Default The MOST Awesome Volume Knob Has a Price...

I was in one of my employee's offices when I saw trhe sample package of stop covers for the Sloan Flush valve (think public restroom. The perfect polished Nickel plated Brass 2" diameter cover weighing almost at least as much as $400 worth of mid grade bail weed. Lucky for me my employee wanted to make me happy. I got one for free. I have some delrin at home. This would be a nice 1 or 2 hour project and net me some free relaxation and a cool knob for my next amp.

Long story short. The drill press bound as it cut through the hole in the side for the set screw and the cap got pulled up to the top of the bit. It was only a split second, but I could feel the bit cutting as it cut through my finger. It bled a lot, and I'm not ashamed to admit that it hurt a like a.... well, a 3/16" drill bit through the finger. A quick trip to the hospital for a bit of sewing and I managed to finish the knob tonight. I guess this next amp will have a story to go with it...

EDIT: Don't try this at home. the anesthesia they use requires 4 shots directly into the tip of your finger. The doctor didn't sugar cote it. He said "It's gonna hurt like hell". It did.

The drill press is the shop ninja. It will try to disembowl you at any time.

Always use a drill press vise. Always rotate the vise or workpiece of its big enough to touch the column. This prevents whipping you if the drill grabs. Listen to the sounds the cutter makes as its clearing the work, and feed it slower.

Learn how to resharpen your bits so they won't grab as they come through the work. You have to grind back the edge to lesser angle. I can post a pic of this if needed.(I run a machine shop)

This is the piece of equipment I see the most injuries on. Take your time, don't use power tools if you just yelled at someone, or them at you.

At least you didn't do what a friend of mine did - using a hand drill to put a hole in a knob!

Picture someone drilling a knob, holding the knob in one hand, the drill in the other. Well, you can imagine what happened... the drill bit slipped, and went right through the palm of his hand. Ouch! Lesson learned: always secure the work piece, don't use your hands!

Ouch ouch ouch!

I stepped on a rusy nail this morning, and have been limping around -- but it ain't nothing like that finger of yours. Ouch again!

Sure hope you like the knob, it is a beauty.

Please do, (though a new thread may be appropriate). All my woodwork tools are kept razor sharp, but I've never had much luck with drill bits. Any hints would be greatly appreciated.

As for avoiding injury, a hint. When using a nail gun to fit small pieces of trim, make sure you took all the larger nails out of the air nailer you were using previously, so you don't fire a oversize nail through your trim, through the stock, and into your finger holding the work in place.

With the cost of having your finger sewed up I guess you could call this volume knob a true audiophiles component. At least 400.00 for this one piece.
I hope you did not cause any permanet damage to your finger. That has happened to me several times with a hand drill and it does smart a little.
All in all how did the project turn out. Tad

Wink off-topic medical advice

Tell your doctor next time it can be done with 2 injections that are less painful (at the base of the finger; the Oberst technique). Then sue him. Then buy an identical knob for input selection.

Kurio-us-guy,

welcome on behalf of all members of the sliced finger club, next time try slicing the bone as well.
Very smooth nobby though.

With any amount of luck there won't be a next time. No need to sue him. He took me in ahead of everybody (he was finishing his shift). I would have had a very long wait otherwise. Here's a first. I beat my paperwork through the emergency room. they were finished with me and I hadn't signed any fee paperwork.
