The slot in this steering gear case is messed up. Right now my only real option is to repair. I tried brazing but the brass just beaded up. What about installing pins at the end of the slot? Or I could just get rid of the long pin in the spider and with a short pin. The one end is stepped the other has a nice slope to it.
Sorry got to use photobucket, the smallest my camera will do is over 600MP
Give me a call, I have some!
Mark, if you must repair it 'in situ', I would suggest you use a dremel tool and burr to make the grooves good. Then make a brass inset to fill the void each end, and silver solder them into the groove. You will require less temperature for soldering and reduce the risk of distorting/ melting the brass gearcase.
Hope this helps.

It may not seem like it now, but it would be a whole lot easier to remove the case, put in a good one (Dave Huson just mentioned he has one) rivet it and repaint the column. The biggest pain is removing the adjuster rod ends so you can remove the control rods from the column housing. Removing the rods from the gear box isn't too bad; there are a bunch of posts in the past on how to anneal the brass so you can bend it.
If you remove it for repair you'll go through the exact same removal / installation process, but you still have to deal with the repair. If you know someone good at welding brass they can do it; if someone doesn't know how they can really botch it up. So you'll probably pay someone for the welding, then the machining....... Be a lot less expense to buy a good one.
Your late gear case looks normal to me.
The T steering is anything but precise! That long groove just provides a path for the long pinion and to provide a stop for it. The pinion end doesn't glide on the groove.
Here is a late case on the left, early 4:1 case on the right. Note the long '24-up 5:1 case has groove similar to yours.
It's for a 26/27 so I think I will go with cleaning it up. Thanks for everyone's help. Someone in the past may have swapped the cases out and installed an early version.
There I learned something new!
mark, note in dans photo the cover on the left is knurled all the way down, thats 26-7, and the cover on right is only knurled near the top, early case
Covers are interchangeable! It's a mixed bag as it is but the sun gear is the small one and the gear plate is marked with a 5.
