Re: TWIN 32 x 38 mm - steam engine for small boats or canoes

Hi,

then the forks were rounded so they will look nice and go free from other parts. I had built a milling fixture and panned the parts by hand.

Then the borings were reamed and the M5 x 0,5 mm threads cutted.

Re: TWIN 32 x 38 mm - steam engine for small boats or canoes

Hi, kozos books are one of the best i know. The eccentric rods are ready. It is a composite construction. The head is soldered to the middle part and that is fixed with three M3-screws to the outer eccentric bodies. I have built a soldering fixture so all four rods will have the equal length. Twin32...

Re: TWIN 32 x 38 mm - steam engine for small boats or canoes

Russ, ... The next phase would have the stroke-adjusting disc position controlled by the boiler water level control, to automatically maintain water level... Probably not, the mechanics should remain simple. ;) ;) ;) There was some little success. The piston rod gland nuts were finished so it is pos...

Re: Better Piston Rings

Peter, unfortunately I don't know the context in which you work, so it's difficult to give good advice. I have used gray cast iron piston rings from engine construction in all of my current steam engines. But because they have a small gap at the joint, I use two pieces in a groove that are offset by...

Re: Better Piston Rings

Peter,

are there any pictures of "Courflex piston rings"? That will help a lot for finding a reasonable answer.

Re: TWIN 32 x 38 mm - oil pump eccentric with adjustable stroke

Hi, because I've been having trouble sleeping lately, I found the time to draw my idea of an eccentric with an adjustable stroke, here's the result. Ölpumpenexzenter_kplt_Explosion_20220306.jpg The eccentric consists of a fixed disc, which is attached to the shaft with two set screws, a movable disc...

Re: TWIN 32 x 38 mm - steam engine for small boats or canoes

Wesley, the engine will be mounted on two longitudinal beams with eight bolts. Twin3238_305kl.jpg To achieve a universal design, the base plate can be rotated about the longitudinal axis to build a clockwise or counter-clockwise rotating engine, depending on which direction of rotation the propeller...

Re: TWIN 32 x 38 mm - steam engine for small boats or canoes

Hello, in this threat i want to show, how i built a small steam engine for different purposes, especially canoes and small boats because there is no one on the market and there are no drawings available. I am interested in finishing it and if it is tested successfully i will optimise it. This moment...

Re: TWIN 32 x 38 mm - steam engine for small boats or canoes

Hi, in view of the questions and comments, I would like to recall the first few sentences. ------------- There was a second cylinder block when i got my steam lorry MARTIN because there was a water hammer on the steam engine so that the cross head guide and the piston rod were destroyed. I repaired ...
