Default Pexto 132 foot shear

I picked up a Pexto shear tonight. I`ve never seen one for sale overhere, it was an hour drive and the price was good so I brought it home.

Capacity is 18# but I`ve also seen the rated at 16# Can anyone here tell me what the difference is? Maybe the cutting angle? they look the same to me...

I get a pic or 2 tomorrow. I`m pretty happy with the find

Many tools are underrated so people won't break them.
Sounds like a great score.

The thing about a '39 Ford pick-up is that that ugly grille kinda' grows on ya' after a while.

Not taking anything too seriously.

Congratulations, dutch!

Just thinking out loud: Since 16ga is 15% thicker than 18ga, I'd imagine the cutting blade is the limiting factor. I've abused brakes and shears. Deflection is the problem, so I'd think the same machine rated for 16ga would have a heavier, stiffer blade and probably a ratio increase.

I'm with you Bama, I'm really waiting to see the pictures of a 132 foot shear. This tells you how much I know about shop tools.

Bring it on Dutch.

yes, deflection always is. I`ve no 16ga shear to compare. I cant image there would be any difference in the castings but heavier blades could very well be the case. Also this shear does not have a hold down for the panel. I`ve read this was an option but maybe it was standard equipment on a 16ga shear too.
I`ll tear it apart in the next weeks or so for inspection and adjustment. Maybe it will reveale a thing or two.
I`d love to see the 132ft shear too...

So would I! I've done a lot of work on shears in my previous life - I'm guessing it's an oldie, so it's likely well built (heavy!). I'd advise getting the blades ground while it's apart, a good inspection and set up of the gibs (make sure they are not worn and able to be set up to spec). I'd check the blade beds for warpage while it's apart too. You may have to shim to get the blade gap consistent all the way across. Blade gap should be set to about 7% of what you want to cut.

I found some literature.

"Holddown is automatic, spring actuated. Standard equipment on all sizes except Model 132."

thanks for those links Doc. Printed the adjustment specs and I`ll be looking out for one of those catalogs ...
I love that old paperwork.
I cut some pieces of 19ga and I`m already in love with this little machine. Looking forward to getting it back to top condition.
