    I liked it. While the comments about component substitutions are good to see, this instructable is simple, straight-forward, and easy to follow. Good job.

    Excellent job! Good, thorough instructable. You should not be put off by the "If you're not doing it the way I think it should be done, you're wrong" comments. I have learned over the years that for every one of those people, there are several that appreciate the time and effort spent to illustrate how to do something instead of being an "expert" that instead of SHARING information and knowledge, hides theirs and nit-picks those that do.

    How to make a Mini Forge

    The "new" MAPP gas, which ISN'T MAPP gas but costs as much as the OLD, GOOD, MAPP gas cost, does indeed not burn noticeably hotter than propane. Extra cost is NOT justified in my opinion, and is purely marketing (deceit) riding the coat-tails of the "good stuff" which is apparently no longer available.When you get as old as I am, you get tired of seeing GOOD, WORKING, products discontinued or replaced by INFERIOR products. Especially when the INFERIOR replacement ("upgrade" or "new and improved"), are sold at a premium price.To the point of this Instructable: Use propane. MAPP gas, while a superior product, is sadly extinct.

    How to make a Mini Forge

    I just checked 'around' the web using Google, and find that the "old" MAPP gas is indeed no longer made. What a shame! Same story I have seen most of the 65 years I've been alive: Replace an excellent product THAT WORKS with an inferior "upgrade". Same holds true for so many software "upgrades" too. Since I see no historical evidence or record of this type of 'entropy', does the propensity of this starting in the 20th century signal the decline of civilization? That question is only slightly tongue-in-cheek.

    The last time I BOUGHT a canister of MAPP gas (as opposed to actually USING it) was a couple of years ago, so if the change occurred within the last couple of years, I can't help you. Sorry.. I hadn't heard about the mixture change. I'll have to look into that.

    Great instructable. Just what I was looking for to forge railroad spikes.I won't argue with the experts that equate MAPP gas and propane combustion temps, but my personal experience with both suggests that MAPP gas IN USE burns WAY hotter than propane. While it costs significantly more here in AK, I have completely abandoned using propane canisters unless I am concerned about overheating something. The time-to-melt (solder for sweating joints) or time to cherry red (annealing brass) is close to half that with propane when using the same tip. I have to be careful not to melt the brass with a MAPP gas canister, when I have to WORK at melting brass with a propane canister.

    3D Printer Part Recycling Grinder

    Nice instructable. Provides excellent conceptual design for further development in size and capabilities.While the following question may appear off-topic, it isn't so far off that I think it is out of place.Can "milk carton" plastic be used for filament material in a 3-D printer?I have long wanted to use plastic milk cartons for 'something else' AND simply "chew them up" so they don't occupy so much space. If that plastic could be used for 3-D printer filament, I would get serious about making something like this device to chew up milk cartons.

    It is an interesting process, and has merit, I suppose, for it's novelty. However, at 65 years of age, I am increasingly mystified by how in this 'digital age' many of the "new techniques" that are supposed to be "easier" are in fact substantially more complicated. It baffles me that someone could imagine that this process is either 'simpler', or 'clearer', or 'easier'. It is none of those.While I am sympathetic to the assertion that different people learn in different ways, EVERYONE - let me repeat that for emphasis - EVERYONE "memorizes" just fine. If you didn't memorize "very well", you couldn't write, (you have to remember how to FORM sentences and words); You couldn't SPEAK, (you have to MEMORIZE words and their meanings), etc. Memorizing the...see more »It is an interesting process, and has merit, I suppose, for it's novelty.

If you didn't memorize "very well", you couldn't write, (you have to remember how to FORM sentences and words); You couldn't SPEAK, (you have to MEMORIZE words and their meanings), etc. Memorizing the "multiplication tables" from 1 through 12 is simply "work". If you "can't do it", AND you can walk, talk, and write, then you are just too lazy to do the work associated with that memorization.

    I think you make my point: "I am increasingly mystified by how in this 'digital age' many of the "new techniques" that are supposed to be "easier" are in fact substantially more complicated. It baffles me that someone could imagine that this process is either 'simpler', or 'clearer', or 'easier'." You call something that takes too many steps for me to bother counting "simpler" than remembering that 6x7=42.BUT... let's not make 'something' out of this that it isn't. I think we all agree that this is a novel technique. For those that "need" it, especially those long out of school, good for you, and "good for" the author of this 'ible'.

    Kids today DO NOT have half the time we had to "learn things". I taught at University and my wife is a high school math and science teacher. I 'know the system'. I acknowledged the reality that some people learn "differently", some learn some subjects "faster", some have "special needs". I also said this was interesting in its novelty. BUT... it is NOT "simpler". It is NOT "easier". It is NOT "clearer". It IS more complex. There is MORE to "remember" than what one has to remember when one MEMORIZES the table. It has one SERIOUS drawback other than complexity: It COMPLETELY fails to clarify or illuminate or explain the FUNDAMENTAL CONCEPTS behind multiplication. The author of the 'ible' made that caveat to s...see more »Kids today DO NOT have half the time we had to "learn things". I taught at University and my wife is a high school math and science teacher.

The author of the 'ible' made that caveat to start with (in so many words) and therefore I did not press on that issue, but you are "defending" this technique as "reasonable". It is NOT. It IS interesting. It IS a "different" method to "get to an end". I wasn't being "mean". (Nice try. I'm surprised you didn't call me 'racists'.) "Tricks" and "short-cuts" are kinda 'cool'. But those come AFTER the foundation has been laid and there is UNDERSTANDING of the principles. NOT as a substitute so a 'test can be passed.'The author of the 'ible' didn't assert that this was a substitute for basic understanding, YOU did. I am NOT taking the author to task, I am disagreeing with your (tink01) assertion that "this is a neat way to learn". It is EXACTLY NOT a way to "learn" anything except a difficult way to get the answer to a multiplication problem.
