I'd like to find, or build, if I can, a nice hand rosette cutter. Do any of you have a pattern or good picture of something?
I ran out of popsicle sticks, but summer is coming.
I found this on R. De Bondt's site.

I have the one from LMI ( http://www.lmii.com/CartTwo/thirdproduc ... cle+Cutter ). It works well. They're charging around $80 for it but I got mine in more or less unused condition on ebay a couple of years ago for around $50 (they don't come up too often, though). Before I bought this, I used a cutting gauge that I'd modified with pretty good results. you can usually find these pretty cheap on ebay.

That is a nice cutter, but I've always love this one from Geza Burghardt! Maybe one day...

Doug, that is what I was looking for, thanks.

That one could be built mostly out of maple and a brass shaft to hold the knife and end roller.

Anyone know where to get all the roller parts from, or are all these parts on both these home made? I am talking about the 'wheel' micro-adjustment on the bottom one, some of the nuts, etc. I would like to add some hand adjustment knobs to my setscrews, maybe a micro-adjuster like the one above. Good store for that kind of stuff? :ugeek:

a bearingm like the backing wheel bearing on a bandsaw, would work.

Now I'm starting to want to make one. Darn, something else to distract me...

Im thinking the brass adjustment stuff on a Stanley plane. I also need some knob thing to go over the 2 set screws, some kind of knob. idunno Or I could drill out my own knobs, of brass. Just need something. Could maybe make knobs out of round brass stock, but they would be crude. I know they must make some kool knobs out there. :?

The General Circle Cutter is a decent base to work off of, and its soft (chinees), so you can drill it pretty easy. You need your hand over the blade area, and to balance the other side basicly.

A number of us here (Joshua, Waddy) have made ones similar to this one, which I use to define the edges of the rosette channel even if I'm going to rout out the channel. On my pure hand builds I use I to make multiple cuts inside the channel then chisel out. Takes about an hour to make.

This one is BRW and cherry.

I have a Dremel Circle cutter I got a few years ago in a kit. I've never cut a rossette but the need is coming.
Make a hand tool or convert the Dremel circle cutter to need?

That's a nice one, Colin, sort of vertical as opposed to horizontal.

I've done several rosette channels with just a stick, nail, and xacto blade, and would love to move up to something more solid.

Not that I'm retiring the dremel, I just enjoy quiet time.

I'm cobbling one together based on Lie Nielsen's inlay circle cutter. Just couldn't bring myself to pony up $85+ for their tool, so I bought the rods and a replacement blade from them. I have some phenolic that is thick enough to use for the body. I opted to go with their rods because they come tapped and threaded. The screws that hold the blade in place screw into the arms, holding it all together.

This is the cutter taken from Lie Nielsen's website.

I built this one based on a drawing in a guitar building book I thumbed through in Barnes and Noble last year. It worked fine for me - I didn't make it super accurately (which I now regret). But I have also used it to cut the binding and purfling channels on my guitar.

I started out using Xacto blades, but they are brittle and didn't cut very well at all! (I tried both the standard blade and the round nose blades. Then I made my own blade out of and old sawsall blade and it works GREAT.

You can buy 18" - 1/8 or 1/16 tool steel for like $15.00 - Kinkead in his book used an old hacksaw blade.

I just made a 'grinding wheel' from my old Milwakee drill, router adjuster, and some $2.00 grinding wheels. They take water well so they don't overheat, and work better than a borrowed grinding wheel I used, because I can keep the speed down to 120 rpm! I should post pics, I am just so lazy this week.... idunno Eat Drink
