There are 10 pages of works drawings with these castings ::)

just a shame they are meant to work with another engine :LittleDevil:

Hi Jo.

You're one of an " elite " group....

CHUK 2 was never " drawn/sketched " you're one of a handful that have got that particular model. I believe there's less than half a dozen ever made.

When/if  Surrus let's you get started I'd be happy to participate in the build log.

Cheers Graham.

Thanks Graham,

It looks to be a quick build so I am surprised there were so few sold. We will have to see when I am allowed to do it as the Seal and the Major are longer term builds (I am also working on the Triples every now and then ) it could well be a useful engine to recover my sanity if I get bogged down.

Andy had already spotted that this casting set came with the full set of original drawings that covered all three Chuk models rather than the later typed up version which seemed to have lost some details, so I have scanned the drawings and let him have a copy to go with that set of Chuk 1 castings he told me he has  :stickpoke:

Good morning Jo.

Hmmm, that's interesting, missing pages!

As some will know, Alan my fatherinlaw took over the running of Alyn Foundry after my heart attacks. Unbeknown to the family he was in the early stages of Alzheimer's disease. At the time Alan wasn't very happy with my " handwritten " notes and had attempted to redo them in a neater fashion. From what you've written it would appear that a section has gone missing.

I too was perplexed after reading your post from yesterday it prompted me to look at the originals. I couldn't find any reference to CHUK 2 whatsoever!

Would you be so kind and let me have a copy Jo?

Cheers Graham.

PS. What's with the poking, are you looking to expand the CHUK family?    ;)

I'll have to send them over  ;)

I noted that you have some additional castings for the Chuk 1 and it would be nice to make both versions :) And based on past experience I am sure you wouldn't want to supply them to someone who complains all the time about castings  :hellno:

Don't worry about me, I have my A frame should I decide to make the set :LittleDevil:

Having recovered from a very frightening experience last Monday  :paranoia: I have been back in the workshop and finished off the seal connecting rods.


The bottom of the seal rods are turned so that they just fit down the bore of the cylinder. the top of the rod has to have an oil hole drilled in.

Then The fit on the crankshaft was tested. Two of the big ends had a small shoulder which left a mark on the connecting rod side :ShakeHead: This has been removed by countersinking the outside of the rod.

Finally all the rods are in place and rotate freely  :cartwheel: I now need a crankshaft for the Major. If you recall a few pages back I had marked up a piece of 38mm EN8 to make it out of, so Mr Silky has it mounted up ready to go  :)

Coming along well Jo. The assembly of the crankshaft and rods looks excellent!!

The shape of the little ends for the Seal are very neat.  :ThumbsUp: :ThumbsUp:

Are you going to shape the bronze Seal Major the same way?

Thank you Bill/Mike,

The Major little ends have already been done like that  ;)


There is a lot more to making these multi cylinder engines than just simple single cylinder engines (other than the quantity of parts needed )

Did I mention that the last count of casting sets for four cylinder engines to make, including these two, was 8 9   ::) I think I will deserve a nice fast build single cylinder engine next  :)


Edit: updated count as I remembered another 4 cylinder engine I had forgotten  :old:

Guess that will depend on what Surus is willing to part with  :lolb:

Quite so. You could always have a go at a fully detailed 1/4 or 1/3 scale radial engine if you want a challenge.

I have 3 nine cylinder radials to make and another 3 radials with less cylinders  :facepalm: I'll save the detailing for something else  ;)
