Hi Folks.
I wonder how many of us have a Clarke, or similar, 3 in 1 sheet metal machine that has had so much use the guillotine blades are a bit blunt. I would guess, a lot!! I decided my blades were blunt and needed replacing, so I went onto their website and pulled up the relevant owners manual to see if the part numbers for new blades were shown. While I was looking through the manual, I found out that the blades fitted to all there machines, are double sided, and when the blades get blunt for the first time, it is only a case of unscrew the blades and reverse them on their screws fixings, and you have a machine that is as sharp as new. I took the movable cutting blade off and checked the used cutting edge. It was blunt nearest the right hand side, which is where most of the work is done because that is where the square guide is for cutting sheets square. Anyway, I felt along the fixed blade and that didn't seem too bad so I decided to just reverse the movable blade to see how it cut, and what adjustment I might need to do. I reversed the blade and found a piece of 0.5mm nickel silver sheet, that was 24" long x about 4 " wide. I set it up to guillotine a 1/2" wide strip of the whole length. The machine cut as well as the day I bought it, with no adjustment whatsoever!! That's it folks. Undo 6 capscrews and remove the blade and turn it over so that the edge that was doing the cutting, is now up in the mounting slot, and the unused edge is now the cutting edge. Replace the 6 screws and keep your fingers crossed that you won't need to do any adjustment. If you do have to adjust for the machine to cut uniformly, again, that is easy, though I didn't need to do it. When you look at the back of the machine, there is an assembly that looks like a very heavy duty strip of spring steel, in the middle of the blade. The screw can be adjusted to increase blade pressure at either end but not in the middle, or increase blade pressure in the middle but not at the ends, to even the cut up. For the adjustment, it is useful to refer to the instruction manual, because it has pictures and text.
