Years ago I pulled the tranny on my 914. The cone bolt for the shift linkage was rounded off by the DAPO, so I left the shift rod attached. Unbolted the motor mounts from the body, and pulled the tranny. When it came free of the clutch, it rolled over and smashed my hand between the concrete and the sharp edge of the motor mount. Cut to the bone at the nuckle of the middle finger of my left hand. Went to get it stitched up.. At the hospital they numbed it and had me wash up. The guy in the next bed was there with the flu, and he started retching when I looked at the cut and said "Hey, this looks like chicken fat!"


Spent 4 hours with 3 fingers cut to the bone while in the army. Never, ever get your hand in the way of the parachute shroud lines during chute deployment. The risers are like razors. Sliced tendons in my fingers badly. Still have dexterity problems with my left hand. Ruined me as a guitar player.

Has anyone seen the new table saw with the "instant brake" that if something containing more than 50% water touches the blade the saw stops. Works great on a hotdog I saw on NPR. No more than 1/8th' deep cut!
Yep, I hate radial arm saws too!

Geoff

I heard the story. I got queasy when they ran the demo with the turkey dog. Man that blade stops fast. I have a full wood shop and always wear protective glasses and keep my head up. Joiners are what scare me. Sixteen years ago a chain saw kicked back on me and made a nasty mess of my cheek. I was extremely lucky. Three levels of stiches but the cut did not go through to my mouth.

A joiner is another tool I won't have in my shop. I use my big ass planer instead.

Here's a link to the video of the new table saw. I've already ordered the 5 horse model.

That is friggin amazing.

How does it sense the water content of the material (ie, your finger).

Guess you might not be able to cut voluminzed (whatever it is) wood. Of course, anyone who cuts that kind of wood on a table saw needs their head examined.

Later,
Tom

The blade has to go into your skin before it senses via electrical resistance that it is not cutting wood. Reaction time is in the thousands of seconds. When it senses skin a preloaded brake trips and stops the blade. The guy who invented it has a doctorate in physics, is a patent attorney, and a woodworker.

It is tougher to square a piece of wood without using a joiner. Planers like one surface to be flat. Joining an edge also is best done on a joiner. I just have a lot of respect for those blades spinning face up and never, ever run my hands directly over the blades. I also never join short lengths.

This isn't tool related but ...
Back in the 70's, each December several of my good friends and I would go skiing at Tahoe after finals at Cal Poly. Our trips were fun but uneventful for several years when, one year, the bad luck caught up to us.

A passing skiier knocked our my brother's front teeth with the shaft of a ski pole.

A friend, a ski patrol member and very competent skiier, fell and broke a leg.

My roommate had his ski binding release while moving slowly downhill. Leather safety straps were the standard at the time so the ski remained connected to his ankle. The front tip of the ski dug into the snow and, since it was still attached to his leg, the butt end of the ski lifted up as he moved forward. The end of the ski caught him in the crotch and, like a pole vaulter, he slowly fell forward with his full weight on the butt of the ski which, of course, was firmly jammed into his memory makers.

It took 50 stitches to close his scrotum. For many months afterwards "50 stitches" became the standing joke while still inspiring awe and horror.

There was considerable doubt that he'd ever have kids but he and his wife have two sons who are now in college.

scruz, I have a jig for my planer to accurately edge plane a board, so no need for the joiner there. I also own about 50 saw blades. A blade for every purpose. One of them is for leaving a smooth glueable edge, so no need for a joiner there. I can s4s boards in the planer much more accurately than with a joiner. A misalighned joiner will make your board convex or concave. Bad for glue joints.

Tony,

When's the last time you had a tetanus shot? My doc says adults should get one every ten years--unless you work on a 914, then it's every five . . . .

Back to the drill press . . . as defined by Peter Egan (in an old Road and Track): "A tall upright machine useful for suddenly snatching flat metal bar stock out of your hands so that it smacks you in the chest and flings your beer across the room, splattering it against the Rolling Stones poster over the bench grinder."

Take care of that hand,

Steve A-

A few months ago. #1 smart ass in class decides to remove the weld from two pieces of Alunimum round stock. Around 8'in, on a lathe. So he clamps the thing in a three-jaw chuck and kicks it on around 800rpm. Just as I hear someone tell him to take it easy, the part comes flying out of the chuck about 8ft high and rolls past me 15ft away. If I was any closer I'd be sporting a cool scar.

vsg, Jig for planing edges? Sounds good. Who is the manufacturer? I hear what you are saying about joiner blades being out of alignment and/or convex. Everything has to be absolutely perfect to get a clean square cut. What kind of table saw fence are you using? I need to upgrade mine.

scruz, I make all my own jigs and fixtures. It's part of the job and something I excell at. I'm 3rd generation. I use both a Beisemeyer and Delta unifence and several shop built fences for various specialty applications. I can cut a perfect circle on my table saw!!!!!


The jointer knives can only get out of alignment from left to right (horizontally). The convex/concave errors are caused by the infeed and outfeed tables not being parallel. Most homeowner type jointers don't have the precision adjustments necessary for perfect alignment.

Tony,

Bet the stitches made you forget all about the chicken pox! I got them at 40 and was quite miserable. Hope you heal up quickly.

Good tool story
A co-worker of mine was doing some trim work in his house. He has a 10" mitre saw to cut his baseboards with. While sitting on the floor in a tight spot, he reached over to the saw, dragged it to him, put it on his lap and cut his last piece of baseboard.
He never really thought about where the spinning blade went after it passed throught the wood and the bed of the saw.
He still walks with a limp.

No problem with th thread hijack. After reading all these stories I have decided that what happened to me is nothing!!

I have a lot of respect for you guys that do cabinets. Several years ago I really got into building spaeker cabinets and even ended up doing some very fancy unusual designs. Getting straight edges, having things be truly parallel is a skill that I envy. One day when I have my own garage I'll get back into it, but its jsut not practical in an apartment.

I did have a tetanus shot recently. 3 or 4 years ago I stabed myself in the hand with a small metal file and couldn't remember when I'd had my last one, so I got one.

That auto-shutoff tabl saw sounds really cool!!!! Its amazing they can get the blade to stop so fast. The spring for the brake must be under immense tension.

Wow, nicely made Kevin. If there's one thing i really miss about being in college, its having access to a well equipped machine shop for free.

I guess I'm slowly building up a home shop, but its amazing how many tools (=$$) you really need to do things correctly, and ahem, without removing flesh.

I love finishing a part that is all shiny and dimensionally accurate. There's something very satisfying about that.
