I put a couple coats of primer on the pattern but I needed to try and mold it before I go any further incase there is not enough draft in the part, if there is not enough draft the part will not pull from sand.

We had a good pull now I can get a few coats of paint on and wet sanding this will take a few days as cold as it is for the paint to dry in between coats, the pattern when done will need to be shiny and perfectly smooth so it pulls easy and the petrobond sand mix I use will show every detail, I can pull a fingerprint with that stuff.

This is the first coat of paint, I will have wet sand and repeat till part is perfect the edges of the wood really soak up the first few coats. When the part is finished I think I am going to mount my coils in this location

Made the actual first part from this pattern, came out good for a first pour I think I will hit it a little harder next time to have more head pressure but a nice first part.

As cast





Flashing removed and drilled

Originally I was going to cut the center out but after a discussion on it decided to leave it as is, the part is solid enough for mounting a oil filter adaptor coil etc.

A few shots mounted not sure the finish I will put on them yet, they will clear valve covers without spacers also fits rear mount OE oil coolers, this is just belt sanded and edged I will throw it in the vibratory for about a hour.

The tops are taped for 10-32 so the MSD vibration mounts just thread in.

few more

Just read your thread CPM, you do really nice work. The white hull is 100% better too!! Look forward to seeing your progress.

Last night I was casting some parts and on my bench was one of the plastic clam shell covers off the back of my boat I decided for fun to pounce one out and see how it would mold and pour, this is by no means a useful part but just testing the waters with it and after looking at it I think I will clean up a plastic one and turn it into a pattern and make a few. It would fit the factory holes and look a lot better
