I have an old Tipp brand blaster that pretty much exactly like the HF one mentioned. I have using it for over 25 years. The lower plumbing came just like the mod. It has no dead-man valve, just a ball valve like the OP's. I have had to replace it a couple of times due the sand eroding the interior of the valve.
FWIW - Nozzle opening will control air volume required. Run the smallest tip that will pass the sand to limit air volume.

weak compressor help?
I have the 20 lb HF blaster hooked up to the cabinet. I was able to clean up most of a double bit axe but my air compressor is very inadequate. I have a 33 gal 150 max psi electric craftsman pushing a whopping 6 scfm at 90 psi (its a joke for sandblasting). I don't really have money for a nice air compressor either. Was just thinking about renting one to complete one project. Would making the air hose (from the main line to the media valve) smaller maybe save some air? I'm going to be using 120 grit aluminum oxide.

I have done the same modifications to mine. Thanks for the tips it works very well. All I have to do now is get an air compressor that can handle air demand.

|gearheadslife||nice write up.. I wonder if I'll have to do this to my eastwoods.... it wasn't cheap... bought it in 1997 and still haven't used it... will be soon.. as the media source for my colapsable blasting cabinet.. as the small ones are to small and the large ones are big bucks..|

|wepuckett||Thanks for the pic and update I figure I can justify the cost of the compressor by doing the media blasting myself and maybe once I have the new compressor I can sell my current one for enough to cover the blasting tank and maybe the air dryer for it. Guess I have plenty of reading to do know. Will post an update later on.|

Here's a pic where you can see my I/R in the corner. I paid $700 for it, out the door but that was in 2006. I think they went up about $300 since then. Mine has the 80 gallon tank.
Probably $1000-$1200 will get you all you need. 5hp is good but 7hp is better! The most important stat you're looking for is CFM (cubic feet of air per minute). Mine puts out a little over 18 cfm. I/R, Quincy and Champion are some good ones but there are others that are even better. I suggest heading on over to The Garage Journal and research air compressors.

What should I expect to pay for one?
What size would you recomend I know 5hp is the bottom line I was wondering if I should target a 7hp one?
Thanks for the advice in advance.

If you do not have a good compressor and very good air dryer system don't waste your money. If you do a search you will find several threads on this subject as well as a couple on how to modify the little pressure pot to make it flow better.
It is better to have a syphon feed blaster as to have a pressure pot with moist air.
And ye,s I do have one and am speaking from experience.

how long does it last
using a 90# tank and lets assume the compressor can keep up and u do one continuous blast.. how long will it take to empty the tank of material. and if someone has an idea of the smaller tank too. say the 40# one.. thinking of getting one but don't have a big use for the lg one.

|evintho||If you can swing it, buy a good compressor. You won't regret it! It opens up a whole new world of air tools allowing you to do so much more in less time. A compressor is an investment. It's something you'll always use. I used to have a 20 gal 2.5 hp Champion that I constantly had to wait for it to build up. Very frustrating! My I/R is one of the best automotive investments I've ever made!|

|wepuckett||NP thanks I had kinda already came to the realization that unless I get a bigger compressor I won't be able to blast myself, not sure if I can try to paint or prime it myself with my current compressor. That will be my next ? to find out. Thanks for responding. Trying to decide if I wanna get a bigger compressor or possibly rent one for a weekend.|

The bare minimum for blasting purposes would be a 5 hp compressor. Blasters use a ton of air. I have a 5 hp Ingersoll Rand rated at 18 cfm. On your 2nd question, it'd be good on a bare frame but both body and frame would take a really long time and you might not be pleased with the results. Hate to be Dougie Downer but those are just the facts.
I think your best bet would be to send the body and frame out to be professionally stripped.

|wepuckett||Ok I am new here and read your post currently working on building an early bronco, I know not a hot rod but still American and still a on topic. Couple of questions here is Do you need a certain size compressor for this to work well? I currently have a 1.7hp craftsman 33 gal I believe. 2nd ? Does this work well if you wanna media blast an entire vehicle as I will need to blast the entire body and frame soon.|

Another two cents worth here....
Evintho has a great idea that can be incorporated simply and at little expense.
The concept is to "fluidize the bed". That is to flow a volume of air up through the mass or bed of media to make it more fluid, disperse water and to reduce consolidation so that it flows more consistently to where it is drawn to the nozzle.
If you're in a humid climate the problem is most prevalent as humidity acts as a glue to hold media in lumps in the supply tank resulting in sporadic or interrupted media flow. Light and fluffy is the answer (does that sound like a laundry product commercial?)
Another approach is to use a vibrator......no, not that one. Air or electric vibrators are common in material transfer systems to prevent or lumping or tunneling. Gawd, they're loud.... maybe not the best for small applications like home media blasters.
