BlownCorona 3,996 Report post Posted September 17 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 Quote Share this post Link to post Share on other sites

Banana for scale. Also mm for scale. Its about 1020mm long. About 700mm tall 6 2 Quote Share this post Link to post Share on other sites
Not-a-number 2,254 Report post Posted September 29 The mandrel is spaced apart like that so that if we cant form it by hand and need to make hydraulic tooling theres some room to put it behind the rail. Ideally it would only be 100mm apart. Save some weight! 2 Quote Share this post Link to post Share on other sites

anglia4 1,634 Report post Posted September 29 what thickness is the chassis that you have to form over it? Quote Share this post Link to post Share on other sites
Not-a-number 2,254 Report post Posted September 29 32 minutes ago, anglia4 said: what thickness is the chassis that you have to form over it? 4mm mild steel. Though they did them out of G350 by accident. So that may or may not suck. Hopefully they can replace them with mildsteel. Quote Share this post Link to post Share on other sites
anglia4 1,634 Report post Posted September 29 I guess its a good thing if you are able to form it Quote Share this post Link to post Share on other sites

anglia4 1,634 Report post Posted September 29 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? 1 Quote Share this post Link to post Share on other sites

Ive heard if it was G350 that would probably crack and distort it. Since it would be locally annealing. Quote Share this post Link to post Share on other sites

IvyMike 277 Report post Posted October 15 What resin do you use for your castings and at what ratios? The quality looks great. Quote Share this post Link to post Share on other sites

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. 1 1 Quote Share this post Link to post Share on other sites
