Just a little more from 'Tired Iron'. . with a couple of pictures of a log saw that I would like some information on.

I haven't restored this rig yet. The engine is a two-cycle. It has no throttle or governor. The speed is controlled by hand with the timer. The cooling system is of the thermal siphon type, with hoses from the water jacket up to a round tank. The tank has a rectangular shaped filler. This filler has baffles in it. I suppose these baffles are to keep water from splashing out and to condense some steam.

The gas tank is the same shape and mounted next to the water tank, making it look like all one tank. The gas is gravity fed to a Lunkenheimer carburetor. Under these tanks is a rather flat shaped compartment to hold a buzz coil and a hot shot battery. I would like to know if this compartment had a cover and how it was made.

The saw and the linkage that operate the saw is very much like an Ottawa, but is chain driven instead of gear driven.

The water jacket has the words R.M. Wade & Co., Portland and Spokane cast on the side. The main bearings have grease cups. There is a hole tapped in the top side of the crankcase. I suppose this is for a drip type oil cup, to oil the rod, wrist pin and cylinder. Would this oil cup have the usual ball check in it to hold the crankcase pressure or would it have something special? Would this oil be enough for the cylinder or do I have to put oil in the gas as in some other two cycle engines?

1927 Dodge cut down for pick-up. GP wide tread John Deere 1931 model and A Case combine. One of first ever to do custom work. It traveled all over Sioux County, Iowa. Taken in 1941.

My log saw that I would like to get some information on.

The bottom end of the wood framework that rests on the ground seems to have something missing; maybe a wood pad or an adjustable leg to keep the frame high enough so that the saw crank doesn't hit the ground. Can anyone help me out on this? I would like to know what color it may have been and what year it was made.

In the March-April 1968 G.E.M. on page 29 is a picture of a Sieverkropp Gas Engine sent in by Ronald L. Walsh, Hampstead, Maryland. I have an engine identical to it. It is also a two cycle engine with an oil cup to oil the cylinder. Is this enough oil for the cylinder or does it need some oil in the gas? This engine is quite small with only a two inch bore and two inch stroke. Does anyone know the RPM, horsepower, color, the year made and for what it was used?
