Ok ,hey it was early ;D 4 big 4 small . If it's ok with everyone else let's do it. Dick

Would there be an advantage for those of us doing the bearings to do pairs (2 big +2 small) so that we get a matched set? Thoughts please. Dick

Bob the fixture looks great! Also .125 radii everywhere is good with me. I have a drawing done of my block and I'll post it tonight. Will we thicken the top strap to accommodate the oil cups ? Dick

I haven't ever used the MIC6 grade aluminum. A quick search told me it is precision ground +/- .005 cast aluminum plate. Besides the ground finish to start does it have any other qualities that make it a better choice then 6061 plate? I have no problem with getting some if it will fit better...

This will be my first IC. That said I will be happy with something like the Webster. If the confidence level of success is that high amongst those that have several under their belt then let's have at it. ;D Dick

Good morning, Looks like bearings for me. I don't have a preference so either is fine, but sign me up for one the suspense is killing me. ;D PM the address to send each lot of brass and I'll get them out . Thanks Dick

I agree ,I would leave the bearing where it is so we don't have extra holes in the base. Flywheel size won't change. Location would be up to the assembler. :D We would need to add the collar though in the event the flywheel is used outside the bearing. Dick

Sign me up if there is room I'd like to be part of it! Dick

Yes Eric , that is why I said we need a collar if we move the flywheel outside the bearing. Without it the forks will rub on the cam ring and cause excessive drag for sure as well as the cylinder floating out of it's valve alignment. We could still get a tapped hole in the hub with the flywheel...

On the small end bearing we could use a flanged oilite bushing to carry the thrust and load better. I expect it's light but less drag is better right ? Dick

Thicker base sounds good. Regarding the flywheel ,if we move it outside we could extend the hub slightly for a set screw to eliminate the threaded hole in the rim. Might need to extend the shaft slightly as well. We will also need a collar to keep the load off the forks and cam. Has anyone ever...

Ok, I checked and I have 2" Brass for 16 flywheels I'll donate to the build if that's the way we go. It's made up of end cuts but the OD isn't marred up much. Dick

I'd like either Bearing blocks or Flywheels, your choice. ;D I have 6061 for the bearings blocks and I might have enough yellow brass for the flywheels but I need to check that out. Thanks, Dick

Waiting patiently ! ;D Dick

OK I just want to stay involved now that I'm in. ;D I read this entire thread and the Combers sounds great. I'll go with doubling and if the consensus is for both that is fine too. When do we start? Who going to distribute the parts/prints to the participants? When done do we ship one to each...

Good morning, I'd like to get in on the build if there is still room. I'm new here but I have some experience in model building (simple ones) :) . I have a lathe and a mill. Dick
