Scales bear with me and I'll try to find out where I got the acrylic and the needle valve. The needle valve came from a place just off 1st ave in Burnaby, almost at Gilmore. The acrylic tube came from a place over by the coke dist center under the port mann bridge. Sorry I can't remember names.

I don't have any acrylic left, I made a bunch of bubble counters and other stuff. I think the length was $10 maybe less, the 4" stuff was $60 for 6 feet. Larger stuff is harder to get, this place told me that you can only get larger diameter acrylic in cast which makes the price increase about 4 or 5 fold (IE 6feet for $300).

Thanks for your help.

If you remember the names, particularly the acrylic place, let me know.

Cheers.

Trevor

Sorry I took so long, here you go.
Acrylic tubing was from GE Polymer shapes (604) 468-2112
Needle valve was from Peerless engineering (604) 659 4100 PN KLN230B

I am using a flow regulator instead of a Pressure regulator on mine. I still use a bubble counter though.
