To Dust I Return

If You Can’t Breathe, You Can’t do Woodworking

I have to do dust collection. I will never be able to use my woodworking tools without it.

I was waiting for a nice Delta collector to go back on the American Express Rewards shopping list, but the danged thing is still not available. Maybe I should have jumped on it when I had the chance.

I checked out dust collectors on Craigslist yesterday. I can get a giant Dustkop industrial cyclone for a mere $250. Unfortunately, it takes up an area about the size of a kitchen table and has a 3-phase, 3-horsepower motor.

Maybe my failure to acquire the Delta machine is a blessing in disguise. In fact, I’m sure it is, because ALL of my problems are blessings in disguise. Disguises. Whatever.

I’m considering making my own dust collector. Wood Magazine sells plans. For the cost of a small Delta, I can have a cyclone which should satisfy my needs for all eternity. I just have to grit my teeth and build it. One nice thing about it: it would be strong enough to put in a corner, with long hoses or ducts. A smaller machine might have to be rolled from tool to tool, so it would be in the way.

I want to fire up the table saw and make bed covers for my mill, but I am not willing to tolerate a big dust cleanup job. Trying to suck sawdust out of the crevices on two motorcycles gets tiresome.

Today I’m trying to get the garage in order. I need to get the new rotary table and chuck working so I can put them away. When I put a dial indicator on the side of the chuck and turn the table, the radial variation is barely measurable, but when I chuck a cutter in the jaws, I get higher numbers. I was getting something like 0.017″, which horrified me. Then I moved the chuck jaws over one slot and tried again. This time, the total measured variation is about 0.0045″. If I understand runout correctly, the runout is half of that, which is acceptable. But I can’t help wondering what would happen if I took the jaws out and moved them again. And there are twelve possible ways to combine the chuck, adapter plate, and table, so this could turn out to be a long job.

I just learned that you can induce runout by tightening a chuck using only one socket. I refer to the sockets in which the chuck key fits. Can you believe that? I have to go back, tighten the chuck using all three sockets, and start over.

I guess I should look for a 4-jaw chuck. I probably should have gotten one to begin with, but I suppose optimism overwhelmed my common sense. A 4-jaw chuck can be adjusted to overcome runout, although it may have other problems if it’s cheap.

I hate to do this to my male readers, but I just learned about a pretty cool tool. You will want it, I assume. It’s called the Ridgid Jobmax. It’s a battery-powered handle which accepts things like a drill, an impact driver, an oscillating tool, and an autohammer. Popular Mechanics says it outperforms individual tools made by other companies. Get one of these with the impact driver and oscillating tool, and you would be king of the jobsite. If you also had five batteries. That’s the hitch. It would be a neat thing to have around the house, if you had limited space and a limited budget.

Ridgid makes good stuff.

I better get back to the garage and resume rearranging piles.

    Popular mechanics tested the job mac at all it’s functions, and found that it did the job as well or better than all of the individual dedicated tools it would replace (or at least the cordless versions thereof)… Which I found amazing.

    I’m seriously thinking about buying one.

    I need a planer, and a dust collector, to “mostly complete” the wood side of my workshop (I haven’t even started on the metal side). I also plan on running a central line system, and I’m going to go with a 240v single phase.

    I’m just trying to decide if I need to spend the minimum $1500 on a cyclone, or just buy one of the more powerful but MUCH cheaper (less efficient per unit volume, but WAY more volume… hmmm) double bag systems.

    Oh and I’ve got a runout problem with my drill press chuck. The motor, arbor, and shaft are sufficiently concentric that I get no vibration out to 3600 rpm. The problem is how the chuck is gripping the drill bits. It’s got enough runout that the vibration and imprecision, are a problem.

    It’s the stock generachinese chuck though. I think I’m just going to knock it out and replace it with an $80 jacobs.

    Huh, that’s odd…. I read your original post in my RSS reader, and it chopped off the bit where you were talking about the pop-mech test (actually everything after “autohammer”); which is why I commented on it.

    I have read that one can use a 4-jaw chuck on a lathe to make
    a cube (or rectangle). It’s not immediately evident what sort of regular solid prism can be made with a 3-jaw, other than flat ended hex stock, and I guess that’s not very regular.
