The intake port seems massive. Why? Going to mount a reed valve?

A8VT0R

jef-lemmens

No reed valve , just an old school piston ported engine
Maybe you have thetransfer ports confused with the inlet ?

Cylinder and piston ready

It's been some time since I saw a piston with a baffle, reminds me of my very old ST 40 glow engine.

Or my ancient Fox .78. (Which still runs great and flies the hell out of the Twist 40 it's on!)

It's been a time since I've been able to work on the engine (work on the house). Meanwhile, I have made the crank, I have used Ck 45 steel, here some pics

Once again, very cool, very nice project. I always thought the head fins were probably milled. That's a slick way to do them with the saw.

Where would a fellow get a small carbide tipped saw blade like that?

AV8TOR

jef-lemmens

Thanks AV8TOR , Usually this is done with a sawblade , if you want to mill it with a little cutter (1,5mm - 1/16") you need very high rpm and then there is always the danger that they break with possible damage to the head

The sawblade is from a Proxxon table saw http://www.proxxon.com/en/micromot/27070.php?list

My Feedback: (6)

Yeah. Once again, just an amazing project, and thanks for sharing it. I know how much of a PITA it is to stop work to take the pictures.

But hey, that's cheating to use the mill to make wing ribs...

My Feedback: (4)

I do believe that he was using the mill to drill the jig holes in the ribs, that's not cheating that's smart *L*

captinjohn

That sure is a crude not nice thing to say. First you do not know his abilities & 2nd some people love doing their own work. It is vey satisfying to them. Maybe what you say is not worth saying........

Enco, Grizzley has them saws. Capt,n
