Although I’d never, ever, heard about the Rhosgobel Rabbit :(, I absolutely LOVE your design. I honestly think it’s beautiful but…… it’s far too large and I want it to be sturdy and light at the same time; that’s the reason (1) I want to make it from Stainless Steel -don't have thick enough titanium- and (2) I had to make my own drawings (design). When I started the first drawings, I got carried away and already made 5. The last one, which at the moment is the lightest (in theory – probably less than 10gr = 0.35oz.), is this:
PS – I did read the link you added and the first thing that draw my attention was the “Schipperke”; it’s a very long time ago I saw this breed, native from Holland/Belgium (well, in reality, it’s Vlaanderen – the Flemish region of both countries) for the last time. I left my country 30 years ago and have not been back often.
I don’t think anyone can make a custom-made pot lifter (or anything else) without having the pot as well. At least if you want it to be of “perfect fit”, which is what I would demand.
As I wrote before, once I’ve made my version I’ll post some pictures. If you really like it, you might want to send me an email and I’ll see what I can do for you.Apr 5, 2013 at 7:30 am #1973054
I realize it wouldn't be a perfect fit. I'm using a Foster's can over a windscreen enclosed fire, and I need a way to get the can off of the fire without burning my fingers. The Vargo lifter works well, but it is over an inch wide.Apr 5, 2013 at 7:33 am #1973055Apr 5, 2013 at 8:27 am #1973081
Now I understand why you want to have a new pot lifter :) – apart from the Vargo being an inch wide, it’s heavy as well (0.8oz). Made out of Titanium??? Must be really BIG. Mine would be much smaller; as I said before, I want it to fit inside my BPL 550SUL Firelite Cookpot – therefore it can’t be longer than ≈ 8cms (just over 3”).
This was one of my first iterations; would that appeal more to you???? :)
The problem is the weight; the total superficial area would be about 2400mm2, which would mean over 11gr where the last version would be about 2050mm2: "only" 9,5gr :). The holes inside "save" about 0,7gr which isn't much, so I don't know whether it's worthwhile.Apr 5, 2013 at 8:34 am #1973084
Looks Good!! How heavy?Apr 5, 2013 at 11:39 am #1973121
At the same time (09:34) you posted the question about the weight, I edited my previous post and added these. The only thing that’s not taken into consideration is the 0,?? gram for the “rivet”. Once I’ve finished mine, I’ll have exact figures, but I wouldn’t like to keep using Bill’s post for “private” conversations. BTW- I will post the pictures ,as promised, once mine is finished.Apr 5, 2013 at 11:51 am #1973126

Stainless steel wire bail, about 6-8 inches long.
Newton suggests titanium fishing wire.

Hi Henk and others,
I don't mind you posting about your Pot Lifter on this thread. I think this is a good place for it.
When I made that Pot Lifter it was for the big red Trangia Pot that is shown in the first group of pictures at the beginning of the thread. The Pot is somewhere between 1.5 and 1.75 liters. It is used as my snow melting Pot and gets heavy at times.
The Pot Lifter might be large for a smaller Pot but still only weighs 13.3 grams or 0.47 ounces. I have some 0.016" titanium that might make a Pot Lifter like this one weigh about half that of the aluminum one.
The nice thing about being able to "Make Your Own Gear" is making things to "just" the size necessary for what it is used for. Lager Pot Lifter for a larger Pot or a smaller Pot Lifter for a smaller Pot. I have a bunch of different size Pot Lifters.
Henk, I like your newest design but I also liked your first one. When I was playing with my paper patterns I noticed a resemblance to a rabbit profile. I liked that so much I just never changed it.
It makes me smile every time I look at it.Apr 5, 2013 at 2:41 pm #1973185
This is my latest design; I think it’s going to stay like this. Having said so, once I leave theory and start with practice, I never know what I end up with :(
After some minor “shavings” and “drilling” the holes in the previous design, the superficial area becomes 2117mm2 so the theoretical weight would be 9,84gr. Adding the “rivet” makes it around 10 gram (0.35oz).Apr 10, 2013 at 4:29 am #1974773
I tried to send you a message but I can’t because you haven’t enabled an email address. Please send me a PM – you can find the address in my profile.

With Bill's permission, here's my version of his design:
Another picture with the length (it's really small):
The pot grip "in action":
The TFD pot lifter together with the rest of my "kitchen system" (for reference – the spork is a Lite My Fire Little):
As I said, it's really small and that makes it very light as well: 7,9gr (0.12oz) (Edit: WRONG – as I explain in the next post, 7.9gr = 0.28oz NOT 0.12oz). It does a good job at lifting my small pot (BPL SUL 550 Ti) with half a liter of water, but a larger pot with more water would be a different matter.
Hope you like it.May 15, 2013 at 1:23 pm #1986408
That looks outstanding! When can I buy one?May 15, 2013 at 3:35 pm #1986467
I made a mistake with the weights I mentioned earlier in my post. Being Dutch, although living in Spain, I think in grams and when I converted these in ounces I trusted my memory – bad thing when one gets old :(. The weight of my TFD Pot Lifter is indeed 7,9 grams, but that is NOT 0.12oz. It's 0.28oz.
The reason I made this mistake was because I'd calculated how much a titanium version of my prototype with a thickness of 0.4mm (0,0157") would be.
A) The weight of my lifter -without the rivet- is 7.9-0.1=7.8gr and the weight of the material I used being 37.7201gr/100cm2, makes the superficial area of the lifter: 7.8/37.7201=20.678cm2.
B) The specific weight of titanium is 4,507 kg/m3 (= 4.507 g/cm3), thus…… a titanium version (at a thickness of 0,4mm) would have a volume of 20.678×0.04=0.827cm3, which would give me a weight of 4.507×0.827= 3.7278grams. Adding the rivet back makes a total of ≈3.83gr and that works out to be the ≈0.12oz I mentioned earlier.
Sorry for the inconvenience.May 15, 2013 at 5:12 pm #1986534

You did a great job on your Pot Lifter.
This demonstrates how being able to make some of your own gear helps lower your pack weight and now you have a tool made for the job it is being used for.May 15, 2013 at 7:09 pm #1986573

Yeah, I agree with Bill – you have something YOU made that works great for YOU!
Feels good to do that.
I have to give it a go.May 15, 2013 at 9:38 pm #1986626

"Newton suggests titanium fishing wire."
I used stainless steel leader wire…
…for my bail.
I sourced the wire from Academy's fishing "department".
I'm partial to rabbits and I really like the look of yours. ;-)

I doubt that Ti is available as a 'fishing wire'. Try Ti welding wire instead – that is available. Also SS welding wire is very available. (Yes, I use both.)
Pot lifters: remember that Al is about 1/2 the density of Ti. This means you can use Al sheet twice as thick as the Ti for the same weight. What is not expected is that it may well prove stiffer (more stiff) than the thinner Ti. This is because the thickness of the metal turns out to be extremely significant.
