Hi all am gathering materials to build the Bentley BR2 rotary engine, have the book by L K Blackmore but was wondering if anyone has a set of drawings for the said engine. On that line has anyone started one and it is now lingering under the bench unloved and would like to sell it or parts on.

I am looking to make a Steam Siren for my traction engine. Can anyone point me in the direction of some drawing for one please. Tried goggle but nothing comes up. Thanks Bob

Hi all I have built a Hoglet and before trying to start it I decided to use my newly constructed compression tester. When turning the engine over I get 50 psi max but it drops off to zero, is this OK or should it hold the pressure, if so for how long.

Hi I started building Rodeys Tractor and decided to make it more like a Case 65, you will notice the tapered stack. I built a 3" version about fifteen years ago so adding improvements from memory and pictures of mine. These few pictures are of the flywheel clutch which I have now finished and...

A few days ago there was a discussion on valves leaking / seats, I have this problem with my Cirrus and joined in the conversation, but my problem was sort of side stepped with no suggestions. So I thought if I started a new discussion some one might have an ideal. I have just finished a...

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...

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,

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...

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

OK chaps I am now on the last stretch of building my 1/4 scale Cirrus, which is the carburettor. The drawings for the spray bar show a .005" thick slit in it. What have other builder done to achieve this, is it possible to get a slitting saw that size. Or could I drill a row of holes, which...

Hello all I am building a Cirrus 1/4 scale as per Zimmerman design and using SIC drawings. I have built all the bottom end including cylinders and pistons and my next task is the oil pump and distributor, followed by the heads. As it is all complete to this stage and I like turning it over by...

Hi Guys I have started to build the 1/4 Cirrus aero engine as per the Zimmerman design. To date everything is going as planed, I am now at the crankshaft stage. Which calls for some chrome moly steel 4140, well I have hunted and cannot find any. So I have decided to fabricate from silver steel...

Hi all I have completed a Hoglet fitted with single Hall sensor that is triggered by two magnets, and using the lost spark system. The Hogletl is as per the drawings and the gear to which the magnets are fitted is of brass. My problem is I can turn the engine over by hand to set the timing etc...

The progress continues with the valves, valve guides, springs and keeps all made and fitted.

The progress continues today the cylinder heads were completed. Caused a bit of head scratching a few times but all worked out well. The jig for holding the heads worked really well to.
