I've been a user of Parallax products for a few years, having done a few LED blinky lights and following along in the Nuts and Volts articles.
One big problem when building a project is getting something mechanical made when your specialty is in electronics. I've been in that situation, and over time, I've built
up a small shop in my garage which currently consists of a Bridgeport and a 6" lathe. Sometimes you need just a slot in a piece of aluminum, or a correctly
bent piece of sheet metal to mount something properly inside an electrical panel. Sometimes you need something more complex like a linkage or a specialty bearing.
I can help if you need something made up.
Just PM me your design, and I'll let you know if it's something my shop can make. Sketches on paper, or on Google Sketchup, or even Autocad, PM me and I'll see what I can do.
Reasonable rates.

Yes. That's not a big deal, just a matter of using the correct speeds and feeds with the right bit.
PM me a drawing, plz.
Can you swing a 24" long PVC round between centers and apply threads to the round? The round is 2" diameter with a 3/4" bore. It needs 8TPI for the majority of the rounds length. The threads are only to act as turns for holding wire to make a coil... The material is green PVC...

No sorry. My lathe isn't big enough.
If you aren't too particular about the dimensions and number of threads per inch, you could just thread up some PVC pipe. But be aware that when you buy pipe, it's nominal, not actual.
2" pipe is 2.375" actual diam.
1 1/2" pipe is 1.9" actual diam.
Then, the number of threads per inch is 11.5 per inch standard.
Getting exactly 2" OD, and 3/4" ID would require a bigger lathe, which I don't have.
I am an owner of a small machine shop that can submit to your dimensions you have specified. I must require $60 dollars an hour for my time. Does this require a part that I must buy or are you going to supply the materials. If you supply the material does it have a 3/4 hole thru it? If it does not please explain the total runout that is required. I have the capability to use the three pin method to supply the correct pitch diameter within .002".or even closer by using a .0001 indicator and a precision micrometer for the final readings. Does the 2 feet have to be completely covered with threads? If it does I will have no problem with catching up with the threads and running it throught the two feet as you specified. You are in control of how much this part is going to cost you by supplying the tolerances. I have for most of my life held tolerances of +- .0002 which have been necessary for progression dies but not really required for every day necessitates. If you supply the material and it has the 3/4 hole and you give me .06" tolerance and I have .5 with no thread it will cost you about $30 plus shipping. Anything more will cost you more money, you get what you pay for. I am close to the central part of Pennsylvania and am waiting your reply.
