Bandsaw tires (And it's on topic!!)
Just got a small vertical walker turner bandsaw for free. It's a well
built machine of probably 50's vintage but hell...could be older or newer as they don't really change over the years. Anyway, I believe the thing was originally intended as a wood bandsaw but currently has a metal cutting blade on it. The tires are cracked and beat to the point of being useless. Wheels are about 12" dia (haven't even gotten it out of the car yet). My horizontal saw has steel faced wheels with a flange to keep the blade from slipping. I'd like to set up this smaller saw for metal cutting also. Any recommendations concerning the tire problem? Re-rubber or should I figure out a way to use a steel faced wheel with flange as the newer horizontal uses? Any recommendations as to a good generic FPM speed that I should shoot for to cover average cutting needs? Any ideas would help Thanks, Koz |

The very best tire solution I have used is to make tires from a silicone
rubber that I got from a heat-seal blister packaging machine supply co. The rubber came in sheets and I cut it into strips and contact cemented them to the wheel. The rubber has outlasted factory tires 10 to 1. "Koz" wrote in message ... Just got a small vertical walker turner bandsaw for free.

Anyway, If MSC or J & L or McMaster-Carr can't provide a tire you can make one yourself out of 1/8" thick rubber sheet. This should be available at a local rubber or belting supply. The rubber can be glued on with epoxy. I bought a used saw and the previous owner had done that to the saw. The rubbers are still on. Here, McMaster-Carr has these wheel rubbers: 10" 4561A31 $16.18 12" 4561A11 $16.87 14" 4561A12 $16.72 All 1" wide. Call 'em at 732-329-3200. Tell 'em Eric sent ya They're on the web too. ERS |

My 14" Delta wood/metal saw appears to urethane tires. Anyway, they are
tough and 7 years of cutting 98% metal on it has yet to wear the tires in an significant way. Resilient tires give accurate tracking with different blade widths and tensions. Anyway, you can get tires made from rubber or urethane plus a multitude of band saw accessories at http://www.carterproducts.com/produc...id=6&cat_id=15 Randy "Koz" wrote in message ...

Often you can turn the old tires down on a lathe and get a good new
surface. One alternative is to make tires from an innertube. Cut a band which is wider than your wheel, but smaller in diameter. Stretch it around the wheel evenly, then insert dowel pins or other spacers evenly around the wheel between the tire and the rim. leave spaces between the dowels. coat both the rim and inner tire with contact cement. After proper curing, remove the dowels one at a time from oposite directions and stick the tire to the rim as you go. When the cement is cured you can trim off the excess tire with a stanley knife. (OR, you could buy some tires,). Either way, its best to true up the old surface first, a lathe being the easiest way. Paul |

I bought mine for $9.00 each from Memphis Machine & Tool.....they are
a rubber, and so far have worked fine. Maybe when they do wear out I'll try the urethane, but from what I have seen over the years rubber lasts quite a number of years. I certainly would not machine a flange into your wheels a a horizontal bandsaw is a totally different machine than the verticle. I can't say for sure but there are tons of metal cuttin g vertical bandsaws out there and I have never seen one with flanges to retain the blade. They all use adjustable guides. You can cange widths on verticle bandsaw blades to accomodate different radius in cutting stock but normally a horizontal takes one given blade with as its just used for cxutting straight cuts, no curves.

Thanks for the link. As you and others have suggested here (and the
question I was really asking) was that rubber/urethane hold up under a load of metal filings. I'll go ahead and true the wheels, replace the bearings, and probably re-tire with urethane. Thanks for the help, everyone Koz (who had to get the kick in about the free brand new drill press and table saw that he got in the same deal) Randal O'Brian wrote: My 14" Delta wood/metal saw appears to urethane tires.

If you are want a reason to fire up the lathe, you can make your own.
I make them for a 1/6 scale T34-85 tank RC model project. http://www.geocities.com/eastpac01/rubbertires.html Rusty Bates Koz wrote in message ...
