Anyone know a store that carries spring scales for tape cali

[Beneficial]

I'm trying to properly calibrate and align my MCI/SONY JH110c tape machine and I need two spring scales... one to verify and setup the dancer arm properly and one to calibrate the pinch roller force against the capstan. The MCI manual says I need two spring scales meeting this criteria...

"Ametex 0-36 ounces (1.02kgm) and 1-10 pounds (4.54kgm)"

Anyone know of a physical store I could go to to get something like this? I want to finish up with this tonight if possible. I checked Ace Hardware and Radioshack's website but didn't see them selling these. Looks like target carries a 15 pound one so I guess that would work for one of them... not sure about the other one though.

Though you'll have to do the lb/kg conversion yourself.

Grainger and McMaster/Carr might have them as well, but they're machinist grade and painfully expensive.

Ok thanks. I check that link and it says none of them are available anymore through Edmund. I was actually hoping to buy them locally today in the Atlanta area today or tomorrow... thinking there should be some physical store that would sell them. I've heard fish scales work fine for the pinch roller force calibration... but I'm not sure about the more sensitive dancer arm spring scale I'd need.

They need to be pretty sensitive for that. I picked one up here:

Not a brick & mortar store; but maybe if you call they can point you to one.
