Squaring up the tool rest

Perhaps the wood block would work, Pete. The way I checked and fixed it was by noticing how the 90 degree jigs (the V block and the chisel jig) were not square to the wear plate when they were in the miter slot. The easiest tool to check this was a 1-2-3 setup block. I then checked the jigs themselves with a machinist’s square, and found them to be square (the reference surfaces were 90 degrees to the miter slot bars). That only left one possibility: the miter slot was not parallel to the wear plate. And the only adjustability for that would be the two bolts that connect the tool rest table to the index arm. So, I loosened those up (they were pretty tight), held the 1-2-3 block tight to both the wear plate and the V block while it was engaged in the miter slot, and retightened the two bolts. It all worked out fine. It feels like, on an otherwise fantastic tool such as this, Sorby should either make sure this was right before it left the factory, or include an adjustment protocol in the manual. But, that quibble aside, I am very happy with my new ProEdge. It promises to be an important addition to my shop.

Right; this is mainly an issue for those who need square edges on chisels and plane irons. Since the ProEdge is geared more for wood turners than other types of woodworkers, I can see it not being as high a priority for either the company or most users. But since these specific jigs (the V block and the chisel jig) are meant to create square edges, and the miter slot is meant to help in creating square edges, I figure having good information available for those who want to attain squareness is a good thing. Thanks, and I look forward to learning more from this forum. It has already been a great help in understanding a few things about the ProEdge.

Hi, new owner of PE since just before Christmas, so lots of questions. But to answer this post, I found the table slot which came with the machine was parallel to the platen's surface and also at 90 degrees to the side of the platen. The narrow table purchased as an extra was slightly adrift when using the outer edge as a reference - loosening the countersunk screws and retightening whilst holding in the required position worked OK.
I've spent more years than I care to admit in attempting to use the Tormek wet system, with varying degress of success. This has to be set up in the house to keep the amount of moisture in my garage/workshop to a mimimum!
The sharpening etc. jobs I need a machine for are :-
Woodworking chisels and plane irons. Twist drills. Centre punches. Metalworking lathe tools. Also simple linishing of metal (i.e. removing the rough edges of hacksawed steel, brass, aluminium.) Already have concluded that the PE with home-made fixtures to accept Tormek jigs/tables etc. (also the UE 12mm bar and table) will result in a far more versatile machine than trying to adapt the UE - that's the Axminster machine.) Will post later with pictures.

Sounds as though you corrected one error with another (i.e. your shim). The original poster solved the problem by loosening and re-tightening the two countersunk machine screws which secure the table to the adjustable angle side arm. Checking the squareness of the table to the platen I found quite difficult, as it's the table's jig slot which is  the reference point. I used tooling plate (ground flat steel strips) - one in the slot, the rest between the slot and the platen.
As I reported earlier, my standard (slotted) table which came with the machine, needed no adjustment. The narrower table available as an accessory has no slot/jig groove, so it's the outer edge,  used to support the jigs, which needs to be parallel to the platen. Mine needed a slight adjustment.

It's important that I get this right, as I am using the machine itself to make additional jigs - to sharpen twist drills, for example.

Pretty sure that most timber can't tell the difference between a 24° and a 25° cutting edge what is important is that the edge is the same as the last time you ground it, the discrepancy will only be an issue if you are using multiple sharpening systems. I will however reach out to Clive to see if there is any way to adjust it.

Hi Andi, Clive is back on Wednesday and will probably comment on here, but I have had an Email reply from Steve at Sorby, If you take the belt off the backing plate behind it is secured with 2 13mm "hexagon columns" (fancy bolts!) loosen them adjust to get your 90° accurate and re-tighten and the job should be sorted.
