T model

[sbdtasos]

hello my friends
i have decided to start a model engine with one cylinder
i have used a 3-4 PT Thread-T Shaped Equal Connector for engine block
and then trying to fit on it the crank and cylinder.

I'm impressed with the finish on your bore. Every time I try to use a boring bar in my mill, I get crap.

Any insights?

This caught my eye...looking forward to seeing it through.

Very nice! Why do you use 4 ball bearings?

Beautiful. Is this engine being built from plans available by Dale Dietrich? He designed and built one using the brass "T" fitting.

yes this engine is copy of Dale Dietrich engine
i saw his engine and it was like a dream
i dont have plans for this engine i make all the parts same scale as 3/4 brass engine block

because i was afraid for the crankshaft not to lose the balance
is better and more stable

and now we have the cylinder with piston and rod

This is very interesting. I will follow your build.--Brian Rupnow

hello again..
here is my cylinder head with valves..

I'm interested why the heat marks on the valve stems?

the heat marks are because the valve is not from solid bar
is 2 separate parts that is weld with silver
i know that is not the best way but it works

Love your build.

How do you attach the cylinder to the crankcase? I am guessing you need more then a press fitting.

Wonder if a boxer type engine could be built with one of these?

with this cross gave me a very good idea..
as you can see in the first foto exist on the cylinder liner 3 holes M3 at 120 degree (you can see only the 1 in the picture)
when was installing the cylinder into the brass block i was lock them with this 3 bolts
but after a little use this was not so good idea
and change the way that locking the cylinder foto 2
is better and until now is in working condition

Saw a 4" cast iron cross fitting on the web today. Would make a pretty impressive sized twin cylinder engine.

here is some photo from finished and ready to run engine

Awesome engine! I like the little water tank (or fuel)...very cool.

 

[Brian Rupnow]

How do you get oil to the connecting rod at both ends?
