I ain't no engine whisperer, but I have two potentials from my Corvair days: 1) They put forged pistons in bores sized for standard cast pistons. Forged pistons expand a good deal more. Piston to wall clearance is a super important spec in air cooled land, not sure on your Fjord. Also not sure if your pistons are forged, they could have just left too little clearance anyway. 2) You definitely have arrows on your pistons, indicating offset piston pins. Were the arrows all pointing the same way, and was it the correct way? Edit) 3) Of course it could have just overheated, duh. How's the water pump/etc? Got a good straight edge to check for a warped deck/heads? Commodore_64 fucked around with this message at 19:03 on Mar 11, 2024 |

I would strongly recommend taking high res video, decimating it, and running it through meshroom on a PC. You get a lot of similar issues, just the quality is much better.

Also, IIRC, shell bearings crush into the bore by virtue of being slightly taller than the caps / effectively a greater circumference. Not sure on the range on that, but it probably could be used to rationalize away small differences.

There's a fancy version of that with talc and acetone in a rattle can, but its way too much $$$. I think it's used as the "developer" for dye penetrant testing, but it gets a lot of use in 3d scanning. It does help with gloss and pockets/pits, but you might need to add a few reference marks with a paint pen or marker.

Just curious, how much would that part weigh in aluminum?

Dr Rocksalt posted:Probably a lot, or “too much,” but compared to this blower weighing so drat much, yolo? Sorry to be coy / not explain fully. I was just wondering if it could be cast from the standard crucible a hobbyist electric furnace. Something like https://www.amazon.com/TOAUTO-Upgra...142&sr=8-2&th=1 They claim to do .9kg of aluminum in a crucible, so maybe .8 or so in reality. I was thinking you could do a lost pla casting in plaster or green sand. I've been really interested in trying this lately so I was curious.
