What do you want?

I suppose it is one of those things if you choose to live off the beaten track.

Back to canvasing what people might like in a new casting set which is what I took the opening post to be about.

One big decision is should it be a replica of an actual engine or would a freelance be accepted. Some of your more popular sellers have been freelance such as the CHUKs and RLE. This does have the advantage of being able to keep patterns and parts fairly simple which not only keeps costs down but would hopefully attract more to have a go rather than a complex close to scale replica like a Retlas or Gardner.

Could also be worth thinking if any of your existing patterns could be used. The Nattie with a change of head can be built as a side shaft a sI have done. The Ideal again with a change of head and a second boss for the cam stud bonded into the frame could again become a 4-stroke. Or forget the cam and make it a small epicyclic like the X-type. Just have atmospheric inlet and a rocker arm to do a conventional cam.

I want to be able to go out in the workshop and after half an hour, not get brain fog and to be able to continue making swarf for the rest of the day.

You and me both Jo.
However Jason has addressed the question quite succinctly. Many of the engines I built over the years were based upon those rare and virtually unobtainable full size models that you see once in a while at the steam rallies.

Has the age of the model IC engine come to an end or is it down to the current economic climate?

Ah well, I think the next one will be one of these….

Jasonb:
Didn't Wayne Grenning do one of the similar Sombart Engines as a kit/ready made at one time. It's a nice subject but will it run on readily available gas? or could it have a hidden spark plug at the bottom with just a decorative carrier flame?

Alyn Foundry:
Yes he did.

As of late the curator of the Anson engine museum has managed to get two of their non compression, open flame ignition engines to run on plain, ordinary Propane gas. Apparently the secret is to get the touch hole hot enough so that ignition commences. A hidden spark plug is also another option….  :lolb:

 :cheers:  Graham.

Dave Otto:
As far as I know the Sombart was the only casting kit that Wayne ever offered. All of his remaining engines were only sold as finished  running engines.
