I suppose a fair few "budget" engines could benefit from it then, with the process making up for a lower overall build quality in general.
I have noticed that lower end RC engines do tend to recommend a longer break in cycle than higher spec models, meaning they probably do have to make up for worse original factory fitted spec parts.
I think I may be pulling apart the next RC Nitro engine I buy, just to see just how close the factory tolerance is.
I think I may even pass on the specs of that lapping tool of yours to an engineering friend of mine, could be handy to have something like that around to experiment with.
You don't need engineering friend, just bring pics to any machine shop and they will make it for you. I realy don't know how much they will charge for it, but it is worse it.
I sugest to use lapping compaund 1500 grid, never use diamond base compaund, use silicon carbide oil based.
