Femtrooper Julie[501st] Posted September 23, 2011 Report Share Posted September 23, 2011 Ok, call me crazy, but I was thinking of ordering a real sterling spring set for a doopydoos resin build. Looks like they are only $20, what do you all think? http://reocities.com/Pentagon/barracks/5220/SAPriceList.htm Quote Link to comment Share on other sites More sharing options...
ZeroRoom[TK] Posted September 23, 2011 Report Share Posted September 23, 2011 If the doopy doo's ID allows for it I say do it for sure! Quote Link to comment Share on other sites More sharing options...
MartinSivertsen[501st] Posted September 23, 2011 Report Share Posted September 23, 2011 The inner diameter of the doopydoo full resin kit is 22mm, and that is significantly smaller than an original i believe, so an original spring might be too big to fit inside the doopydoo pipe.

ZeroRoom[TK] Posted September 23, 2011 Report Share Posted September 23, 2011 So the wall thickness of the doopy doo's kit is 15mm? That's huge! Quote Link to comment Share on other sites More sharing options...
Shooter Posted September 23, 2011 Report Share Posted September 23, 2011 That is interesting feedback, I was thinking of doing the same thing for my ESB PVC build. I had no idea the inner diameter was different. Anyone know of any alternatives that would work? Quote Link to comment Share on other sites More sharing options...
ZeroRoom[TK] Posted September 23, 2011 Report Share Posted September 23, 2011 Most PVC pipe has a 2-3pm wall thickness so it should be ok. The biggest part of the sterling 'guts' is the bolt which is 33mm OD so it should be fine for a PVC tube. sskunky just posted full dims for the spring set up in the sterling templates thread we've got going (can't post URL because I'm on my phone right now) but check and compare.

3phase Posted September 23, 2011 Report Share Posted September 23, 2011 (edited) Springs are easy to do your self. Get some wire the thickness you like and wind it around a broom handle or similar that will give you the desired radius. Heres mine I did for a PVC E11 I did.

ZacMuleer[TK] Posted September 25, 2011 Report Share Posted September 25, 2011 (edited) I have a great method for the doopydoos resin kit- I bought a 5/8" (I think the measurement is correct: I'll double check) dowel rod from lowes and a roll of 14 gauge wire (near the picture hangar aisle from lowes as well). The wire easily wraps around the dowel and keeps it's form (but does not act like a real spring). It's also a perfect fit into the doopydoos full resin kit. EDIT: pictures added.
