How long can you blast with a full hopper ?

... I use standard grocery store baking soda with good results. The only caveat is needing to adjust the lever to control the flow of powder. I think this is only because the "grocery store" powder is so fine as opposed to actual blasting soda. ...

You may want to drop by your local feed mill and see if they sell agricultural baking soda. It works much better than grocery store baking soda. At my local feed mill I can purchase a 50lb bad for around $12.00.
I'm guessing about 5 minutes of fairly constant blasting. I'm working on a throttle body and intake right now- so not very large areas. Keep in mind, I'm still working on dialing in the flow rate. When I get a better idea, i'll let you know. Should be in a day or 2.
I'll look into that. The grocery store stuff is really fine although it cuts through fairly well. I'm sure the coarser stuff will work better and quicker. never would have thought of a feed mill as a possible source- THANKS!
Isn't there some way of recovering/recycling the blasting media, or is there a very good reason why you can't, other than cost.
I asked my BIL, who used to rebuild super expensive old racing cars, to blast off the layers of paint on my boat's anchor.
not quite his usual job for sure. When he was done he said he spent more than a hundred bucks in baking soda on the anchor.
Wow. Made my case of beer pretty inadequate....
I know baking soda is the number one choice here for certain work, but seems the consumables will eat you alive, no pun intended.
That thing looks like it was made by a blacksmith. :laughing:

I like this alternative.The alternate image is a young 20-something chinese entrepreneur wearing trendy clothing standing outside his newly (cheaply) built factory full of new (untrained) employees.
When I started out in the car business in the early 80's, this is the way American car parts were sourced, too. Multiple manufacturers for the same part - some good and some ..ah...not so good. :laughing: It turns out that price isn't everything..........
And that's why HF often has several stock numbers for the 'same' item - they keep getting lower bids from different vendors and need to keep straight who sold them what.
