Bob,
I started taking Wal-itin by my doctors recomendation it's Walgreen's generic version. Other wise I'd be blowing my nose all summer, oh yeah and sneezing to.

Block continued-

The cam tunnel calls for a .312 diameter hole, 4.523 deep.  In order to get good geometry, the engine block was setup on an angle plate on the faceplate of the Rivett.  A toolmaker's button was used to locate the center point of the block.  As of right now, I am about halfway through the block with a .250 pilot hole.  It is taking an extremely long time to drill the pilot because the lathe is in backgear and the surface speed is far below what a .250 drill requires.

Thanks Bill.  My allergies were bad Friday and Saturday.  They were good yesterday.  I should have quit while I was ahead though.  I had a little mishap with the block. The boring bar rubbed and the block shifted on the angle plate.  I believe it is recoverable.  I just have to add an extra step to the plan that I had in mind.

Hi Bob

 Just caught up on this build. Excellent work so far. I'll be following along. Did George have a build thread on this engine? I need a project for this winter, and this looks like a good one. So I need plans.

HI Garry,
There is no build thread as it was made long before I had a computer or digital camera. I do have the drawings. Send me a personal email and I'll give you the particulars.

Thanks for following along Gary.

It will be nice if you pursue this engine also.  If we can get a third person (come on Bill), it will be the "Tiny" builds of a couple of years ago all over again.

Unfortunately, I couldn't squeeze in any shop time this weekend.
