On the bottom - if they are even CLOSE to a corner, it'd be plenty strong - you'd have a pretty large triangle, with just a short part sticking out. That short part would need to bend or break before it'd be a problem, don't think I'd worry about that at all.

Top - that'll work, but is needlessly complicated by having to cut TWO angles on EACH end of the brace - strengthwise it'll be indistinguishable from a simple square tube brace with each end cut @ 45 degrees, even tho that looks like it'll leave a short "non-triangle" section just short of the second saw mount. I would just set up for 45 degree cuts, cut one end of that piece, push the "point" of the 45 into the far left corner with the cut aligned with the left saw mount bar - then mark where the front bar crosses the brace (probably from underneath, using the front bar as a ruler) - make THAT 45 degree cut (probably need to flip the piece over so it isn't backward) weld the 3 sides of both ends that are NOT gonna stick up into your saw base - Then do the top welds; if you're using stick, I'd go with some pretty flat running rod like 6013, small diameter, and don't stop til you're at the other end :laughing:

That way, if you need to grind it won't be that much, and it might even MISS where your saw base sets.

Underneath - yeah, I'm gettin' up there too, turned 72 in May - here's another thought; if you have enough headroom where you store the "porta-shop" you might wanna have those in/outfeed wings flip UP instead of down; whether that works for you or not, it sounds like some heavy duty drawer glides and at least one full-width drawer under the cart (like for saws, squares, long clamps, etc) might ease the pain. At least with drawers, it's usually a bit easier to get at the contents than if they're just on a SHELF.

Oh, and I wouldn't be surprised if you're gonna need some kind of thin sheet directly under the saw, or else end up cleaning sawdust out of that drawer constantly...

You probly oughta stop listening to me; I'll have you STILL ENGINEERING this thing NEXT year at this time ...Steve

I just backed up and reread earlier parts of this thread - noticed you already had the plan of in/outfeeds pictured in post # 15. Without a scale, it's hard to be sure - but it looks to me like your in/out wings are already short enough that you could use a 2-piece, telescoping leg centered on each one that, when collapsed, could fold up UNDER that leaf for travel - I've found that each successive 1/4" in square tubing size will "nest" into the larger one, IF the wall thickness of the outer tubing is .095" - the next wall thickness up in standard tubing is .120", and that does NOT leave enough clearance for a comfortable slip fit.

If you were to drill 1/4" holes in the inner tubing every inch for maybe 4-6" either side of exact length (when on flat ground) it'd give you plenty of adjustment for uneven ground.

For feet, one of the easiest ways I've found is to start with 1/2" allthread (most bolts don't have full-length threads, so you only get about 1" of travel or less) - using 3-4 inches of allthread, you MAKE a bolt by plug-welding a NUT on the end - add a heavy, large washer on the end of THAT, and you have a FOOT. Then weld a COUPLER NUT onto the lower half of your telescoping leg, screw the FOOT into that, and you have plenty of room to "split the difference" between your 1" spaced holes.

I did that (on steroids) for an old slip roll I found on CL - I also changed the framing so I can pick it up with either my loader forks, cherry picker or a pallet jack - Those are 5/8 bolts, and the "washer" on the foot is plasma cut 3/8" flat bar. That roll can put a curl in 4' wide 3/8 plate without even grunting, so I figured it needed "good understanding"... Steve

Now that sounds like a plan. I had thought I was probably twice your age, but turns out only two months. Maybe I've got twice the miles? At the rate I've been going I will probably still need ENGINEERING this time next year (which will be a good thing). With a possibility of rain I am very reluctant to move everything 'into' the shop, so I spend a good bit of time listening to someone read me a book on CD's. I hear so poorly that it takes a good voice for me to understand but it's better than trying to listen to TV. I have to turn it up so loud that when the commercials come on they even hurt my ears.
