Zero clearance side seals round 2. (If you don't mind Barry)

[Slides]

I genuinely though Ted forgot the italics in his comment here until I saw it was actually closed. Not sure why you wouldn't want documentation of long term runner that someone has tested in one place? (I will say mods/admin on other forums encourage keeping tech stuff in one place)

So, seems this is a goer.



I would like to do this when I eventually get around to building one or other of my engines, the 12a will have to come apart for clearance/lighten/balance anyway as there was still vibes with what was sold to me as the correct series auto counterweight (will do the measuring check etc again but I want to port it anyway, will send to spinny bits to Freaky or Wilkins to machine) with after-market flywheel and there was an issue with leaking intake crossover o-rings/gasket filling housing with coolant too so I'm guessing it could be a bit messy inside.

If you don't mind me asking Barry do you cut them with a fine diamond disk with a dremel style thing or is it more like a milling bit. I guess I'm curious as to whether there is a tight or open radius under the side seal and how hard it would be for me to replicate it, given sending you seals/rotor from Aus would be cost prohibitive and I'd like to try it myself anyway. Is there enough length in generic side seals to do this effectively?
