I still will need to figure out how to resharpen the router bits I use on the spirograph since I hog so much out in each pass that I tend to get the bits dulls quickly.I dont want to invest too much money this is for my home workshop.I have seen several in catalogs made by Grizzly, Woodtek, Delta (expensive), and Vega which has several models.Are there any tool reviews on these models I understand that Sears also made one but is now out of production.
Jet Wood Lathe Duplicator How To Resharpen TheA skew chisel and spindle gouge will take a lot of material off in a hurry. Nobody will spot a few hundredths of an inch one way or another unless they are looking REAL close, and perhaps not even then. I just rough the parts to their largest finished diameter, then use a board with pencil notches at the high and low points of the turning to do my layout. Then I use a parting tool and calipers to cut to the proper diameter at each layout line. You might take 15 or 20 minutes to do the first one, but by number twenty, youd probably be well under ten minutes each. You can actually rough out and turn a lot of shapes with just a skew chisel, but thats another discussion. I know a couple of guys that have them and are happy with them. After cutting about twenty of the same pattern you will start to get the feel of things. Jet Wood Lathe Duplicator Professional Duplicators WillAfter fifty of them even the top professional duplicators will no longer be your match. A decent lathe and a few decent tools to get you started and then do a little reading on spindle turning before you start. Get back to the books when you have some stuff working but encounter some difficulties. Having several calipers preset to key diameters is also helpful or make a finger rod to set behind your lathe which has wooden fingers that revolve around the rod and you set them on top of the spindle. The fingers need to be rounded on the ends so that there is no corners to catch as they swing downward. The rod that the fingers are swinging from needs to be mounted accurately paralell to the centers on the lathe. ![]() Some use curtain rods or conduits for the rod, pipes and tubes of any sort that are straight will work. A different finger length is needed for each diameter required. Fine adjustments can be made by sanding the tips of the fingers down a bit for slightly larger diameters. In use you set the fingers slightly larger than your finished diameters to allow for paring cuts and sanding etc. I felt much better after watching it than I ever did just reading the insruction book that came with the sears.
