Makes sense to me!Because the grinder is set up for the proper taper angle I decided to get making the missing gibs for the dividing attachment overarm. One is about 100mm long, 3.5mm one end and 4.5mm the other (I measured the end gaps with a thin tapered wedge painted with magic marker). The other is about 235mm long.
I started with the small one, found some 3/16" gauge plate and milled the edges to the 55 degree angle so they fit in the dovetail. Didn't get any pics of that sorry
Then I ground in the taper with my surface grinder. As expected, it bent.

Now being a steel gib I could have just based it flat but I thought I'd have another go at hammer straightening. It's steel and a lot thinner so took a bit more but it worked just as well.

As it happens, grinding the other side bent it the other way so I kept flipping it over and grinding each side a bit until it was the correct thickness and more or less straight.

Here it is inserted in the tailstock. Tomorrow I will decide whether to try to add on the same adjusting collar as the slotting head gib had or just use a collared adjusted and slot the gib. Probably, I will just slot the gib so it doesn't get all messed up by welding or brazing.

Here you can see ehy you make them over-length. It's easier to cut them down to size than it is to re-make one because you over-shot the mark.
