    If I may suggest next on your list is a quick change toolpost which you can purchase from Adendorff which includes 4 lathe cutting tool holders, and if you need more, which you eventually will, you can purchase the individual holders from banggood.com..
    Marco I dont think you have enough tool holders. Thats a nice option to be able to buy cheap holders.
    The dickson type tool holders I have are very expensive. Like R1600 each so its important to choose wisely.
    Looks like you have a dro on your tailstock. Cant quite make the picture out.

    Yep, but the Dickson type are worth every penny, I just truly cannot afford that high end, nor can the poor quality of my work justify that..

    Some time back I made a new tailstock quill as the original had a ton of slop, also wanted MT3 taper as all my milling fixtures are MT3 and I thought that would be good for interchangeability, pretty pointless, but it is what it is.. Since I had no means to engrave measurement markings on the new quill it was easier and cheaper to employ the use of an old digital caliper, not exactly accurate, but works just fine for my needs..

    And, yes, contrary to my previous statement, the tailstock is filthy....

    I need to make a quill for a southbend but have been procrastinating as its a bit of a daunting task. What material did you use . Theres so much taper in my lathe it would be hard to hit the quill dead nuts on. Thats nice your tailstock.

    Plunger it was some time back so I honestly cannot remember, I think it might well have been EN8.

    Truthfully its not perfect by a long shot, but much better than the original.. I turned the quill between centers first slowly adjusting the tailstock until I had no taper, but in truth I now have gotten to the stage of wanting to redo the exercise, first by line boring the tailstock housing, and then manufacture another quill, but the line bore thing has me sweaty with anxiety..

    I recently got my first lathe (a 1980's Taiwanese clone), and despite trying to hammer into my brain to not leave the key in the chuck...

    This was my first "upgrade" to the lathe (but I see your lathe has the chuck cover which I think acts as a safety switch to ensure the key is not left in the chuck):

    @Marcochezzi, awesome idea with the old vernier caliper!

    I'm sure my chuck cover will be one of the first things to go

    I need to re-do the wiring anyway (well the terminations that is), as it is a 3-phase machine and I need to install a VFD. Then I can just disconnect the chuck cover micro switch...

    Marco, what size toolpost holder do you have?
    I have the 12mm one from Adendorff and would like to buy some extra toolholders.
    Please can you share where you bought them from.

    Thanks

    Nice lathe Sinwolf, congrats. I wouldn't sweat the gearbox oil too much - heat and contamination are what break down lube oil. If it's clean and never been overheated it should be just fine despite having been there for a few years. Light oil in the chuck. I use the Spindle oil from Adendorff to lube my lathe and mill, seems to work just fine.

    Quick change toolpost is pretty much essential if you are doing some serious work on the lathe.

    For quills, EN8 is good and you can get it nitrided if you need it hardened - should not be necessary.

    Thanks
    Woolf I think its 16mm, I'll confirm a little later with pics for you, all purchases through Banggood, its exactly what Adendorff sells, I will send you a link image as well for your holders, please bear with me, busy billing + year end...

    Please do not remove the chuck cover, you will need it when using coolant. As for cleaning a chuck just wind out the jaws, clean them with a tooth brush and paraffin then do the same by winding the scroll and applying the brush.

    To be honest, I do not have a clue... But there is a lot of threading options...

    One thing that is a first for me... The thread dial indicator... All sources I have read on the internet recons that this is to be used for IMPERIAL threading only... For metric, you have to keep half nut engaged. This lathe is the first lathe I've seen where the dial indicator is actually used for METRIC threads... The dial indicator even comes with 2 additional "change gears"...

    If your lathe is imperial, then the above applies, if the lathe is metric, then the opposite applies, where the half nut can be disengaged for metric threading, but remains engaged for imperial..

    So I am led to believe, mine is imperial, and I honestly wish I had a metric solution, because the functionality of engaging / disengaging the half nut when cutting threads is very practical, well for me anyway..

    Either way, both imperial and metric threads are very doable, no stress..

    With regards to the half nut disingagement. It doesnt matter if its imperial or metric but sometimes you just have to leave it engaged. Im dumb with maths and machining but on my lathe I dont think I can use the thread dial on imperial. But my lathe is metric so if you have a metric leadscrew of 6mm you can disengage the half nut on anything that can be divided by 6mm So take 6divided by 1,25mm it doesnt go so then you need to keep the half nut engaged otherwise you loose your thread sequence. i havent bothered to see what happens if I try using the thread dial because modt threads are less than 15mm and honestly its so quick to just put the lathe in reverse to travel 15mm its no skin off my back.

    I have a thread dial but dont need it in reality.
