3D model description

I designed this engine to fit in a 1:5 scale Sopwith Pup I am designing.

The crankcase / cylinder halves were printed on a Creality Ender 3 without supports and with only a skirt - no brim or raft. The inlet tubes were printed with the fronts facing up and with supports and brim turned on but with the support overhang angle set to 80 degrees to minimise the amount of support.

Pushrod rockers have holes to allow the insertion of 16swg piano wire (or 1.5mm carbon fibre) pushrods.

The joining ring is glued into the front half of the engine prior to assembly and ensures good alignment of the two halves.

This motor is also a bit porky. All-up weight with piano wire pushrods is around 140 grams (5 ounces). However, most WW1 models end up tail heavy so a bit of extra weight up front never goes amiss. Scale detail trumps a lump of lead every time.

This model is now available printed in various scales from 1:7 up to 1:3. For details, see Scalercengines.com
