First Engine No Plans.

[HYTECH]

Well I last year I bought a 9x20 lathe and a JDM-15 mill (RF-31). Never machined a thing in my life but after reading ALOT and tearing up parts and tools I started to build a single Cyl IC engine 1.4" bore 1.4" stroke. No plans just out of my head. one or two parts at a time. Forgive me if some parts look rough I'm a newb and Cheap tooling sucks.

first I started with a cylinder and Sleeve

Then I went for a piston But I probably won't use this one.

Next is the head.

(edit) I did end up not using this head design.

I went to make the cooling fins deeper and had a crash.

Then the dreaded crankshaft. It wasn't as hard to do as I though but man it was slow going.

It took me a year to get this far. But I'm excited now so it should go faster. It defiantly was a learning process.x

Nice series of photos, and an impressive build!
I've gotta say, I could HEAR the chips coming off that drill in the second photo. ;D

I think you just graduated from "newbe" to "experienced". That is great work. Thm: Thm: Thm:

Very nice HYTECH.
You may not have any plans, but you sure do have a clear idea of where you are going.
