Nice piece of workman ship, well done.

Well done and a great job all round in the design and casting.

One of the cons for this engine is that it is non reversing. It is timed to run in one direction, to make it run in the opposite direction it has to be re-timed.

Thanks Dave

Hello again in 2007 I built a 3" Case 65HP which was sold on three years ago. I now intend to build a 3/4" scale Case to Rudy's design with some improvements. One of the improvements I would like to add is the proper clutch like I had on my 3". The annoying thing is I can remember the...

Hi chaps my Cirrus is now complete and I have stripped it down to build it back with gaskets and O rings. All has gone well so far I made a jig to make the head gasket that went really well, and well worth the time. I was then reading an article on testing the valves, which involved making a...

Great job I will be following progress.

Brilliant thanks very much.

Hi is there anyone out there with a copy of "Rudy's Model Steam Tractor" sat around collecting dust, preferably in the UK. I can buy the book from the US but the postage is $35 which is more than the book costs. If you have and would like to sell it to me let me know,

That workshop looks too clean and tidy.:o

Charlie, all done thanks again. Bob

Charlie, thanks for your very thorough answer and I now understand. I knew where the pipes had to go my problem was the joint at the rear end. Now you have explained it its obvious, the old brain just needed a kick start in the right direction. My brain has stoped hurting now so it off to the...

Hi this is to those who have finished the Cirrus 1/4 scale engine. The drawings do not show the pipe work in the sump for the scavenge pipe or the feed pipe above on the oil tray. What have others done and how did they connect it to the two oil connectors in the rear casting. Any help as I...

Thanks for the pictures of the casting. I have been in contact with Mike and as we speak a set of castings will be winging there way to me. Yes cast iron is the best thing for cylinders, which was going to be my plan anyway. So this week the postman will be busy delivering castings, drawings...

Hi I believe that the castings include the crank case and cylinders, I will let you know if successful. Chewing the crank case from the solid was my next option should be reasonabley straight forward, just more swarf.

Hi Dave, Yes we will have to make a date for August, lots of catching up to do.

Hi thanks for the links, I have sourced the drawings. Thanks to you I have sent a message via Model Engine Builder to Mike Cole about castings, but don't hold out much hope as I have read that he is not active on the site. Once again thanks for your response.

As my Cirrus project draws to an end I am looking forward to my next engine. I have decided to build the Anzani "Y" 3 cylinder engine. This is a long shot but,has anyone out there got drawings, castings laying around wanting a good home. Or indeed advice on the build in general. Bob

First thanks for all the reply's I received, from these I was able to resolve my problem. I found I had some small 3/4" diam saws in my Dremel box, but were too thick. So I just mounted one on a mandrel in my lathe, then using my tool post grinder I slowly ground the cutting blade to .005". I...
