Purfling Cutter

[charlese]

Here is a stanley 66 beading cutter that does the same cut but with a curved fence.

I have tried endlessly to embed a pic. Can someone straighten me out on that?

Really nice job!!!!

I have a question wouldn't a small (very small) hand held route with an edge guide do the job better? It would cut the channel and clean the bottom in one operation.

Perhaps it is Norm (New Yankee Workshop) versus Roy Underhill (Woodwright Shop) One uses power everything the other doesn't use any power other than himself.

For me, I prefer to make my mistakes at much lower speed. Things start to go south you have so much more time to recover.

I am not a professionally carpenter. But, i haven't much experience that's why not familiar with the tools and also don't know, how they work. I have seen the purfling cutter, but don't know how and why it uses?

From the first post: "I described a cutter that could be used to cut a channel for purfling; that's the strip that goes near the edge of a violin or guitar. Most guitars have edge binding, and a single knife would do, but for a violin, you want to have a nice channel to inlay into. "

Holsgo, that tool looks like a manual router, like an old Stanley tool I have seen, but with a scraper blade; very nice. The purfling cutter only cuts the sides of the channel, it doesn't clear the chip. The danger in cutting a purfling channel is that the wood is so thin at that point that unless you are really careful, you can tear the whole side off!

So, I make a shallow cut around the edge first. The ability to change the direction of the knives lets me cut across the grain most of the time. Once I have made a shallow cut, say 1/16th", I use a narrow chisel to clen out the chip. then a little deeper cut. The tool doesn't have a depth guage, that might go in version #2.

As I said earlier, the heft of the tool makes it a pleasure to use, not too light that it will take off on its own.

Check this link for a good definition, and a video of a similar tool in action: http://thequartetofpeace.blogspot.com/2 ... wn-is.html

This page also makes clear the a good reason for the purfling is to ensure that edge knocks do not become cracks!

Wow that's craftsmanship. As a novice guitar builder I can appreciate the patience and skill this takes. As a hand engraver, I can also see I may the hand eye coordination to accomplish this type of work someday. For now, though, I KISS (Keep It Simple, Stupid). I have too many irons in the fire and only wish I had more time to do all of the things in life I wish to do.

Many of you had nice things to say about this tool http://www.shopsmith.net/forums/showthr ... ing+cutter. It is, unfortunateley, the last I will get. Dave passed away at home a week ago 1 week shy of his 70th.

I posted some of the pics on FaceBook and some of the rest of the family and his friends got to see some of the amazing work he did. I am going to miss Dave, but using that tool is going to give me more than just woodworking pleasure now... it is going to be a continuation of our last conversations together; and nothing would make me happier.

We couldn't make the memorial service because of distance, but I hear that the place was packed. Dave had that effect on people, he just couldn't help but make friends.

Glad I got to show you all a piece from a true craftsman, who sadly is no longer with us.

Hello,

I always enjoyed this topic. Many thanks.

I've decided I'll probably need something similar for an upcoming guitar build. But the guitar (as compared to a violin) won't need to veer as fast, and therefore the cutter can have a larger-radius 'fence'.

I have a very nice Cutting Gage that came as part of a Lee Valley / Veritas string-inlay kit. It has worked wonders for me, and it's heavy. I just fabricated an add-on radiused fence, from hard maple. Some time from now, I'll see how it works I may not use it as a full cutting implement, but at least I can use it as a line-striker to protect the wood from tear-out if I used a power router.

A brief follow-up;

I got around to using this in the guitar resto-mod I've been working on lately. I had to modify my adapter block for greater depth and smaller radius. It does work now!
