Hello All.

I’d like to share a little nostalgia with you. The following pictures are of a Robinson platform that my father in law and I moulded 10 years ago. It was one of the last Iron castings to leave the Buckley Iron foundry when they closed. The casting wasn’t a very good one, there was a nasty gash across the upper part and the “ air port “ core had broken and breached to the water jacket.

Sadly my father in law has since developed Alzheimer’s disease and as a kind of comfort Mathew decided to try and use his grandad’s handy work.

A big lathe makes the job look easy.

Cheers Graham.

As a follow up....

The gash in the platform quite literally, disappeared!

But the photograph shows the breach into the water jacket quite clearly.

We have milled down through the top with the intention of gluing a rectangle of Steel into the neat slot, pre drilled, of course.  ;) The beauty of this is that the cylinder sits and hides all the remedial work, only we and the entire readership of MEM will ever know.  :)

Jo.

Please note my special coating process is already starting!   ;)

Cheers Graham.

Some sad news.

Alan, Mathew’s grandad passed away this morning....

He took over Alyn Foundry for a few years whilst I recuperated from my own health issues, he will be sorely missed.

So sorry to hear your sad news Graham. Without Alan, many of the Alyn Foundry engines wouldn't exist today, so we all owe him a big debt of thanks.

Best wishes

All rather good though I think I like the slow speed of the running in video best.

I suppose it's time for a lick of paint now, was there a factory colour for these?

Nice runner. Especially are there are no nasty bits trying to chop off thumbs  :)

I thought they are supposed to be a stove or range top engine Andy  :noidea: all of Grahams ones run on his range  ::) . I wonder if they would run on my log burner if they didn't have the legs on the base  :thinking:

Could always make a base like this and use up your twigs Jo :)

Well done Andy.

We just need to get a replacement platform for you in the not too distant future.

As for operation on gas flame that was exactly what the “ squat “ base was originally designed for. There were other bases produced to run on coal with a firebox, grate and chimney.

Love Jason’s picture of either a number 5 or 6 I noticed several foil packages under the firebox, baked spuds for tea!!

Cheers Graham.

Nice little model of a similar engine here by a man after my own heart ;)

Now that my engine runs I'll take it apart and polish the gun metal linkages like this one owned by a friend.

Graham I believe you built this, but the protective coating has been amended.

Jason, I agree I prefer slow running :old:.

Jo,
I can understand you thinking they were meant to sit on gas hobs. However, I'm not allowed to bring engines in the house.

Agreed but the base does get hot enough to burn your thumbs instead.

Hi Andy.

Yes, if it’s  MC’s?

Grrrrr..... they never left me like that in the past....  :)

But time and a constant flow of ground water through the workshop doesn’t help at all!

Cheers Graham.

Yes correct Graham, that one with the modified surface treatment belongs to MC.

Yes I reckon some folk don't appreciate the care that went into acheiving the original factory finish.
