Today I cut away some of the guard on the Aldi 125mm angle grinderto make it more useable - half the face was covered in so fine for cutting discs, but not much use for flap wheels, brushes, etc.
To do this I used the 115mm grinder, that has a faulty switch so is difficult to switch off, and has tooo small a guard to take 125mm flap wheels, discs, etc.
Finally managed to use a flap wheel on a grinder to do the coarse work on my axes (small hatchet that had some nicks, new maul that had a 'cutting' edge a few mm thick, and my felling axe while I had the rest out.
