Well done. That repair will last many years as long as plenty of slideway oil is used. I bet there are many Bridgeport owners who would like to know you could cut a bit off the gibb and screw.
I repaired our Bridgeport by adding a bit on the end of the gibb. The only thing you have to take care off, is the joint of the bit added, must not fail. I T.I.G. welded it using Nickel wire.
I have a Bridgeport in my home workshop. At the moment in bits. I have had the slides and bed reground a very expensive job,The gibbs alone cost £200, but I would not have been able to reset the gibb as much of the wear was in the middle of the travel.
The problem with many machines in a working environment is the lack off lubrication. The one-shot lube system is great if you can get the operator to use it. Thats why many new machines have automatic lube systems electrically interlocked with the on/off button. We in our home machine shops can be generous with the oil
