Sieg lathes are the classic 'Chinese mini-lathe' so may well sell under different names / colours worldwide (Grizzly I think in the US?). Anyway...

    A pair of Boll Aero 18s

    Hi, after completing my first engine (Webster) and procrastinating for 6 months, I have finally taken the plunge and decided to build my next engine.

    First I/C engine build - Webster

    Hi All, I have just completed my first I/C engine build. Got there in the end and runs nicely (not perfectly but good. I still need to play with carb, exhaust valve and ignition timing a bit). This is my first post on the forum too so will be a bit clunky before I figure everything out. It...
