Re: Make a sled that handles both square and miter cuts

Years ago I concluded that the best table saw sled was one of these -

Safer, tougher, more accurate, longer lasting, etc etc.

Re: 2014 Cartouche Award Winner Announced

For a moment there I thought the patterns on the top of his tables were derived from particle accelerator results; and despite realising that they aren't I still find myself wanting to see such tables...

For example, this shot of a detector - http://0.tqn.com/d/chemistry/1/0/f/i/LHC.jpg

Re: SketchUp 3D Basecamp -- A Brief Roundup

Educational establishments should, as a general rule, *never* teach using a single example of a tool/technique/application. That's not 'education' it's 'training' - and training is something appropriate either on-the-job (yes, employers should damn well pay to train people for their particular jobs!) or at a trade college, or similar late-stage environment.
If students have only been exposed to AutoCAD, or Word, or Angry Hippos v1.13b, or any other single-approach tuition then they are going to be less flexible and less capable later in life. It's the old problem of "if you only have a hammer, every problem is a nail", writ large. It can ruin cultures and economies.

So, yes, schools should use SketchUp - along with whatever other CAD and related design tools they can rustle up. From pencils to CATIA. Any vendor with enough brains to be in business should be making sure there are no-cost options for any school or college interested.

Re: Why do you work wood?

...because I make and fix things. It's just what I do without needing any more reason than 'because I do'. I build in wood, metal, words, bytes, pictures. If I don't have anything to build I'll debug something. Can't help it.

Re: Brian Boggs Branches Out

Beautiful 'sun chair'.
A word of warning about chair back profiles though; many years ago Russell Malloy established through a set of tests (done for a chair project at Parker Knoll) on a sizeable group of testees that there are a couple of noticeably different back shapes needed. There are those of us needing the curved-in lumbar support shown on Brian's chair and there are others needing a much flatter profile. Russell's solution for a production environment was an add-on lumbar support but I can't see that working for this chair. Two subtly different models would probably be fine for a small production design though.

Sadly I can't find any online references to the tests, though as the project was done in the late 70's it was well before anyone would have thought about that. In fact I can't find Russell at all, though since he was well into middle-age when tutoring me at the RCA in '82 I suppose he might have died by now.

Re: UPDATE: Deadline extended again for tablesaw safety comments to the CPSC

Yay FREEDOM! I must be free to invade your house and shoot you without the dang gubmint getting in my way. Wait, that wasn't what you meant? Oh well, be careful what you demand. You might not like the side-effects.

Rather than specifying the technology to be used, any laws involved should specify the intended result and the degree of error acceptable. A SawStop unit will not prevent all table saw injuries - some other safety device might well stop some that it misses. What to do if they are mutually exclusive? A law requiring the tools to have some mechanism that reduces the risk of amputation would be a reasonable thing; the practical problem lies in making regulations that clearly specify what an acceptable reduction is and how to measure it and what happens if the device fails to live up to expectations.

A minor practical consideration on the legal side - I suggest that the patent/licensing laws be modified such that any device that is required by law(s) cannot be subject to any patent restrictions i.e. if someone designs a device and lobbies successfully to have it made compulsory in any manner, the patent coverage is removed and no license is required to use it.

Re: Appeals court upholds Osorio tablesaw verdict: Feds consider landmark safety standard

If a woman can sue for spilling hot coffee on herself and win, what are the chances that any argument is going dissuade this stupidity.

You need to be careful before arguing law based on 'facts' derived from poor news sources. If you actually look up the court records you will find that -

McDonalds had had in excess of 700 complaints of prior injuries caused by the temperature of their coffee; 190 degrees or sufficient to cause serious (3rd degree!) burns in under three seconds.

The old (81) lady spent over a week in hospital, requiring skin grafts and offered to settle for about the cost of the medical work.

McDonalds refused and so it went to court where they (McD) behaved like spoilt children and eventually got zinged for the actual damages requested plus, obviously, costs and then tripled as punitive damages for being persistent idiots.

As with many such cases the final court settlement was much lower ($480,000) and the actual settlement was likely even lower and covered by secrecy agreements.

So, no multi-million award, a stupid corporation, a badly handled issue and utterly mendacious reporting by the press.

Now tell me, do people object to da gubmint telling those poor oppressed electricians to use insulated wires in houses, just to stop stupid people from touching them and getting a teeny-weeny little fatal shock?

Re: The Easiest Finish Ever

This sounds like an excellent excuse for an article on finishing (and maybe other products like glues?) for people with assorted chemical sensitivities. Obviously for a lot of people that simply don't like the smell of oil-based finishes the answer could be water-bourne products; that's what I do. But some people are *really* sensitive to certain chemicals. There are probably medical conditions that permanently or temporarily require you to avoid some things.

Re: Blade brake inventor aims to compete with SawStop

RWoodCutter said:- " You don't need to stop the motor or the inertia of the motor, just disengage the pullys/belts"

Interestingly enough I've been working on an idea rather like this for a while. You can, with suitable design, do even better. The less inertia you have to fight the less time it will take to stop the blade and the less damage it would cause. Hell, just the noise of a SawStop cartridge firing at a demo was enough to give half the older guys watching near-heart attacks! A different sort of collateral damage…

I should write up what I have worked out and publish on the net somewhere, at least that way no one would be able to patent it for prior art reasons.

Re: Backyard Rock Makes a Fine Furniture Accent

Sort of related but honestly more of an FHB than FWW idea - I just made towel rails and paper holders for my house out of ½" black iron plumbing pipe and fittings. Polished up the pipe with a belt sender to get rid of the scale, de-greased and abraded the cast fittings, assemble with some loctite and spray paint. An end cap serves to stop the paper roll sliding off. Perhaps $40 for three of each.

Re: AWFS Tool News: Rockler Rolls Out New Crop of Innovations

Strictly speaking you didn't 'innovate' since that requires not just having an idea and making a working example but actually producing a sellable product and getting a business going.

Inventing something can be as simple as realising "if I add this to that I get a better back massage" or as complex as "after thirty years of billion dollar research we can finally make kitty-litter that doesnt smell:. Until there is a business making money selling it, it ain't innovation.

So taking a simple idea that might have been used forever and making a successful product out of it is innovation even if it isn't terribly inventive :-)

Re: Kitchens In SketchUp

Well I designed all my kitchen cabinets a few months ago and have pretty much finished building them and installing them. I didn't bother to go overboard with the textures but the detail level was enough to generate a Layout set wi dimensions, construction notes and cutlists. I put the SU doc in the warehouse at
http://sketchup.google.com/3dwarehouse/details?mid=36b8a3f3b84f026c1a65fb062aae4e37 should anyone be interested. I'll try to find somewhere to put the PDF of the Layout file...

Re: Hand Drawn in SketchUp

The problem I've noticed with tablet/pens is that although they seem like a nice way to *draw* they are lousy ways to *navigate* in SU. A mouse with a scrollwheel makes it really easy to zoom out rotate, zoom back in and get to a new viewpoint in double-quick time. For me, that ends up being more of the time than might be saved by having a nice pen to draw with. Having to frequently swap would become terribly annoying.
Perhaps a pen with a scrollwheel would work? You could possibly find other useful things to do with a wheel on a pen.

Re: New 12-inch Miter Saw from Bosch

As a small aside and a pointer to a fascintating bit of reading, the linkage Bosch is using appears to be a "Sarrus's Linkage" invented in 1853. See www.howround.com look for "How to draw a straight line" and go to the bottom of the page. Lots of neat stuff there.

Re: CNC is Knocking on Your Shop Door. Will You Answer?

Do the 'purists' scratch iron ore and limestone out of the ground with a stick, smelt it themselves, form the steel, forge the tool, fell the trees, cut the lumber and then finally make some furniture?

Nobody is going to stop anyone from using any tool of any level of technical sophistication. If you like to make tools from iron ore, go for it. If you like to carve with a chisel made by hand or by CNC machine, go for it. If you like to use the latest Festool and Felder, go for it. CNC is merely a different form of tool and can be used for beautiful things or mundane things.

There is no 'spiritual' nonsense to worry about. It's just an old fashioned form of the deranged woo that passes for 'new age thinking' in too many places.

Re: Would You Like a Front, Side, and Top View?

This is where the Pro version is worth paying for; it's so easy to use Layout to produce full sets of drawings with views, details, annotations, whatever. Print to pdf to share or take to the printshop for large sheet paper copies. I've done a couple of pieces on LumberJocks; no idea if non-members can get to them but let's see-

Re: UPDATED: Giveaway and Poll: The Most Requested Woodworking Gifts of 2009

A router Boss setup might be nice. And a pony. Pink.

Re: Poll: What accessories, jigs, and shop gear are on your holiday wish list?

Would that be a lifetime-including all DVD-issues-and-website subscription for FWW? I'll take one.

I'm exceedingly lucky; I have almost all the machinery I could plausibly want and a fair bit of time to play with them. Long may it continue!

Re: Poll: What power tools are on your holiday wish list?

My most important power tool accessory would be Dr.Cameron (from House) standing by ready to kiss my ouchies when I hurt myself with one.

Re: Poll: What hand tools are on your holiday wish list?

I want a set of L-N chisels just because.

Re: Are CNC machines ready for Fine Woodworking?

I would tend to agree that a CNC machine (indeed any machine) is the modern equivalent of a stable of apprentices that get to spend their time being bored silly with all the tedious bits.

Or, if you want another way of thinking about it, treat them as a router with an infinite number of built in jigs. I'd love one.

Re: Difficult Dimension Placement

A trick I've used a few times is to place a guide line or two in the relevant places and the dimension will stick to the intersections created. Once you have the dimensions marked you can delete the guides.

Obviously this has a deficiency in that altering the dimensions of your piece will not affect these 'orphan' dimensions but you can't have everything.
