I wanted to buy some 3/8" square nylon rods but then I noticed that they are $5.56 per foot which is just way too expensive for me. I wanted to know if acrylic or PVC also worked.

Edit: Thanks for all the comments, I decided to use delrin but I need to make 5 NF rifles so I'll try PVC for one of them. I'll tell you guys how it works out.

I was searching for foam but the shipping was crazy expensive since I live in Canada, then I found some PDF documents that mentioned Tundra Foam as the manufacturer. I went on the site then I realized that they are located in Ontario, Canada. I got really excited and I will contact them soon to see if they can sell foam in smaller quantities than 5000 feet (this was on their PDF catalog). I just wanted to share this for other Canadians so we don't have to pay so much for shipping. I will update this thread after I contact them, hopefully they can sell me some foam. If they only sell 5000 feet it will still be much cheaper than the price at Best Materials, I don't have any use for 5000 feet of foam so I would probably sell for the price I paid plus shipping. They also have the option to FBR with a custom profile and dimensions so we can have blanks with precise dimensions straight from the factory.
Thanks for reading, some of you probably already know this but I just wanted to share my discovery.

On Tuesday I will be heading down to Florida for about a month, this is a great opportunity to make some purchases from McMaster-Carr since they don't ship to Canada. I will be getting some [k26]'s but I am not sure what else to buy. What do you guys recommend for a reinforced catch spring? Please post anything that you think is useful from the site, I will not have enough space in the bags to buy piping or polycarb. I will not be making homemades (not yet) or terribly complex mods, the most complex my mods get is an angel breach Longshot or a Nightfinder rifle. Basically if you could not purchase from the site for a year, what would you stock up on?

Thanks

Sorry if this is in the wrong section, I'm not too familiar with the site yet.
