Hi,
I bought a taper attachment and after checking my saddle on my 10 year old Chinese lathe I found the back was not true to the carriage movement, so I decided to clean it up.
After truing the back up I got carried away and cleaned up the whole thing including the cross slide. I found the underneath of the cross slide was not true to the top which would make the nut sit at an angle. I am making a new nut for the taper attchment so no harm in making it a little higher to match the newly ground surface, though I had already shimed it from new as the nut was to high.
I did the grinding on my mill (horizontal) to get it good enough and then took to it with wet and dry using kerosene as a lube because water would instantly rust it.
Around the outside I used an end mill to clean it up and then wet and dry.
After it was all done I acrylic clear coated it and painted the red (rust kill) underneath. This way it will never need polishing again and has worked great on things in the past.
While I was there I bored 2 holes in the apron to add oil seals 22x 16 x 4mm to raise the oil level in it. I have found with the low oil level oil doesn't get to the top cross slide gear, now it will.
I also bored each socket head hole on the carriage to take covers and counter sunk the oil fill hole to take a allen head screw for the oil fill so it's flush and doesn't stick up.
The pictures speak for themselves, I was totally over it by the time I finished, but am happy with the results.
I showed my son inlaw and said I got carried away, he said look at your 4wd (which I totally polished all the aluminium, LOL)
Thats it's 10th birthday present over and done with,
Now just to fit the taper attchment where it all started.
