Steve, I think the hot weather is getting to you. 
I got all 20 of the 1/4" cap pieces cut today, and 8 of 'em de-glazed, beveled and ready to weld on - my plasma View attachment 563712 cuts 1/4" steel at 60 IPM, which makes it real handy to just lay a ruler along the back edge of the 1" angle I use for a guide - View attachment 563713 ever since my military time I can count seconds accurate within about 1 second per minute, so I just hold the torch against the guide and move it past the inch marks at one per second - works pretty good - View attachment 563714 View attachment 563715 - The ones standing up against the pyramids are the finished ones...
We had a couple cooler days (low 80's) which was nice; but the next week (starting tomorrow) is supposed to be mid to upper 90's - it'll get too warm for playin' with HOT things by around 11am, so I'll probably start fabbing 2 templates for cutting 16-1/2" square and 24-1/2" square holes in container walls - the first of 4 of these
Greenhouse Ventilation Package - Greenhouse Exhaust Fans | Greenhouse Megastore
will be here Monday (I'm getting the 1620 packages; they'll exchange the air in a 40' container once every two minutes) - I'm gettin' tired of making rounds morning (open containers, turn on fans) and nite (turn OFF fans, close containers) - some of the things stored in 'em do NOT like 130-140 degree temps, so the 16" exhaust fan will go on the leeward side opposite the door ends, and the 24" motorized louvers will go on the leeward side just inside the doors. The included controller can then get set to maybe 90 degrees, so I can goof off another hour before I gotta pretend I'm doin' sumthin USEFUL
The templates (which I can make in the wood shop (already HAS a 24" gable exhaust fan and 2 other fans, yay) will let me cut the holes with the plasma from INSIDE, MUCH less of a PITA than tryin' to do it with a zip disk :thumbsup: - I checked and all 4 containers have exactly the same corrugation spacing (even tho they're two different manufacturers), so I'll only need to make one of each size template (yay) to do all 4 containers -
Time to hang it up for the night, need to get going fairly early to beat the heat... Steve
This square tube into square tube is more like a square tube into a rectangle tube as in POST 410> 4th picture? yup should've had that picture of that dramatic episode, what was you thinking, now dont blame it on the heat............One of these (minus the "U" bracket jig) - View attachment 563606 - In my case, it's a 20 ton press - the tubing in question is 3" wide, - 1/2" for 2 quarter-inch walls leaves 2-1/2" for the 2-1/2" tubing that I pushed inside - as you probably found out, the electrically welded SEAM gets in your way. My need was just to beef up the wide tubes so they wouldn't crush, so I used a zip disk and did a small "furrow" down the side of the small tube (it's still1/4" wall, so no biggie) - then I ground a short bevel across the end of the small tube on 2 sides so it'd START a little easier, I lined up my "furrow" with the weld seam on the bigger tube, couple taps with a small (32 oz) hammer, set the whole thing on the press, used that "Tee" pusher in the pic, and held the air on the air/hydraulic jack til it looked halfway there...
No welding necessary, there's enough tension to keep it from moving since any force is only gonna be trying to squeeze things closer together, NOT push the small tube back out sideways......Steve
