Graver Sharpening Fixture

thingiverse

This is a graver sharpening fixture I've designed, I've made it similar to the commercially available ones. Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator 2 Rafts: Doesn't Matter Supports: Yes Resolution: 0.15 Infill: 50 Post-Printing Dial front A and 3mm square graver clamp 8th Feb 2017 Front Dial and Graver Clamp. Both prints came out well and I'm pleased that the lines for the 5 degree increments also printed nicely. The threaded brass inserts and 20mm M4 bolts fit well on these parts and it holds the tool steel securely, One issue is that if the holding screw on the graver clamp is over tightened it can split plastic. I've edited the model now to have thicker walls at this place. Frame B 13th Feb 2017 First part of the frame printed well (tho my print lifted from the bed slightly), this part fits together well with the dial front and the 30mm M4 bolts and threaded inserts. Tightening the screw holds the dial in the desired position. Dial Back B 15th February 2017 Finished Prints 3rd March 2017 The first part of my frame came put bowed so i want to reprint at some point, but the design works. I have an old dermal drill stand which I'm using as a base, its post is 16 mm in diameter but I'll upload the 123d design file so any one can edit this part to suit there own needs. I've created 2 gravers using this so far but clamping it to my drill press and using diamond lapidary discs on an arbor. Additional Items needed I've designed this to use M4 Bolts and 8mm x 5,8mm Embedded Nuts. M4 x 8m Female Thread Brass Knurled Threaded Round Insert Embedded Nuts: http://www.ebay.co.uk/itm/302019218254?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT M4 Bolts 20mm and 30mmhttp://www.ebay.co.uk/itm/221307549544?_trksid=p2057872.m2749.l2649&var=520187426970&ssPageName=STRK%3AMEBIDX%3AIT
