Topic tags/keywords: question

I have a 14” Grizzly drill press. Recently it started to wobble a bit and the prob turned out to be the arbor. So I called up Grizzly and ordered a keyless chuck with integrated arbor as that just made sense to me and I really wanted to try the keyless chuck. Since then, one of two things has happened. A, I have lost that “manly” ability to figure out how things work, B, it doesn’t work very good. The problem is that I can figure out out to tighten it ALITTLE, but not even enough to send a 1/4” bit through pine. The only way I can get it tight is to grab the pulley and oppose the force I put on the chuck. They say you can use a spanner wrench with this, but how do you hold it? Its rediculous. Its not like on a cordless where you can spin it to tighten and give a tug against the motor. All that accomplishes is turns the motor. What am I doing wrong? Help please!

There should be a collar above the part of the chuck that turns . Hold the collar with one hand and tighten the chuck with the other.

That would make sense right? But its just one sleeve all the way to the jaws. The only other thing to hold is the bit itself, which isn’t always smart, and is impossible if say you have a mortise attachment on.

Got a picture? I’m trying to visualize a keyless chuck you can’t grab with two hands. Except by turning it on and that sounds like a quick recipe for sanding off all the hard won calluses!

I will try to get one posted tonight when I get home. And yes, that would be a disastrous recipe.

Here are some pics of the chuck. Yes it is just a generic grizzly. It just has one sleeve on the outside. I am struggling to believe that somebody thought this was a good idea, so clearly I don’t understand it…right?

John,

I don’t see the pictures – there are just error messages from photobucket. I’m not sure how you tried to post the photos. You should be able to click on the “img” button and then either upload from your local drive or give the address of a photo on the web.

I have never seen a keyless chuck with only one grip area. In the end you just need a chuck spanner like the one pictured here, if you note in the Grizzly catalog regrading this chuck it points out a spanner is not included.

I see the photos now.

It looks like an odd chuck (I can say that because of all the years that I have heard it). If there is a spanner required to tighten the chuck sufficiently, it seems like it trades a key for another tool.

That is good thinking, but the spanner only tightens what your hand can tighten on the knurled sleeve. Leaving me still where I am, spanner or no. I am glad to hear that it is not a “normal” keyless and will likely take up this discussion with Grizzly. A guy should be able to tighten his chuck

I keyless chuck normally self tightens so you don’t have to really crank it down to hold the bit. Normally you have a spanner with a keyless chuck since in high torques usage they can self tighten to the point that you can’t open it with just your hands and the opt section usually has a small hand contact area so the spanner works on the top portion where you can’t get as good of a grip.

So I contacted Grizzly tech support. They said “yep, you are right, it only has one sleeve and cannot be tightened without holding the motor pulley” (a tough feat when you are tying to turn the sleeve and hold the bit as well. I asked if it was really engineered that way “yes” they said. What could be done about it? I asked as a useless chuck is well, useless. “Nothing”. I am currently waiting for a call from somebody with a little more authority to trade this out. Who would’ve thought that it was designed to not be tightened. They actually agreed that that was the case and told me I shouldn’t have chose that one. ITS ENTIRE PURPOSE FOR EXISTING IS TO TIGHTEN (yes I understand that it doesn’t need to be that tight, but try to tighten yours, keyless or not with only the motor resistance. Ain’t happenen.) Sorry, just a little pissed at grizzly right now. Thanks for the help fellas

It actually seems that most of the Asian imported keyless chucks with integral tapers are built the same way, they are designed to be used with a spanner, but it is usually included, they should have told you that not the non-sense about holding the pulley (but a DP with a quill lock would work too). If you could get your money back I would say to get a keyless chuck and the correct taper from Shars, they have better quality imported chucks and generally cheaper. You don’t need an integrated taper, the difference between TIR on an integrated taper and good taper/chuck is a non-issue in wood drilling.

So here’s the final outcome of the keyless chuck problem. I was able to return the other one to Grizzly. The Shars recommendation was a great one. I was (as you said) able to get a nice keyless, arbor and even had them throw in a keyed chuck just in case and it was all cheaper than the one from Grizzly. I installed that one and it works like a dream. Two opposing sleeve (an a couple spanner wrench holes) that works real slick like you would expect a keyless to do. I put an 18” bit extender in to see how straight it spun and there was about 1/4” at the bottom where as before, it was over an inch. Problem solved. Thanks LJs!
