Letter Re: Advice on Storing E85 Ethanol Fuel

Jim: I’m sorry, but that Wikipedia article gave you bad information. It’s describing the situation for E10, not E85. You’ll note it doesn’t give you a reference to a study backing up this analysis. On the other hand, this Wikipedia.page does: Ethanol Fuel Mixtures The key graph is on page 32 of that reference Similar graphs and conclusions agreeing that the sensitivity to phase separation declines as the percentage of ethanol increases are available elsewhere: From the US EPA From Cim-tek Regards, – PNG JWR Replies: Thanks for correcting my error. My humble apologies for not researching my reply more …

Jim’s Quote of the Day

“…To own firearms is to affirm that freedom and liberty are not gifts from the state. It is to reserve final judgment about whether the state is encroaching on freedom and liberty, to stand ready to defend that freedom with more than mere words, and to stand outside the state’s totalitarian reach.” – Jeff Snyder, “A Nation of Cowards“

Letter Re: Question on LEDs and EMP

Hi Jim: Your blog is the best I’ve come across on the Internet. Very useful information. Regarding the subject of [Electromagnetic Pulse] EMP, are the new Light Emitting Diode (LED) flashlights more, or less immune to EMP than those using conventional incandescent bulbs? Modern solid-state circuitry is in grave danger of terminal damage in the event of an EMP occurrence. LEDs are composed of a semiconductor junction, similar to transistors and integrated circuits. Do modern LED flashlights have enough of the right characteristics to pick up sufficient EMP burst energy and become permanently useless? Your comments please, and thank you. …


Letter Re: Keeping Firearms Functioning in Extreme Cold Temperatures

Hi Jim, I’m in the middle of reading Roy E. Appleman’s book “East of Chosin“. It is an account of the tragic fate of the 31st Regimental Combat team during the Korean conflict. Several references talk about the soldiers weapons (especially M1 Carbines) locking up due to the extreme (-20 Fahrenheit or greater) cold. It mentioned how the Chinese weapons worked because they had little or no oil in them. I imagined those weapons had a short operational life without lubrication, but they worked when needed. What would you recommend to keep firearms functional in extreme cold? A dry/powdered lubricant? …


Letter Re: Expedient Footware

Jim, I was doing my nightly research on the web and discovered a great resource for making Expedient Footware. This seemed a slick and quick answer. Check out this link for the directions on fabricating sandals out of tires. I printed a copy of the instructions and they will become part of my library for that rainy day event we all hope never happens. The children and I will make our practice run set here shortly. – Matt B.

Note from JWR:

April 19th (Patriot’s Day) is a significant date. It is coincidentally the anniversary of the battles at Lexington and Concord (the opening of America’s war of secession from Britain, in 1775), the German assault on the Warsaw Ghetto (1943) , the FBI/ATF assault on the Branch Davidian church at Waco (1993), and the tragic misdirected Oklahoma City Federal Building bombing (1995).


Letter Re: Advice on Storing E85 Ethanol Fuel

Jim: Regarding your statement: :”Even E10 (10% ethanol) blended gasoline is highly hygroscopic and can absorb 50 times more water than traditional non-blended gasoline.” E10 is much more sensitive to the water/alcohol solution separating from the gasoline than E85 is. E10 undergoes separation at around 0.5% water. E85 can absorb about 20% water before separation occurs. – PNG JWR Replies: That is not entirely correct. An explanatory note from the L.U.S.T. Line Report (on Leaking Underground Storage Tanks): “Ethanol will mix with gasoline, but it does so reluctantly. Although gasoline is nonpolar, it can only hold up to 0.2 percent …


Letter Re: HK 416 Gas Piston M16/AR-15 Rifles and Upper Receiver Assemblies

James: Regarding the HK “416” [gas piston operated M16]s. I found a video about them. Do you think that [semi-auto only variants of] these rifles–or at least upper receivers–will be available to civilians any time soon? Also, do you know if they make a .308 [AR-10] version of the gas [piston] operated .223 you linked to? Thanks, – S.F. JWR Replies: As background, I should first explain that standard AR-15s, M16s, M4s and AR-10s use gas tube impingement rather than a gas piston to operate their actions. This blows powder fouling back into the action. Heckler und Koch of Germany …

Notes from JWR:

The mass media is abuzz about the massacre at Virginia Tech, where Cho Seung-Hui, a foreign student used a pair of handguns (9mm and .22 rimfire) to kill 32 unarmed people. The mainstream media pundits are pointing fingers at the college administration that failed to raise an alarm after Cho killed his first two victims, and fled. Two hours later, he killed 30 more students, and then himself. But the issue that the media is failing to ask is: Why were all of his victims unarmed? The answer: Because it was against school policy to have guns on campus, and …
