Vaporiser woes...

On new years day I pulled the Pacemaker outside with the newly cored radiator fitted, and ran her up to a nice running temperature for the first time. All good - happy days.

However, the exhaust manifold and vaporiser gaskets disintegrated during this and were blowing really badly, so I've had no choice but to take the exhaust assembly apart.

Oh dear.

Sheared studs I can cope with. Cracked mounts I can weld..... 

But someone has welded over all of the tube ends - both sides! Restoring this is a slow time job.

I do realise this is an utterly stupid question, but, does anyone know of a spare pacemaker vaporiser for sale that is looking for a tractor to be fitted to......?

I can hear you all laughing already.....

Cheers, Jon.

RE:Vaporiser woes...

Jon
      I know that these vaporisers are as rare as hens teeth so is it possible to mill the welds down to the tube plate so that you can identify the actual tube location and drill the tubes out?. It's not too difficult to expand new tubes in as I have done the same with my MH 20/30 but then the old tubes hadn't been welded in!. I make this suggestion as I can see that you are fairly well tackled up and knowledgeable to do this in house.
  The construction of the entire vaporiser setup certainly qualifies for the' tractor design faults' section!                                                                               
                                                                         Good Luck!

RE:Vaporiser woes...

Jon,

My local engineer, a very skilled man, has re-tubed several vaporisers for me to a superb standard.  here is obviously an engineers wayto doing it and I would have thought that if you could track down a good engineering workshop then they could do it for you.  He used a somewhat ticker grade of tube and for want of a better word furled tham over at the ends to make a good seal

Jon.
              I have seen work done by John Farnworth's 'tame' engineer and can thoroughly reccomend his work but you still have to clean your vapourisor up unless you can find a replacement from somewhere.
                                                        Good Luck!
                                                                             Jack.

RE:Vaporiser woes...

Thanks Gents, 

Yes I’ll definately sort this old vaporiser out in the long run, but as soon as I’ve got new studs made and fitted in the manifold I want to get the old girl running again to finish getting the core engine right. 

If I can’t track one down I’ll have to make do as is and run it on petrol only. 

Cheers Jon.

RE:Vaporiser woes...

Hope you are making progress Jon?

Here are some photographs of what can be achieved with reproduction castings available from Rosewood Machine in Ohio.  These superb quality castings come with no butterfly, shafts and levers in the elbow, the vaporiser is a solid casting with no heat tubes at all.
So the attached photo's are after all three castings have been through Billy's Western Massey Machine Shop. They look and work just like the originals.

Malcolm.

RE:Vaporiser woes...

Thanks John, Malcolm. 

Whilst a new vaporizer from Rosewood is in transit, just thinking about how to do this. 
It looks as if the tube ends have been rolled over and swaged to form a seal - is that right? Do you know how it was done? 

Brgds Jon.

RE:Vaporiser woes...

Jon,

I had quite a few vaporisers re-tubed for myself and Malcolm in recent years by my local precision engineer.  He has rare skills and makes his own jigs when necessary to do these sort of jobs.  Currently he is making me a brass carburettor float for my MH No. 2.  I can only suggest you seek out a precision engineering firm and they ought to be able to fix you up - but nothing is cheap!!!

Good luck
John

RE:Vaporiser woes...

Yeah I’ll be doing mine John, I can think of a few methods - was just curious as to how they were done originally or your contact. 

Cheers Jon.

RE:Vaporiser woes...

Jon, 

I should have perhaps mentioned that my engineer uses thicker grade pipe to make the tubes.  As I recall the original tubes are quite thin walled.

John
