    Ned to cut a welding table down:

    I've got hold of a welding/assembly table which is pretty stout with a 1" top and nearly 10' square. I'd like to get this thing cut in half to make a couple of 5X10 tables, or one 6X10, and one 4X10. I can air arc the stitch welds out to remove the horizontal tubing supports between the uprights, then need a way to slice the table lengthwise. Would a track torch do this alright? Will it deform the table top(s)? I don't have any way to use my plasma to make this long of a cut and it look good or not be jagged as hell.

    Thanks,

    It would be slow going but I've cut 1" plate with an evolution saw.

    I just cut a little 1" plate with my 8" Milwaukee. Pack a lunch...and two blades.

    Torch and straightedge. Get the right size tip and have at it. Be sure to tack in some supports to prevent sagging. I have the Milwaukee saw and would only use it as a last resort, as you will probably burn it up and go thru a small fortune in blades.

    Re: Ned to cut a welding table down:

    Thanks for the suggestions so far. I can borrow a track torch and I'm wondering if my PM-85 rigged up to it running slow would do the job? I know the track torch itself would do it but I'm concerned about warping on the cut edge. The table is blanchard ground and I really don't want to distort it although I really don't require that precision.

    I would use a track torch. Fastest way to go!

    And a MAN air compressor. I guess my 65 would do it with my 7.5 Copco. I'd still use my Milwaukee as first choice.A track torch is a gem but not many people choose this as a "hobby" any more. That's when the Plasma cutter( even an 85) becomes a toy and those two tanks tell it to step aside and "hold my beer".I'm pretty good with a flat bar and an O/A torch but on over 1/2 inch thick---------nnnnnnnnnnnnnn. Gimme a track torch.
    HMMMMMMMMm I do have a Hypethermic magnetic circle cutter with training wheels. Maybe I should take a shot at some 1" tomorrow. I need to raise the jack in my press brake another couple inches.

    Re: Ned to cut a welding table down:

    If you get the right tip. A track torch will give you a cut that will look like it is sawed. It takes a little practice, I don't think that plate will bow sideways. That would be your biggest worry useing a torch. Vertically you can always clamp a stiffener to it to keep that true. Although I don't think it will move in that direction.

    Re: Ned to cut a welding table down:

    This table has nine legs under it and all are adjustable for elevation. I will relocate the inner legs, (stitch welded) and remove the very center one to appropriate positions for new perimeter tubes to tie into. I will be leaving a 2.25" inch gap between the new center tubes, (these will be the new perimeter tubes of the smaller tables) they will run the torch centered between these tubes severing the table. They have a lot of experience with their track torch and 1", and 1.25" plate cutting with it. I will supply the gasses and they will set it up in my shop and do the cut.

    Thanks for the assist.

    Wondering if the torch heat will warp the table top?

    If torch heat can warp it. Torch heat, and a little water can fix it too.

    Not as bad as a crappy shear with a dull blade or a 'tard on a forklift but yeah, a little. Like CEP says. A lil heat can fix it right quick.

    Re: Ned to cut a welding table down:

    Got a call from a gent whom knows another buddy of mine I was discussing a track torch and this table with. Guess I now own one of these things as a gift w/12' of track, extra tips, hose and working knowledge to get me started. The unit was replaced with a plasma table and sits unused.

    Think ole Slob needs to get the guy a complimentary case of beer no?

    Re: Ned to cut a welding table down:

    Once you get the track setup dialed in you should have no problems with warpage. Your cut will spread open quite a bit as your cutting so prepare for that. The spreading is actually a good thing as that will help prevent warping. Should work out good for that and it might be worth adapting plasma to the buggy for use down the road. Good luck with the table.

    Re: Ned to cut a welding table down:

    How about score it 1/4 deep on one or both sides, then only have to torch or plasma through less thickness with less warpage?

    You're most definitely on to something there ! A damn diamond blade in a rented Stihl concrete saw will get some shllt did !Notice the respirator and PPG ! AHEM. I keep tellin you guys. I'm an idiot !Un rigging a rigged koi pond at a zillionaires house in Floridastan. I know more about building pools and ponds than most anyone. Anywhere. I cut the sides of the thing out and installed a dual skimmer to a bead filtration system, buried all the returns and hooked it all up. We brought in real people from all over the US and even a dude from Canukistan( Nova Scotia). Got it done in 4 dayz.
    8 man team....and one really smart chick.I'm just an engineer and saw man. standing on a board with 500K worth of japanese koi in 8 feet of water. Had a guy pumpin KMNO4 into the water over that waterfall to mix at a steady 3 PPM so the debris got neutralized before getting to the koi's gills. Nary a problem.It even got ridda my athletics feet. The real recipe for that is 8 ppm at 1/2 hour. Nail fungii too.

    I would pony up for some scrap 1" plate to test your track torch on before going at the big piece. You can practice and see what settings you need for the torch and speed.

    Tack a straight edge to it and cut with O/A. You should be done by now... A grinder will clean up the edge.

    My bench was cut with a track torch and it's within 1/32 over 8' and nice and straight still. Paid 55 cents a pound for it. Need a new one since it's warped now

    Was talking to another gent whom knows a friend someplace in Texas whom has a 5X10 cast iron welding table for sale. I guess this thing has several "T" slots that take hold down clamps like a milling machine would use. What would be the benefit to a cast iron table other than very stiff?

    It would be much more rigid, pound for pound than mild steel. Usually something like that in cast iron would have lots of stiffener webbing and be thinner overall. The down side is tacking fixtures or parts to the table isn't practical.
