That 7 is a real creampuff,a pleasure to work on compared to the late model Bulldozers.

Depends what STOODY product you are using, I use STOODY 101HC 1/16" with 75-25 gas@26v, 200a, dc reverse. If it was
.045 I would start at 22v 150a wire speed you will have to play with.
Good luck with it.

The manufacturer says to use 98% argon 2% oxygen. How well is it performing with the 75/25 mig gas?

Awesome rig and excellent work, thanks for sharing.

Hey Z, in my STOODY product selection guide it states 98/2, 75/25, or co2, the larger diameter wire it can be used with co2 or open-arc. I use 1/16" with 75/25 with excellent results.

That OTC 17 1/2 power twin looks familiar! Many moons ago first boss at the shop bought a set of OTC pullers: 17 /12, 30, and 50 tons along with an assortment of hand powered pullers. If I recall the full set including a couple hand pumps and one electric pump went for the outrageously high price of $5,000.00! Yea that was a few years back!

Started ripping this 135 down today, replacing every pin and bushing.

That 17 ton is nice and light to use on these small machines.

Those machines look too new to need line boring. We're they never greased?

SSSHH! If someone finds out about what a grease gun can do Tom will be out of work!

 

[TOM V]

The 135 has 5000 hours on it and we'll lubricated, the 85 has 1180 hours on it and also well lubricated, these things start out with excessive clearances and poorly finished parts = prematurely loose machines.

So rather than lack of grease it is the excess clearances both letting grit get in to act as a grinding compound along with the slop hammering the metal out?

 

[TOM V]

Exactly Ken, pounded out.
