Curve cutting jig

Good idea! I hate having to put a hole in my workpiece! I’ll have to give this a try.

The flashing thought struck me that maybe we are not as far apart as our politicians make us believe.
Not being a “structured” religionist I could be all wrong too.

Great Jig we used one like it when we made the baby cradles for the “Toys for Christmas” program at the Mason Dixon Woodworking Club.

I saw an arch cutting jig on one of the woodworking shows – I think it was “This Old House” when one of the guys visited a window making shop. They drilled a plank perpendicular to the stock, cut the outer edge and then moved it in and cut the inner edge.

When I saw Peter’s pattern jig that uses hold-downs instead of drilling into the stock, I merged the two ideas and came up with a small version of the arch cutter, except it’s not for cutting arches, just a curved edge.

I like this jig, and I am gonna copy it. I guess that old saying “necessity is the Motherhood of invention” is true. Woodworkers sure are a clever bunch.

Good idea! great use of hold downs to save making a hole.

Bob – I totally agree, world leaders sometimes just can’t seem to “Get it”

Cajunpen – I’m glad someone else can use the design – it is VERY secure with the hold-downs.

Herbr- I had been thinking for a long while how to avoid making the hole, then I saw Peter’s pattern making jig. I had originally thought that I would have to you double-sided tape all the time – that was dumb! Not to mention not very secure.

Thanks All!

Sehr gut. I used to work in a factory making dental chair bases, the swivel mechanism of which sat on a small solid aluminum pedestal. The stock came in square blocks of metal, which the Machine Shop drilled, but then it went to Grinding and Polishing to round the corners and put a finish on. I was in Assembly, but the guys in G&P would work for a quarter hour or more trying to round the corners on one piece, and usually they ground off too much metal or it looked dorky, and I needed the parts, so I’d go over and do it myself. Somehow I had the knack of being able to round the corners so that it looked as if a machine had done it, and it took me about a minute or less per piece. Unfortunately I couldn’t explain how I did it (and still I don’t know myself), and the way I did it didn’t let observers see it—I had to stand in front of the grinding wheel, holding the workpiece waist high in both hands, “jiggling” it up and down very slightly while turning it back and forth—I said I couldn’t explain it—so nobody could watch. The point of this whole sordid story is that when I tried the same thing with wood, it didn’t work—did you know that metal and wood have different grains?; a jig like this might have solved the problem at the factory, and would definitely serve if/when I need to do corners on wood again.

Looks pretty stinkin’ useful to me. Going to have to make one, even if only to decorate my shop wall with another nifty jig. Thanks for the tip!

Have you ever thought of doing that task with a router and straight bearing bit?
I just take any circle(glass or jar or can etc) that has the approximate curve and line it up on a piece of plywood on the corner. I cut the corner to the shape and use the plywood as the template.
I can see you have several center points on your jig so that may not be much of a problem for you.

Cheers

Yeah Bob, that thought did come to mind but I don’t like using the router for cutting or dado-ing. Just personal preference. Also I don’t really like using the router to finish off the edges after rough cutting. I just prefer to cut and proceed to sanding.

This jig is for a very limited purpose and I very much prefer to use the band saw as opposed to a router when I have to cut 20 or 30 of these.

I will add this one to my collection of jigs. Thanks for the idea

Any chance you would share details of your circle cutting jig…I’ve looked and looked, cant find anything I like.
