Chainsaw Repair

Here are a series of Silvey Razur Sharp II Square Chain Grinder Pictures. The grinder is more related to the swing arm grinder than the Pro Sharp series. The Razur Sharp differs from the swing arm in that it has two separate chain holders. One on each side. You sharpen the right hand cutters on one side and then move the chain over to the other side to do the left hand cutters. The chain holders are mounted on a common slide mechanism fed by a single lever on the end of the machine. This grinder is commonly mounted on a tripod style stand. Actually, the grinder is light enough that it can be moved out of the way when not needed. This particular one is not mounted on a stand but is setting on a piece of slab wood on a big rock. It was moved out doors for the pictures.

Silvey Razur Sharp II Top View from the mounting end. Note the mounting hole at the bottom of the picture where the grinder assembly mounts on the stand. Also take note of the off-on switch mounted on the motor. Typically, the switch is pulled towards you when you are in the operator's position to make the grinding wheel turn in the proper direction to approach the cutter tooth you are sharpening from the outside. I this picture you can see the two grinding wheel dressers. There's one for the edge of the wheel that shapes the side of the chain cutter tooth and there's one for the top of the wheel that forms the top plate angle on the chain's cutter tooth.
