Crestworth lantern new bottle fit

[BLAKE EAST]

Hi, everyone.  This is my first post so be gentle and use lubricant. 

So to the point,  I've recently bought a new bottle from mathmos for a crestworth lantern.  Yippee. 

Problem! I know the bottle design changed sometime in the last decade with the added lip to the base of the bottle which is great for the current line up but sucks for the old war horses.

Mathmos's reply was a bit rubbish  with just square it up as best you can.

The obvious answer would be to put the liquid and wax from the new bottle into the old bottle, but to be honest I've never been a fan of tampering with the bottles. 

My question is this how do you solve this problem. 

I've looked into the vtie mouldable silicone rubber and I'm thinking  of putting a few small blobs on the bottle which will set with the bottle out of the lamp but give more purchase and hopefully solve the nodding bottle problem. 

Vtie is heatproof up to a point apparently. 

Another option is to use some small pieces of rolled up baking foil.

I'll post my results if the house doesn't burn down.

I mentioned the same issues when the new design bottles came out, its frigging pain and like you mathmos didnt get a good idea how to solve it.

If you go down the road of refilling the original bottle then the old bottle needs to be cleaned out, then while cold pour the fluid from the new bottle into the old bottle, then put the new bottle either on your lamp base and melt the wax completely or place in a pan of water and heat it up, once melt tilt both bottles together so you can slowly pour the hot wax into the old bottle, BUT you will notice a difference in contents level as new bottles have less so would have to top it up with distilled water.

Another option is maybe some of this stuff and put on the edge of the lantern Rubber U Channel Edging Trim find a very small width one and spray copper

Hey Johnny thanks for my 1st reply. 

I see what you're thinking.  I've not experimented yet but I ordered some vtie moulding silicone and I've already gone off the idea.

I'm  going to be pi**ed if it melts or catches fire and ruins a good condition crestworth lantern. 

I wonder if I could make or buy a steel or aluminium circular plate like a large washer or ring for the bottle to sit on.

It would sit inside the lamp holder being a smaller diameter than the top but not fall too low due to the lamp holder being conical. The bottle sits more square on the ring and also blocks it from view.

Hmmm to be continued me thinks

Mathmos did offer me a inner ring to sit in the base at the time, but i just refilled a original bottle from the contents of the new bottle design, i think a ring circle plate may be the best option

So here's what I've done. 

I used a few strips of copper tape on the base of the bottle,  North, South, East and West. 

This seems to have given the bottle a little more purchase cutting down the nodding problem. 

You can still push the bottle off of a square seating but it sits in place under it's own weight better than it did.

If you position it square then it stays put which is OK because I don't move the lamp much.

Bonus is that

1. You can remove the tape if need be.

2. You can't see it. 

3. It's metal and won't melt or burn.

4. It doesn't block the light or heat.

If I spend more time and carefully add more copper tape I think to would sit even better.

Low hassle solution. Ta daa.

When you finished it you have to put a photo etc and links on here as im sure theres plenty who have the same issue

Great tip, I'll keep that in mind if I find I have problems with a new bottle in our coach lantern in the future.
