Did some preliminary assembly last night.
What do you all use to keep the bare metal parts from rusting again? I live near the ocean and this lathe will not be used. (maybe a few times a month) Besides coating everything with oil and covering the lathe what other tricks are out there? Really questioning if i should have all the hardware plated. that would leave just the gears and ways unprotected which oil should solve.
OK.....
Getting ready to put the spindle back together. Man how i wish i took better notes and pictures. I was relying on the factory parts book as my guide but when it comes to the spindle it is not detailed enough. Thought there was a cross section in there but it is the QCGB.
So, the spindle assembly. Lets figure this out step by step.
It is clear that bearing 0674 goes into the headstock with the clip facing out. That bearing therefor has to press onto the spindle first. Don't forget to only press on the inner race. Otherwise you will damage the bearing
The question is the grease seal. (LA-672) i think it presses to the outside of the nose of the spindle. (Just behind the chuck thread) How far does it go on and i think this can only go on after the spindle is installed and the nose bearing cover is installed. (LB-3)
Install the rear bearing "C" clip. (0931)
After the nose bearing is installed, pass the spindle through the headstock front and slide on the following in this order:
Bull gear assy. (LB-4)
Spindle Pulley. (LB-5)
Belt. (LB-6)
Spindle Gear. (LB-10)
Collar. (LB-11) (Leave set screw loose)
Spacer. (LB-17)
Belleville Washer #1. Concave toward nose bearing. (LB-16)
Belleville Washer #2. Concave toward tail bearing. (LB-16)
Press or otherwise install the nose bearing into the housing and install the nose bearing cover and screws. I expect this to be a transition or slip fit. (Now comes the grease seal????)
Next is the tail bearing. bearings should not be double pressed. Since there is a take-up nut coming next the bearing cannot press to the shaft but could press to the housing. That would be interesting but since i did not press this bearing off i expect this to be a double slip system.
Once the bearing is installed then comes the Take-up nut. (LB-12)
The million dollar question how much torque the take-up nut requires.
The other question is how tight should the belt be? I have always thought the belt was too tight. I realize you can adjust the through on the motor tensioner but in general how tight should the belt be? I have seen them tight and what i would consider loose. How much up/down should a properly tentioned belt move? (One side)
Recap...
Where did i go wrong in my figuring?
How do you protect your bare metal?
What is the take-up torque
How tight should the belt be?
Teaser.... The post office dropped off a couple of packages last week. One was about 30" long and the other heavy with very dirty content.... I will more than likely start a new thread for that.....
