Thank you Grumph, be careful what you wish for.
Same old, just 360 cylinders again, nothing fancy but this time perhaps useful.
Note the new furnace layout. The incoming blast from the burner was always hard on my thermal lining, usually had to repack an area inside after each melt. With this new setup the burner blast it taken by the bricks, much more robust system.
I wonder if Blue Stuff IS Vinamold. You're supposed to heat it to 100 degrees to soften it enough to take impressions, maybe if you heat it to 170 it would be pourable. Conversely, Vinamold heated in boiling water may behave the same as Blue Stuff? I have some red Vinamold but can't get at it for the moment.
We'll soon see, I've taken the brave step of ordering some, dunno if it'll be of any use in the foundry but got to give it a try - my feeling is that it isn't as resilient (rubbery) as Vinamold. so may not be good to remove from awkward cavities such as transfer ports/passages - might still be of interest to the grandkids though!
Yes! that's the one for me - #0! (with batteries, solar panels and of course an electric motor) ie when they finally take my car licence away - then I can have an electric blanket as well! - clean and green........ beat that Flettner!
AFTERTHOUGHT - Maybe a Dustbin fairing as well!
Strokers Galore!
360 cylinders are away being heat treated at the moment.
New 125 RV crank case near complesion will accept all these cylinders and some still on the pattern bench.
Also will accept the epicylic crank.
I've scoped out how the tooling works, might have some spare ones soon. Need to make up a molding box to contain it all but apart from that I'll have a hack at casting one next melt.
I'd like to get these cases cast too but there is still some work to do on them.
Well. at least it's not a direct copy, LOL...More "school of Aprilia" Husa's moulds I assume.
Looking at the finished cylinder, and particularly the small ridges on the inside of the water jacket, can anyone come up with a reason for them ?
Is it just an artistic flourish on the part of the patternmaker or is there a purpose to them ?
