i built a set of bars based on this idea (thanks!) using different materials.  I used 20mm black delrin bars that i bought on ebay.  Was super easy.

Step 1)  cut the delrin bars to the appropriate lengths (for 40cm omni spread, custom PAS @ 30mm, DINA/ORTF), of course figuring for the length of the SGC clips/capsules...
Step 2) drill holes in the ends of the delrin bars using a drill press to accomodate 1.5" 3/16 18 threaded ends... "tap handle" ends i bought from ebay. 
Step 3) simply screw the threaded ends into the delrin, didn't even need glue for this
Step 4) add a pair or two of rubber washers, found some at HD that were exactly 20mm, this allows you to get the SGC clips screwed in just right so they can be lined up properly in terms of twisting them consistently
Step 5) add the SGC clips to the threaded ends and you're done. 

They came out looking really great, they are continuous from the delrin to the SGC clips, can't see the screw.  Super durable and fit into any 20mm shockmount.  The only potential negative is that they aren't feather-light.

Will post pics of the finished product at some point, but here are the parts:

3/8-16 threaded ends:

Delrin bars (looks like the seller only currently has shorter lengths, but i would contact him, he has tons of this stuff)

I have been experimenting with my DIY PAS bar with PVC pipe and this is what I want to do. I definitely want to use Delrin! No painting or sanding needed And will DEFINITELY last a lifetime!!!

Just one question: The SGC Clips are 3/8", and you listed bolts that are 5/16" Is just the larger tap end the 5/16" diameter, and the smaller screw end 3/8" Thanks in advance, as Id like to order this stuff ASAP I owe Tonedeaf one and Id like it o be as bulletproof as possible

Sorry Bean, i posted incorrectly, thanks very much for pointing it out. In my haste i posted the wrong tap handle screes originally...yes they make them in 3/8....and they fit the SGC clips just exactly perfect...I modified my original post and here are the correct ones: http://pages.ebay.com/link/?nav=item.view&alt=web&id=261755397268
Thanks!

That's another great idea !!  Thanks for posting Chk !!!

I just went to Home Depot and bought 3' of SS 3/8" rod, so I'm covered either way That way I can make the threaded ends any length I want! And I should get my 4 1/4" Delrin from the guy you posted by Wednesday CHK!!! I'm going to order 3' of 20mm delrin from someone on ebay so that I can make a few of these for some friends

Thanks a BUNCH for the idea of using delrin! I always wanted to use delrin from the get go, but I remember Brian aka it goes to 11 saying that 20mm delrin was expensive! If I had known its only about $8/foot, I would've definitely started with it instead of PVC pipe, since sanding down PVC to 20mm isnt much fun lol I'll snap some pics when I'm done!

Really psyched to start this Thanks for the ideas Ian and CHK

Here's a few pictures of my first finished DIY PAS bar Im happy to put my name on this one lol! Thanks to Archival Audio for the idea, and to chk for the delrin idea and link I love it, although, like chk said, its not exactly lightweight. But it doesn't affect me at all since my rigs are very compact, so I think I can deal with a few extra ounces in my bag

Please let me know what you think! And BTW, the spacing on the bar is 17cm, same as DINa and ORTF Id be glad to make a few for some other tapers if you're interested

I had posted this in Bean's thread but thought I should post here too as Archival Audio and chk were the big inspiration for this project.
Basically, I took two of NBob's 2" Delrin risers and put them back to back. In the first pic there is just a piece of gaff tape holding them together but all I need to get is a small 3/8" stud to mate them. Add the SGC clips and POW!, just like yours! The second pic shows the DIY PAS bar next to my DIN bar ItGoesToEleven made.
I've got four 1" risers that I could add to it if I wanted to space it wider.
Ingenuity at its finest!

Here's a few pictures of mine too! Thanks a bunch for the ideas ArchivalAudio and chk!

Thanks to all for your postings on this topic and for all of the great pics and ideas. 

I did purchase a pair of Nbob 20mm SGC clips last year.  I like the idea of mating these clips to a black, threaded delrin bar for a DIN/DINa solution for my VM44-Links.  Are there any machinists out there that would be willing to thread the delrin rods for me for a fee if I provided the delrin rods to you for a DIN and a DINa bar?

[bluelawn]

can't help with the machining, but heres a quick sketch i made to have mine made 5.5 years ago. bribed the machinist at work, he made me 2 out of aluminum. unfortunately i've already given the spare away. set-ups still working great

I like the idea of mating these clips to a black, threaded delrin bar for a DIN/DINa solution for my VM44-Links.

FWIW, this is the setup I used for my old Naks and now am using for my VM44-Links:  http://taperssection.com/index.php?topic=144397.msg1860215#msg1860215

I just use the stock VM-44 Link clips on the ends, rather than the ones you see in the pictures.

Thanks for the posts.  Brian I ordered a few of the extension tubes and the hardware needed to attach the Nbob 20mm SGC clips to those tubes.
