Status: offline 		Hi all. How does one remove the black cylinder on a Wenmac? There are no wrench flats. Is it a permanent press fit?

Thanks,
David

Status: offline 		Anybody got any more tips for the disassembly and reassembly of this type Wen-Mac? I just acquired one as a kick-in to sweeten a trade and have no clue about them except for starting a couple other types in RTF C/L planes and cars owned by other kids on the street when I was a kid.

I'm thinking this could be a "project" engine for my nine year old son. Take apart, examine; clean; reassemble; and, hopefully, run.

Anything you can tell me that might help would be greatly appreciated.

Status: offline 		As a small improvement to the "wrench" make that second part of the slot a little longer and end it wiht another hole the same size as the cylinder hole. It makes the wood both more resistant to splitting and more flexible to squeeze with less pressure.
