It's better to turn than
burn...

Several things can cause burning.

No chip removal. This happens with downshear bits on a CNC router if you make a hole that's really close to the size of the bit. There's no place for the chips to go...

Or if you don't have any flutes at all it could cause this. I had this happen with a boring machine bit the other day.

Turning too fast might cause this also... Router bits that turn fast and but move too slow will do this.

And of course a dull bit could do it as well.

Lot's of rubbing but little cutting action is what causes burning... I bet you can't rub two sticks together fast enough....

Reply #32 - Dec 23^rd, 2005 at 1:33pm The big culprits are usually, drilling too fast, not clearing the chips and dull bits. If it starts burning right off, then it is probably a dull bit, but could be too much pressure at too high a speed as well.

It may also be related to the type of wood. Cocobolo, Bocote, Mun Ebony and many of the other woods that are oily will smoke even though its not really burning the wood. But if you get a good sharp brad point bit and use it only for drilling pen blanks, make sure you don't drill through into something that might ding it up, and keep it clean, it should drill a lot of blanks before it ever gets dull enough to burn.

As far a the burn, like others I would look at speed and remove the saw dust as much as possible. It tends to pile up at the bottom of the drilll bit sometimes and blows it out. I have the problem with some of the walknut burl I use, and find a squirt of windex in the hole in the last inch or so helps in reducing blowout.

One item of note in storing pens in plastic bags or tubes. At one point I had this problem and read about why. it happened. Some of the gold plating was flaking off on my pens. Evidently, after I completed a pen using CA glue as a tube glue and finish and then sealing it in a tube caused the plating to flake off. The recommendation was to either use a different kind of glue like poly, or let the pen air out for a few days, until the fumes disapated.

Hope I explained it well enough.

Ned, you do have a good idea there. I usually have an order from my wife about a week before Christmas and have to do the batch thing. I think that if a guy were getting ready for a show and needed a couple of hundred pens or so, he might use the batch method for that as well.

On the other hand, with a little pre-planning (like I know what that means Grin

), your method would have you a good way along the same process. You are starting out the same way as I do with my batch (or production) method. I just go all the way to completion, one step at a time. Cut, drill, glue, turn and finish, assemble. Cuts my completion time per pen in half.

The big advantage is that spur of the moment gift that you can give. Someone comes by the house. You want to send them off with a nice gift the remember the event. Twenty minutes of turning and finishing and another 5 to assemble. There you go. In less than 30 minutes they have a one of a kind piece that is truely functional. If they don't mind a bit of dust, they can even watch it being produced before their very eyes. A great show for most folks.

Turn 'em round & MERRY CHRISTMAS.
