The problem with welding and then machining without any post weld heat treatment is that the welded material often becomes harder and is therefore more difficult to machine particularly on a light duty lathe such as a mini lathe.
Another alternative method is to reduce the diameter of the shaft where it was splined, make a seperate new splined bush and then fit the bush to the reduced diameter and weld in place ie no machining of welded material.
Hope this helps,

You are now spoilt for choice .
