Gene - let us know how it turns out, I'll build one as well when the parts start to arrive. Some of the e-packet shipped stuff from China might delay things.

That video is crazy, it took me way too long to figure out what was happening and how it worked. I was able to figure out about half of what the narrator said allowing youtube to generate subtitles and then auto-translating them to engligh. Is that your video Sergey?

Hey Gene, how did you insert these screws? Am I going to need to buy a tap and die and thread it myself? The instructions don't mention anything of the sort.

I have all the pieces except the HDPE support bars. I have the material but haven't figured out a way of cutting/machining it. I am also re-printing all the 3D parts as I type. I had to scale them up to account for ABS shrinkage.

I did indeed- I used a 1/4 x20 to take the same screws as used by the 1010 fittings- as I recall they did not need to be drilled out, but it was fairly tough threading- If you are not familiar with tapping threads... turn in a half turn and then back out a quarter turn to break off the chips and then repeat- a bit of oil is good as well.

Use Ivory dish soap. Works well. Dustin, if you want I can bring my impact drill and the tap. When making the last CNC Ihad to do over 300 taps and a friend clued me into how to do it really easy using the harbor freight impact and adapters with the taps.
