    Bought some fibre abrasive wheels on eBay, ... I really like it so far for removing tool marks on aluminum and deburring.

    What hardness (5P, 7P, 9P) are the wheels? How much do they deflect/distort in use?

    • Matched pair of V-blocks for holding parts to machine 45 degree angles on. I have lots of occasions that I need to grind 45's on the edges of parts, especially parts with a heel on them, that I can' t just dress an angle on the wheel or set up in some other conventional way. This act as V_blocks and the clamps are basically toe clamps. There is a removable back stop for referencing parts.

      • Pretty skookum pair of V-blocks! 👍

        • Those V blocks look great! Good job

          • I like the V blocks too! I like that they have a way to grip the work built in.

            • not much of a tool, but I had to make it to complete my nutcracker project - an 80deg press die for my hydraulic press to bend the 1/4" steel legs on the cracker.

              had to use a bunch of C-clamps to stop my adjustable lower bending jig from spreading (see broken bolt above) - the forces involved were quite a bit more than what I'm used to!

              • AXA tool holder for 3/8 HSS bits, angled 15 deg in 2 axis. Now you don't need to grind on the top of the tool bit. It should offer some advantage in not lower the cutting edge height from repeated sharpenings to the point that you grind the
                end of the tool bit off and start over.

                • This looks somehow familiar...

                  I'm about to design and make my own AXA holder for the same geometry as my early test version. But I'm going to set the slot a little higher and make the top view a wedge shape so the front edge sits just past parallel to the post body. That way I don't have to angle the post for facing cuts and I can use a longer tool bar. the body will sit slightly low or be a touch deeper.

                  The tool holder got put onto the computer desk just yesterday and the CAD'ing will be done a bit later today.

                  • Very small bit of metal under the tool bit. I have seen that lower part snap off under load.

                      Sorry Bob, missed this comment. I think the grey one is a 9P. The other is scotchbrite so it kind of does whatever it wants. The grey one doesn't seem to deflect at all, but it wears a rut quickly if you're not careful.
