I'm sure I'm not the first to think of it duh but I wanted to share how easy it was to transform my gramil into a hand powered circle/rosette cutter. I needed one for my latest rosette, I needed to be able to see the blade and work right up to my mark. Pictures attached. Clinton

That's a nice idea, and it's one of those things that is painfully obvious after someone else points it out to me. I clearly see the advantage of being able to see precisely where your knife tip will touch the wood. That's great. I believe I see a pin bushing in your wood block. Is there anything special about the thumb screw? Did you just thread the wood for it, or do you have a threaded metal insert in the block?

Thanks for posting this!

That's a 1/4" brass bushing for the pin and I just threaded the walnut for a 1/4" thumb screw. I torqued it down to see if I could easily strip it, it's surprisingly strong! Clinton

On the subject of gramill, where can I get one cheaply? The only one I saw is at LMI and they're a little more expensive than I like...

Weigh the time and materials to make one, and you'l quickly find that the LMI Gramil is a very reasonable price. The blade is also a Hock blade, so it's great quality.
