Nice engine. What rings did you use? Andrew in Melbourne

I found that the fuel mixture has to be spot on to work. I use a vapour carburetor of Jan Ridders design worked well. Timing was not my biggest concern as i used a CDI system. It pays to check for spark regardless which ignition system you use. Aslo check plug gap. The local mechanics say they...

I used 0.4mm Jointing gasket material. The gasket is between the head and the shoulder on the cylinder where the bolts are. I found the compression quite high and used an electric drill to start it. Cheers, Andrew in Melbourne

I found the solder with rosin core becomes "globby". The struff without is easier to control. Cheers , Andrew in Melbourne

Short answer, No that solder is not suitable. Cheers, Andrew in Melbourne

BillWood, I don't know what size the engine must be fore breath power is not enough. Good question and I hope there is an answer. Cheers, Andrew in Melbourne

You will need a larger compressor to get higher speed. I tried a similar setup and had the same results. I was able to get 50rpm using an aquarium pump. Cheers, Andrew in Melbourne

What do they call in here in Australia ? When I asked about corian they did not know what I was talking about . Cheers, Andrew in Melbourne

Does anyone know where to buy corian in Melbourne? Cheers, Andrew in Melbourne

I have found that they are pressed on. I have removed many of the gears with a slotted metal plate to support the gear held in the vice and a drift/pin punch to drive the shaft out. Cheers, Andrew in Melbourne

Bill, Flywheels can be made of aliminium and work. Heavier materials are usually used and help when running slow. Cheers, Andrew in Melbourne

Nice work. Is the flywheel steel? Cheers, Andrew in Melbourne

I forgot to put the video link. An FYI is I am a high level quadriplegic. If I can build one you can to. The rings were made using a rear brake cylinder from a Mini, I think it was a 1968 model. The inside diameter of the bore is 19mm. Piston was aluminium bar and the crankshaft was machined...

My Webster was built a few years ago. I posted the footage on youtube.

The DRO on my Mini-Mill is one by Yuri's toys. A Google search wwill find it for you. Yuri supplied the controller. The scales are purchased from any suitable source and the display unit is a tablet or phone. It may seem complex but following the instructions got mine working like a champ. The...

Wonderful. Thanks for sharing. Cheers, Andrew in Melbourne

The bronze bushes I made were reamed and left in a reamed state. The crankshaft was polished with 1200 grit. Be careful not to go undersize when polishing. Rather a few scratches left in the shaft, which will aid lubrication, than undersize and have to restart. Remember the engine is not...
