I really want to try it on a grinder with the hydraulic clamp because it would be really quick to work through a chain. If you have a thermometer can you test to see how much heat builds up on the cutter when grinding? I'm surprised it barely changed at all with this.
I am thinking of getting one of these wheels soon. I will ask 2 questions. Question 1 The wheel from new is course has it worn smoother and gives a better finish now its been used a bit. Question 2. I am thinking getting 5mm wheel will do 3/8 and 404. 5mm is closer. To 4.7mm and that's what the pink wheels are 4.7mm wide. What's your view on it.
@@ChainsawUsers Still cuts the same as when it was new. I have not flipped it over because I wanted to see if it wore down to a smoother finish but, nope still the same. The 4mm has worked out pretty well. Some of the taller 3/8 chains are a bit awkward (EXL) when new, all the 404 has fit well so far. I have some spare links around if there's anything in particular you want to see let me know and ill run it through tomorrow
In my humble opinion the price does not justify the advantages of such a wheel, dubious as they are. This wheel, as I wrote before, is quite coarse-grained. Therefore, the finish will never be very impressive. Of course, the coarse grit means that the tooth temperature will not rise as rapidly as with finer grit wheels. But this also applies to "cheap" grinding wheels. I can buy a green Tecomec grinding wheel here for €7, which is coarse-grained. If I want an almost mirror-like finish I can have that "brown" grinding wheel for €5. That ABN/CBN doesn't require dressing isn't quite true either. The advantage of ABN/CBN is certainly a lot less nasty dust generated. Another advantage may be the certainty that it will not come apart at some point during grinding. Of course, in this case, there is also the matter of supporting the domestic manufacturer, which for me is not insignificant either.
I agree with you, the main reason I bought this was curiosity. The economics of it stack up differently here, Tecomec green wheels are $74, which is just insane, but I still could have could bought 3 of those for the price of this wheel. More likely I would have bought 6 boxes of Vallorbe 5.5mm files for the same price. The total cost of the grinder and wheel is the same as buying a Tecomec Jolly Evo here, that's how I justified it to myself. I really don't know if the rough surface finish on the cutter has a significant effect and don't really know how to prove or disprove it. I can test initial cutting speed against one with a smoother finish but suspect its biggest difference might be in durability and it is much harder to test because I can't completely control what they cut.
I may have to get one also

@@SawChainTheories The main thing is the wheel sharpens the chain and keeps a good edge
