Yes Tom. Bob is scratch building a A10 Warthog with a 10 foot span. It will be powered by two of these turbines. Combined they produce 28 lbs. of thrust.

Excellent.
The Warthog is on my list of planes to model. All I need to do is figure out how to get more time.  I played around with some foam scratch building techniques a while back and was considering using them on a ducted fan electric version of the A10, but ended up doing a Gee Bee model D Sportster instead. Got a lot of the building techniques worked out though, so maybe I'll have to give it another shot.

How about .22 rimfire? Although then you would have to register your model airplane with the ATF, unless a model chaingun is somehow NFA exempt.

Nah... R/C flying is expensive enough as it is. By the time you add in a LLC, and a SOT stamp - you don't have any money left for fuel.
 I would have liked to have met the guys that designed the warthog. I would almost bet they were rednecks. "Hey ya'll.... Lets take this here cannon, and build a plane around it! Here - hold my beer....."

I bought a couple of cheap aluminum (aluminium) squares to use for welding setups. Of course, they weren't square nor did they have any flat surfaces so I set them up on the mill and made two of the surfaces square and flat. I still need to mill the 45 degree angle but that can wait for another day.

Exciting day today! NOT.
I had a small plastic cover that has been bouncing around in the back of my car for a couple of weeks now. It finally got to the point where it was starting to bug me... It's just an access cover for the high mount stop light on the back window of the car. The little plastic fastener that holds the cover in place decided to break in half and gravity did the rest. I was going to make a new one from aluminum but of course didn't have the right size stock on hand. So I went with brass instead. Marked out the spacing on the brass round and turned the sections to size, leaving a little extra on each end for support and to be able to hold it in a collet. Then over to the mill to cut the flats of the "key". The square 5-C collet block made quick work of that by just rotating the block in the vice. With that done it was back to the lathe to part off and face the support ends. Over to the mill again to cut a screwdriver slot in the end cap to be able to turn the fastener and lock it in place. Just a plunge cut with a key seat cutter. (I forgot to get a pic of that.  )Not much to show for all that back and forth...
