Fred Marks replied, "Gene- I took the cheap way out when I bought my blaster.
It's a 40# Central Pneumatic pressure blaster from Harbor Freight Tools. I
paid $74.99 on Sale and shipping was free."
I too bought the 40# blaster from HF. I love it!!! I also have on of HF's
plastic blasting cabinets (the $130 one). I also love this. Which I use
depends on what I'm blasting. Small parts go in the cabinet, for large items
I use the pressure blaster. I also have a syphon blaster. The pressure
blaster does a much better job and a lot quicker than the plain syphon gun.
I drive all the air tools from a 5hp 30 gal oil lubricated Craftsman
compressor.
As to the HF's pressure blaster, I also agree about the bad ball valves.
One
the handle broke off while I was assembling it. I would make a couple of
modifications. Also, my dryer is missing the fitting for the drain petcock
and I never call HF. I really should do that one of these days and see if I
can get just the petcock.
I can blast for about 1 hour by regulating the sand output before I have to
refill the tank.
I would make a modification to this pressure blaster if you should get one.
They supply a short union to connect the dryer and pressure guage to the
unit.
Go to the hardware store an purchase a slightly longer union. You can't get
the guage, dryer, etc on or off with the handles attached if you don't.
A couple more comments but not about the blaster but about blasting:
1. For a frame, I wouldn't wast my time. Blasting is very very slow work!!!
I will send big items like that out to be blasted. I find it very cost
effective. I paid $125 to have the chassis for my Bricklin blasted. It
would have taken me days to do it.
2. When I blast, I tie a rope diagonally across the corner of my fence. Then
I attach a 6mil plastic drop cloth to the rope with clothes pins. This
gives me a back drop for the sand to hit, and a floor to collect the sand.
I can recover about 85% I shoot. So 100# last quite a long time. I scoop
the sand up in a coffee can, and sift it through an old piece of screen
back into my storage bucket. Then I fill my blaster from the storage
bucket.
I also lay a piece of cardboard or plywood on the plastic floor to keep
from punching a hole in the plastic with the parts I'm blasting.
3. Besure to get a good hood with the replaceable lexan (or what ever it is)
shields. Sand will go everywhere.
Hope this helps.
