Minh-thanh started the thread, then designed and built his own diesel engine. No small achievement.... So on this this thread I think what he says goes and we keep this thread to fuel injected CI "diesel" engines. Perhaps a new thread could be started for a more general discussion on compression...

That name plate looks great on your lovely radiator 👍

Very nice job

Check out Ades Workshop on YouTube and drop him a message he is a time served machinist that has a Warco WM180 in his home workshop. He has done a few upgrades on his lathe. I'm sure he would give you an honest opinion of it. Another youtuber with a WM180 is Retro Steamtech again I am sure he...

Those conrods are tiny.. excellent work I like the epoxy technique as well 👌

Hi Bob Terry mentioned he used SAE660 which I googled: SAE660 or C93200 is a Leaded (Tin) continuously cast bronze and is a standard in the industry for light/medium bearing applications. Leaded (Tin) Bronze SAE660 or C93200 is suitable for various applications under medium loads. Cheers, Dave.

Malofix There is a free plan for a vertical slide on the model engines website that you can download: https://www.model-engineer.co.uk/news/article/free-plan-cross-vice-to-vertical-slide/22255/

From the woodworking teacher on my preparatory yacht & boat building course at college. "Keep it as long as you can for as long as you can"

Hi Malofix this is what Steamchick was referring to: Compound Slide – Chester Hobby Store Called a top slide or compound slide, bigger lathes usually have them as standard but you would have to buy or make one. On my lathe from I would use the top slide for a steep angle like 45deg Cheers Dave

I bought some rings from Otto Gas Engine Works for the Jerry Howell "Powerhouse" engine I'm building. I figured I would hopefully get the engine running with the Otto rings and then try making my own.

Excellent work Minh-Thanh 👏

If there is a marine propeller shaft manufacturer nearby they might be able straighten it for you as they will be used to straightening prop shafts. Some marine engineering workshops or other engineering workshops may also be able to do it for you. Cheers, Dave.

This is the same lathe from a UK supplier. If you don't have the manual for it. You can download it from them. I think it is a Sieg C1 lathe https://www.chesterhobbystore.com/shop/metalworking-machines/lathes/cobra-lathe/...

In the UK & EU emissions for this sort of engine (NRNM) Non Road Mobile Machinery are regulated by EU Type approval EU 2016/1628 (now Stage V). Since BREXIT this has been a retained regulation until 01/01/2022 at the earliest. These regulations apply only to items "placed on the market" I.e...

Certainly at today battery prices I suppose it depends on the cost of the replacement in the future when the batteries are dead or capacity drastically reduced. I imagine companies will pop up doing refurbed battery packs etc once the demand is high enough.

Standard practice on full size engines is to space the ring gaps evenly, so 120deg with three rings. Most engine workshop manuals are particular about the installation position but as Tornitore says they do rotate position when in use anyway. Lubricate the rings in the grooves well before...

Glad your getting it sorted 👍 Cheers, Dave.

Hi Todd I didn't realise they weren't public. I know of the names Kerzel and Upshur but that is about it. I've but an Elner's Wobbler from Elmer Verburgs plans a Unit Steam Engine wobbler from their kit, a PM Resesrch mill engine from their kit and my latest build I've started which will test...

Another way of looking at it is that a commercially produced engine based on plans in the public domain is an affirmation of the design and plans. The availability of these assembled models means that the finished engine is available to a larger audience who may not have the...

Looking at your photo it isn't 20UN as per your thread gauge. Is 20UN same as 20 TPI? It looks like it is a coarser thread. 19mm would be very odd so more like to be 3/4" What is it fitted to as that may help identify the thread. Cheers, Dave
