These completely cut out frame assemblies are made out of 1/2 inch high strength aluminum. The hard work is done for you! With minimal machining these frames are ready to be made into nice radius tools! Up to 2 inch balls can be turned, (depending on model). Will fit any 1/2 inch OR 3/8 inch tool holder, (depending on model). Model RT-2 has a 1/2 inch shank and model RT-.375 has a 3/8 inch shank. If you have a drill press or mill with a vise, (or your lathe with a milling vise attachment) you can make one very easily!
Now available, RT-2b, a "pre-broached" model! This model has a square hole broached to fit most 1/4 inch square toolbits! Why try to file a precise square hole to fit your 1/4 inch square toolbits?
RT-1(no longer available) / RT-.375 EACH ONLY $28.99!
RT-2 $36.99/RT-2b "pre-broached" $45.99 (to fit most 1/4 inch square tool bits) On occasion we have a 2", convex/concave model available for $64.99, (#RT-2CC). See metalworking -"purchase" pages.
A small parts kit for our 2" radius tool frame is now available, (see purchase page). A "convenience kit" that many have asked us to supply of all the little parts, (berings, rod, set screws etc.), needed to finish the 2" radius tool.
See the second picture of a completed tool. Item is for frame assembly only, NOT A FINISHED TOOL!
Why pay up to $150.00 to own one when you can NOW make one easily in about 1 hour? You will need, (for model RT-1)RT.375 / RT-2 will be similar);
