Re: Stabilized ChainSaw Bar?? Accuracy needed.

[Ed]

I'm not exactly sure what you are trying to do. Are the cuts 90 degree, or are you trying to cut the miters and leave tenons?

Have you considered using a portable bandsaw?

Use an electric chainsaw.

Ed, I want to do two things:

- Cutoff of up to 8x12 beams, well squared end.

- End cuts to produce a tenon on beam ends

A bandsaw that has an 8 inch clearance is big and expensive. I'm trying to find/design a low-cost alternative for the once-in-a-while framer (me!)..

A sharp chainsaw with a unworn bar and chain makes a pretty accurate cut if well controlled. I want to build a sort of "chainsaw chop-saw" which controls the saw movement. Not usual 'freehand' at all.

[Terry King]

That's exactly what I intend to do.

The issue is that the 16" long bar will deflect sideways with a small amount of pressure: about 1/4 inch with 1 pound force approximately. This is enough to cause inaccuracy in cuts even if the chainsaw body is rigidly restrained.

I want to build a mount for the saw that will reach out and support (relatively) rigidly the far end of the bar. This would still leave about 12" of working bar.

I think. I'm hoping someone has done something like this, OR can point to something like this, OR point to why it's a really dumb idea...

While living in the Berkshires, one of the nearby property owners hired some folks to do some logging of the trees. . .The loggers had a rig set up on a flatbed trailer with a humongus such chainsaw chop-saw. You might talk to some loggers for starters.

there is a add on tool for a sidewinder saw like a skill 77 that is called a beam cutter made by pratzi it has a about a 12 " bar that hangs down from where the blade would be retaiils for about 120 to

I looked at this product; it does not add any stabilization to the far end of the bar, and I believe that is what makes some of the chainsaw mills work well: the bar is held solids at BOTH ends...

I'm close to a trial design for this, using 1" and 1.5" square steel tubing in the frame; I hope to be trying it out in about 10 days...

I have 8 by 8's 16 feet long in my yard as of last night, and cutting time is coming fast...
