I'm collecting the famous women's quarters and want to make a display for them, and I'd like to turn this on my lathe. Bear in mind I'd have to make 4 (one for each year of the distribution). I haven't seen any other display designs for these so I concocted my own. Here's what I'm thinking. There will be a circular frame that holds a piece of plywood with an attractive veneer covering it, probably 1/2" thick. Each display will hold 10 quarters with a brass plaque in the center with their names engraved on it. The frame will be 13" OD, 10" ID and composed of segments. I'm thinking 2 identical rings (1/2" thick) with the segments offset to have the seams centered on the adjoining segment...that allows me to skip splines or some end to end joinery on the segments. So here's my question: how would I hold this on a lathe to turn it round and then turn some embellishments on the face of the frame. I could easily do this with a router but the lathe would be more fun. I have a set of cole jaws but not large enough to hold that size ring. Maybe glue (or fasten with short screws) the ring to a piece of plywood and fasten that in some fashion to the chuck, then cut it off after the turning is done???? Anyway, my sketch of the basic, the ring segment calculation, and the segment are shown. PS: hope this made sense.

Couldn't come up with a great topic title but you will get the idea when you read the post. Today I was working on an eagle pattern using 3/4" walnut. When cutting the feathers, it dawned on me that the "non cut area" around most of the feathers was really slim. Hmmmmm, 3/4" material and only a 1/16" left between feathers - could be in a real mess when looking at it from the other side. AND, this eagle is a free-stander - both sides will be viewed. Got me to thinking: Is my blade perfectly perpendicular to the table? Is the tension ok? Do I have the right blade so it won't bend in the middle? Am I pushing too hard? Am I pushing absolutely straight into the blade? Bunch of questions I couldn't really come up with an accurate answer. How else could I solve the problem of the cut looking the same from the front AND the back? "Turn on the bulb, mister ", I said to myself. "I think we just might have come up with an answer. Well, at least it's an answer." PLAN THE CUTS - Planning the cuts so that I will be cutting in the same direction on both sides (left and right) of the narrow part. Same angle on the blade ! ! ! ! Then ease up on the pressure. I'm sure the the blade and tension are right. Then, as old men tend to do, I got myself cornfuzed with which direction was shich. I then got out my trused pencil with a sharp blade and started marking the directions I would be cutting. VOILA - it worked perfectly for me. Both sides look good, no messy spiders on the back side. Maybe this trick will work for you.......................... If you have another idea for this dilema, let us know..................... Thanks for taking the time to read this little tid bit. Fred
