I am consider replacing my Delta 14" tires with urethane tires. I have tuned
up the saw a number of times, wheel alignment, balance, planer alignments,
etc. But recently it has started to vibrate more. I don't see how the mass
of the wheel or imbalance on the wheels would change, the bearing seems
tight with no play, so I am thinking it's the tires. FWW had an article on
Tire Replacement in 92, but seems like it was before Urethane tires. That
article goes into extensive detail about the pain of properly crowning and
stressing and balancing new tires, seems very excessive to me. All the ads
on the Urethane Tires suggest they are plug and play.

Has anyone used the Urethane replacements? How well did the go on and how
well do they work?

I put urethane tires on my Grizzly bandsaw a few years ago. As I
remember, I had to heat the tires in a pot of water on the stove to
get them soft enough to stretch onto the wheels, but it was a fairly
painless process. Nothing to it really.

I bought some urethane replacements for the chiwanese 14" bs and the tires
were half the thickness (like 1/8" vs the rubber tires 1/4")(not width) of
the existing rubber tires. That created 2 problems for me- moving the blade
in, in relation to the bearings and effectively shortening the blade needed
for the saw. Seeing as the blade was close to being too long to begin with,
caused me to have to shorten the blades. I said the hell with it, put one
urethane tire over the other on the top wheel and put the rubber tire back
on the bottom wheel(added some contact cement to finalize the positioning).
Works fine. Try to verify the dimensions of the urethane replacement are
close to the existing tire before you buy. Pat

Did your wife complain when you dragged the bandsaw into the kitchen?

Hey Orbit,
I have replaced the tires on three Delta/Rockwell 14 inch bandsaws and
the procedure is simple yet it is important to heat the tires in water
(not boiling, but as hot as you can get it without hurting your hands)
and stretch them on the wheel. Having the wheel off the saw is the
best way to do it so don't hinder your operation by trying to do it
while mounted- you won't be saving any time. I think you will be happy
with their performance too.
I got my tires from Iturra design in Florida. Lois Ituura makes his
own tires from stock and he does a great job fabricating them. When I
checked tire prices Iturra was charging more for neoprene tires than
urethane. I ithink the cost of neo is on the rise.

Your saw may be suffering from tire wearout. On one of my saws I was
able to see daylight between the lower tire and its wheel (at the
topmost portion) when it was under power. Cut off the power and the
tire returned to the wheel. It was loose, but I did not realize how
loose it could be. Obviously the blade kept the tire presed against
the wheel but with no blade contact directly below the table the tire
was able to float away.
Repost if you have any difficulty, or better still, ask Louis for
advice on mounting the tires. He's a wealth of information.

Good comments from all. It sounds like from these posts it is worth the
investment. I just hate to spend the bucks and it still vibrate the ones I
have aren't showing any grooves or cracks, they see fine. I will look at
the Iturra's.

Was it like that from the start? There was a short period during 1989
when bandsaws left the factory with tires that were off durometer
spec. and would "lift" at operating RPM. Issued a tech service notice,
thought they were all replaced.

A close friend (Chemist who worked for Cooper Tire in Tupelo), helped
me to resolve the problem, changing the chemistry of the rubber. Not
many years later, the tire changed from natural blend to full
synthetic.

How come they tested good before leaving the factory? Maintenance guy
changed the pulley at the test station when the set screw would not
hold. He thought it was the same size, but slightly different.
Changed the rpm by 5%. That apparently was the threshold, good at the
test station, lifting in the field.

just goes to show you that a little mistake can create a big problem.

Hello Frank,
Thanks for the comment about tires off spec. No, this was not from
the start. The saw I noted "tire lift" was a Rockwell unit from the
50's. I do not know if they were the original tires but they sure
looked old. Hey by the way, do you know if the older Rockwell 20 inch
bandsaws ever used rubber tires? I got one with TEXIN tires and was
thinking about rubber when it comes time to replace those. Thanks in
advance for any comments,

Marc

I'm not entirely sure. During my tenure the wheels were sent to a
local fab/machine shop (Transport Trailer) where the tires were
bonded to the wheel without flanges and the wheels were machined and
balanced. I believe during that time they were always synthetic.
That goes back to the mid eighties through when the units were
discontinued, around 2000. I'll probably see some "oldtimers" at the
end of the month, I ask them.

I just purchased 3 of the tires and have not put them on yet. Mine are
only 6in. in dia. However I rec'd a pamphlet from the company and it
said that some vibes are caused from the drive belts. Check this Co.
out as I find them to be very helpfull and cost effictive. Sulpher
