Hi Dave, I am watching with interest, I know nothing about vacuum engines so its look and learn. It looks like it will be an interesting engine when you have it running.
A bit of feeler gauge stock might do????
Anyone know, where I can source 35mm dia graphite in the UK. At sensible cost? :scratch:
David D
Very nice. Good work.
Just as a thought if you ever need to do another is seamless pipe. I used some sch10 316L when making an exhaust manifold. It's a bit more expensive but has no seam to worry about.
Nice work David!
:thumbup:
Now, waiting for my pal Dave, who's a whiz with a bore grinder.
Verrrrry nice David!!
Quote "Normal lathework followed. Finally finishing the o/d between blocks......."
So you are just using the friction of the two plastic blocks to keep the head centred?
Any extra friction material used?
BTW what is the yellow plastic?
Will
Very nice work.
"O WOW" indeed :clap:
Its getting there Dave
:thumbup:

Nice work again, as usual David.
Perhaps you have discovered a technique for drying these little things out to prevent rust? I realise that you have gone with a graphite piston but the bore would benefit from some hot dry air I think.

That's a neat discovery that it runs on hot air, David. And the slide valve is very pretty work! :clap: :bow: :bow: There is no condensation problem with hot air. One could finish a run with a hot air blower and put it way dry, if rusting materials were still used.
Hi Marra, nice to see her coming on well
I find a large bushy flame the best and I try not to use meths as it has more water and the dye :(
Try to get some Shellac thinners also these fuels are hygroscopic so may contain more water if old
A carbon monoxide (CO) fueled flame would be best, and would produce no moisture at all since it contains no hydrogen.
But not too good a fuel for other reasons! :wack:
(you'd want complete combustion to CO2.....) :smart:
I cannot remember the names of them
Stuart
Well done young Fella ... :thumbup:
That really is a nice runner .. :med: much improved .
You may reward yourself with an extra Jaffa Cake ..
Dave
Nice, you must be chuffed with that marra
cheers
Gluten for punishment :loco:
:D
Nah marra Iv seen the light going all steamy :D
Sooo the big Q are you fitting her with balls
cheers
Great improvement David, more than double where you started. Beautiful engine, too. :clap: :clap: :beer:
As ever a cracking engine rebuild ,good to see your still bringing them back to life . :thumbup:
I will see about doing a few flywheels in cast iron for you ,as I will need something to practice on wile getting to grips with the cupola :dremel:
Rob
Great thread, keep up the good work.
Cheers Mick
Ah so that answers a question.
Very nice casting :thumbup:
[Nice going marra.Have you sussed out tuther leg??
cheers
frazer
It's great to follow along with each of your improvements, David!
I also like your first picture -- naturally, I think it would make a fine avatar..... :)
Ah so that answers a question.
Very nice casting :thumbup:

Looking great as always David , Its going to be a fine looking engine when done . :clap: :clap:
Rob
Very nice David :bow: :bow: :bow:. And it truly was a generous lump from Andrew! :thumbup: :thumbup: :clap:
Glad to see it used David. I stashed that away DECADES ago :lol:
I wondered when the graphite piston would appear. Very nice it looks too :clap: :clap: .
If memory serves me right the original bore was 1 5/16" (1.3125"). What size are we at now,David?
.....OZ.
Wow!! That's a cracker of a quacker .... :bow:
I like it lots ...... :clap: :clap: :clap: :clap:
Just what they should do ..
Dave
I'm pleased to report, the duck has flown! Normal popping has returned........ :thumbup:
Thanks for looking in!
