I'm going back to colege chemisty notes so I'll have to make a second post regarding acidic testing. I do work with nickel on a daily basis. Nickel is slightly magnetic so your material may very well contain Nickel. An easy test to perform is a density test. The accuracy of the results depends on th...

Wow! there are so many good ideas I do not know where to begin. To "flesh-in" the detail ... here goes ... The 3350-93 is not the same engine that appeared in the B-29. The -93 is mechanically fuel injected (like the Daimler DB-603) whereas the the bomber motor was carbuerated (but still f...

Unlike National Semiconductor, everything that I have ever built from a Linear Tech data-sheet has worked better than expected. Both companies hav...
