Lubricant for shredder blades
I will preface this by saying this is probably a stupid question: I recently bought a near-industrial grade paper shredder finally after several cheaper ones have broken on me due to cheap-*** construction even on what should have been reasonably good machines. Anyway I am serious about... -

Question for engineers/PEs etc in re: torque multiplying "ratchet" looking tools
Question for engineers/PEs etc in re: torque multiplying "ratchet" looking tools McMaster and some other supplier offer (for no small $$ by the way) a thing that looks like a big/long 1/2" driveish ratchet with a slightly larger head on it and apparently a gear mechanism inside that multiplies... -

Bolt torque resources (especially nylock)
I have been looking with very little luck for a comprehensive bolt torque standards table that includes nylock nuts and bolts. What little I could find had some vague notes about adding 5 in-lbs for nylocks but I would think that this is not perfect advice given that the prevailing torque for... -

Best way to store/organize huge quantity of 1/4" hex bits?
I have acquired (it's almost a compulsion with me when I'm in hardware stores) a truly stunning quantity of 1/4" drive hex bits. I have everything from P2 bits (probably >>a lifetime supply) to the full range of S-Torx to some weird offset philips-looking security bits to tri-wing. I have... -

OT: Best gun lubricants/solvents/etc for semiauto?
I was wondering if people had any strong opinions about the best lubricants (brands) and solvents for cleaning and maintaining semiautomatic handguns. Hoppe's seems to be common, but not universally loved at all, and Break-free seems to be popular but derided by some serious gun people, so...- proFeign

Brazing aluminum?
Howdy, I need to attach aluminum rod to a piece of rounded aluminum sheet. I'm thinking (no TIG available) that if I drill an interference-fit size hole and press the rod into it and then braze it that will give me a relatively strong attachment point, but I don't know if there is an... -

Holdridge 3" radii cutter won't cut 3" hemisphere!?!
Howdy, I just got a Holdridge 3" radii cutter for a project at work http://www1.mscdirect.com/CGI/NNSRIT?PMPXNO=1801567&PMT4NO=42343140 and I need to cut a nearly 3" diameter hemisphere on the end of a 3" Delrin rod and glue another hemispherical cap on the end. But the throat of this cutter... -

Glass a liquid at room temperature?
Not to stick my head in the proverbial lion's mouth :eek: of PM flame wars but I have noticed in several (at least five) other current threads the topic of whether or not glass is a liquid or not at room temperature has come up and has lots of credible arguments for it NOT being a liquid at room... -

how much do you trust your best measuring tool?
I'm talking here about micrometers and calipers and indicators and height gages... If you have a quantum tunneling unobtanium-enriched laser supermicrometer that is accurate to angstroms that is interesting too but I'm specifically wondering about small tools and what people with way more... -

why would you ever buy a metric only digital mic/caliper/etc?
I get that some people never need english units but you pay the same to get metric only and get less functionality. Are there any reasons you would? QC? Cal management? ISO regs? Do tell... -

How to adjust micrometer thimble tension - Mitutoyo Digimatic
Howdy, I just got my second in what will hopefully become a full set of mitutoyo coolant proof digital micrometers... I have the 0-1 and now the 1-2, and both came with a spanner wrench that fits the cap on the end of the thimble (mine are both "ratchet-friction" which I really dig) and the... -

Mitutoyo "Quickmike" - Worth the money?
Has anyone actually used one of these? http://www.mitutoyo.com/TerminalMerchandisingGroup.aspx?group=1088 I really want one because it's such a neat mechanism, but the 0-1 is $500 new (found one used for $260, but holding off for now). In case you haven't heard of it it's just like their... -

cheap "roll press"??
Howdy, Is there a low-cost device with a ~24" width that can press two pieces of adhesive fabric together? The cheapest thing I've found is a sheet metal roll from enco or MSC but not having one in front of me I don't know how adjustable they are with respect to adjusting load between rollers... -

Cutting a hemispherical end profile onto a steel dowel?
Without a radius cutter how would you cut a spherical profile onto a hardened steel precision dowel? We're talking about a 1/2" dia x 2" L steel dowel probably <58 HRC. It doesn't need to be a perfect hemisphere and I got OK results by using a carbide insert tool (TPMM cheapo) to cut steps... -

How do you take apart a dial caliper?
Are there instructions on the web somewhere? I have a Mitutoyo 6" I'd like to repair but it doesn't seem to have any way to take the body apart without pulling the face off, and the needle with it, which might be how you do it... Any instructions on the web? This is a caliper I bought as... -

Which height gauge to buy?
Howdy, I am trying to round out my set of measuring tools and I'd like to get a really nice (preferably used since new nice ones are $$$$) height gauge. I don't care if it's vernier/digital/digit/dial but I would spend the money on one with super-high-end fit and finish if I could find a good... -

OT - Lapping gage blocks
Howdy, I recently won an eBay auction for a set of Grade 2 (+/- .000004") gage blocks that were described as "new" but the pictures made me expect what I got: a very lightly used set. There are a few very light (looks like fogginess on the datum faces) on a few of the blocks. An "arkansas... -

Howdy, As the "machinist" at my company I was able to get a budget to buy a new lathe and milling machine. This week I am preparing a safety/operation lecture for our Bridgeport clone where I will be showing people how to operate the machine safely, but mostly this is a refresher for people...
