How long can you blast with a full hopper ?
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.Quote:

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.
Baking soda- no. it is water soluble and so fine, there is no way of filtering it. Some say other media can be filtered or sifted to be reused. Would also need to have large metal particles magnetically removed I suppose. might be ok for rough blasting where you don't care about the surface Either way, sifting to the proper size is key or you will gum up the works.Quote:

As for cost- "grocery store" baking soda is about 60 cents per pound. Commercial blasting soda is roughly 75 cents per pound. Not a huge difference but, I don't have to worry about keeping a 50 lb bag dry.
Again- no expert here, just sharing what works for me (right now).
I have a "sucks" entry...
Heavy Duty Chain Breaker
The description says that it will work for bicycle chains. It will not without some modification. I had to take the pin to a grinder and reduce the size of it in order to fit the chain I was working on. It seems solidly built, but the design is poor. It's heavy and awkward. There is no good way to align or hold the chain. The pin does not fully retract into the bolt without some outside pressure.
In general it was clumsy and hard to use. I should have spent the extra few bucks and waited the extra day to get a nice chain tool from Amazon.
That thing looks like it was made by a blacksmith. :laughing:Quote:

In the background are various handmade tools hanging on rusty pegs.Quote:

It reminds me of a comment my dad made to me about a trailer I had bought that had a few questionable welds on it. He said, "That looks like it was welded with a shiny new welder."
I like this alternative.Quote:

The next thing he says is "I can clone anything Harbor Freight sells, and offer mine to them cheaper".
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. :D
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.Quote:
