I think its time i lubricate my Edison Standard model A. I bought it 8 or 9 months ago, and it still runs well, but i think it can run better. I dont know how many times i must lubricate an Edison standard. I think it depends on how frequently i play the machine.
What are the parts that i must lubricate and How must i do that? And How can i gain acces to the engine under the bedplate?
I dont know much technichal details, so i could use some help.
You don't want the machine dripping with oil but regular lubrication will keep it running smoothly. basically you need to oil all 'metal to metal' bearings. These include both ends of the mandrel shaft and feedscrew, and the intermediate gear shaft. Also run a little oil along the feedscrew itself. You will need to take off the gear and feedscrew covers with a small screwdriver.
Oil all bearings in the motor, including the winding ratchet. Also drip a little oil on the shaft of the regulator and on the little felt pads on the Y 'yoke' which maintain the speed of the regulator. For oiling motors I use a nail polish bottle which has been cleaned and filled with oil - the little brush inside is perfect for phonographs. You may need to raid your wife/girlfriend/daughters' make up cupboard to get one!
Sometimes the gear on the end of the regulator shaft can be noisy, and it helps to put a little Vaseline or silicon grease on this. Just smear a little on wioth your finger, run the machine, and wipe off the excess.
The spring grease can dry up, which can make it 'crash' when playing. This can be cured completely by taking the spring barrel out of the machine, removing the spring, cleaning it and regreasing, but this is quite a heavy job and it is worth looking at other approaches first. I have found that if you pack the spring barrel with some fresh lithium grease while it is still in the machine this works its way into the spring and smooths things out without starting a dockyard job.
This all sounds like a lengthy business but only takes half an hour, after which your machine will run merrily for another year or so. Good luck

I have oiled the feedscrew, the gear shaft and other parts above the bedplate. I don't think i am going to work with the spring, i think that's too difficult for me. The spring is still good, and the machine runs very well.
Now i understand how i must lubricate my Edison standard, thank you very much!
Timo, you should also lubricate the bearings and the regulator/governor under the bed plate like Keith described. In order to get under the bed plate you first need to remove the crank, which is simply screwed on. Just turn it counter-clockwise until it comes off. Then you can simply lift the bed plate and work on the motor.
