Im looking to build my last model due to my eyes letting me down a little now and fancy a simple mill engine like Persious. Ideally would prefer something twice the size but cant find anything. Im not up to scaleling it up just want a kit of castings. Can you help do you know of such a model. Cheers Alan.
If you are OK with working from stock materials rather than castings, and to metric dimensions, there is also 'Vulcan'. This is 38mm bore by 50mm stroke with flywheel 215mm diameter. This is very similar in style to Perseus. Send me a private message with contact details and I can send you a copy of the drawings. John
