In this restoration I tackle the largest project I have done to date! This is a 1920s drag or log saw made by the Ottawa Mfg. Co. of Ottawa, Kansas, USA. This is a TE model with a 5HP 4-stroke engine on it. The saw mimics the sawing action of two people using a non-powered crosscut saw. The saw blade itself is 5ft long.
I have not dealt with 4-stroke engines very often in my restoration history, so it was a lot of fun learning along the way.
The tool itself shows signs of many repairs over its ~100 years, including a lot of brazing due to large frost cracks and completely broken castings in other places. The wooden base is rotting away and is cracked in many places as well. The magneto does not produce spark and the piston is stuck as well!
In this video I tackle the disassembly as well as make new parts or repair parts when I can
In the final video I will paint parts, reassemble, and test it out on a log!
I would like to thank Evapo-Rust for sponsoring this video.
