shit that's going to be a large motor!

i had in my head that those parts were the profile of the crankcase and that part housed the crank gear like a standard engine would have a timing gear case on the front of the block

Yeah its pretty big.

Banana for scale.

Whats wrong with using 350 as opposed to 250?

Nothing, just that it will be harder to do by hand.

Its higher tensile material. Nominally 350MPa yield strength as opposed to 250MPa.

To form it over the mandrel you need to be able to "yield" it, so the higher tensile would need more force to bend to yield.

@Not-a-number will you be heating it to form?

Hopefully not but probably. Ive heard if it was G350 that would  probably crack and distort it. Since it would be locally annealing.

What resin do you use for your castings and at what ratios? The quality looks great.

Techniset 6435 with catalyst 712. Its a 3 Part system.

Part 1 + 2 = 1.8% of sand mass

P3 = 3% of Part 1.

Sand is #90 so quite fine.

3 part system works way better than the 2 part I used in NZ. Mixes really evenly with hardly any effort.

Super cool! Can you reuse the sand after is has been used with the resin in it? can you give an example of the sand recycling process? #thumbsup
