[GreenKeys] Model 15 casting repairs (JB Weld?)

[Nick]

To me, JB Weld is nothing else than a strong adhesive - good for a temporary and cosmetic fix.

Any cast metal can be welded with the right material and a very experienced welder will get the job done no matter how difficult the task will be. The downside is he will charge a minimum of  $100-150 an hour - no matter how short that hour is.

Long time ago I had an antique cast iron kitchen stove with a broken corner. The guy used some special magnesium rods and did a fantastic job - almost invisible. The welding scar was only 5 inches long and my wallet was  $100  lighter.

Hi all!

As mentioned in an earlier posting, it is really
sad when a base or frame fracture/breakage
happens to our treasured machines...

I had an almost mint condition M26 base broken
completely in half, despite the shipper ensuring
the machine had been very carefully packed...

It had been quite obvious, the carton had been dropped
from a height on its' bottom edge to inflict such
damage...

More to the point, shipping damage is by far, the main
cause of damage to equipment...

Back to the topic of "JB Weld"...

I had considered trying to repair my fractured base
on the M26, but wasn't sure if it cud handle the
stress and operational vibration etc...

Another problem is the base casting is so thin,
I don't. think it can be welded...

I am going to have to re-visit, and re-think the problem...

It wud be nice to hear from list members of their
experiences with JB good and bad...

Perhaps now with advances in metal epoxy products,
a better solution may be available

When I worked in the Teletype shop many years ago,
I had encountered several Model 15 typing unit
frames, (Legs) that had been successfully welded...

What say you all?

Cheers!
