Not sure how this was one of the first things I made for this engine as it is one of the most intricate parts as there so may curved surfaces on the smokebox for Miniature [more…]
Making a copper boiler end plate with a mild steel pattern and firstly hammering the outer edge over. I made a mild steel pattern for the copper end plates to be formed over. The final [more…]
The transitional engine eccentric bracket supports the pivot for a bellcrank midway along the pushrod. This is the part in question, machined from mild steel with phosphor bronze inserts. As you can see, there were [more…]
The idea was to build a small 5 cylinder rotary engine that runs on compressed air, the crankcase for the five cylinder rotary would be another challenge. This is a rotary engine where the crankcase [more…]
The master conrod for the five cylinder rotary worried me since the beginning of this project because there is so much involved in machining it. Machinging the small end of the master conrod with it [more…]
The design of a wood and metal steam beam engine.
This is the initial process of machining the piston for my single cylinder poppet valve engine. This piston is being machined out of cast iron, I can hear the screams of how heavy this will [more…]
Threading and then bolting into aluminium can be troublesome. Also, the cylinder design of this poppet valve engine means there is no space to get the bolts in between the cooling fins and the cylinder [more…]
The poppet valve crankcase has been bugging me and I wanted to fix the brackets from inside the crankcase with countersunk caphead bolts. There just wasn’t room or the right angle to get a bit [more…]
The crankshaft for the poppet valve single cylinder engine has been machined from mild steel and includes timing gear machined directly on the shaft. This started with a piece of hexagonal mild steel, why hexagonal? [more…]
