Should you have one, how can I order it and how much does it cost? Thanks for your help. Signed, Gerry Guy. Hi Gerry Guy Thanks for your question. It may not be what you want to hear. As you know, the cartridge style used for Hank Roberts, Gerry and similar stoves has been out of production for many years now. The Hank Roberts and Gerry branded stoves have gone the way of 8-track tape players, Sony Betamax VCRs, and crystal radio sets — they are outmoded and obsolete, having been replaced by much better modern alternatives.
On the other hand, I do understand that some people enjoy collecting these old dinosaurs. Heck, I have a few of them myself! I did a small run of custom-machined adapters for Hank Roberts conversions back in for some fans of this budget-priced stove of yore.
I no longer have any in stock. There is no one anywhere else in the world that I know of that does any sort of conversions for these. So, there is no need to knock yourself out searching the web further. All this said… most people including me! Modern lightweight backpacking stoves are designed to specifically burn the gas mixtures in present day isobutane cartridges.
Hank Roberts and Gerrys, on the other hand, were designed to burn straight butane. Isobutane works much better in cold conditions and comes in canisters you can find all over.
And… if you are looking for even cheaper, but still usable stove alternatives, there are many, many imported isobutane stoves coming out of China and Korea that are really quite good.
Or, you can make a nice display of vintage backpacking gear in your home to remember those great old times on the trail. I still have my old Kelty frame pack hanging on my wall! I want to fix my old stove and I need to get the NRV out of the pump tube to replace the old rotten pip. I tried to buy one of those NRV wrenches from S. Can you tell me the dimensions of the NRV head, please? You bet.
Here are some photos. All measurements in millimeters. The dimensions are proper for the vast majority of NRVs in stoves out there. Be aware there are a few stove companies that vary from this style. Clean the cut to exact dimensions with a file. If you are more of a machinist, maybe have a vertical mill, you can use a 4mm end mill with two passes in your mill and make a closed end wrench like this:.
The closed-end wrench just above is an original Optimus wrench for marine stoves. I tried to make this one up from a bolt recently to fit into a specialty off-brand stove whose NRV head is down inside a pocket in the end of the pump tube. The failed example I show directly above is made from a too small diameter bolt. So, try to keep your bolt as large in diameter as you can to avoid the sides bending out like this. More material gives better support. I have a short question about the bernie dawg silencer caps.
Does the Omnifuel Cap fit to the Multifuel Burner? Sorry about that. This is a bit complicated, so please read through this carefully. Omnifuel The Trangia X2 Multifuel burner is made for Trangia by Primus, but it is made in a way so that it is not as powerful a burner as the Omnifuel.
This is also a very expensive burner for what it is. You can usually find used or even new Omnifuel stoves for less than the cost of the greatly overpriced X2.
For the reduced power Trangia X2 Multifuel burner, the PolarDawg silent damper cap works best using isobutane canisters and white gas due to the smaller jet supplied for those fuels. The DragonTamer is a pretty good second choice for these fuels.
Trangia makes it pretty clear in their product manual that isobutane canisters and white gas are the fuels of choice for this burner. If you intend to use kerosene with this burner I discourage this fuel for this burner , then the supplied same-size-as-the-Omnifuel 0. This turns the burner back into a simmer-disabled Omnifuel burner, so you should use the OmniDawg cap if you decide you absolutely must use kerosene. Some clever stove users have changed out the jets on their Trangia X2 Multifuel burners so that the X2 runs the same jets as the Omnifuel.
For example, using a 0. Using a 0. If you intend to do that, it may cause melting of your Trangia windscreen surrounds if you are not careful and attentive. But, using the more powerful jets makes the X2 more like the Omnifuel, and a OmniDawg cap would be the right one to use.
If you use a 0. I do not recommend the use of a re-jetted X2 with an OmniDawg cap with the Trangia 27 sets as the small size of the surrounds puts the surrounds too close to the flame. Trangia 25 sets are okay… if you are careful.
