OMG this is getting pretty frustrating. I seen on another post that the guy uses hot glue so I have tryed and tryed and all it does is break off when I go to stretch the fleece. I got tired and liquid nailsed the dowels and still broke off when stretching the fleece. What am I missing here, what is the best way to get the dowels to stick to the wood and the mdf without breaking!? Quick response is greatly appreciated as I am trying to do this right now. lol. Thanks guys!

how thick is the dowel you are using? Is the dowel breaking or is it coming undone where it attaches to the wood? I drilled holes through the wood i was mounting mine to and super glued them into place with regular super glue. Make sure you let whatever you use cure properly before you stretch the fleece over it. Even with super glue, wait atleast an hour. If you're using a two part epoxy glue or something similar read the instructions before you use it to see how long it takes to cure. If all else fails then go buy some JB weld and let it cure overnight.

no the dowels aren't breaking, they are coming off where the hot glue and where the liquid nails was used

What kind of fleece material are you using? Is it really rough or hard to stretch? I would use something not so difficult or something really flexible along the lines of "panty hose" type material. And yea, let it completely cure; whatever glue type product you are using. Also, like sawhit mentioned, create the pothole effect, by drilling in a few millimeters to allow the dowel to have a way to anchor itself down for added support and strength. ------------- I have not failed. I've just found 10,000 ways that won't work.

yup I actually got smart and tryed something else and I finished stretching the material but the damne speaker mount moved and caused it to hit the seat when the door was closed. When I tryed to fix it the dowels collapsed from the mdf ring and the FG door panel.

What did you try that allowed it to work? Got shots? ------------- I have not failed. I've just found 10,000 ways that won't work.

I tryed uding the hot glue in a different way that ended up holding it better. Right now what I did was drill the holes as sawhit4 said and I filled the holes with hot glue and put a couple of nails to anchor the dowels into the mdf, not sure how it is gonna hold on the FG though as that is where it ends up coming off first. Lemme snap some shots quick should have them up in about 5-10 min

i cant belive liquid nails didnt hold. Must have been something wrong with it. Like maybe someone on the fiberglass that wouldn't allow it to cure. I used that stuff to glue a box together once, but then had to knock out a wall of the box to redo it. I first tried a regular hammer but it wouldn't budge, so i got a 3 pound sledge and gave it a good wack. It knocked a hammer shaped hole in the box after a few hits. I ended up having to cut the side out. But i allowed it to cure for two days before i touched it, so that was probably it. Good luck with it this time. You're project looks sick. I cant wait to see it done.

haha yea thx I actually got it to work didnt collapse, BUT it did move a lil bit which is now causing clearence issues. The mount hits the seat and need to be moved over. (on the top picture it needs to move toward the wall) Other than that the fleece is stretched and if you check my other post 8W6 door panel project you can see the amount of volume I need. I will be using rice to measure the volume, went and bought 50 lbs. yesterday!! lol I had people looking at me like WT* is he doing!??? lol it was classic! Anyways I am done with this thread unless some other people have good ways on getting dowels and that to stick without movement. To be updated on my project please check out this thread.

you have to let the glue dry first...LOL but honestly...you dowels are too vertical....put them at slight angles to the ring...cause it is not the force of you trying to pull the fabric down that is causing it break free it is the force from side to side as you try to wrap the fabric that is breaking the glue...set the dowels up like a tri-pod as opposed to a hydropole and you will be much better off...if this dosent work use thinner more stretchy material, it is a door pod correct, you should be using panty hose for your initial stretch then... i am still not sure why every one wants to add boat loads of weight to the project by using fleece, or some other heavy material...it does look like your using a grill cloth of some sort though...but you still may want to try pantyhose anyway...that is what i pretty much build everyone on my pods with, and if i can usse it on a box i will too...best material out there...you hardly have to glue it, it is light as air, and serves its purpose.. and typically the dowels are broken out after the first layer or two of resin has cured, so drilling "divots" into the panels is not really the best idea in my opinion.also i would have used much thinner dowels those things look like they are 1/2" thick.. ------------- Fiberglass Guru.

Nice work around, glad you got it to work. Keep up posted, don't forget to take shots of it as you glass. ------------- I have not failed. I've just found 10,000 ways that won't work.
