    Challenger V8

    Finally finished the Challenger V8 from Coles and what a challenge it was for me. I still need to make a few improvements to the carburettor but it is as good as done. It can sit on the shelf for a while now as I have started another Holt 75, I sold the first one I built so maybe this one will...

    Challenger V8 questions.

    Thanks for your comments. The build notes that came with the castings mentions the possibility of one bank being smoky and suggests that a reduction in oil pump size may help however I'm not really keen on that path. It has had very minimal run time and I suspect that the rings have not bedded...

    Challenger V8 questions.

    I have just managed to get my Challenger V8 to the running stage but have a few questions that those who have gone before me may be able to help me with. I have built it to the plans, that is, without oil rings and when viewed from the front of the engine the left bank of cylinders is smoky when...

    I have been offline for a while but I notice that Project of the month winners have that noted on their profile. I was lucky enough to win it in Feb 2014 but it is not noted as such. Is this an oversight or was it not policy back then? Thanks.

    Challenger V8 or alternative?

    Mark, It is almost finished, needs a carburettor and some tweaking to get it running. Have put it to one side for the moment to work on a Forest and Gallice from Lone Star Engines.it was a lot of fun to build. Do Coles Power Models still sell them? Cheers Graeme It appears I am well behind the...

    1888 Forest 4 cyl from Lonestar Engine

    Just found Maury's announcement on Model Engine Maker. I would suggest buying whatever you can from him, you will not be disappointed. What a loss to the hobby this is.

    1888 Forest 4 cyl from Lonestar Engine

    I am about half way through my build, castings are brilliant as are the drawings. It is not a beginners engine. Sorry to hear Maury is closing down, does anyone have any more info? I think my castings were set number eight, I will have to check.

    Can anyone help me with info re the above? I have tried contacting Cooper Tools with no result, are they still in business or is there another source of supply? Thanks Graeme

    Hello Mike, I used a CDI ignition system from Roy Scholl, I never had a lot of luck with igniters or rather, I lack the skill and determination!

    Centaur side shaft engine first run

    Hello Jason, the changes are only cosmetic, extra flywheel, magneto. It won't be governed. It is critical that the mitre valve for the carburettor bears heavier on the lower seat than the upper, otherwise it will not run, they should idle at about 450 to 500 rpm when bedded in.

    Centaur side shaft engine first run

    This engine is to the Edgar T Westbury design with a few minor modifications, my patterns and castings. I thought I would fit a fake magneto for appearance, when complete the plug wire will come from the magneto pickup. Still a lot of work to do however this is an encouraging start. The magneto...

    Slag and cast iron

    With all due respect, there is a lot to learn. Could I recommend any post by 100model on HMEM. He also has many videos on YouTube and debunks a lot of myths about metal casting, especially cast iron, on which, IMHO he is an expert. When I first started pouring metal the mantra was...
