifting across the Gulf, and into my area. That was so thick it seeped inside, for weeks.

I couldn't believe it but at one time the sand from a Sahara dust storm was coming over south Florida. It was doing a lot of damage to the aircraft engines.

That fine sand is bad on a lot of other things, too.

Yeah, humping your girlfriend on the beach can be downright dangerous. We don't want to be sanding down our newly-found 15.2 cm of manhood!

Actually, I was talking about car engines and people's lungs, not to mention damage to windows. I used to clean a handful of sand out of the breather on my car every month or so.

I put a couple grains of masons sand in a buddies jar of vasoline as a prank once. His girlfriend wasnt amused.
