It looks very good, I like the engine. It may look bit rough now for someone's eye, but I know that since I've been working with same methods and I've built one Tube Frame and rear frame from brass. Once primered, everything looks so smooth and much nicer. I can't wait to see for more.

Thats a great Idea!!!

You probably will not want to have cured, expanding foam meeting liquid mold rubber. The rubber will seep into the foam's pores and at the very least, your molds will be heavily damaged when you attempt to remove the parts. Think about the foam and rubber meeting (and bonding) in every depression, cylinder bore, water jacket, etc.

Do you plan to make the second engine out of brass, too? I don't envy all the sanding and polishing you'll need to do to make the parts smooth enough to cast, especially in between and around the runners on the tunnel ram. You might also consider making the tunnel ram as two pieces instead of one so it's easier to cast.

Is there a specific reason you used tubing instead of rod stock to make the crank journals?

.Thanks for the insight on the casting , I will take it all into consideration. Im no longer making a second motor. And the sanding and polishing is the easy part when you have the right tools. The reason I used tube instead of rod is because tube heats faster than solid rod does therefore I can solder a part on faster and not have to worry about over heating or heat spread and other parts comming apart.

whether you guys know it or not. the cranks in these motors have hollow rod rournals and hollow mains. so the piece you modelled, romell, is actually quite accurate.

Ah, that makes sense.

Are you no longer planning to make copies of the engine?

Yes, it is, but just to clarify, my comment was made in regards to Romell planning to cast copies of the engine parts, as those hollow passages would be very difficult to pull off with traditional rubber molds. If he's no longer doing that, nevermind...

Yes i'm going to make copies but the man handling the molds for me will deal with filling the parts so now I don't have to make two separate masters.

the cranks are hollow because its all about weight and less rotating mass I am guessing, and tubing is stronger than a soild rod in most cases, great work Rom!

Hey fellas im back on this one and should have pics by tomarrow. Had lots of oxidation that needed to be cleaned up because I didn't prime the parts but a quick soak in white vinegar fixed that. see ya tomarrow.
