Great thread... I too have this on my to do list. I had a cnc 5 axis in mind or a manual horizontal deal...

Nice fixturing there sherminator2 ! What max angle can you get out of it ? This is what machining is all about.. the creative routes!

Does anyone know the common angle of the splayed holes ?


Thanks
Kris.

I did not intend to get a large angle. Just enough to square the engine block to the table. I was thinking of nodding the head of the mill to do the splayed bolts.

This does bring up an interesting thing though. The block is inherently unstable on this fixture until it is bolted to the table. Visualize the center of rotation below the table and the center of mass way above it. The block will literally try to roll right off of the table.

BE VERY VERY CAREFUL! Keep the block hanging on an engine hoist until it is well secured to the table.

I just measured the Milodon caps that I have and the bolts are canted 18°.

What I did on mine is to weld 6AN fitting then use a braided line then cut it to length for the dipstick to read correctly. This way its flexible enough then when ur done, just cap it with a 6AN plug. Incase ur running a vacuum pump.

I have the new dowels installed and they fit very nice now. I have layed out the thrust 'step' dimensions. I will do a rough cut and re-install and make sure measurements are lining up before finish cut.

For drilling the 18° holes, how deep until the water jacket becomes close?
