...054-1250-0 Rotary Tool for our hobby: Modeling?

If you do, did you notice if your drill bits or any other kind that you insert in the(not certain of the name) mandrel, does it wobble?

For me, let's say for example, a 1mm drill bit instead of making a 1mm hole, it will make a zero or the letter O.

Any other MasterCraft, Dremel or Jobmate bits will hit my piece multiple times and hit as fast as I press the pedal (I added a pedal) because it wobbles:



I wanted to know if a dremel does wobble or if you found a solution for your MasterCraft?

I have one, and never noticed any issues like that, but then again, when I am drilling holes that small, I do it by hand.

I've never tried with a big drill. I'll it later today. Thank's for the idea.

Thx ;-)

Is the bit centred in the chuck (the jaws)? If it's not perfectly on the rotation axis, then the tip of the bit will indeed describe a circle as you describe. It is harder to get the bit centred with smaller ones in my experience so you can check if the tool is faulty by fitting a larger bit and seeing whether the problem persists by watching it as you apply power. If that one is centred, it might be that you just need a chuck that is easier to use with small bits. I have one on a shaft of around 2mm diameter which I sometimes use as an alternative to changing collets (my drill has removable collets for different diameter bits but not all do).

Of course if you get the same issue with larger bits too, it sounds as though the drill is faulty and unless you are a machinist, I can't think of a fix other than replacement.

Unless it's a precision machine, youll have wobble. Even a Jacobs chuck in a milling machine has some. The cheaper the tool, the worse the quality control and design tolerances seem to be. Its the natuer of the beast. If i want precise, i have a micro chuck, to fit my small screwdriver. I got it thru micromark. Slow drill speed helps.

@Robert: Did all that my friend and as Matt said, it's not a precision machine.

And I'll ask (again) my last or 2nd to last question: Does a Dremel wobble? For those that once had or still have a MasterCraft?

And I'm guessing I'll have to go manual for drilling one small hole. But when you need to sand or do the multiple jobs that they are designed to do, going manual will be a bit tedious ;-)

If you're doing that much stuff to require a rotary tool, get a Dremel. Mine has zero wobble.

I now own a Dremel 3000 and guess what: no wobble

Thx to all.

Glad to hear it. Really, the Dremel is one of the best purchases I ever made.

Thx again Gary, I'm beginning to really think so too.

Question: do you own the Flexible shaft extension for the drill/tool? If so, still no wobble? Before I get one.

Yes, I have the flexi-tool but only used it once with a metal blade to cut some .5mm sheet brass over an hour period. I don't remember any wobble giving me any grief.

If, and I repeat (lol) IF you get a chance, please try it with anything that is straight, like a drill bit or something like that. Plz

Do you own the workstation, do you think it's a nice investment for 39.95$ ?

Yes, I own the workstation too. Using it as a drill press, it's less than ideal. It has plastic parts, so if you are going to drill with it, you need to start the hole by tapping on a nail. Otherwise the bit will drift.

I've used it to hold the Dremel while I worked with the flex-tool. On other occasions with an engravers bit with the RPM set at the lowest (5000) used it to thin the back side of plastic parts that I needed thinned (like the back sides of vents where I wanted the holes open insread of painted black). This way, you hold the plastic parts with two hands giving you ultimate control while the bit spins wobble-free and eats away at the unwanted styrene.

I've actually bumped the spinning engraver's bit with a knuckle and lost no flesh. I imagine at higher RPM's it might have been different. But at higher Rev's, your styrene will melt instead of being steadily chewed away.

Good Luck,

Gary

I also have the flexi-shaft. Don't use it as much as I could, but there are some things for which it really is great. I recommend it.

The work-station sucks. Total waste of money IMHO. No matter what I do I cannot get it to hold the Tool perpendicular to the work surface, so even as a drill press I find it wanting. Have been interested in the rotary tool and drill press stand Proxxon makes, as I have a precision vice from them which I like a lot. Probably have to wait till my next trip to Japan to pick one up--much cheaper that way.
