Well I was curious to see if the castings were any good. I was seeing some pits in the surface of the pieces and that made me a little nervous. I setup the oil pan casting and made some surface cuts. They looked pretty good so I surfaced the top of the casting down to size. The pocket for the crankshaft clearance was completed and all the holes were drilled and tapped if needed. The holes to mount the pan to the block are counter bored so mounting hardware will be flush and hidden when displayed. The pan will need to be bolted to the block to proceed any further.
Just in case anybody was wondering, the pan was held in the vise with about a half inch of vise jaw showing on the right side. Center "Y" was found using an edge finder between the jaws. The casting was then re-positioned center of the vise. With the flashing filed off, center X was found by centering on the casting. Y needs to be kept tight but X is not too critical. Because the mounting flanges need to be .200 thick when finished, I setup the oil pan onto a pair of 1/2 inch lathe tool blanks between the bottom of the flanges and the vise jaws. Then just touched off the blank to set the Z axis at -.200. If further information is needed email me and i can send over some 8X10 color glossy pictures with circles and arrows and a paragraph on the back of each one explaining what each one is too me used as evidence against me. I'd post them here but my photo bucket is 97% full and I have a ways to go in the thread.
The part about the 8x10 glossy pictures reminds me of the song by Arlo Guthry "Alice's Restaurant" back in the seventies is this by any chance intentional? Beautiful work I'm really enjoying the post.
