That's right. I've come up with a way to use this office chair as a guide for my chainsaw.

 The chair has a metal plate which sits perfectly level. A piece of plywood bolted here, would allow many pieces of equipment to be held firmly and swiveled.

The pressurized piston allows it to go up or down by 6 inches.

The wheels could be used on a very smooth floor to move it along a firmly placed log.

Or, on uneven ground, the wheels could be removed and instead a smooth piece of plywood attached to the feet. This would be slid along an extension ladder which is laid down as rails.

I don't imagine using this to do fine woodworking. Instead, I will use it to cut thick cants for future processing.

That's it for now. I've got the basic concept and I will bang it together soon.

Pretty nice. A few sticks of angle iron could also be tacked together to form a rough guide for those caster wheels to ride in.

Okay, so if you're NOT DALE and you don't feel 100 percent comfortable doing this. You probably shouldn't use your office chair as a chainsaw mill.


Dale,

Awsome. Just, Awesome.

Thank you Landon.

 If the leg of the chair is mounted horizontally it turns the chainsaw into a chopsaw.

This could be very handy for the  processing of firewood or for timber framing. 

On a double swivel, you have a mitre saw.
............. edit....
Make a mobile chopsaw by attaching two pieces of  2x10 in an L-shape, as when building a corner.

Mount the leg of the chair onto the 2x10s and the saw would be mobile and could be carried to a big squared timber, held in place and used to make a nice square cut.

I used this system twice, just to prove to myself that it could be done. I don't have a suitably smooth piece of concrete at my disposal.

I have found that for pieces less than 6 feet long, I can do a pretty good job with a free hand cut. After a slab is cut, I run the saw along it, with the saw barely tilted, so that I am able to plane off any defects.

Thick slabs change dimension as they dry, so there is no point in going for a super smooth finish. Further working is required once the wood is dry.
