Shake an' howdy from Skywrench

[skywrench]

Shake an' howdy all around. I've been lurking for a while, but thought it time I introduced myself.

Mostly I wrench on General Aviation piston airplanes, but not full time. I know this is a little different corner of tool selection and use than many on here, but still find this a lively and useful forum.

Welcome to the dark side. We cookies

Hope you like your stay here.
Got pics from work, by any chance? Never seen inside those motors.

Welcome, had to do a double take when I saw your Name. I have a number of customers that live in a development called SkyRanch in Carefree Az.

AndrewV, thanks.

I see where my post pointed toward powerplants, but more of what I do is airframe. I'll see what I've got for pix though.

Mostly, these are fairly basic 4- and 6-cylinder aircooled Boxer engines, think big VW, pretty crude 1930's-1950's technology with dual magneto ignition, pretty wide static clearances due to wide range of thermal expansion challenges. Fairly low compression ratios, from 7.20:1 to maybe 8.50:1. Crude up-draught carburetor, or mechanical fuel injection in the higher output applications, manual mixture control for leaning at altitude.

By way of example, a Lycoming 0-540 has six cylinders of 90 cubic inches each(roughly 1.5 litres, or Beetle-engine size). Flat-rated power from 235-300hp at 2575-2700 rpm typical.

Thanks, eh? skywrench
