Bar Tender Please

Looks expensive. Never bent a bar myself but it seems the tool may cost many times the cost of just replacing the bar.

(maybe they can slip in a few STIHL depth gauge tools when they ship it?)

Photos?

No photo but I went out to the truck this morning and dug it out. It was cast by Librande Enterprises in Idaho.

It’s mainly for doing harvester bars at 32” long they’re roughly 100 each, our last machine ran 3/4 bar and chain the was roughly the same length they were 4 times the price.

Fairly easy to make for someone with a few tools and basic skillz

Probably not for a casual user as much as a shop or company repair department. As noted, harvester bars get expensive.

I like the log splitter idea!

The problem with the vise is you can’t hold the bar in 2 places and apply pressure in between. You also can’t go beyond center at the bend allowing the steel to relax back afterwards.

Actually I can with my 24" end vise and three 6" lengths of hardwood:
For a deeper bend I just use thicker lengths and/or change the distance between them.

Hey, check this out for straightening bars

I manufacture these.

had to straighten a bar the other day after riveting a new nose on. put the bar on a 2x4 in the hydraulic press. minimal effort on my part.

I manufacture these BARTENDERS

I manufacture these.

Welcome to A.S.!

What kind of things can you tell us about them, that only the manufacturer might know? How they were designed / evolved? 'Tricks' on use? Any other interesting stuff?

Thanks.

I used two trees close together to straighten bars.

I couldn't find two that close, so
I used my log splitter and a couple 2x4's to straighten mine.

Anyone got any suggestions on how to straighten low-end consumer laminated bars? I have one that has a small (<1/4") bow along the whole length of the bar. I have tried the wood block and clamp method and have gone considerably past straight in the opposite direction but the bar always just springs back to its bowed shape. This must be much easier to do on solid bars.

I use a hammer or a vise and a bigazz wrench to straighten bent bars. @SteveSr try putting a 2x4 at each end of the bar and use a hammer to beat the bar in the middle. Sometimes a "shock" works better than pressure.

On laminated bars, the layers can move independently, and shear the spot welds. Try it, but the results may be different than with solid, one piece bars.
