erco/marchant shrinker/stretcher
 
Hello,
Just got a erco shrinker & stretcher 6" 1 each and also a 12" 12a marchant (1) with currently only a shrinking die in it. I may keep all but am considering keeping just the erco's that are set up or maybe keeping the marchant and getting stretching dies for it. Any thoughts? The marchant is phuematic and a dream to use. The erco's are kickers.
Thanks,
John

What are you asking for the 12a?

john hobbs 06-15-2018 04:29 PM

Not sure If I'm going to sell any of them. Looking for opinions

Welcome to the site John.


The Erco's are good for hand work. You can 'kick' it or 'toe' it for different results.



The Marchant is a beast. It will shrink heavy stuff. Pretty hard to finesse a shrink. If you can stand the price, I'd keep them all. I have to manual Marchant type machines and they are amazing.



What kind of work do you do?

thanks kerry,
I restore classics. You're right about the finesse, might be an overkill for 20 gauge. I'll try to upload a photo.

I've actually never used a 12. The pneumatic Marchant I have used was Dutch Comstock's. What I remember is that you set it for a given shrink and that thickness is what you get...want it or not.

John, a Marchant, air or kick is a better machine than an Erco 1447. The adjustment wheel is a great feature. But as pointed out the Marchant 12A does not creep up on something. You can wind back the adjustment and lighten the pressure on the dies but eventually they get to the point where they slide. The only downside of 1447's when they have been used a lot is that with heavy wear you end up having to kick way into the machine to get it to shrink. Easy to shim the function back.



If you ever plan to take an Erco apart note that the pivot pins are locked in their bores with set screws. The catch is that there is a locking set screw on top of the pin retention set screw.

Kerry and Rick, thank you for the information!

Hi John,
I also have ERCO and Marchant machines.
And, like others say, the Marchant is for working heavy material - .090" and up.
The ERCO 1447 is designed specifically for aircraft sheet - .016" to .090".


We sell parts for the ERCO 1447 machines and service and rebuild them.
We also sell various hardened "compensator" plates (.135" and up to .375") to adjust the kick arm forward in the machine.

Hi Kent,

Thanks for your response! Good info, I appreciate it.
I'll give you a shout,
John
