Well that would work 32, but that would be like pulling the plug out of the bucket, throwing it away then waiting for all the the sand to run out. I'd like to have some control over the process, guess you could say that I'm a "control freak". Can't see broadcasting 100 lbs of blasting media into the driveway and only applying 10% of it to the task at hand.
The air needs to be shut off before it picks up the sand and at the same time you need to gate the sand from gravity/pressure feeding into the hose. So you need some sort of a double valve that you could control from the business end of the hose. Short of rigging a double solenoid with a trigger on the nozzle it’s got me stumped for now.
It’s funny how when you get into something like this the basic flaws in the equipment become obvious almost immediately yet they keep on producing and selling the same thing for years. It reminds me of the majority of reproduction parts that we get from the vendors, you have to rework most of it to make it fit or end up throwing it out and making your own.
