Best way to cut 8" nontapered column

I am looking for a tip on the best way to cut the back 1/4 off an 8" non-tapered column. I have a Dewalt portable job site table saw which I thought might be the way to rip one side at a time but not sure how to secure it along the rake for an even straight cut. Build a square frame to the column? Use a lazer line to draw my line and rip with a swazall? Lazer line and a skil saw with angle set? Any advice would be appreciated! Thanks.

Make a router sled

Tack 2 rails, one on either side and at the appropriate height
to allow the router to make the 1/4" depth of cut as you slide the router mounted on a base of 3/8" or 1/2" plywood which will extend beyond the sled rails. Then walk it back and forth until all the unwanted material is routed away. Use a dado bit or straight cutter. Like this: http://www.ptreeusa.com/freud_mortising_bits.htm

BTW I'm assuming this is a ROUND column.....?
Otherwise it would not pose such a problem.

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

Snap a chalk line and cut it with a portable circular saw.

If you just had a couple, I think I would just mark a line and freehand cut it with a skill saw especially if it could be caulked and painted. If there was very many to do or the cut needed to be more precise I would construct a cheater board to guide the skill saw. Another option is if the column doesn't have any cross grain trim it could be sent over a jointer to mill the back

I would like to learn how to use a chalk line with a circular saw. I tried it a time or two and the air from the saw blows the chalk away.

Something is a bit unclear about your description. I have a few questions to get answered in order to make an educated guess.

You say it's an 8" column.

Does that mean 8" x 8"?
What is the column made of (what is the wood)?
If the column is hollow, how thick are the walls?
What is the length of the column?
If the column is made up of 4 sides, how are they joined?
You say "take off the back 1/4. Does that mean 1/4", or a quarter of its overall dimension?

Your chalk is old and dried out, you need some new, blue for beginners, red for pros, Japanese ink lines for masters.

That's true, but the method would work for any shape

That can't be. I always throw away chalk before the expiration date on the bottle.

abandonded thread

Doncha just love it when a thread is started with insufficient info, replies are given to the best of our ability, then poof, he gone..

We don't even know if the column is round or square or what length. At this point I don't give a rip anyhow.

Yeah, but look at it this way, at least we all learned to look for the expiration dates of our chalk before using.

BTW, Where can I find some purple chalk? I can't use the blue because I've been at it for many years, and there is no way I qualify for red so I figure I should probably be using purple.

Don't get all strung out about it. Why not just take the red certification test. We'll all help you study for it, and you'll pass for sure. It should be a snap.

You can't use purple, when a beginner makes a mistake with blue, the pros snap over it with red, which turns the line purple. Mix some yellow and blue and go green. You can charge more.

I've been holding off using red chalk. When China takes over we'll all have to use red.
