    in your opinon, what is the youngest age for someone to use a mamod or similar steam toy?

    I think this 'helplessness' is encouraged as it enables the mega-corps to make even more money. See the present right-to-repair issues if you think I'm out to lunch. Even more interesting is finding that enough 'experts' in an a lot of areas don't know very much. Many years ago I heard this...

    Mini diesel engine.

    Your comment is quite interesting. I bought a VW diesel Rabbit (Golf in most of the rest of the world even at that time) in 1980 and averaged over 75 mpg (us) over the life of the vehicle. Drove other previously very abused gas pots in the 90s - - - with most I got a touch over 45 mpg. Drove...

    Making the site mono-dimensional has the following effect. In the thread "Wanted bill of materials for Satra O-440 " there is an admission from one of the posters that the writer and the individual that was doing the castings (IIRC) only talked machining. Now the individual has died - - - - -...

    in your opinon, what is the youngest age for someone to use a mamod or similar steam toy?

    In this vein I recommend that y'all watch a movie called "Babies" . The movie follows the first year of life of 4 babies - - - two rural and two urban. The differences in their capabilities is astounding - - - imo even disturbing. The wife found a series on Netflix (a generally useless...

    Hmmmmmm - - - if they are quite interested in the toy - - - and up to it as it were - - - - well then being totally subversive - - - introduce them to the joys of machining and fabricating. IMO more children need to be introduced to the trades (and SKILLS) - - - even a (future) politician might...

    Mini diesel engine.

    TL;DR Well it is a common problem when you are talking with multi-dimensional people. Getting frustrated with the rabbit trails will likely only hurt your enjoyment of the site. Its easy enough to glance at and then ignore any message that you don't find interesting. In fact there are more...

    New to me Mill

    Tried that. There were some goofy expectations. Most wanted a payment bond presented before bidding was possible. So I was expected to send them some from $5 to 15k BEFORE being allowed to bid. (I was thinking of bidding on things like a grouping of drill bits or other cutting tools.) Then...

    Hmmm - - - no sparking even at starts? Hmmmmmm - - - - soot causes cancer - - - - so does living. Even more so where the food you eat generally has so very often been modified from its original state. The reassurance from our national inspector - - - - " . . . for the production of good...

    Mini diesel engine.

    I do hope that you're getting a lot more than 20x atmospheric pressure in even your gas engine. In a diesel engine it is even higher. I wonder if there has been any measuring of the ozone caused by the use of electric motors in vehicles? (Seems that there has but the quantities are presently...

    Sorry - - - your information on sulfur in diesel is about 40 years out of date. Tried finding the date of introduction in North America and can't in a short search. Ultra-low sulfur diesel (0.05%) has been around since some time in the 90s. There was an increase in fuel additive...

    How were you able to find such? Here I'm really finding it difficult to find anything except from the commercial sellers and that's usually a full tariff!

    CAD /Autocad Help

    Hmmmmmmmm - - - what I'm seeing is that using models rather than drawings has resulted in an increase of pieces that just don't work. To explain - - - - when I look at 2D drawings its easy to see that the shaft MUST be +0.0000 and better -0.0005 to -0.0015 (even) and the mating part needs to...

    Crankshaft steel specification

    I have a book, unfortunately NOT handy, where comparisons between ANSI (IIRC), DIN, can't remember the Japanese code abbreviation. The book does not promise to cover every grade of everything but its only about 400 pages. Machinerys Handbook is no help either (just checked!!)

    Another Rupnow 1 by 1

    Exactly! Then Gr 10 and 12 Then look at L9 hardware - - - tough like Gr 10 but stretches more (think for use of equipment frames). The whys and whens can consume a lot of time. I do tend to do the monkey see monkey do routine (looking at what has been specd and then doing similar.

    Details of performance two-stroke engines.

    TIG welding aluminum AC is recommended. (Now if you're using a small wire mig setup - - - different answer!!!) I got it - - - Al likes a LOT of heat. So for maybe a few minutes of welding you going to increase your costs (maybe 5x as much - - - - large tig rigs are pricey!!!!!!) Why not do...

    I choose to do a quick look to see what might be involved. Well - - - for me - - - two strikes right off the bat. Needs Win 11 AND is cloud based. So to use this I would need to either buy another machine and try to figure out how to keep win 11 secure (impossible imo!!) or buy a copy of win...
