Thanks for all the info and help!
I have stripped the lathe a few times now and lapped and reassembled but nothing really seems to help the binding issue.
If i get it right in the centre of the bed the cross slide is extremely tight close to the head and tailstock ends. So right at the extremities means it is very loose in the centre of the bed.
This means that when engaging the auto feed the whole cross slide assembly twists slightly, thus the first part of the cut is deeper.
I was also trying to get it to work without the cables
I disengaged them and engaged the split nuts and added a handle to the end of the leadscrew.
It proved almost impossible to turn the leadscrew and move the carriage.
When the handle was turned it had to be turned really slowly and carefully to prevent the gears from catching in the gear housing.
I am not sure why this is happening.
I have gone through the lathe book a few times now and the only difference i can see is that the cable system was added as an extra for some reason.
If it is removed it should function like a regular Gingery, correct?
It is a work in progress and i am having a lot of fun doing it!
What size motors do you guys use?
Mine has a 1/4HP in it ad it feels a bit underpowered.
Looking into a variable speed DC motor and some other options too!
Hope you all had a fantastic Christmas!!
My hands are still black from grease and such!!!!

> You are a lucky person to have come into possession of a machine that has been homemade and yes a Gingery with a few modifications. What I see is the same style of movement that was very common on boats and some watercraft. Cable is a very basic form of moving something from one place to another. It was good to see the pics. The person had no training when he made that machine just basic shills and the want to. If you look on the bed, you will see a lot of dings (witness marks). They tell of a person that had things dropped and thrown from a chuck or face plate. The cable was one of the easiest ways to solve the problem of free movement of the carriage. The other way would to replace the cable with a rack and pinion. But if it were me and it works the way it does, leave it. A real nice find and hope you enjoy it as much as it's maker did.

Anyway you should be able to sort out why yours is binding by reading the steps in the book and following the build sequence! I wouldn't start scraping or removing material until you see the trouble as it is easily made worse if you are not getting a flat & parallel method to your madness! I would mount the lathe to a dead flat surface to be sure your bed is not racked as a start then blue things and figure out why and where it is not true!
