Support wedge for grinding scrapers on the Sorby Pro Edge

A woodturning scraper works by the virtue of a burr on the cutting edge. On a normal workbench grinder you can simply place the toolrest a bit lower to achieve an angle greater than 90 degrees and grind your tool ‘upside down’. The Sorby Pro Edge is a belt grinder with flat grinding surface and the toolrest can only be raised to 90 degrees. If you grind your scrapers with the 80 degrees inclination, there will be a burr, but it will be on the lower side of your scraper and not do anything. 

This item adds an extra 10 degrees of inclination to the toolrest. Also, being plastic rather than steel, it does not ruin the burr on a round nose scraper. If you are concerned about the burr damaging your wedge simply use a small sheet of cardboard between the wedge and the scraper. 

The bottom of the wedge features a ridge that fits into the slot in the ProEdge toolrest and two holes for 12 mm magnets. The top plate features, again, a slot like on the original toolrest so you can use any of the guides you could use on the normal toolrest. The slot on the wedge is set back a little to keep the guides away from the belt. 

Printing was upside down so the toolrest surface of the wedge is on the build plate so it becomes as flat as it can be, and there is minimal need for supports.  

I printed on an MK4 from Fiberlogy ASA, but probably PETG or PLA would have been easier for this shape. The shrinkage of the ASA when building the wedge bottom (printed upside down. remember) caused so much warping I had to make slots in the bottom to break it's strength and contractile force. 

Printing parameters: layer height 0.15 mm, brim and support to baseplate.  Exruder and bed settings as per Prusa recommendations for Fiberlogy ASA.
