Did Winny not have something to do with sending the army to sort the Welsh miner out even shot a couple. Dam strikers Maggy the milk snatcher must have taken lessons from him
No gentleman he gave his parole and broke it I believe or is that yet another myth .
Another good little book High Speed...
Congratulations on a fine engine
We all make mistakes its what makes the hobby fun or so I tell myself. If youve never mucked anything up then youve never done anything my old man used to say
Keep well
Should have also said. An increased crankcase pressure will increase engine power as would using a better heat conducting gas. Then it would have to be sealed and again frictional forces would increase.
On a small coffee table toy like this it would all become pie in the sky its just a toy too...
Hi K2, hmm how to answer
Agreed a lip seal may be a better alternative but does the friction not increase as the pressure increases. Also Im a tight wads and like to make everything I can
The air passage way is lined to reduce heat loss . I had some machinable ceramic in my swag stash from the...
Hi Jim, its all magic n mirrors :}
The engine uses the Ringbom principal but due to the rotating cylinder becomes a marginal thing at best. The passage way for the hot air is a bit long and convoluted and the pivot is an air leak point. It was nearly a runner for ages just no cigar until I...
Hi, after nigh on two years of mucking about with this wee engine finally a runner
Just shows what lockdown boredom can bring about I guess
Cheers and thanks for looking in
A bit of bedtime reading ?

Noggin end sell graphite in the UK
P.O.M is also hydroscopic and if you should happen to get it too hot it gives of formaldehyde gas. Delrin is a brand name as is Hostaform and a few others I forget.
One of the benefits using graphite for hot air engines is its low rate of expansion and self...
Not one to post builds anymore but will do a wee thread when I make the next batch. Very easy and no faffing snapping those drills and 0.3 is an easily obtained size
When making small gas jets. I drill 0.3mm then swage down to the size needed. It saves snapping those drill bits
It is just a simple jig , punch and guide to keep the hole middle for diddle. The wire is easily found
I also tend to make batches of 10 and need to make some more shortly
cheers
Jon, youre right and were would be the fun in buying one
Screw cut a couple of adaptors today so just need the figure out the rest of it
I tend to use iso metric now as this side of the pond they are much cheaper than imperial. Although I often use an imperial size just to nark the crap out of a...
The pitch is different to UNC or UNF at 27tpi ? or am I looking at this wrong
26tpi will go on for three complete turns ,this is what I had thought it was as its nigh on impossible to get thread gauges in and be able to see
Found it so the S is for special ? and I thought the UK had some odd...
Depending on the size of the bore ? . Use a centre in the tailstock to push the Keats against the faceplate with the casting already fixed into the Keats .This should get you to within a couple of thou
If the bore is larger than the centre turn up a button or top hat bit of scrap the smaller...
