I've got some old tools that were my father's that I'm trying to clean up. One is an old miter saw with a detachable blade that's kinda similar to the one shown in the attachment. The blade is pretty rusty and I was thinking of giving it a bit of blast in an electrolysis tank. Does anyone know...

On the weekend I was trying to figure out an easy way of estimating (rough approx at least) how much axial force (point pressure) was required for drilling a given material at a given drill diameter. The upshot of this was that I decided to try and make a small calculator program to give not...

I was at one of my local hardware stores yesterday and noticed that they has some hole saw sets marked down. They had two types, bi-metal and carbide. I've already got a bi metal set so I was gonna pick up the carbide ones, but when I looked at them they didn't have carbide teeth (or tips) like...

The other day I was thinking about the sound levels on my new impact driver, and wondering if I should use ear plugs/muffs with it: http://www.garagejournal.com/forum/showthread.php?t=239009. Today I remembered that I've got really old analog sound pressure meter that someone gave me years...

I just bought my first cordless impact driver last week. I figured I'd use it mostly on screws, decking screws and lag screws etc, so I got an impact driver rather than an impact socket. I've only had a couple of opportunities to use it so far, but not surprisingly it's a pretty noisy little...

Ok, here's a multiple choice quiz. What's the best material to make a good burr from. a) Carbide b) Marzipan c) Cheese :confused: No this isn't a troll post. I just thought you might get a bit of a laugh from the email I received re a carbide burr I ordered from ebay a few weeks ago. :D...

Over the Christmas period I got a bit carried away on ebay and ordered some cheap **** from HK - China. One of the things I bought were these cheap hex shank bits pictured. This stuff was just for occasional home use, mostly pilot holes in wood, so I figured they'd be ok. But serious these...

The other thread on cobalt drills just had me looking through my drill bits to see which, if any, of mine are Cobalt. I've only got a handful which I believe to be M35, but to be honest I'm not 100% sure and they're only marked as HSS. The uncoated color of these drill is very slightly bronze...

Currently I have neither, but I'm thinking about getting one or the other (not both). I'm wondering which option would work the best if I wanted to try and get both functions (to some extent) from the one tool. 1. An impact driver with a hex to square (male) adaptor, so it could be used...

The battery charger for my (off brand) Li-Ion drill has two LEDs, one red and the other green. Each can be in any of three states, off, blinking or solid on. On the back of the charger is a label which describes how these LEDs illuminate for each of six different states of the battery/charger...

I'm looking to get a drill press and was thinking about one with the third (slow speed) spindle. Anyway right now I've got the chance to get one fairly cheap, but it doesn't have that intermediate spindle for very low speeds. It does however have a 5 pulley / 5 speed setup, with 600 rpm as the...

After reading how many people here liked their step drills, (http://www.garagejournal.com/forum/showthread.php?t=227945), I thought I'd have to give them a try. I looked on ebay and cheap Chinese 3 piece sets go for as little as $7 to $8. Decided to stop by and take a look at what the h/w store...

Ok, I was bored last weekend so I made this just for fun :lol:. Can anyone guess what it is?

Just wondering if many people use hex shank drill bits like the ones pictured in the attachment. I've got a tiny set here, only 1.5, 2.0, 2.5, 3.0, 4.0 mm (obviously not the set pictured). TBH I'd never used them much in the past, but I've recently noticed that they do seem fairly useful for...

I recently bought a new Li-Ion drill/driver. It's only a fairly small one, 10.8 volts (12V max) so the battery pack is quite small. I like it ok except for that one thing, it doesn't stand upright like my older (and heavier) NiCd battery tools did. I didn't think this would bother me, but it...

Post your oldest cordless drills. :) I was cleaning out the shed a few weeks ago and found these two. They're old Ryobi 7.2 volt drills from somewhere about the late '80s (I think but tbh I'm not 100% sure of when). The bright "kermitt" green one was my very first drill, it was pretty much a...

Some hand tools like files and rasps we cannot sharpen. So when they start to get dull it's time to replace them. I use a half round rasp fairly often for shaping wood, but I never realized how dull it was until I recently bought a new one. The new one removes probably about 50% to 100% more...

Has anyone noticed that some manufacturers claim their nominal voltage on Li-Ion cordless products at 3.6 volts per cell, while others using the exact same technology claim 4.0 volts? I've noticed this in a few different product lines. The individual Li-Ion cells have a nominal working voltage...

This might be a dumb question because I've never seen it asked before, and I'm guessing the answer is probably that it makes no difference. But I'll ask anyway. You know how you should back off the tension in your "clicker" torque wrench when storing to help maintain calibration. Does it make...
