What is Best to Glue Coil Housing Together

[geoscash1]

After doing a bunch of searches and not finding a real good answer I thought maybe a new thread would be a good way to see what everyone uses to glue their
coil shells together with, seems to be a subject that is overlooked or maybe not important to most, not to sure since I'm not seeing much about it.

1) What do you use to glue/seal your coil shells?

2) What were your results?

3) Is it waterproof?

4) What have you tried that doesn't work?

5) Pictures are worth a thousand words, post them if you have them.


Thanks in advance

in any PVC tubes shop youl easely find out a PVC glue. the tubes it using are of white - cold - water and grey - hot - water.
in any garden aroundany where you have to see them because for used water drench mainly.

epoxy resin works on most plastics but not nylon

polyester resin does not stick very well

[kt315]

epoxy resin does not dissolve ABSand PVC plastic. it is bad be cause you l not get a good dependability. you have to use something that dissolve -
that is THE RULE.

ethyl acetate, methyl acetate, dichloroethane

For ABS offcuts of material dissolved in MEK.

The Most Important Question: For Which Plastic Material?.

The Most Important Question: For Which Plastic Material?.

Well Gary, As far as I know, most after market coil housings (dbowers, ebay and others) are made of ABS so I assumed that's what most use or will be using.

As far as my original post, I was asking what you all use personally, your process and if it worked well or didn't work well. I am just trying different things
because I want to make sure I have a solid waterproof seal. I have used ABS glue, marine goop glue and poly resin epoxies previously and like the slower setting of
the marine goop as compared to the ABS glue.


Thanks for the replies so far.. Still looking to see some of what you all have used and how it worked and how you applied it to the coil housing itself, this thread can be used for later reference and others with similar questions. please post pics if you have them.

if you are in USA (I believe) so you have to be looking over around USA made glue, be cause best quality.
pics say more. I used it much years ago.

Hi. I just made my first coil. It's 12mm plywood. The coils are 40 winds, 6 1/2 inch dia. .25mm enamelled. I used Exterior PVA(Aquadhere) for setting the coils( a bit of supa-glue to position).
The shielding I used was mylar(I think) powdered milk bags. I tried sticking that with PVA to no avail. But the resultant seal of PVA on wood made an excellent base for the Chloroprene glue I used for the mylar.
I don't know if this is any help for plastic housings, but may be helpful to someone.
Adhesive silicone would fair well for joining plastic housings, as it would be more jar-proof and less prone to splitting if jarred sharply, I think.
I am still trying to work out how to upload photos-where's the manage uploads?

Thanks 6666, got it now. This is my first dd coil. I will attempt to make a cover from the thin plastic cutting board. Hopefully it will melt before the rest of the coil...

[Tim]

Well the plastic cutting board has potential. I tried making this one in the oven(200C). I laid it on a tray. First without baking paper underneath,whoops! then this attempt. When I get a heat gun I will have another go. I wasn't game to put the whole coil in the oven for fear of melting the enamel.(?) By heating and smoothing each area I should be able to get a respectable shape and finish.

[Tim]

This is super-slick stuff, so I can't imagine what glue would stick it ?? Any ideas?

I fail to understand why more people don't employ the technique used in "Inside the METAL DETECTOR" from Chapter 10 - IB Coil Experiments.
This allows you to use any cheap coil cover to make a good looking and functional coil relatively easily.
