I was able to use the Pro Edge for sharpening wood turning gouges but am having difficulty in squaring plane iron.
The V-Block is 90 degrees to the back plate when the table is at 90 degrees to the back plate.
However, when I sharpen at 30 and 25 degrees using the V-Block, one side is not sharpening at the same rate. I am confident that I am using light and even pressure across the plane iron.
I had bought the PESQW adjustable square guide as the PESQ was out of stock. By setting this at an angle which is less than 90 degrees, the plane iron sharpens square.
Installing the belts shows that the tracking is correct on the top pulley but extends 3mm to the right at the bottom.
Please advise whether the belt tracking may be causing the problem, it is a new user error or whether there is another adjustment I need to make.
Many thanks in advance for any assistance.

See My Thread for the issues and problems I've had with my ProEdge. Firstly not all belts run true, the ceramic ones in particular are thicker and seem to run less smoothly, use the aluminium oxide belts only for plane iron as they seem to tension better and run more smoothly. Despite what the official Sorby Response said I found adding a tiny amount of extra tension on the belt improved many of the issues I had but not eliminated. I have now inserted a 2mm washer under the spring which has fractionally increased the tension and improved matters. The belts also improve with age as they seem to bed in with use. I've come to the conclusion that the device is not good for plane irons, use it to rough out the primary bevel and then go back to diamond stones. It's fantastic for turning tools but a disappointment for anything wide and flat. When I can get to a show I will see if I can get Sorby to demo sharpening a plane iron and confirming the bevel accuracy on a diamond stone before I'm convinced....Perhaps they could do a video to show this.... |

Rich, many thanks for the quick response. I had read your thread and just reread it. I noted the issues and problems and tried to see whether these were the same as mine and came to the conclusion, possibly wrongly, that my problem was not quite the same.
I’ve currently only got the 60, 120 and 240 aluminium oxide belts which I understand are better for plane iron and chisels. Setting the PESQW square slightly off 90 degrees seemed to provide a solution but this does not seem to be a good approach as it is easy to knock the setting off and I would have to reset by trial and error.
It seems strange that the belt does not align perfectly between the pulleys with the bottom one jutting out by 3mm. As it is this side of the plane iron which is not square I wondered whether the belt sort of flaps causing more steel to be removed. I will add the washer as you suggest and see if this corrects the error.
I’ve checked for squareness when the V-Block is at 90 degrees to the table and backplate but wonder whether when moving the table to 30 and 25 degrees whether this is not at 90 degrees. I will check by using a gauge to see if the back of the table is further away on the right hand side of the backplate when it is in this position.
As it took me a long time to get the plane iron close to 90 degrees I am a bit hesitant starting another or using it for chisels until I have identified the problem(s) for sure.
I would welcome any other suggestions.

I've just checked my ProEdge and with the belt aligned to the right edge of the table as suggested in the manual then the belt is flush with the top pulley left hand side but is shifted over by 5mm on the bottom pulley so you can see 5mm of aluminium pulley on the left.

I don't use the ProEdge for plane blades but do use it for the main bevel on bench chisels never below 240 grit unless I have a serious accident with them, then I use a micro-bevel and sharpen manually. This guide may or may not help www.youtube.com/watch?v=bBJm2Y-laJ8 |
