    T-Head Engine Plans

    When it comes to the castings, just assume any mating surface is a machined surface. Therefore a mating surface in the casting is undersized. For this engine, I didn't use any cores in the castings. ...Ved.

    T-Head Engine Plans

    Thank you all for the encouragement. As I wrote earlier, I built the engine and failed. I was never able to get my valves to seal. I don't think it's the design, I think I just suck. For those that question the long valve lifters, I did have a problem with alignment. That's why I added the...

    The great O ring discussion

    Oh hell, not again. This hobby is dying. Why make the barrier to entry more difficult by criticizing how people make their engines? The whole "you're doing it wrong" does nothing but push people away. So what if someone wants to use sealing method over another? Give it up.

    Engine Valves

    I give in. This engine has defeated me. I started with spool valves. I redesigned to poppet valves. I made the poppet valves and cages again. Hell, I trying to get a single fire and I'm using ether (starting fluid) as a fuel. No luck. The plans for the engine (with 3D solid models) are...

    T-Head Engine Plans

    Ok, For me, this engine was a failure. I just couldn't get the valves to seal worth a damn. I don't necessarily think it's in the design, I think it's because I suck., So in the following few posts, I present the design for this four stroke engine. If anybody tackles this thing and is...

    Engine Valves

    Yeah, I did that. I also took the head and with the valve(s) and valve guide(s). Spring loaded them from the rear and turned them in the lathe to lap the valves. That's how I got the very smooth finish on the actual mating surfaces. (I think I just suck.)

    Engine Valves

    Thus far all my attempts have failed. I've redesigned the engine for poppets and made the valves and vale guides twice. My second try I get a bit less valve leakage, but no engine run. Not even a single fire with ether as a fuel. (Yes I have spark). I have no compression. I can turn the...

    Looking for a good way to learn solidworks

    I've been using professional CAD for 25+ years now. I've used Intergraph EMS, Solid Edge, Solidworks, Autodesk Inventory. I've played with Alibre and FreeCAD. They all have different workflows but in some ways are also similar. I recommend to just do the early, built in, SW tutorials. Don't...

    How can I find a good home for my father's steam engine

    I don't know if they have any money, but Carillon Park in Dayton, Ohio has a model steam railroad. http://www.cprss.org/

    What to charge to thread a rod

    David, Go to misumi.com. It's a Japanese company with a US distribution. You can purchased customized machined parts from then and the prices for the custom part is right on the configuration page. I'm my profession, I use them frequently. In your situation, I'd configure 24 rods without...
