I've already made modifications to the center shaft... this weekend the new bearings should be here... I have a couple pieces of 7075 Aluminum that have been sitting around for a while, scrap pieces... I have enough to do 3 out of that... I also have black knurled anodized tubing that I'll be making some tools from. Those should look sweet and run silky smooth.
The current tool was made from parts and materials laying around... I had to order a few things... but thays to be expected as it was a prototype. The central shaft on the prototype I'm not a fan of... So I changed the design slightly... The cutters... i have a bunch of wydias... i actually fired up my tool and cutter grinder for the first time in over a year... so soon I'll be hot on making cutters that I can use on the push style tool.
Later I'll update/edit with the amount of $ I have invested into the prototype...
