What bit to grind with

[bumber]

Nice shanks! Do you mean using the sander the whole time or just to smooth it up? But no matter what you use make sure you use the right speeds for what you are doing, because if I use those they turn to paper dust. http://www.dremel.com will have all you need to know im sure.

Shrub, I read your posts. I followed our advice. I have been using the fiber enforced cutting wheels, and then using the stones to finish up if there was a bit of a rough edge or something.

[Shrub]

Ok, i cant understand you problem then,

You saying you are getting through loads of fibre cutting wheels on one pick and also putting groves in a wheel on the same pick?

Unless your making your picks from 2" wide bandsaw blade i dont know what your doing wrong but doing somthing wrong you most certainly are,

I think its time for pictures of your picks, tools and wheels for further advice on the matter,

No I mean, I've gone through loads of slitting wheels, and now that I'm using the fiber ones, it doesn't grind down that fast. It's slow though. The stones I use for finishing touches are getting used up fast and getting grooves in them. I just kind of wanted tips on what bits to use. I will probably post some pictures a little later.

OK....So I dont remember if this was said/asked yet. DO you know how to pick locks? If not than buy a set and if you do know how, buy a set. Then when that set gets old than make a set. Hopefully by then we can help with your problem(which I cant figure out or fix at the moment). And I thought I had troubles

I disagree with bumber, if you want to make picks go ahead and try. Just be very, very careful. I use a Dremel and noting else. Instead of grinding all the material away I use the wheel to cut the pick down along the sides then grind slightly and then switch to a hand file or carbide cutter on the dremel. Also on wheels and cutters, First, I started using the new EZ change system, there simple to change and thicker and seem to hold up longer, of course they cost more, but not much. Second, I have several carbide cutters, some are just softer than others, no question, all are Dremel brand. Third, get a vise or C-clamp, a C-clamp is less than a package of dremel cut off wheels and will reduce the waste of the wheels many times over. All these are just my opinions but I have been through 5 Dremels, they even made a digital one and I had to pick that up, so I know a little bit about the subject. I suggest you read all the information here, try to apply it, and don’t give up, just be careful!

Well I was trying to say that a new pick set will be cheaper than what he has probably already put in to what he has so far. What my point(although in my head not in my post) was make sure u like what ur doing before you invest time and eventually bodily harm into something u may not like. Although i use mainly my dremel I cannot say its the ONLY thing i use, I am just saying I've spent my time and money on and know my way around my dremel!!! (still on my first one, got a single speed w/replacable brushes[electric motor stuff] it WILL last forever)

Its Cool

Wheels are consumeables so do get grooved and damaged so i guess the question is how much are you getting from them before they break up and cant be used anymore?

A dremmel isnt the tool to use in my opinon, its not designed for the work load nor are the bits quite up to it, a dremel is for hobby craft and mainly modeling of lightweight materials like plastics etc its only when everyone started useing them for everythign that theyve been bringing the bits out to do everything,

Its like drag racing a crap car, you can make it as fast as you like but it will never be the right type of car, never be fast enough and always seem inadequate but you will still race it because its believed to be the right thing to do,

I rarely state this as so many on here do use rotary tools to do picks and most make a good job of them so if it works it works,

In your case however your not happy so im suggesting to go down the proper tool route of buying a cheap bench grinder,


Just somthing ive thought of, the correct way to use a grinding wheel is to move the wheel over the work as in the full surface of the wheel must be moved over the work,

OI assume you use the same section of wheel and continuely go around the work, this is wrong, if you move the grinding heel over the work whlst moving the wheel in and out or up and down (whatever) so that when you grind you grind on every part of the wheel at some point, this stops the grooves, keeps the work cooler and is freindlyer on the tooling,

As for a bench grinder against a dremel?

I can make a hook pick in around 1-2 mins on a bench grinder from hacksaw blade to picking the lock with it, and it costs nothing,

Making one with a dremel take 4 times longer as they run faster and heat the work quicker, they also cost me money as im buying new bits all the time and also its almost impossable to get a straight edge without making it out or taking time to get it right,

Ok for the...whatever-th time, my question is "What is my best choice for a bit for grinding picks with dremel" which I have already specified... Now if anyone feels like asking again, they can look up at the thread title for the answer. I think "what bit to grind with" sums my question up pretty well.

Bumper, yes I can pick a lock, and yes I have a pick set. I do not think this is relevant though, since I didn't ask "how do I pick a lock" but rather "what bit should I use to grind the steel in hacksaw blades".


Also, on a side note, I know it's an unusual request, but could you refrain from using extensive shorthand? it's a little hard to read after lack of sleep, and, after all, we are on a BBS, not a cellular phone.

[bumber]

WELL smart guy your question has been answered in about 5 different posts. Second i was just tryig to see if you could pick so you would know if it was a waste of your time or not. I, nor did anyone else even ATTEMPT to tell you ANYHING about how to pick locks. So re-read ALL the posts and count how many times your answer has been given.

[taracor]

The question I asked WAS answered, yes, but it was an open ended question. What I mean is that maybe if someone has some kind of tip to give that can be useful, or maybe someone has been using a certain grinding bit that hasn't been mentioned with great success, I would like to hear about it. The more knowledge that is spread the better. Of course, I find most of these posts helpful, but the more input would be a good thing. I mean honestly, the bulk of the posts are telling me the same thing (use a bench grinder, or use a cut off wheel, which is what I've been doing) but maybe someone has another idea.

When making your own picks and other tools it is worthwhile to get a little background on some of the tools and techniques used in machine shops. I found the following site quite informative. I share in hopes that some of you will as well.

http://www.jjjtrain.com/vms/library.html

For example, this section in the above library may help those working with grinding wheels to better select the correct wheel for their task.

Another great resource is this site:

Just as we share our experience and knowledge around lockpicking, the above site is an excellent resource for the those who want to learn more about tool making.
