I made a roll-around cart using 5" swivel casters. It is sorta like
the borg ones, except has wheels on each corner of a 2' x 8' platform
that has a center T-vertical support that holds in place 4 (or more)
1/2" conduit rods that keep the sheets from tipping over. The
concept seems to work well, but when loaded (about 20 sheets), "roll-
around" becomes nearly stationary. I had some 5" x 2" wide swivel
casters. They have an outside "tire" that is rubber-like. Even with
all wheels aimed in the same direction, it's extremely taxing to move.
Would 10" pneumatic tires make a difference? HF has them for about
$15 each. I'd imagine 20 sheets is pushing 1500#. That is fully
loaded though.

That would be the communist woodshop way of doing things -
redistribute all of the sawdust on the floor equally all over the
shop!

Use a "nascar jack" for brakes on the cart - pull the handle and the
weight is on the jacks and off the wheels, and the cart won't roll
away. Need to move it? Flip the lever up to drob it onto the wheels
and push.

It could help. Some of the problem is the squish of the tires, so
either replace them with much harder tires (polyurethane is wonderful
here, just don't use it for a finish ;) or add more squishies.
I use 5" casters by default and they allow me to roll over my air hose
if need be, and to overcome debris on the floor (as if I'd ever let
that happen in my shop...)

Untill you come to a bit of crap on the floor that stops the iron
wheel dead in it's tracks, while a rubber tire deforms over it and
keeps rolling.
The 10" pneumatic tires at HF that I buy for carts are on sale for $3.49
this weekend only (ok, until they put them on sale again, that is).
They are rated for 300 Lbs I believe and have a 5/8" bore.

What about adding more 5" casters? I have a plenty -- I could add 4
more and further distribute the weight? The four now are located 48"
apart , 2 foot from either end of the platform (where the T support
fastens). Maybe I add one to each corner of the platform.

I have been intending to try some of the green slime you put into tires to
make them self sealing. I'll let you all know how it goes.
Before you say, "don't do it- it makes it too hard to change a tire", know I
replace wheel and tire when I have a problem, usually.

Still, if you're going to use pneumatic tires, pick up the corresponding
tubes. Tubeless tires on dollies and the like are usually a problem.
It think they go flat because they don't get enough fresh air.

Remember also that a wheel that works perfectly well in daily use like
at the Borg may flat-spot if it's sitting in the same place with a load
on it for months at a time.

Just put a skirt (bicycle inner tube, perhaps) and an air fitting on it,
and hook to the compressor when you want to move it. You need about 0.65
PSI to float 1500 lbs on a 2' x 8' base - unfortunately a bit over
typical shop vac blowing pressures (and likely too much leakage for most
air compressors to keep up with.) Might be a sweet spot with a venturi,
but probably loud as all get out.
Then again, hard wheels and a broom work quite nicely.

What is your floor?
Assuming a hard floor (concrete or plywood) a harder caster tire is
going to help - diameter is plenty big at 5", but the "rubber-like" tire
is doing you in, I suspect. A very hard rubber/plastic or plain
steel/iron wheel makes for less rolling resistance. Heavy mill carts are
nearly always noisy cast iron wheels, and roll easily with thousands of
pounds on them. If your wheel allows, you might just want to remove the
"tire" part. Putting on pneumatic tires will be going the opposite
direction...

You are asking the castors to do a pretty heavy job. Get wheels like the
ones under the carts you fashioned your cart after. Take a closer look at
the Borg cart wheels. Wheels that stay perfectly round, all steel or steel
with a thin hard rubber tire, are going to provide the least resistance.

Bigger tires have less trouble rolling over bumps, little bits
of scrap, etc. 20" mountain bike wheels would be perfect.
They seem like they'd be well up to the task of hauling 20
sheets of 3/4 ply:

Alright.. so a little background on why as 20-sheet cart.
I wanted something I can slide a sheet out partially and have a look
without re-arranging the entire stack. A few years back I found 10
birch-maple sheets for $20/each or so. Then there is the misc 10
others -- a few MDF, few 1/2, few OSB, cutoffs, etc. I wanted to be
able to push the cart against the wall, but then pull it out, spin it
around, etc, etch when chosing a sheet.
It's based on this one, http://www.scrgeek.com/woodwork/storageSheets.html
I swapped out the pvc pipe with conduit pipe of smaller diameter (more
ridigity with less diameter). moved the T-verticle supports about 24"
in from each end, made the base 2' wide (as narrow as possible), and
beefed up the internal bracing.
I wanted to conserve floor space, so I made the cart 2 foot wide.
Less the 3.5" for T-support, less 2x3/4" for pipe verticals, less
2x1/2" on the outside, leaves about 18" of max useable deck space. So,
in theory 24 sheets. If I used the extra 4 spacer conduit, that would
consume another 4x3/4" for a min useable deck of 15". So about 20
sheets.

It doesn't happen very often, but WTF? Air hose is cheap enough and I

If you have problems moving the cart straight ahead when all the
casters are aligned in the same direction, then either the casters are
overloaded or you need to eat some more to beef up as you don't have
enough mass. The first scenario would benefit from extra wheels.
Your wife will have input on the body mass thing.
If the problem pushing the cart around is primarily turning the cart
when the wheels aren't aligned, more wheels may help or may hurt.
Since you have plenty of casters, throw some more on as a test and
find out if that helps or hurts.

Why do you want to roll around 20 sheets of plywood?

Don't disagree w/ any of the other responses; I'd note, however, it's
likely the bearings on those casters as much as or more than the actual
diameter or tire that is the problem. Don't know what those would be
rated for, but 1500/4 -->pushing 400 lb/each. I'd reckon that's
probably at or beyond their recommended loading.

Those HF tires are hit-n-miss and I wouldn't want to find out if I got
good or bad ones after they're holding up a 1/4 ton. :-)
They tend to leak over time and it sure does suck to have to inflate
them every time you want to move the cart. Spoken from experience. :-)

At the time, yes. But we can all laugh in hindsight, right?

If you build a floating platform, you can flood the shop and those
little pieces of scrap will just sink to the bottom and the wood cart
will float, freely above.
Is it that difficult, people?

I was so freakin foggy this morning, I didn't even catch the typo.
I honestly want to hear about air losing its density from getting stale.
Another oak rust tale, I suspect.... but maybe it's true.

The key to getting decent casters at HF is to hand pick them by checking
how tight the bearing assembly is. Some are a lot tighter than others
and the loose ones can loosen more under weight, making them difficult
to turn. I've even had some lose their bearings, altogether.

Nice drive-by. My sheet goods are leaning against the wall behind the
paint shelves in a 1' space left for that purpose. If I could roll
them around, there is nowhere to put them.

10" would make a difference, but I don't know about pneumatic. If they would
flatten a bit it would be even more difficult to move. If you check
McMaster or Grainger you'll see the loading recommendations. They will be
considerably more than $15 though.
