Cutting 4in square tubing

Hey everyone,

I have a question and was hoping to get some input. I need to cut some 4" square tubing for a customer, and I’m running into clearance issues with my Crossfire XR. In the past, I’ve done smaller 2–3" square tubing on my Crossfire Pro without much trouble, but the larger size is proving more difficult.

I’ve seen a few people create jigs using their slats to help with clearance and hold the tubing in place. Has anyone here tackled this before? What’s been the best method you’ve found?

I’ve got about 100 pieces to cut, so I’m thinking building a custom slat setup for efficiency might be the way to go. Any tips or ideas would be appreciated!

You need to tell us how you are going to cut it. Are you cutting slots in it, cutting holes in it, cutting ovals, cutting it in half long ways, or may be in 6" pieces.

they’re 29 in long that’ll be numbered as shown in the photo I just added

Yea, I would just make a jig that one would fit in and drop them in the table between the slats. If they fill with water it will be better as the doss will not stick to the inside of the tube.

It will be interesting to see the jig after you have made it

I would arrange the slats to fit the box tubing, then lay a piece of plate over the top. Cut out a 90* that the box tubing can locate in, then using the same origin point, cut your tubing.

Worked for me in the past,gonna work again in the near future cutting C-channel for steak pockets.

I realize that you have probably finished this project, but I wanted to show what I was talking about.

Rinse and repeat.

For my application, I am cutting steak pocket uprights, that will bolt 2x12 to the steak, I set a cut for 2.5" of the 3" channel, center line, 0 offset, 0* lead in and out, with a .29" 7 ipm lead in/out feed rate to burn through the 1.25 web, and a 78 ipm cross cut.

I need 42 of them.
