I built this large turntable and use it regularly.   I will hold a cabinet, table top, dresser, large chair, bed, a bunch of smaller items, or whatever I need to finish.   While it works with a brush or rag, it's really handy with a spray gun where you can finish one side quickly, then roll on the next, or to do remaining edges.

 

It's a sheet of 3/4" CDX plywood cut in half, plus a couple of scraps.   I use 1¼ " and 1½ " black pipe that nest in each other just right.   When you're at the store, test to make sure yours do. They're attached with floor flanges.   You can use two different lengths of the larger pipe, and one of the smaller to get different heights (depending on whether your work  is tall (desk) or shallow (table top).   It comes apart easily and stacks against the wall if you need the space for something else.  The red ring is just a cap that the company uses to protect the threads during shipment.  It provides some lubrication, but is not really necessary.  Got this idea from Michael Dresdner.

 

That's really cool!, I like the height.

 

I have a similar setup that uses a reclaimed lazy susan bearing. 2 large pieces of plywood that sandwich the bearing. Sets on a pair of sawhorses when in use. A thru peg keeps it from rotating when I need it to be rigid.

If anyone would like to build their  very own "heavy duty" turntable - I just repaired the wife's car.  A rear wheel hub.  The old one can be yours for shipping!  It is heavy.  It turns fine but was beginning to make some noise in the car.

Keith please explain to all the back of that spray booth has filters and a fan.  Does the fan push filtered air over the peice being sprayed or does it pull dirty air over the peice being sprayed but does take in the overspray?

Or is there a post on creating a spreay both?

 

I fabricated the spray booth from 2x4s and Masonite.  In the back there is a chamber maybe 2' deep where I mounted a whole-house attic fan.   If I was spraying a lot of lacquer and stuff, it really should be vented outside.   I am spraying mostly w/b finishes and stains, and it's in the basement, so I have to forego that.  What you see are just some furnace filters.   When I had it, I had some fiber cloth in front of it.  I got it at a garage sale from an HVAC guy who said they used it in new construction to run the fan and clear the air (from what I don't know but I presume dust and drywall sanding.)    The idea is to pull the overspray away from the work and into the filters and exhaust any fumes.

 

So from the top it  sort of looks like this (with a lid over all):

What you can't see is the lighting above and on the side of the booth.   Coming up in a future TGIF.

 

This fit a lot better in my old shop where there wasn't a door right in the way (on the right) and a lower I-beam across the top.

 

Some of the finishing books have portable spray booths made from medium to large cardboard boxes or sheet vinyl sides, box fans, and generally set in front of a window or garage door.   When I did some classes, they had a commercial spray booth that I scoped out.

A followup question the amount of air flow is low med or high? I am wondering how high the fan has to be to pull enough air to eliminate overspray.

 

I don't know what CFM, but I'd say it's relatively high.   The gun and settings determine overspray -- your objective is to capture what you can.    I leave it on while spraying and for a few minutes after.

I have one copied from one of Jeff Jewitt's books (Spray Finishing Made Simple)  that is at least a distant relative to that design. Mine is considerably smaller (roughly 2'x2') and on a mobile base, but uses the same setup with pipes making the turntable possible. That wheel hub that Cal shows would really make a sturdy one...I'll have to remember that if I make a larger one.
