Great strides are made yesteryear non bad men. In the globe of modern pack stoves, ane human being stands out: Mr. Larry Penberthy, founder of MSR. Larry Penberthy (March 11, 1916 - Nov 24, 2001) was an iconoclastic genius.
Behold his creation: what is straight off known equally the MSR XGK stove:
Penberthy observed that ane of the leading contributers to the mutual frigidness conditions killer, hypothermia, was dehydration. Why were mountaineers getting dehydrated? When all the globe about yous is cold, hard, in addition to white, H2O is tough to come upward by. The stoves of the twenty-four hours were largely tank mounted brass stoves, beautiful works of fine art yet cherished to this day, but hardly light. Many mountaineers, unwilling to pack their excessive weight faced dehydration instead, risking hypothermia. Penberthy, a mountaineer himself in addition to a origin charge per unit of measurement engineer, laid out to pattern a stove. He noticed that climbers of the twenty-four hours tended to deport spare fuel inward Sigg aluminum fuel bottles. Why, he reasoned, should people deport inward termination 2 fuel tanks (one equally share of the stove in addition to ane inward the shape of the Sigg bottle)? He designed a see that would screw into a Sigg fuel bottle, turning the bottle into a pressurized fuel tank capable of delivering fuel to a burner. His stove, straight off no longer sitting on top of a fuel tank was lower to the ground, making it relatively stable in addition to bringing it downwards out of the wind. He in addition to thence added a canvass of about 6" x 31" heavy aluminum foil equally a windscreen. On stoves where the tank was straight attached to the burner, a windscreen of Penberthy's pattern could trap besides much rut in addition to movement the fuel tank to explode. On this novel type of stove where the fuel tank was separate, a windscreen could live safely used. Today, nosotros hold back at things similar a fuel bottle used equally a fuel tank amongst the fuel good away from the burner in addition to an aluminum windscreen equally obvious. Let us non forget that it took a visionary similar Penberthy to come upward up amongst something thence uncomplicated in addition to yet thence effective.
He also made his stove champaign maintainable: The jet could live unscrewed for cleaning or replacement amongst a uncomplicated slot caput screwdriver. He added a cable that ran downwards the fuel draw that could live used to scour out carbon deposits. Penberthy made the stove company equally though his life depended on it -- for inward fact his life did. Penberthy climbed using his ain inventions. Penberthy designed non alone his brilliantly innovative stove but also H2O ice axes, helmets, in addition to other climbing equipment. When taken equally a trunk of work, his genius is clearly seen.
Penberthy's stove pattern revolutionized climbing stoves, providing a relatively calorie-free weight, relatively current of air proof, effective stove, a stove that climbers were non alone willing but glad to carry. Sadly perhaps, Mr. Penberthy's pattern may cause got contributed to the demise of the classic brass pack stove. Penberthy's origin production stove was the Model 9. The Model nine was a white gasoline alone stove. The Model nine was in addition to thence joined yesteryear the "MF," a multi-fuel stove. Later, the Model nine became the G (gasoline) stove, in addition to the MF became the GK (gasoline/kerosene) stove. Later still, the G in addition to GK stoves were merged into ane stove, the XGK. It is yesteryear the moniker "XGK" that this draw of stoves is to a greater extent than oft than non known. The XGK was supplanted yesteryear a somewhat redesigned XGK II which dropped the wire curlicue about the generator, removed the surge dampener, eliminated the flintstone ignition, in addition to did away amongst the aluminum loving cup which used to come upward amongst the XGK. The XGK II had 3 versions: the origin without a shaker jet, the minute amongst a self cleaning "shaker" jet, in addition to the 3rd also amongst a shaker jet, a redesigned spreader plate, in addition to a novel "X" type of removable pot support. Eventually, the XGK II was replaced yesteryear today's XGK EX.
To this day, many a mountaineer swears yesteryear the XGK. In mutual frigidness weather, the efficient, powerful XGK is the snowfall melting stove of choice. Recently, I noted amongst involvement some photos on a polar explorer's spider web page. The stove inward the photos? The MSR XGK. Influenza A virus subtype H5N1 yr or thence ago, I had an MSR XGK on the tabular array inward front end of me at a Sierra Club function. One of the members, a serious climber, remarked, "on Aconcagua, that was the alone stove that worked." Aconcagua (22,841 ft/6962 m) is the highest dot inward the Western Hemisphere.
It is alone plumbing fixtures that inward my serial on wintertime capable stoves that the XGK live included.
This week's stove is the origin of the XGK II's, the pre-shaker jet XGK II.
The pre-shaker jet XGK II originally came inward a long dark bag, shown hither beside a to a greater extent than modern XGK II bag:
The pocketbook was marked amongst the one-time "Matterhorn" MSR logo.
The stove came amongst the next contents: The stove itself, a 3rd generation greyish in addition to dark pump, a windscreen, a rut reflector, an alcohol squirter bottle, a materials sack (the pocketbook inward the photograph is non the master copy XGK II type bag), instructions, in addition to a modest parts in addition to maintenance kit.
Influenza A virus subtype H5N1 closer hold back at the contents
This interesting insert came amongst this particular XGK II, an early on model XGK II apparently produced presently afterwards the cutover from the XGK to the XGK II. This insert was intended to supplement the regular instructions -- which were the instructions for the master copy XGK.
The master copy instructions state some fascinating things. Take number "6" below. It says "Use kerosene equally a fuel in addition to provide adequate ventilation..." The residual has been crossed out yesteryear mitt amongst a dark marker, but it's yet readable in addition to says, "should conditions conditions postulate the utilisation of the stove inside a tent." There yous cause got it, folks, the "elephant inward the living room." Everyone knows that inward genuinely bad conditions that yous cause got to laid upward within your tent, yet every modern stove manufacturer prints warnings inward large letters to never laid upward within a tent. Things were dissimilar dorsum then. They leveled amongst yous instead of hiding behind their lawyers.
Nowadays, MSR says "only utilisation MSR bottles amongst MSR stoves." That's a pretty funny affair to listen from MSR when yous consider that MSR stoves were designed to piece of work amongst Sigg build bottles! Indeed, the thread of every MSR see in addition to every MSR bottle is based on Sigg's threads. Again, inward the one-time days, MSR was a lot straighter amongst you. These instructions, though mitt crossed out, state "Exercise attention inward the selection in addition to utilisation of other manufacturers bottles."
Next, let's hold back at the pump. This is MSR's 3rd generation of pumps, the greyish in addition to dark pump. The rattling origin pumps were white, the minute generation, of which in that location were many variants, was yellowish in addition to black.
I won't become into all the details here, but basically the greyish in addition to dark see was a mensuration backwards for MSR. The greyish in addition to dark see is inferior inward every way except for the re-designed air render tube which is an improvement. MSR took a mensuration backwards? What happened? Well, inward 1980, Larry Penberthy sold MSR to REI. REI started making changes to cutting costs. They redesigned the XGK, eliminating several costly items similar the surge dampener, the flintstone ignition, the protective aluminum cup, in addition to the curlicue on the generator. They also completely redesigned the pump, coming upward amongst the greyish in addition to dark see pictured above, a see far less robust but much cheaper to produce. MSR in addition to thence gained a reputation for having crappy, unreliable pumps. The side yesteryear side 2 iterations (red in addition to gray, blood-red in addition to aquamarine) of MSR pumps were no improve than the greyish in addition to dark in addition to peradventure were worse. Fortunately for stove users, MSR came out amongst their electrical flow "duraseal" see some fourth dimension about 2005, a much improved pump. Is the duraseal equally skillful equally the one-time yellowish in addition to dark pumps? Perhaps, but the jury is yet out on that.
Well, let's cause got a hold back at the stove itself, shall we?
Note the stiff fuel line. The fuel line, when locked into the fuel tank (via the pump), forms share of the back upward of the stove. The XGK is genuinely a fairly stable stove despite its relatively modest base. In the photograph above, yous volition depository fiscal establishment annotation the aluminum foil neckband about the stove. This is the rut reflector in addition to is designed to reverberate rut upward to the pot, maximizing efficiency. Note also the large diameter of the generator (pre rut loop). The XGK tin lavatory take hold some pretty unsmooth fuels. Indeed, many a mountaineer has benefited greatly from the XGK's rugged, robust pattern when burning rather questionable 3rd globe kerosene piece high on a remote mountain.
Included amongst this stove are the below shown parts: a wrench/tool, a pricker for cleaning the jet, a "sintered" brass fuel filter, in addition to a spare jet.
Note the letters stamped into the jet, an "X" in addition to a "K". The "X" indicates that this is an XGK jet (as opposed to whatever of MSR's other stoves), in addition to the "K" indicates that this is the jet for kerosene. The jet that comes installed amongst the stove is typically marked "X" in addition to "G" indicating that the manufacturing flora installed jet is the XGK jet for gasoline. The "G" jet should live used amongst Coleman fuel, truthful white gasoline, automotive gasoline, naptha, panel wipe, "environmental" gasoline (e.g. Aspen 4T), aviation gasoline etc. The "K" jet should live used amongst kerosene, diesel, jet fuel, Kleen Heet, etc. Note: Coleman type fuel in addition to kerosene volition ever live the best fuels for pretty much whatever crude based liquid fueled stove. In a pinch, yous tin lavatory burn downwards some of these other fuels, but your stove volition non run equally well, volition clog to a greater extent than (hope yous know how to champaign hold your stove), in addition to may create some pretty noxious emissions. Use "alternate" fuels (fuels other than Coleman type fuel in addition to kerosene) alone when yous cause got to.
Also included was this modest squelch bottle, intended to live used for alcohol for priming.
Alcohol is the traditional agency of priming stoves that run on crude based liquid fuels. It burns to a greater extent than cleanly (especially when compared to the nasty job concern of priming amongst kerosene), is easier to command the amount dispensed, in addition to is far less prone to producing a fireball that tin lavatory shoot upward from the stove. Fireballs are especially mutual when priming amongst gasoline type fuels. Oddly, MSR no longer encourages priming amongst alcohol.
Here, the stove is laid upward in addition to ready for use. I've removed the windscreen for visibility's sake.
Here, the windscreen has been emplaced.
Time to displace her upward in addition to position the kettle on!
The XGK passes the "tea test" amongst ease.
Let's cause got a hold back at the flames, shall we? The XGK is known for it's powerfulness in addition to rightfully so.
But depository fiscal establishment annotation this shot here:
Now, I won't telephone phone that a simmering flame, well, non exactly, but that is a pretty depression flame. It took some fiddling, but I was able to larn some relatively depression flames out of an XGK. I in addition to other owners of older XGK's cause got noted that older XGK's are capable of a lower flame than newer XGK's. Why mightiness this be? The pre-shaker jet XGK II in addition to the shaker jet XGK II are thence rattling similar; shouldn't the flames live the same? I honestly don't know why the flames are different, but peradventure there's something virtually having to a greater extent than empty infinite within the jet that makes simmering to a greater extent than hard -- empty infinite that has to live in that location inward lodge for the shaker to, well, shake. That's my theory anyway. I notice the same affair on my pre-shaker jet MSR Whisperlite, that it simmers improve than whatever shaker-jet Whisperlite. This isn't isolated. I've used multiple pre-shaker jet MSR stoves. Every pre-shaker jet MSR stove that I've used has consistently simmered improve than whatever shaker jet MSR stove that I've used.
Well, in that location yous cause got it, the mountaineer's friend, the ultimate snowfall melting machine, the MSR XGK.
Thank yous for joining me on some other adventure inward stoving,

The MSR XGK
What's skillful virtually it?
Powerful
Reliable
Stable
Efficient
What's bad virtually it?
Expensive (The XGK draw inward full general -- although used ones tin lavatory live a truthful bargain)
Loud
Difficult to simmer (although pre-shaker jet models simmer better)
The swiveling wire pot supports tend to displace about besides much during use. (Newer models cause got done away amongst the one-time swiveling pot supports)
The stiff fuel line, piece adding pregnant stability, is a chip hard to pack (Pretty youngster issue)
Overall, highly recommended.
