Thread: pick ya brains

I've seen discussion about and/or ads for replacing the rubber tires on bandsaws

have you tried a google search ?

Hey texx,
meat cutting bandsaws were designed to be hosed out and cleaned everyday, hence no rubber,
if there is enough metal on the wheel rim its easy enough to take them to a machine shop and have them turn a recess for you, should be a quick job and not cost too much

yeah there probably is enough there to get a slight recess machined into it .
but i dont think there is such a thing as a cheap machining these days .
i have found some stuff on gluing inner tube rubber on the wheels since i started this thread might try that first

They need to run on a convex (domed) surface or they will run off line.

yeah i know they need a domed pulley thats what keep's em on , same as the flat belt pto pulley on my tractors.
and thats a good reason not to machine the pulley i think i will just try and glue some rubber on it

Hi Texx,
take care of what thickness of rubber you are planning to glue on as this increases the diameter of your wheels. The blade will be in a slightly wider position in the table insert and unless your top and bottom blade guides have sufficient side movement, correct adjustment might be difficult or impossible.
A new machine from Santa might be the other answer.

yep thanks never thought of the blade guides.
and santa wont be coming anywhere near me im afraid

Gluing a cut-up inner tube to the existing wheel should only move the blade over a couple off mm at worst. It's not like you're gluing on a cm thick tyre or something.

If your insert or guides can't handle that little deviation... [shudder]

Assuming the blade runs centred on the crown of the dome then it shouldn't be taking the set off your blades - unless the set of the teeth is greater than the curvature of the dome or the blade is over-tensioned to the blazes. I'm wondering what sort of set meat-blades have, if any?

Regardless of "shoulds" & "should nots," I'd do as you plan and glue on a section of inner tube. If, after running it on rubber for an hour or two, you inspect the rubbers and see gouging where the teeth are chewing out the rubber then you'll know that your suspicions of it flattening the set are correct.

If so, this is also correctable with a little effort. (eg. removing the rubber, gluing on a 1/2" wide strip along the crown and then replacing the rubber.) But knowing it's a problem is one step further along the line than suspecting you have a problem.

FWIW, I reckon you're on the right path.
