Hey Good People, theirs getting to be so much off topic crap here, its hard to find the gem of metalwork. I have bin welding, plastic cutting, cutting 5mm aluminium sheet for salvaged fans from PC power supplies....welding, measuring, getting it wrong and rewelding after cutting...and lots of other stuff which, if not metalwork, is related as the same methodical thinking and analysis is required.
Who, really, gives a stuff about politics. If you lucky, 50% of your country turns out to vote. Wingers, Democrats - crapping on here will NEVER change anyone's ideas, or how they vote. Are you all Old Farts, for whom the only thing left to moan about is politics?
Global Warming? - who cares, we will be dead before we know if its bullshit or not. Pity about our descendants if the nay-sayers have got it wrong......
Lighten up folks - there's some good people here, with things to say. Lets hear them for a while.
Though I am on the 'one a day' plan, with 200 entries in my Bozo Bin.
BTW, I'm thinking of welding up some wheeled brackets that would allow a contractor friend to easily move 100 lb. sheets of 1" plywood.
Envision a set of bicycle 'training wheels' on a U bracket so that he could roll the sheets individually into position rather than having to dead-lift several, twice a day. I remember having seen something like that in a catalog once upon a time, but not since.
Catalog page cites? Advice? Criticism? Political Insults?
The sheet rock dolly I'm familiar with has four wheels and can hold about 25 sheets at a time . If I understand you want something that can move one sheet at a time into position for fastening ? Something like an extra-extra wide hand truck (aka two-wheel dolly) should work quite well . If you're talking about rolling it over to put on a saw , think carpet dolly type , two larger wheels , so you can slide the ply onto it vertical , then break it over to horizontal at or near saw table height . I usually work alone , and hate to lift heavy stuff ... especially awkward stuff like plywood and particle board .
One question: Have all your posts been on topic? I know mine haven't. But I'm on a path to getting better. If we all would, this would lessen here. If we simply quit responding to the known trolls, they would go find another bridge.
So, I'll TRY to do my part. Not guaranteeing you perfection, mind you.
Sort of. My pal the contractor places 4x8 sheets of 1" plywood on pavers. It prevents paver damage when the skid-steer loader makes it's commute into the back yard several times a day.
One of the guys dead-lifts each of these sheets off the pile every morning and makes a 'wood road' across the driveway. Every afternoon, he dead-lifts each sheet and stacks it neatly in the side yard once again. It makes my back hurt just thinking about this.
I'd like to reduce their medical costs by providing a way to roll each sheet on wheels instead. It'd be cool if the wheels locked when the dolly had less than 10 lbs load, so that it wouldn't roll away when loading & unloading.
That'd work but I don't want the cart to zip into the street, propelled by the angled driveway.
The big-box home improvement stores around here have carts for moving sheet goods around for the customers to use, look like second-cousins to the luggage carts at the larger hotels. Just a 4-wheeled flat with bent tubing welded fore and aft creating slots for the sheet goods to be wheeled around on edge. A couple of the castors are non-swiveling and lockable for loading. The tubing is about 4' high on the center one, the outside ones are more like 2'. Just square upside-down "U"s. Castors are about 4-6" in dia. If a fellow really wanted to get fancy, he could provide some holes in the plywood close to the edges, then put some kind of light boom arrangement on the cart to pick the sheets up to slide them on. Probably a light block and tackle would be sufficient for the pick-up portion with hooks to go in the holes in the sheets.
Aha ha: so if you took the best parts of each of those, welded a couple of big wheels to the side of a 'U' channel with a handle, you could hook the U onto the plywood, tilt it up, and run it over moderately rough ground by pushing one end. To unload,just lay the sheet down, pull the cart off.
BTW, this may not be exactly what you need, but did you ever see the drywall carrier published in _Fine Homebuilding_ ...sheesh, maybe a decade or two ago?
Picture the bottom part of that Telpro thingy, without the wheels, and with a loop of rope for a handle. This lets you carry sheets of drywall with your arm hanging down straight, rather than trying to hold on to both sides. You just put your other arm on the other edge of the drywall sheet (now the top) to steady it. The rope loop is the right length to keep the carrier a few inches off the ground, and the carrier part is made of three scraps of plywood screwed together. I think the configuration should be obvious -- I hope.
Anyway, I use one for carrying a couple of sheets around at a time, with no problem. I also use it for carrying sheets of plywood. It's one heck of a lot easier than manhandling them.
I've been looking high and low for my 6" 3 jaw scroll chuck. I know I have one because I have photographic proof it was on the lathe when I brought it home.

I pulled it off over two years ago to use the 4 jaw independant chuck in rebulding the lathe and sorta lost contact with the 3 jaw. Well, I *thought* it was in the rear of the chip tray until I started looking for it.
Finally I gave up looking for it in my garage and called my uncle to ask if he remembered if I did anything with it when we rolled the lathe to the rear of the garage last fall. He didn't remember anything other than he thought it was sitting in the chip pan.
He mentioned he needed to bring over some tools he borrowed to work on his house and I piped up, while you are over, take a look around and see if you can find the chuck.
I come home today, took a quick look in the machine room and didn't see the chuck so I poked around for a while and gave uncle a call. Uncle tells me he found it and laid it on my lathe. Yup, there it is.
So I ask him, where did you find it? He tells me, on the shelf behind your bridgeport. You had the lid to a cased set of micrometers open that obscured it from view. Hidden in plain sight. I kept thinking the chuck was on the shelf but I didn't see it and I did look. Just didn't fip that lid. Sheese.
Now for the metalworking stuff. The poor chuck is a bit covered with drywall dust. That is the result of me building the heated room for my machines with the machines in them. So I took it apart and cleaned it. While I had it apart, I could see the jaws are damaged. I have a bit of bellmouth at the end. At the rear of the jaws clamping surface, they look fine.
I'm not sure who made this chuck. It was made in England and shows fine workmanship.
Fine enough that the back of the jaws where there are scroll cuts are, the flat surfaces are ground parallel to the slots that the jaws ride in the chuck body which means they are
90 degrees to the damaged clamping surface.
I measured the height of each jaw for reference using the undamaged clamping surface.
Then I put it back together and mounted to my lathe. It has consistant 0.007" run out on various diameters. That could be fixed by bumping the chuck body a bit in relation to the backing plate.
I still have to clean up the jaw surface to get rid of the bellmouthing. For that, I can take a 3x3" right angle plate and stick it to the magnetic chuck on his grinder, then clamp the jaw using the flat surface of the scroll side while using a machinist square to orient things properly. Then grind to clean up, measure, make sure the other jaws are taken down the same amount.
For extra bonus points, I can carefully measure the run out and relationship to each jaw and calculate the amount of grinding variation to get the chuck to center w/o moving the body around.
I'm still looking for the box with all the reamers, dowels, hex bushings, spring wire, fasteners, ect for my gatling build. I now I boxed that stuff up for the time I had my lathe running and in a heated enviroment.

Oh, that is so suhweeeeet! I love that li'l beastie.
Will have to make one, _soonest_ and save what's left of my back!
Remember, guys: HF has those 10-inch pneumatic wheels on sale next week for $3.79 each!
WAIT A MINUTE! HOW'D THIS MAKE IT ONTO RCM? IT DEALS WITH METAL.
