Sadly I think the OP has vanished..... Jo

Hi Andrew. You say you have no experience. Could I suggest you start by gaining some of the skills necessary by making a proven model engine before you try designing one from scratch. This will also tell you what sized engine your machine tools will enable you to build. The good news is that...

I have built a number of Anthony Mount's engines but not that one. I had hoped to make one but the kits are no longer available. Anthony wrote up the entire build back in 1995 in Engineering in Miniature and I can remember discussing it with him. The trickiest part he thought was the side...

I think it might be worth enquiring where you got these part machined castings from to understand what you may have: I know that Station Road Steam recently purchased two sets of Stuart 600 part machined castings from Eric Offen: One set was an original Stuart 600 casting set and the second set...

I also have a Lil Brother air cooled. I can confirm that the Lil' Brother has three 1/16" wide grooves on it and no rings. Jo

Plans and instructions for the Titan appeared in the Home Shop Machinist magazine March 1994. The Engine Collectors' Journal later carried a multi-part construction series on the engine by Roger J Schroeder. The drawings were available directly from Orven Sales Here is my one running: Jo

Is that one of the original Gypsy sets set from Reinhold Krieger or the later sets from the UK? Jo

You also should be aware than many people who publish their designs through ME mags miss out a couple of the parts I do not necessarily blame the original designers… Jo

The owners of the ME magazine will have purchased the publishing rights from Brian and if you photocopy their magazine or copy and extract the drawings from their article you are breeching their copyright. I don't recall Brian actually publishing any of his plans as large drawings separately...

If you know anyone with an ME subscription all of the magazines you are looking for are available in the on-line archive. The individual pages can be printed off as pdfs. Jo

The 6 cylinder engine is a glow plug engine so there is no need to worry about coils. Jo

Oh, a model 60 Elf :) Do you have a copy of John J Brown's book Dan Calkin and his Elfs ? There is some useful guidance in there which may help with some of the more interesting machining challenges. Jo

There are plenty of small pistons and rings around For Steam engines 3/4" are common: https://www.stuartmodels.com/search?qs=ring For model aircraft engines eg: https://www.rcjapan.net/index.php?main_page=index&cPath=80_413_462 companies like OS do pistons as well. Really you need to define...

You need to go and talk to your local boiler inspector: they will explain to you the rules for making boilers in your country and advise you. Jo

I have original Multifix tool posts & holders on two of my lathes, both have DROs. If I take a tool off and change to another tool I just dial in the tool number and it immediately has the accurate tool cutting position - accurate to 0.01mm every time. Except when you move the top slide to cut...
