Aimlesspayload Posted January 16, 2009 Posted January 16, 2009 I ordered a 3" HDPE mortar online. The supplier is currently out of HDPE mortars, but is offering a 3" fiberglass mortar as a replacement. Fair trade? Are fiberglass mortars as safe/durable as HDPE mortars? -Thanks for any replies. (By the way, I was unsure if this should go in the pyrotechncs or safety section)
FrankRizzo Posted January 16, 2009 Posted January 16, 2009 HDPE is a better mortar material in my opinion. Who is the vendor? That will tell us a bit more about the quality of the original HDPE ordered.

crazyboy25 Posted January 17, 2009 Posted January 17, 2009 (edited) I have only used HDPE I don't know if fiberglass is as good. Try Kastner they always have good stuff. Edited January 17, 2009 by crazyboy25
tentacles Posted January 17, 2009 Posted January 17, 2009 Isn't he a reseller of the pyrogear.net guns? I'd check with Noel over at pyrogear, he's a great fellow. If you're a passfire member there is a discount available.

tentacles Posted January 17, 2009 Posted January 17, 2009 (edited) FWIW, I've heard fiberglass guns lose nearly half their strength after 10 consecutive shots, no idea of the truth of the matter there, though. The number is probably less for smaller guns; my 1 7/8" FG gun is rock hard, can't imagine those little shells shattering the fibers. Likely the strength loss is due to the gun heating up and the fiberglass resin/epoxy becoming soft and pliable, thus the gun loses much of it's strength.. Edited January 17, 2009 by tentacles
Mumbles Posted January 17, 2009 Posted January 17, 2009 I thought that was 10 repetitive firings. Like you fire 10 in a row and the gun starts to loose strength. I just thought I'd clarify, as it makes it seem like you meant 10 shots period. Any professional shooters or pyro club will disprove the 10 total firings. My vote tends to go with HDPE too. It's not as light, but I feel safer with it. I've actually heard that multibreak shells are better out of fiberglass due to the one piece construction. Buried into the ground of course.
tentacles Posted January 17, 2009 Posted January 17, 2009 You're right, mumbles, I'll edit that post to reflect that correction.
Miech Posted January 17, 2009 Posted January 17, 2009 I rather use fiberglass mortars. I've never seen one break or shatter, exept the time someone put a salute upside down in it. Good quality HDPE mortars having the right ID are quite hard to obtain where I live.
FREAKYDUTCHMEN Posted January 17, 2009 Posted January 17, 2009 (edited) Shooting 6 pound 6" cannister with fiberglass mortars without any problems. I'd be glad getting a 3" fiberglass mortar for 7 bucks. Edited January 17, 2009 by FREAKYDUTCHMEN
ST1DinOH Posted January 18, 2009 Posted January 18, 2009 (edited) fiberglass is almost always cheaper than HDPE. so he's definatley getting over on you for at least a few bucks, but HDPE is the superior gun to use. i'd either tell him to wait till it's in stock, or get your money back and deal direct with pyrogear. noel is a standup guy, you can't go wrong ordering from him.
