Der Rote Kampfflieger

That's brave going back in there and sanding it down like that. But it is good to see this one back on the bench.

:v

Brave ain't the word I'd use. It was pretty bad, I had to address this if I ever wanted to show this thing.

As you can see the dremel got away from me, maybe it's time to invest in a new hand piece rototool.

Anyone have suggestions?

All depends on how much you want to invest.
 
Our jewelers at work each have 3 flex shafts which they use all the time. Flex shafts can be good, but if the bit binds up even a little, the shaft will yank on you as it tries to twist.

I have an OLD 80's vari speed Dremel. I use it with an external Dremel speed control and have the speed control on the Dremel turned all the way up. This combo give me a real nice smooth speed control and can slow the speed from a bare crawl up to Full-Tilt-Boogie! It also wont jump around as the bit grabs as the motor is right there.

I have also use the foot speed control that the Foredom flex shafts use and working with plastic you really need a much finer and more stable speed. Once you set the speed control it won't wander if you dance your foot around. High speed melts plastic.

Here is my OLD Dremel set up. I still like it much better than the newer current stuff. The speed control works better than anything else I have ever used. The drill press is solid and the Dremel is mounted solid and doesn't wiggle at all. I can do stuff with this setup that can't be done on the newer stuff available.

Hunt on ebay for one of the old speed controls. They usually are not too outrageous on price, but more than well worth it. You can use your newer Dremel with it just push the speed switch on it all the way up and regulate with the speed control.

Edit

Outrageous?! They run in price from $10 up to about $50 including an old black style Dremel that fits the old drill press. (and there were a couple of those too)

I am thinking about getting some back up tools. :hmmm

One last thing, my setup gives enough control for me to use it to drill #70 ish holes with carbide bits. (and not break the bits)
 
Thanks Paul, the problem I have with Dremel is the motor wobble. I don't think the Dremels of today are near what the ones we use to have.

Really looking at these Foredom setups. Lots of options and a well supported community.
 
I am using a Ney dental lab motor (would you expect anything else). I have had it since 1994, it goes from 0 to 30k rpm with sufficient torque to not stall at slow speed. I think I paid 300.00 for it back in the day.
 
With extra small drill bits stalling usually snaps them right off. In that case speed control is more important with a stable motor.

I have not used a dental lab motor, but any flex shaft will torque the shaft if it tries to stall. That is what I didn't like about the flex shafts.

I would love to see a photo of your dental lab motor John just know what you are talking about.

No flexi-shaft here.

HA, found US Dental Depot, searched and they have Foredom tools. :rotf.

Not so much worried about flex shaft getting bound up on plastic.
