my first BIG project. I am following the tutorial "How to make a fiberglass enclosure"     i never got a chance but here are some pics of my first project which is my tweeter pods. Anyone have any good ideas of what type of fleece to use and where i can get it from? I bought some cheap-o fabric from wal-mart and it is not tough enough for my staples and always has wrinkles no matter how hard i pull it. Tell me what ya'll think...

Use a light weight fleece...or polyester blend material. don't use cotton. I got mine from fabric.com cause i'm too lazy to find a fabric shop. Buy the cheapest they sell. Look at clearance section.

i say NEVER use fleece. always use speaker grill cloth, jersy material(what t-shirts are made from), or nylon(what stockings and pantyhose are made from) then reinforce the reverse side that wont be seen with matting. not only will the finished side look better with less sanding than using fleece and gallons of body filler, but for anything not cosmetic that needs to be strong, like a box, fleece will fold like cardboard. even if you reinforce it from the other side with matting, the resin used at first never soaks all the way through and even if it did, resin soaked fleece is way heavier and not near as strong as matting and resin. every thing ive ever seen using fleece turns out to be nothing but a BONDO covered gonna just crack later piece of crap, not fiberglass. might as well call boxes made with fleece "BONDO BOXES" not fiberglass boxes.

I use any material that is Poly whether it be fleece, cloth, or whatever. The key thing with fleece especially in hotter climates is that it tends to shrink more than the other bases during curing and may cause bending. As for it's strength, if done right, fleece can work. I have made many boxes from fleece and other structures that have been holding up for years now. Some of them are in SPL competitions and have yet to generate a crack. I would say the key to them is to ensure a strong frame and as soon as the resin gels, start cutting off the loose fibers that may stray and/or have a second person come right after you with a roller to keep them down before gel stage sets. Once cured, hit it with a quick wipe of acetone and sand with 60-80 paper. Duraglass any lips, then finish the project.

Reinforcement is always a +... You can never be too strong

The best thing to use would be grille cloth but it can be difficult to find. Me personally I like to work with pantyhose fabric some say you shouldnt do this but I use it all the time never had a problem and really the fabric doesnt need to be that strong it is only used to get the shape of your enclosure it wont really add any strenght to it thats what the actual fiberglass is for...

By the way nice build looks good so far

i would never use grill cloth. for one thing it's not always possible to get you glass behind the project at hand. i always use fleece polyester that would make sence because your useing polyester resin. don't pull your work tight. lay your fleece so all the wrinkles are out and then fasten it. i'm not saying lay it loose but don't force it  you go where you want it. you want it to "lay out" right with out being to tight but tight enough not to lose the shape your trying to achieve. to tight will cause your work to twist and warp while drying. there are also two sides of your fleece. one is very "harry" and one is kinda smooth so look for that when you start laying your fleece. most of the time it doesn't matter because your going mat the top any ways. your A pillers look great man!!!keep it up. and a little practice go's miles.

i used some thick *** fleece, so thick that when soaked with resin i would press in it with my finger and it would appear dry. it eventually hardened and came out decent i think. i only did like 1 layer of mat because i ran out of mat and resin (1 gallon) i am applying the mat by spraying the area to b fiberglassed with some spray adhesive and then laying the mat then stabbing with resin.
