I would recommand building a Procut type chainsaw mill and just mount the
chainsaw vertically instead of horizontally like you would with the Procut.
It would be easy to make a indexing mount that would let you set the angle
of the blade to the bed.

You can decide if you want to buy the plans for the full mill or just build
your own H carriage. Having a sawmill is handy if you live in the woods.

I built one about 2 years ago for under $350 plus the cost of the chainsaw
and of course the plans.

Here's the link:

Has anyone seen a chain saw device that has the
'far' end of the bar stabilized for more accuracy?

I need to be able to cut off up to 8 by 12 beams,
and do many partial cuts accurately for timber
framing. I want to modify a couple of electric
chain saws for this work.

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.

The closest thing I've seen are chain saw mills that
support both ends of the bar. But they are specialized
for ripping logs etc.

Also there is a device with a 'follower' blade that mounts
on an adapter circular saw, but the end of the bar and blade
are still unsupported.

Any pointers to designs or existing tools that use a
bar stabilized at both ends would be appreciated!

If I get something working I'll show what I did...
