Ok I finished off the tappet bushings.    and I started checking the block.   From the centerline of the crank to the seating surface of the tappet bushings should be 1.625.  It's currently 2.060   :o   So some stock needs to come off of that.   I'll double and triple check that one!!!

I also need to drill and tap the dip stick/breather hole, and bring the deck height in to final size or 3.3125, as it's about 0.005" oversize currently.

So I need to make a fixture plate, and that will allow me to hang this part on an angle and right on the mill table.

Additionally, I finished making the lap for the cylinder liners.   

We progress!......

Sorted out the tappet bushing height issue, and will make tappets next...but after I finish lap the bores, and finish the pistons and rings.

It's coming along...I got 3 1/2 hours out there today.   

tired....but it's longer than I've been in there in a while....

PS    If you build this engine, it calls for a 7/16 across the flats on the tappet bushings.   If you make them that size, you can't get a wrench on them.   I made them 3/8 across the flats....much better.

Its' nice to be healthy enough to do something again....though I can't do it as long as I used to thats for sure.     3 1/2 hours yesterday.    I used to be able to do it for 14.....

Ah well, none of us are getting any younger.

Here are the tappet bushings installed   I made them longer to better seal the tappets, and I made the hexes 3/8 instead of 7/16"    they are on 1/2 inch centers so no way to get a wrench in there

Yep that shows the tightness you mentioned earlier. The smaller hex size shouldn't matter at all. Looking nice though!!!

I wouldn't care about the size being smaller as they look (fantastic) like they are a perfect fit and elegant too  :ThumbsUp:

Thanks Admiral,

Ok started the lapping.    The goemetry and finish is good, one cylinder is about 0.0006" bigger than the other.   I dont think thats a big deal....im not making 100 of them.    A little more.and leave it be.

Nice work Steamer! Bet there are a few guys out there wishing they reduced the size of the tappet bushings. Good call.
