Hey MC,
I have similar thoughts to George's reply but here is a method for
cutting timbers larger than a saws cutting depth;
Make a fence around the sides of the timber to guide your circular saw
on all four sides. After cutting you will be left with a small nib
that can be cut with a hand saw or recipricating saw. That last cut
won't be perfectly smooth but the edges will look nice. Hold your
breath for each cut! Seriously, wear some type of respiraory
protection. Maybe wet down the area so the dust/chips don't blow
away.
Would your miter saw be able to make a contiguous starter kerf on each
face? If so, that's a simial approach to my first suggestion.

I have six pieces of pressure treated 8"x8" railroad ties (8' long) that I
need to cut into short, 8"-10" long sections. What is the best way to go
about it? I can't use my compound miter saw with such a large cross
section, and I am not sure I can get a clean cut with a circular saw (not
with my skill level). Any suggestions?

Thanks,

MC
