wrote: I'd prefer a fire piston. https://en.wikipedia.org/wiki/Fire_piston Good idea. I've built a few of those over the years for various nefarious purposes. The problem for me was that the oxygen inside the cylinder is rapidly depleted once the tinder starts burning. The hard part is removing the piston and tinder from the cylinder before the fire goes out. It can be done, but you have to be quick. ISTM it would be a trivial modification of a frame pump or mini pump. With a compression ratio of 25:1, the internal pressure would need to be atmospheric pressure times the compression ratio minus one atmosphere for gauge pressure or: (24 * 14.7 psi) = 353 psi The volume of a floor pump is sufficient to obtain a 25:1 volumetric reduction if the piston goes all the way to the bottom of the tube. However, it looks like length of the piston has been intentionally shortened to prevent achieving such a high compression ratio. The gauge on my floor pump also says that's not going happen (at least until after the gauge explodes). I tried removing the hose and pumping furiously to see if anything leaked. It seems that the rubber piston seal and one-way valve leak rather badly. Without major redesign and possibly some mechanical leverage, it's not going to happen. However, there are multistage bicycle pumps, designed to hand inflate high pressure bicycle tires, which might work: "High pressure, multiple-stage air pump with valve body inlet port arrangement" https://patents.google.com/patent/US8047818B2/en If unsuitable for making a fire starter, it might be useful for building a bicycle defense air gun giving new meaning to "taking the lane". Hmm. But then there would be no need for the butane. Yes, marketing can be complicated! Actually it's quite simple. The purpose of marketing is to convince the potential buying public that they have a problem that is worth solving. The purpose of sales is to then convince the buying public that they have a solution for the newly created problem. Of course, this creates yet another opportunity for marketing to identify a problem with the solution and the cycle repeats itself ad infinitum. Soon, everyone will be riding bicycles armed with a bicycle pump that can double as a flame thrower, air gun, or in an emergency, tire inflator. -- Jeff Liebermann PO Box 272 http://www.LearnByDestroying.com Ben Lomond CA 95005-0272 Skype: JeffLiebermann AE6KS 831-336-2558 |

I forgot to mention another use for a conventional bicycle pump. I received a free and very used Coleman 413G camp stove: https://www.google.com/search?q=coleman+413g&tbm=isch Unfortunately, the previous clueless owner had left E10 gasoline in the tank under pressure. The ethanol plus water in the gasoline leaked into the air pump cylinder section of the tank which corroded the bottom the cylinder. The damage was too extensive to repair. So, I plugged the piston pump section of the tank and replaced the filler cap with one that had a Schrader bicycle valve inserted: https://www.ebay.com/itm/291854107043 Using any bicycle pump, I can now pressurize the tank, and sacrifice my dinner on the camp stove to the bicycle gods. -- Jeff Liebermann PO Box 272 http://www.LearnByDestroying.com Ben Lomond CA 95005-0272 Skype: JeffLiebermann AE6KS 831-336-2558 |

You'd think that the inconvenience and the expense would put most people off of tubeless, but you never know. Just like I question the inconvenience, weight, and expense of CO2 cartridges versus a mini-pump. You can buy a mini-pump that weighs as little as 25 grams, much less than a Co2 cartridge and an inflator, but some people love the speed of a CO2 cartridge (until they run out of CO2 and have to borrow someone's pump). The MTB has wheels and tires that could be set up, but I’ve never really been tempted, I tend to use higher pressures (slightly) 30psi or so as I hate the sidewall wallowing, it punctures so rarely that is a non issue. The Gravel has non tubeless rims and again on the whole it works, i mix road and gravel and mild MTB trails, again settled on a psi that is just above the point the tires wallow if I push them. Which for Gravel is 50psi. I hate CO2 total pain in the ass, I have settled on a mini pump with hose, which copes with tires from 35mm to 60mm+ if perhaps slowly! Roger Merriman |

Ha far from it! Though DH racers tend to run higher pressures as they load up the tires and do jumps and what not, it’s also where tubes hung on the longest in pro ranks as far as I’m aware, push hard and you can roll a tire off the rim. It’s XC racers who tend to run seriously low pressures that and some Gravel riders, though most are more conservative ie higher pressures, in real life! Roger Merriman |
