Instructions
A little tricky to get together and a couple of approaches work so its up to you but here is how I did it. Look at the picture for some reference, the crank shaft is symmetrical and the same one as my 4 cylinder motor and the pistons have room on each mounting rod for two.
The pistons mount to the connectors with 3mm filament.
It helps to put the crank shaft together without the ends that it pivots on first, don't forget to put the pistons on as you go.
Then I put the piston and crank assembly in the cylinders then glued the blocks together. I used Krazy glue but what ever works for you, acetone, hot glue, etc. The cylinder blocks mount on each others end but note their is a rounded corner, I did this for a nice feel in your hand when holding the motor.
Finally I put in the two small rods that the whole thing rotates on and the crank handle.
Your done!
