If it works it's not a bodge ..................... well that's one way of looking at it ............. I'd go with the loctite personally, it's fairly easy to warm up and break the seal if you ever need to take it apart in the future.

Tim,

If you fit bearings, you should not have anti friction flanges on the blocks, but on the component parts that are in contact with the bearings, crank discs, eccentrics. They need to be the same diameter as the ball race inner race, and only need to be a couple of thou thick, that is to prevent the component rubbing against both the inner and outer races. Sometimes, the inner race is minutely longer than the outer race for just such a situation, but not always. So you will have to measure them to see if the inner is protruding slightly. If it is, you should be able to get away with not having to cut the friction flanges on the parts.
I hope I haven't confused you even more.

No, that has cleared things up nicely, thank you :thumbup:
I have already cut the flanges on the bearing blocks, but only on the faces that would not normally be seen when all's assembled, so I dont think it will make much difference. I didnt know about making the flange/boss on the other componant faces, but I have made a mental note to do that when making the eccentrics and crank discs. ( assuming that the inner race is not protruding )
Thanks again guys for your help, this place rocks :nrocks: :mmr: :nrocks:

To clarify my earlier post, the right eccentric is outside the bearing, not the left (flywheel side).

You are right indeed, I've just looked a little closer on the plans and see that as you say the right eccentric is outside of the bearing block. I'll have to turn a boss on that bearing block as I dont have a ball race on the outside of that bearing block.
Thanks Kvom for that :thumbup:
