jeff2wings Posted April 12, 2020 Author Share Posted April 12, 2020 Hallem Nipper This engine was made in Poole Dorset pre-war and was supplied as a part machined kit for the home constructor and is typical for engines of this era with some unusual construction features (to modern eyes) with both the crankshaft and piston being made in three parts.This engine was started by some one a long time back and given the standard of work was abandoned as a "bad job" and let in a draw.So, let's see what we can make of it. old and new.the crank originally was made in three parts,shaft,web and pin the new one is two parts ,shaft and web with integral pin and this is the piston ! I will make all this from scratch as the yoke looks like it's a casting,will use some HE 15 for this and rod Quote Link to comment Share on other sites More sharing options...

jeff2wings Posted April 13, 2020 Author Share Posted April 13, 2020 It's just a grade of aluminium,aka T3 .That's the thing with these 'pioneer' engines all made to original ideas in order to get the best functioning engines,or in the early days just to function at all ! How about this one for quirky ? no air intake venturi just a fuel metering valve Made a new yoke today and piston body out of EN 1a (steel) that I will case harden the gudgen pin made larger 3.1>4 mm Quote Link to comment Share on other sites More sharing options...
