Gerhard Gerber Posted January 25 Share Posted January 25 I've had issues with my one grinder for a while, failed bearing in the one wheel of the platten I think. Built a new platten but I was greedy, made it too long so on the standard mounting points the track is too long for a standard belt. During one of the attempts to get things to fit we stuffed up a bearing on one of the new contact wheels, time and hassle (need a press) to fix that made me shelve the project. Few months ago I was doing last bit of grinding on a blade when I felt something was off, assumed it was the belt, turns out its a tear in the poly-whatever coating of the contact wheel. Since then I'm only able to use belts with a thick backing, so I'm limited to 36grit, sanding from there. Fixable, but finding the time to have it machined and the risk something goes wrong on the lathe has me holding back. Justifications done A friend bought a grinder while on holiday in South Africa, one of the new breed with the work rest below the wheel. I'd seen videos, but seeing it in action put me over the edge. Contacted the guy, busy arranging transport, and I should have it in a few weeks. Two biggest wins are I'm getting a small wheel attachment, and it can be used as an improvised surface grinder. My friend has only ever used his wonky home-built grinder, he's now churning out blades with the most perfect swooping plunges I've ever seen, watching him it's easy to see how. Same friend also visited another maker, and apparently he has one VFD he uses for all his grinders, one at a time of course. I assume all you need is a 4 channel rotary switch? Please excuse my utter ignorance of the correct terminology. Anybody else doing this, is my assumption correct, and what do I ask for at the electricky shop?
