Repairing a Landis 25 5 in 1

[FDC]

Had to have on of these to go with my refurbished Model 12 F. 

The chassis casting was broken. I repaired it using a broken cast piece from an ancient Taylor spot welder then I welded it using cast iron rod and my TIG welder. It came out better than I deserved. It’s in prime as of this evening. Excited to have it all together. Have to make a couple springs for it still…

Will I ever work leather? Not if I keep buying cool vintage iron machines!

Half the fun is the acquisition and road trip to pick up these gems.

As a machinist and welder by trade, I have to say that is some OUTSTANDING work!!!

 

Can hardly tell it was ever broken.

 

Side note: I would do almost anything to have that knee-mill!!!

That's some fine work. Outstanding job repairing it.

Impressive work!
I bet it is flatter in the bottom now than it was when it was new :-)

Outstanding job. As an ex fabricator/welder I know how difficult it is to weld cast anything. 

In the days before mig I worked in a place that repaired cracked engine blocks. They would build an oven around it with fire bricks and gas jets. Leave it burning overnight till cherry red and two old boys would sit on an upturned bucket, stripped to the waist and set to with a really long oxy torch wrapped in asbestos and wire and cast rods as thick as your thumb. They had a bucket of water to quench the  torch in. Amazing.

Thanks! I certainly have had welds not turn out as sweetly. A lathe and a knee mill will get you a lot of places won’t they? I’m fortunate to have this one for sure.

Of course I did this on the hottest day of the week! I’ve seen some of that engine repair work that you mention, intense to say the least. I pre-heated with a torch and post heated with a heat gun set up. No fatal “tink” heard. Yet…

People often think they've  done it but they  don't notice that hairline crack running alongside the weld that tells you that the crack has just moved from where it was to where it is now.

So, @FDC, I'm curious why you'd go to the time and trouble of matching up the curve instead of making a straight cut across the stand and making a straight cut to piece it in.

It's great work, but it seems like it was a lot of extra time.

Truth is it’s way faster to clean up the fractured face than make it straight in this instance. The curve also had more surface area to weld which is stronger. Once I had milled a piece of old cast to use it took me less than 10 minutes to sand the casting fracture and profile the filler piece and bevel both!
