I again have access to a range again so hopefully I don’t have to travel this year for work and can again do some experiments starting in Spring. Long story short in order to get needed velocity say from a 200gr bullet like the 200FTX I see no other option other than going with a duplex. For me I want to use a single vial with double compartments. For single loads I like the plastic vials that allows me to see the powder and that it is all emptied when poured. The point of the double compartment is to keep the whole load in one location instead of having 2-loose vials to deal with. Now this poly plastic doesn’t lend itself to gluing so I thought I would try fusing the ends with carefully placed heat from a soldering iron. Surprisingly it worked well and when I tried to flex it, it held together without breaking. With the use of this method there is a groove left behind from the pointed soldering iron that I don’t like having. I tried to produce an epoxy band around the joint but the epoxy ran and had to quickly clean it before it solidified. Okay no panic as this can be corrected by rotating the vial while the epoxy cures. Years ago I used to build fishing rods and after tying on the eyes the thread had to be coated with epoxy. For rotation I used to use a barbecue rotisserie motor and may have to build another that would be a nice winter project anyway. One way or the other I will have that epoxy band for additional support. Anyway I thought I would share my project and to where I’m at with it. Ed

Pretty Cool Ed...My first thought would be to sleeve it with some heat shrink tubing,but it wouldn't be see through....

I had this notion as well and was thinking of finding something to force down the vial a small way creating two compartments. Sounds like a project to me

I have been doing exactly what Ed has here for over 10 years. I take 2 of his larger vials and put them back to back. I secure them with a complete wrap off duct tape. Works awesome

I think my vials are polystyrene but not sure, yours look like polypropylene!
You can use a super glue BUT you need a primer or the connection is weak. Also the greater the surface area the better.
You might be able to use a heat gun and expand the small side but you need to do it from the cap end or it will probably "accordion" on you. Most thermoformed plastics have a lot of memory so it will try to shrink back to its normal size when reheated ( think shrink tubing ).

Thanks for your comments that have added some additional concepts for me to look at for future construction of dual compartment vials.

ET I used to do a similar. Process to repair nylon numbers on radio control race cars. However as I melted the bumper back together I fed in a black zip tie...just like if you were gas welding something ...with a rod. Try this with a clear or white nylon zip tie. I bet you can make the gap go away Drop

The reason I was trying to insert something into the vial to create two spaces was to try and avoid all this gluing and melting.
Watching this with interest.

Just a final note to this project as I have decided the path to take. First a thanks to 12ptdroptine as his comment triggered a thought for an approach. I remembered I also have a soldering gun with a flat tip attachment. So by carefully lowering the flat tip onto the joint and rotating the tube I sort of melted the plastic washing the plastic to a flatter contour. Not the prettiest but still neat and fully functional. I have to admit I did loose one vial because of poor centering and overheating from the flat tip in trying to get a decent contour. This one is also going to stir the pot with the old lady. Now the only thing to deal with is aftermath of the smell of burning plastic in the house. Women have an uncanny sense of smell and when the lady of the house returns from a show with her friend I know she will pick up on this activity. Guess I’ll have to resort to saying it was for a worthy cause. It might not totally get me out of the woods but at least the woods won’t be on fire burning hot. Ed

Good idea. The multiple vials are a factor to my use of a single powder. On a tangent multiple times this season I've had the tops come off my 10ml vials. I carry all the reloading components on my gun in a buttstock shell holder. I found two sst's on a trail today. I like the snap top design like the 5Ml's. Maybe I could put some thread tape to keep them from unscrewing during a trek?

Mid_Tn_Plowboy I can imagine the aggravation of caps coming undone especially while hunting. Not really sure how I would overcome that one. They do snug down good if they are started on right. For my application these vials fit perfect in the shell holders on my hunting vest. Never had a cap come loose and like the easy one hand access at chest height. These single size vials also house 2-sabots and bullets per vial. Even though I thought this vest was a little pricey at Gander Mountain I have no regrets on purchasing it. Ed

Maybe I'll wait until reaching my stand to put everything in the shell holder.

For what it’s worth to anyone I find you have to turn the vial or cap backwards until you get the deepest insertion of the vial into the cap. Then snug her down. I’ve never had a cap come loose this way.

I am just using my old Butler Creek blackpowder speedloaders that were divided into powder/ball with slip caps on each end. I have powder in one and sabot/209 in the other end. You could just as easily keep the sabot in your pocket and use that smaller compartment for the booster charge. They are not clear, but no powder is ever left in them when you dump it.

That would be another good concept to explore if you are starting out with duplex. In my case I have 100 single vials on hand where all don’t get used. Being a tinker at heart and like personalizing my equipment when possible I thought I would give it go making a duplex vial. It worked and I’m happy with 15-vials all ready to go to work. Ed

I tape two together; one pointing one way and one the other. I have also rubber banded them with success. I put powder in one and bullet, sabot and two primers in the other. You could easily fix these up as duplex containers.

I have used clear packaging tape.
