We needed a pattern to cast off of. With this we built up wood. We then put it in the lathe and turned it down to size and shape. We didn't have an easy way to design relief around each spoke hole as is seen on the originals. We decided to streamline the design a bit.

Once we got received the castings back we had to drill and then tap the spoke holes. We debated how to accomplish this with accuracy but without undue work. We thought about a rotary table but didn't have one readily available that was big enough.

We decided to mount it in the lathe and mark out spacing as best we could (it is an old tractor after all!). We then set the compound on the lathe and started drilling, after many passes getting up to the required 7/8" diameter holes so we could tap to 1".

Fortunately we had taken the time when we were at it to make the spokes necessary for the extensions when we were making them for the drivers, so that part was done.

Several cleats had be be removed as they had rotted out. A pattern was made and new cleats were cast out of ductile, then riveted in place.

We were lucky on the spacing. The spokes fit well. We had to drill the holes on one rim as the holes from the driver were at a different location in relation to the sides of the rim compared to each other. Lots of mag drilling accomplished this.

The depth of our compound was a little shallow, but spacers were made along with new connecting bolts.

Connecting brackets that attach the rim to the face of the driver were made off of a drawing of an original.

A great project right to the very end!

There's not a great deal of photos to reference how the extensions on the early 40's originally looked. If this picture (which is the earliest extension style I believe) is used for reference then the original spoke hole depth you chose might have been very close. Note the concave appearance on the extension spokes. It would appear that if the spacers were removed on your wheel and the hub centers were bolted down tight your extensions would take on a similar look.

The interesting question would be how did Twin City attain that concave look? Did they just build a "straight up" extension like yours and deflect the spokes upon installation? Or was the extension built with the spoke holes in the hub drilled at angles with the hub being offset to the center line of the spokes i.e. the spokes were concave from the start?

I woke up very early this morning and sat down and read through this whole thread again. All I can say is Wow what a job you and your helpers have done to bring this tractor back to life. not an easy task to say the least.
