Yes, can get it at Menards. We don't have Menards here on the west coast so I ordered it. Not sure if they have Menards where you are.

Dewalt sells the same exact stool except its yellow.
 
I have been needing some smaller R-8 collets so I went to the local used machine dealer and looked at what they had. They had new imports for $6 in all the common sizes nicely organized in neat stacks or used American made in various conditions, thrown in a bin on a bottom shelf. So I dove right into the bin and started looking. Came up with a 1/16", holy crap! How could you ever not break an end mill that small. I put it back and managed to find a 1/8" and 3/16". The 1/8" was used but clean and unknown maker. The 3/16" was NOS Lyndex in the box with grease still on it. Got them home, cleaned them up and checked the fit.

Unlike my import collets, I don't have to crank them down hard to get them to hold. Just tight and they grip and don't pull down in a cut. Woohoo. I will be going back to dig through the rest of them that were still in the boxes or tubes and see if I can't replace all of my import collets. Heck I may even pick up the 1/16" so I can spin sewing needles in it.
 
I found some more information on that weird fly cutter I got on ebay. It's made by a company called Rotary Technologies Corporation. They specialize in round insert tooling where the insert actually spins as it cuts, thus increasing tool life and cutting speeds.

The insert on the fly cutter does not rotate but is positioned such that it takes a kind of shearing cut rather than a typical plowing cut. They say they are made for lower HP machines. The insert is two sided and still available from Rotary. I found some on ebay for $60 a piece! :eek:

Here's the info page

Pretty neat!
 
I bought an 87 piece metric gauge block set. Even though it was the lowest grade and an import brand, it set me back $171.

I won an ebay auction and bought some unbelievable inserts that can machine the hardest metal (for example a bearing) like butter.
I first saw them here (1:50) where the guy machined a ball bearing.
They are called ELBOR inserts and made in Russia and are cheap.
They arrived today, I made a provisiolal holder for my mini lathe and test them. I could not believe my eyes!
I machined an old bearing at 600 rpm without any lubricants or cutting oil like aluminum!!!!

I will make a proper holder and test it ASAP
