The penalty you pay when AKBD's are not regularly checked

#1 Post by Harley »

AKDBs ( Anti-Kick-Back Devices ) on table saws MUST be checked regularly, cleared of dust and lubricated....otherwise you pay a penalty like below....

....and this was the result of not checking it for two days of solid work.

The piece that hit my arm was only 3" wide and 12" long

Take heed! :mrgreen:

:shock: Y-ouch!!

Did you do the four-point check after it happened? Eyes, limbs, fingers, cussing....

Glad to see you made out as well as you did. :wink:

A pity that you had to be reminded so harshly, Harley. Heal well, my friend!

And take heed, all the other forum members! I am in a situation where I, through no fault of my own, am no longer able to work, build speakers, or DJ anymore. It also interferes with my bass playing. Everyone is one preventable incident away from a life-altering event. And incidents like this are very preventable when you think of safety above everything else.

Man, that looks painful! Sorry about the accident. I have also felt the wrath of a kicked back piece of wood, and it's not fun. I was fortunate that I had a shirt on, and it hit me in the stomach so all I got was a deep bruise. Wishing you a speedy recovery! And to everyone else: BE SAFE!

Ouch.

All you guys doing lots of this need these:
http://www.microjig.com/
There is no cut under 7 or 8 inches wide in my shop done without it. It makes possible cuts that cannot be done safely without it. It takes an extra 30 seconds to a minute to set it, depending on the cut. Better it gets cut than my fingers. I became a dealer a while back, and have never bought any to sell. After seeing this, I'm going to put them in stock after the first of the year.

Check your fences also. I bought one of these on sale a couple of weeks ago. http://www.in-lineindustries.com/alineit.basic.html

If your fence tails towards the blade you're in kickback danger. Upon measuring my fence was off about .020, my blade runout was tailing .005 the other way. Those are teeny amounts, but after I adjusted for them, the difference was apparent. The finish of the cut became much smoother. According the manual, either set the fence perfectly parallel, or tail the fence away from the blade 2 or 3 thousandths for the safest cut. Minimizes the possibility of kickback.

Ever since I ripped open a fingernail, saw safety is priority #1. Kick back is the the most common injury, and the hardest to anticipate, even for experienced users.

Every tool demands respect. I have a nice phillips screwdriver shaped scar at the base of my left index finger to prove it. :oops:
If it's too loud, you're even older than me! Like me.

+1000. Kickback can't happen when you're cutting with a panel jig on large pieces or a hold down on small ones.

No, I was cutting again about 5 mins after the pic was taken.

Plus, that was on Saturday - it's now Tues

Very wise advice. My gate tails out by about 1mm over the whole length too BUT that cut I was doing was at 45degrees on 1/4" ply so that's about 3 times the surface area of a normal 90 degree cut - lots of friction. :cry:

I think if you work with a table saw long enough, you're going to get a kickback experience or two. My first time I got hit in the crotch with a big piece of oak. Luckily it was above my bits and pieces!

I keep getting a 403 on that microjig, Leland. What product is it that you're describing? The splitter doesn't look like it'll help issues as you describe, such as the fence misalignment.

+1 to Bill's panel jig. I use a different sled than Bill's design, and I've accidentally gotten that kicked back at me slightly. Heavy side of the board lifted the panel just enough to graze the blade... Bill's design ensures that kind of stuff shouldn't happen.

Ah, it's working now. Good ole IT folks.

Edit: wow, not bad for $60! There's push sticks that are $20 that don't do nearly as much as this thing does. I'm going to call up woodcraft and see if they have a demo.

I'm about to order another set of DR280 hardware ( Drivers will go through the appropriate buying channels of course ) so I should get one from you I guess.

About how much would it cost me ex store Parsons?

I'll give them a call today. I got set up as a dealer about 6 months ago, but never bought any.

FWIW with a little imagination you can make some virtually impossible cuts, safely. I ripped the 1/8 overlap from some crown molding that was only about an 1/2 thick after the cut.

Sorry about the accident pal..... this is a painfull reminder for those (we myself incluided) who are sometimes too intrepid with our bench tools
I use a self made handle and the less posible blade height but sometimes this is not enough


about the scar you can hide it with a scarface tatoo it will be a huge hit (pum) :bash:
There is a very thin line between fail and success. It is very thin so, why are you scared???
