  • As some of you know, I have wanted to stop managing H-M for some time. It's a tremendous strain on my personal life. I want to set up my own shop. In September, September 15, to be exact, it will be 8 years that Hobby-Machinist has been in existence.

    I have been training VTCNC to run things here. Dabbler is going to learn too. I feel that they are ready to start taking over the operation. I will be here to help in case they need, but I don't think they will. Tony Wells is and will be here also to consult with. I will be doing backups, upgrades, and installing addons. Other than that, I will not be around. I am leaving this place in good operating condition, and financial condition.

Hi,
I have started doing some machining. I'm getting a large amount of chips (big and small). Was looking at putting an electromagnet in a pvc pipe with a button to turn the magnet on when held down. Was looking at an 80kg strength magnet (about $30 off ebay). I can reduce the strength if needed by reducing the voltage. Has anyone done this successfully with an electromagnet? Any suggested pitfalls to this plan?
Cheers,
xxxx_guy

I like my baton magnet, but the stronger it is, it will be drawn to other metallic objects also. Vices, table legs, etc. I do use it on the floors for the dogs to limit splinters.

Wot...don't ye blokes ave brooms dan unda?:grin:

Seriously, it may seem like a good idea, but with repeated applications things tend to get magnetized that you really don't want too.

And I do a lot of aluminum, can't see using it half the time. I am with ya Derf, broom and vac works just fine. :encourage:

Plus the added advantage of cleaning up all the other dirt occasionally.

For steel chips/swarf I use the HF extended magnetic thing above. For aluminum, I use a small house broom that has the bristle tips split/fuzzed. It picks up the bigger swarf like Velcro by just poking at it. I then use a shop vac for the smaller stuff.

I keep the shop vac close at hand and I tend to use a chip guard when I can to keep them from flying off to parts unknown.

Sounds like if you build it you'll use it . I'd say try it and then let us know how you make out . We may need your model over ours.

One neat trick (that I think I read here) is to use a strong magnet in a plastic baggy.
Once full, turn the bag inside-out and either throw-away or dump into the recycle bin.

I made a mat out of alternating 1x2's and spacers held together with 1/4x20 threaded rod. It's easy on the feet and most chips fall thru. Just pick it up periodically and sweep the chips left behind.
