Clearing chips off a band saw blade...
Awl--
A'ight, I've sorta recovered from burnin up the goddamm powerfeed on m'Bridgeport, 'n' ahm sure gonna be more careful powering up my bad-assed Kalamazoo 9x16 hydraulic saw, which is actually the more important machine right now. Speaking of which.... The 1" saw blade *really* cuts, bruhs, w/ boucou chip volume. Kalamazoo actually provides--and strongly recommends--a blade chip cleaner, which is basically a rotating wire wheel just after the cut/before the drive wheel, causing the chips to fall down in a mesh basket, rather than all over the quite substantial coolant tank/pump, or packing into the drive wheel bay/screwing up the blade. This is an "ok" method, altho the brush wheel tends to wear, fall off, get lost, bent, etc. Note that the Kal has *two* low-pressure coolant jets, integrated into each set of blade guide arms/bearings, w/ shutoffs--really neat. One jet hits the blade just prior to the cut, and the other jet sprays the blade "after the cutting fact"! Was always puzzled by this second spray--it cain't be to dislodge chips, cuz it's not really aimed right, and it's pretty weak--mini-giant, donchaknow. Purpose?? So a cupla idears come to mind, which you all might find useful (or even already have) in your own applications.: A separate more powerful mini-giant, dedicated solely to chip dislodging (ie, focused at one point); A different type pump altogether, low volume/high pressure--don't know much about these. Would an old hydraulic pump mebbe work?? I got two! The spray really need only be a cupla sq. mm, for effective chip dislodging. Tapping into my fadal pump, and blast the **** out of those chips, bruhs... But tank logistics become pretty messy here, not to mention literal high-volume coolant mess... OR....drum roll Compressed air???? mebbe w/ a little mini-giant coolant, and blow the wet chips straight down! A little noisey, mebbe, but likely really effective. Comments? Idears? Would also like to make a pan for my $199 horzl bandsaw special, and put a mini-giant on it as well. Inyone done this? TIA. ---------------------------- Mr. P.V.'d formerly Droll Troll |

Clearing chips off a band saw blade...
You know, the worst part about it is, I know better...
As soon as the **** happens, I clap my forehead, and groan, Had I only thought for a goddamm minute... But, in the heat'o'battle, something usually gets lost.... usually something flammable... and expensive... But I look at it this way: Making my life eternally miserable is how God gets some of his kicks--that, and the occasional genocidal campaigns the world endures. Ergo, he won't let me die--at least not too soon. Ergo, I won't get bone cancer--which is sumpn I really worry about--dudn't run in my family, but I worry about it anyway. After dat Fadal charred my garage ceiling, I thought, ****, now ahma live goddamm *forever*, w/ a goddamm fadal that I'll never ever ever be able to fix... but, free of bone cancer. Funny, true story-- I have a very very old built-in hidden safe, a Schwab, w/ an inner "jewelry safe", a sep. 4" thick round door, w/ its own combination... wow! Well, when I bought the house, it was of course locked, w/ no combination. My heart sank... After supplying all kinds of documentation to Schwab, one of their good ol' boys gave me the factory combination, on the chance it was never changed. Well it was, but the lock is kind of peculiar anyway, so while muddling w/ this combo for quite some time w/ the guy over the phone, in a literal 1 in a million shot, I *accidentally opened the safe*!!!! Unfuknbelievable.... The Schwab guy certainly didn't believe me, figgering I was just some goddamm moron who, finally, correctly dialed in the factory combo he gave me, and just didn't realize it. Not so, as I was able to grok the true combo after removing the inner dial from the open door--really no big deal. Well, my stratospheric joy was shortlived, as I quickly became *certain* that I would be diagnosed w/ bone cancer within the month. I was in fact terrified for the next 3 mos... Now, I don't go thru those bouts so much anymore, as I have sunken more into a low-level ongoing Existential/karmic Ennui, which occasionally spikes into Existential/karmic Crisis. Far better, tho, than intense worrying about bone cancer. Which, I have ascertained, is really pretty rare. Still..... Much more, I'm sure, than you wanted to know. ---------------------------- Mr. P.V.'d formerly Droll Troll "Tom Accuosti" wrote in message t...

Anyway, that's what I got, it sure works slick, and you want the needle valve, so you can match the air blast to the job. It is bolted to the saw blade guide. An employee made this for me one day, he liked it so much at his former job. Pete |

Clearing chips off a band saw blade...
Pete,
This sounds really neat, novel, mebbe perfect! And more than a just a good idea, as you have a working version! Can you give more particulars, like how the block is held on the blade, the path of the air, etc.? Source for needle valves? If I infer correctly, your air comes straight from the top of the U. I wonder if holes lower down, just above the kerf, wouldn't be better--more effective, w/ less air. Ahm thinkin mini-manifold here, that could deliver both coolant *and* air, at different points/angles to the blade.... Also, if the sides of the U project down below the teeth, the air force might be amplified a little *and* the chips better directed downward. Also, it might be that the best, if not the most convenient, place for this unit would be before the second set of guide bearings, so's the blade would go thru these bearings chip-free--might add some life to all parts concerned. Howz the air noise?? Have you noticed any improvement in saw performance, reliability, blade longevity, etc. as a result of this item? If worse comes to worse, I'll do sumpn w/ a wire wheel (mebbe two, like the guide bearings, but sprung on the blade), but I'm definitely up for your idea, skill-set permitting.... ---------------------------- Mr. P.V.'d formerly Droll Troll wrote in message oups.com...

Clearing chips off a band saw blade...
The block is bolted to the blade guide. It -Barely- has enough
clearance for the saw, there is a small gap, you hardly use any air at all. You hardly notice any noise. Since it is part of the saw blade guide, it stays aligned even when you adjust the saw guide... Basically it looks like an extra blade guide in front of the blade guide. (Some blade guides are carbide blocks) And this protects the blade guide, And since it is only .5" thick, it doesnt take up much space, so you can adjust your blade guide in close to the work. The closer it fits to the blade, the less air ir takes. It won't wear out, and it only uses air when tyou are cutting, and very little at that. I found a needle valve in a box of stuff I got from an auction. Try looking in there. Or maybe McMaster, or MSC, or somebody else's catalog, or some shop in your area. Tom is the expert at brushes, Clif is the expert at diverting threads off course. Pete |

Clearing chips off a band saw blade...
Here's a new one for you: Weld and brush at the same time...hook one lead

They're very helpful people in selling small quantities and they're generous with product information. If you're in the UK, deal through Bentley Chemicals. Pouring is easy, but it's worth rigging up to vacuum degass the poured moulds. A simple vacuum handpump is adequate - I do small stuff in one of those Vac-U-Vin coffee jars. |

GD Gary-You're best bet would be to buy solid rod and machine it. I used to have parts cast with urethane. To get the properties I wanted the chemicals and curing process was pretty involved. I could buy urethane that was castable by myself but it just wasn't strong enough. You can check with TAP Plastics. They do have the stuff. See if it has the hardness and toughness you want. Then try a plastic company for rems of urethane and try machining it. If you needed bushings then surface finish wouldn't be that important. It used to be that Laird Plastics had rems. I don't use them anymore and so can't say. But Laird does have retail outlets in several cities. ERS |
