Here we go again!
This is the start of a longer feedscrew for the compound slide on the 7x I am rebuilding and, again, it is from 17mm O/D silver steel, starting with an offcut from a prior project. I have left it "in the lathe" as it were as it is safer there than anywhere and it means I do not disturb the concentricity should I need to turn the section down further before running the die down it.
Why longer? well the original feed screw is not the same length as the compound rest for one thing, for another, I am carrying out the obligatotry "add bearings to this b*tch" mod and needed a longer end on the dial side, so why not make the screw section the correct length whilst I am there?
Plans are all done, now I just need to knuckle down and do the work.
Yes, I still have to complete the cross-slide feedscrew, but I am waiting on a tap and die (7/16-18 BSF R/H split die and 3 pc tap set if anyone is interested) as well as some stock (brass hex and steel round) )to arrive so that I can finish that and in the meantime, I want to keep the momentum going on the work that needs to be done.
I have all of the required stock required for the compound screw mod since that is only a section of aluminium plate, bearings and the silver- steel for the new feedscrew but again, I am awaiting a die to cut the threads (3/8-20 R/H split die). Whilst I could do this single-point, I prefer the use of a die for things like feed screws and that is just my personal preference. Once the threading is done, I will then be able to concentrate on the (easy) remainder of the work.
It may be noticed that the lathe is slid backwards and not bolted down. Simply put, I move it forwards, bolt it down, use it, unbolt it, clean up, clean the lathe and slide it backwards.
Here it is in "stored" mode...
Yes, there are two saddles on the bed... The one on the right is the one for the lathe I am rebuilding. It is easier and safer to store it sat on the lathe than anywhere else and it keeps it where I can easily get to it. It is a wierd sight at first, but to be honest, I actually find it rather amusing.
As an aside, some may have noticed the "circle" on the top of the compound slide riser section on the compound for the lathe I am rebuilding. That is is about a mod I want to do, but will need access to a mill to complete since my milling slide/vice/compound setup is not rigid enough for the task and the slide is just over the maximum swing of the 7x.
