By stage, do you mean tool rest? I've seen a lot of grinders without tool rests, it boggles my mind how people can use them that way. But if you were going to, wouldn't you want to build on out of metal?

Yeah, this is what I was thinking. Awesome. I'm building a platform for it that I will attach everything to, so I will at least attach it using snaps or wingnuts so I can move it around to each position easily.

Also, I don't remember if it was you or someone else but someone was saying they live in NC - have you ever met Roy Underhill?

Sounds like the guy spent 30 years full time (roughly 60,000 hours) making quality pianos the old fashioned way - of course he's going to have mad skills; skills few of us will ever achieve in a hobby. We can get isnpiration from some of his ideas and do some of the things on a smaller scale. Personally I'd never commit myself to making such a tool chest like that because while everything fits in there beautifully what if you wanted to change something around? Of course I'd love to own it and just play with it - it's like a man's doll house.

Well, yeah, but the Stanley #1 is basically the absolute pinnacle of collectible iron-body planes, followed closely by the less-tiny #2. It was so short a run that it was essentially "not" produced, so today it's 100% collectible for collector's sake. Funny thing is, it's also basically a stupid design -- if you want a small-body standard-angle plane, you'd just get a good block plane. A man-sized hand doesn't even fit into the handle! It's funny to me, because you see some truly amazing plow (or "plough") planes, or stunning infill planes at around the same price and you realize how silly that really is. I've seen a fully original british infill with a high-angle blade that smooths better than a new Lie-Neilsen, and was infinitely more beautiful (I think the wood was ebony or something crazy).

You can get one for under $20. I built mine from some MDF and it works really well, and the price was right because I didn't have to buy anything. I pair it with my tiny little Shop-Vac Hangup. You don't need a huge collection volume at the vac because the bucket collects most of the bulk, and the Hangup sucks like you wouldn't believe so it works amazingly well, without taking up a ton of room. Also, consider this a hugely positive review of the Hangup, it's great for cleaning up the bench, under the saw, and around the lathe.

When it first opened up, Schwarz and one of his Pop Woodworking staff photographers were down there shooting a project that Underhill had done for the magazine. I wrote an e-mail to the school's main info e-mail, asking if it was cool if I stopped by and got some books signed by each of them. Underhill himself wrote me back and invited me to come over, so I ended up meeting the both of them that way. Basic impressions: Roy is super nice and genuine, he has an incredible passion and energy for woodworking. He also tried to flirt with my wife. Chris is a really smart guy and I'm really glad someone like him is involved in woodworking. He's part historic scholar, part practical craftsman, and part teacher/communicator. He will dig up old woodworking tomes, scour them for what is basically forgotten techniques, learn and apply those techniques, and then disseminate that information amongst the woodworking populace. truncated aardvar posted:Of course I'd love to own it and just play with it - it's like a man's doll house.

I really like the idea of the SawStop but I've never really understood why the blade needs to be brought to an abrupt stop? Why wouldn't it be just as effective to have the motor cut out, and the saw retract into the table and spin to a stop at a normal rate? Thereby saving $60 of break-pad plus a new saw blade.

Because how are they going to sell you a 70$ brake cartridge every time you almost cut your finger off. Not to mention the saw manufacturers having it in their best interest for their blade to be destroyed in the process. It's just business. Annoying, but it's a fact of life, I guess.

anaemic posted:I really like the idea of the SawStop but I've never really understood why the blade needs to be brought to an abrupt stop? As I understand it, the mechanism that brings the blade into the table is simply the rotational energy of the blade being transferred into the swinging stop. It's easier to just use a shitload of kinetic energy to slam the blade downwards than to use some crazy mechanism to slam the blade downward without all that convenient energy spinning right there. Plus, whatever could bring the full height of the blade below the depth of the table that quickly just using electricity would be very, very significant and likely more expensive.

It looks like the air comes in the side of the thing, spins around and then exits the top after throwing all the dust against the walls of the cone-thingy, which then drops the dust down into whatever you're collecting it with. The next section in that article suggests it may be possible to build one out of a busted dyson and a paint bucket...wheels spinning... And anyone still in the market for a clearance Ridgid router- depending on the HD store you might be able to have them transfer one from another store to your local if there are any in the area. I just picked up one that way

Right, I was more curious from a practical standpoint. "Air comes in from the side" doesn't really tell much about an actual setup. "Where do you plug the shop vac in" really meant precisely that. See, my shop vac also has an out port, and I could plug that into the side, thus forcing air to swirl around inside the cyclone and exit the top, but of course then my shop vac's reservoir would still be filling up rather than the separator's hopper. Pretty sure I've got it sorted in my head, was just looking for confirmation.

http://www.youtube.com/watch?v=nQQZkGFKTtU Shows the dust coming in from the side, the shop vac is attached to the top-center of the cone, sucking in mostly clean air while the majority of the dust falls to the bottom and into the barrel it's attached to. It looks like that one has some sort of fin molded into the clear portion to kind of direct the airflow into a better spiral. Here's one where some guy just glue-gunned what looks to be a large pop bottle to an ice-cream pail and hooked up his house vacuum, almost every bit as effective as the one above. The all black hose in this one is what attaches to the dust collection port, the silver/black hose is your shop-vac. http://www.youtube.com/watch?v=wA8f0okOwlM edit: the related videos are all kinds of fun and education too, between those and the Woodwright's shop episodes I guess I have my evening playlist picked out.

It takes a full 1/8th of a second to stop once it senses that proximity, though.  It's about nine full turns of the blade, though. Granted, that 1/8th of a second theoretically starts ticking before your hand is even under the guard, so you'd have to cover the remaining inch or so and make contact with the blade in less than that time, but that's only, what, 0.5mph? Actually just a little less than.I'd like to see an analysis of time vs. blade rpm from the time that thing senses proximity to the time the blade is completely stationary. I have a pretty good notion of what it should be, in a general sense, but I'm curious about the specifics. And of course the same thing for the sawstop braking system.

That's well over 500 complete turns of the blade 500 * 8 = 4,000 per second 4000 * 60 = 240,000 per minute I don't have saw that rotates at 240,000 RPM.

Oh right, I did that as if it was 1/8 of a minute, not 1/8 of a second. Durrr  So, 9 full turns of the blade? 4500 / 60 = 75rps, 75rps * .125 seconds = 9.375 rotations I'd still like to see a comparison of rpm vs. time for this and sawstop, though.

I think SawStop might win that one because it's using the rotational energy in the blade to pull it down into the table. The problem is it costs you money every time it does. And let's be honest, 1/8 of a second is going to be enough time unless you're trying to get to that blade in a hurry. It's probably still possible to get injured, but the risk is reduced significantly. And I'll take that over $70 cartridges and $200 new saw blades every time.

From that video it seems like the system depends on the operator touching the metal part of the guard to activate the brake. Which is fine for the guard in that position, but when you crank it higher for thicker wood there's more chance that you'll run your hands towards the blade without coming anywhere near the metal parts of the guard. It also does nothing of course if the guard is removed. It's better than nothing and for a lot of situations I'm sure it would work well, but I'm wondering if you'd get lulled into a false sense of security instead of staying alert.

Here's my contraption:  Click here for the full 768x1024 image. The vac is sucking through the middle hose, which sticks down into the bucket a few inches. The hose from the dust creator is entering at the perimeter, at a jaunty angle to encourage the cyclone to form. It is held in place with plumber's epoxy because that's what was on my bench at the time. My first attempt had the vac line too high inside and it ended up pulling some dust straight over, although heavier stuff still whirled around and fell to the bottom. When I added some more length it really helped cut down on the bypass dust. The plate is two pieces of MDF, one circle fits inside the bucket and the other glued up to rest on the top. There's enough force to keep the whole works together during operation so I didn't even bother with a retention system, or a seal. So it's two round pieces of crap with two holes. The collection efficiency probably isn't nearly as high as a fancier one with a cone and such, but what do you want for zero dollars and 20 minutes? I pretty much built it in a fit of rage after getting the shop covered in MDF dust from my router table.

Sweet, thanks, thanks pretty much exactly what I was looking for. Unrelated: anyone know of a good way to get the backing off of copper flashing without actually peeling it off (and thereby wrinkling the copper)? So far, I've tried acetone (no effect), alcohol (no effect), and mineral spirits (works, but slowly, and will itself need to be cleaned off, maybe via the aforementioned alcohol?)
