    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    Thinking about what marka12161 said, I am going to try this: The W-T wheel is 1.2" wide, but if I use a 1.0" wide tire without anything done to the wheel grooves, I will end up with a mildly crowned tire since the narrower tire will not rest on the wheel edges which are high. There is a crude...

    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    Excellent point on grooves keeping the tires on. But I'm hypothesizing one step further: If I put the crowned urethane on the top, it will be larger diameter than the bottom with a good rubber tire (which is worn in the center and needs crowned which is achievable.) I believe only 1 wheel...

    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    I was maintenance helper at small factory and the horizontals had a slow rotating wire wheel the brushed the chips off the blade - but no cooling. I'm still not clear, for coolant hydroplaning (like car tire on wet road), the grooves would be in the tire??? If in the steel wheel wouldn't do...

    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    The reason I said wood speeds is that air will start lifting the belts (flat and V) off the sheave at high speeds and various methods are used to let that air escape (dimples and holes are common.) This problem is in supercharger v-belt drives at high rpm, 7000 rpm on a 6" sheave, I'm not doing...

    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    As far as the grooves, I'm going to sand and fill with JB Quick Epoxy. The wheel edges are high a perfect for "screeding" level across the rim. That would be the "better" job. Tempted to angle grind a crown into the wheel where the grinder would propel the wheel. Then slip on a urethane...

    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    That's fast cutting for wood - metal is dead slow (about 10x slower)

    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    CROWNING: Is it harder to crown urethane belts? My bottom rubber is cupped a little but still in good shape - still thick enough to get some crown on it. CROWN BOTH?: do I really need to crown both wheels? I know the Crown Demonstration Videos show one pulley crowned. It sure would be...

    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    I remember in the 70's, DoAll had a store in Irwin, PA on Rte 30. I got large carbide burrs sharpened for a couple/few dollars apiece - couldn't believe how inexpensive. I'll bet they might have had tires. Also there were industrial supply houses.

    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    Well, before the internet, where in the world would you get band saw tires? I can't even imagine. I'll bet the damage to this WT was done many years ago.

    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    You bring up a good point: if the wheel diameters are not the same, then the blade will not be vertical thru the guides. But it does bring up the issue that both wheels should be the same diameter. The bottom rubber is OK, but is actually worn down in the middle resulting in a negative crown...

    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    UPDATE: Tire off (only top is bad), wheel clean but "grooved" from running blades w/o tire (maybe they used tape of something else that was glued down): Wheel has many grooves where various blades wore into wheel to the point where the general area of the teeth results in a slight negative...

    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    Latest thinking: I'm tempted to build up some crown on the wheels using different widths of electrical tape and then use a flat urethane belt. For metal cutting snail speed, should be easier to half-a$$ something. (I know, I'm a cheapskate but then I probably won't put more than a couple hours...

    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    I've found SG on Amazon, but the Amazon search is garbage, "crowned" in the search is basically ignored so 95% of the hits are noise. I did find crowned on A but they were more money and didn't have any indication of the amount of crown.

    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    In that case, they sell crowned urethane tires would save the time. Have seen them for $75 on Amazon, but found them for $66 but check out this cross-section (!) WOW: Let's just say, I WANT these! LOL (still need to confirm the glue not needed - but then like I said, I won't put 10 hours on...

    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    From what I've read, the wheel is not crowned so you have to crown the tires. I was thinking just the cheapest but maybe someone might have a tip to save time.

    Walker Turner 14 inch Band Saw Tire Selection (sheet metal cutting application)

    Top tire is gone. I will not come close to putting 10 hours on this saw (I'm 70 and only small maintenance work now - NO projects.) Too many choices. All this urethane stuff, very little rubber. I'm thinking rubber since cheaper but maybe crowned urethane might be quicker? (wheels aren't...

    Precision machine shop friend said Sewing Machine Oil - it's really not that critical.

    Dumore 44 Tool Post Grinder Spindle Oil - Local Purchase of ???

    What would be a locally available suitable oil? (I've found mention that the Dumore oil is SAE 0W or ISO VG 5 thru 10.)

    Dumore 44 3" Lathe Tool Post Grinder

    It's rather complete. Bot 50 years ago and never used. Cord is brittle and needs replaced. Looking for local sale: Jeannette, PA 15644 (45 min east of Pittsburgh.) I think it's worth $400
