Hot Glue Gun Question...

[VR3]

How fast does the glue dry once its hit the surface?

Thank you!

[RuSsMaN]

Read the box for set up times. Dork.

[VR3]

I dont have a gun... or a box...

I just need to know how much time I have when its all on the mdf, and how much time before its to hard to put something on it and not have a good bond...

Something a box probally isnt going to tell me...

[janmike]

Any of the ones I have seen was a matter of seconds (10 -15). See if you can demo one. A lot of companies will have certain tools on display that you can test.

[DarqueKnight]

The packaging on the hot glue that I use says it sets in 30-60 seconds. The variance in setting time depends on the temperature of the glue gun used.

[BlueMDPicker]

That's been my experience as well. It does tend to start "skinning over" in about 2/3 that time, and loses tack in the process.

[VR3]

What if....

I had a hair dryer blowing on it from an angle...?

Would this allow more time?

This is looking trickier and trickier...but I think it'll be well worth it...

[BlueMDPicker]

Give us some insight into just what it is you're bonding, please.

[VR3]

Here is what I am trying to do...

Im trying to glue THIS port... in THIS spot... (after the panel is already on there)...

If I glue it on before the panel is on there - I risk the port not being at a 90 degree angle... and I also risk the glue causing the panel to not fit...

[VR3]

a little different perspective...

[brettw22]

Are you cutting holes at each end of that port?

I'd say use Gorilla Glue or something like that to set something el permanente......

[VR3]

yes...

The panel under there isnt attached - its just laying where it will be...

It is abot 3" from the other panel... just one hole.

Hmm... gorilla glue... I will have to look in to that one - would regular wood glue work as well?

Unless the port is wood / wood glue wouldn't work well. I think Brett's idea of Gorilla glue is best, any home store.

[VR3]

What if I made a port out of wood on the lathe?? ;)

That would be so cool.... lol

You could even make it... FLARED!

Will take a looksy at Gorilla glue - I'm headed to HD today with my handy gift card!

Thanks for all yalls help! Mucho preciated!

[michael_w]

You could try some kind of epoxy... it'll stick to practically anything and give you more time than hot glue. (without the burns assoicated with those damn things too ;) )

[unc2701]

Hot glue will peel off of many surfaces... not at all good for permanent bonding. Get gorilla glue.

[VR3]

I just bought a hot glue gun...

For a few reasons...

1) It was insanely cheap... lol
2) I found a gun that was rediculously small that would make what I want to do incredibly easy... so why not...

The reason why I wanted to use a hot glue gun - thats how I've always seen ports glued to the MDF in OEM designs...

If that dont work...I may have to anty up for the gorilla glue. But you dont get alot of glue for the money, thats for sure.

I plan to tack glue it in place (all where it touches wood to prevent rattles, of course), then just fill in the rest with caulk...

[scottnbnj]

hot melt is probably best suited to glue it while it's in place, rather than apply the glue then slide it in. some glue guns have long tip attachments that allow you to get in to tight spots. some of the slowest setting hot glues i've found are in crafts stores, moreso than in hardware or home improvement depots.

maybe a little dab of gorilla just on the contact points before sliding it in, then fill the voids with hot melt after it's in place. that might give you the advantages of each glue and they would help correct each other's weaknesses.

Liquid Nails would be better suited for that job.

Gorilla Glue is crapola.

[unc2701]

Good call on the liquid nails- just don't get it on anything that you care about. I was doing some stuff out on the driveway, the liquid nails dried on, and it actually pulled up a chunk of concrete when I tried to chisel it off.

Put another way- if I had to cut a house in half, I'd use a sawzall; if I had to put it back together, I'd use liquid nails.

[scottnbnj]

yup, liquid nails or pl-400 type construction adhesives would be a good bit stronger than poly and hot melt, but might be a bit messy for sid.

i'm not in the poly-glue is crap camp.

[VR3]

Yes, I am fully aware of what liquid nails are capable of... hehe

We glued a post to a brick step because we couldnt mount it due to the concrete...

Thing has been there... 4 years now... lol

[steveinaz]

Liquid Nails would be better suited for that job.

Gorilla Glue is crapola.

YES. +1

[HiPerf360]

Liqid nails dose not adhere to some plastics though, try it first.

[Skynut]

EPOXY


two parts go in, one part comes out.


There can be only one.

[burdette]

F1, I'm not sure what troubles you've had, but I will 4th or 5th or wherever we're at on Gorilla Glue. Good stuff. You don't need to use very much, though (and don't forget the water... i.e. read the directions). I used Gorilla Glue extensively for the construction of the 10ft^3 box I made for an 18" sub, including the installation of the port.

I think Liquid Nails would also probably work... you might want to score the outside of the port a little bit.

I would NOT use hot glue, especially on that PVC. It might seem to bond, but I betcha you could pick it right off

[VR3]

Well... my situation is a bit different than your average port mounting... lol

In my situation, as you can see in the thread - I have two "supports" on two sides of the port (four total) --- and I am gluing it directly to those supports, PLUS the panel itself... + sealing it... so it is in there very strongly...

[dkg999]

Sid - what you see on new speaker construction that looks like hot melt glue is not. What it is is UV light curing production glue. It is what was also used on the older Polk monitor series. They slap the glue on the parts going down the production line, then hit it with something that looks like a black light, and presto the glue is cured and they can move on to the next assembly step. Production cabinet shops also use this kind of glue. Hot melt glue is a very bad choice for anything you want to be glued permanently! I would use the Gorilla Glue suggestion, or go with a good silicone seal glue.

[doggie750]

Silicone II by GE from Home DEPOT will do........

[Airplay355]

You know you're a redneck when....

You use liquid nails to glue a post to a brick. :)

Duct tape 'ill fix 'er up real good now.
