Re: Introduction


 

Hi K;
First thing, assuming the machine has its original plate on it a machine of that SN should not have that bobbin holder. The appearance underneath the machine does indicate an earlier machine. That holder is a foldable one, if you push the loop on the end of that curved spring in the back off the pin it fits on the ring then the upright ring will fold back. As Anthony stated this is the bobbin holder from a very late #8 or a very early #9. All the earlier #8s used a larger diameter bobbin in a plain case without built in tension. The hook is different due to the different size of the bobbins so this likely accounts for a good bit of your rattle. I am posting a link of what you holder probably looked like. It could have used the still earlier one in which the upright did not fold back, but I suspect this folding one was in use by the time yours was made. You can see the tension adjusting screw with the knurled head & the plain bobbin case with no tension spring on it.?
Incidentally on most of these machines the SN is stamped into the cast iron ledge the right slide plate seats on. If you slide off this plate you see should see the numbers stamped in the front ledge in single file. In the direction in which the numbers are upright read top to bottom.?
As to the presserbar the tension adjuster serves as the upper bearing for the bar. The adjuster is thread for a close fit to the head & the ID bored concentric for a close fit to the bar. As you turn the adjuster you should see no movement of the bar at all. It was also bored in line with the lower hole for the bar through the lower part of the casting. As Anthony said this is fixed there is no adjustment.

The presser bar is not the problem. The presser bar is not meant to adjust left or right. The regulator is designed to be a thumb screw type adjustment and a oil cup. The other ones are just oil cups as well. Sounds like adjusting your needle bar will solve the needle rubbing.

In regards to you bobbin case, your photos show you have the late No8/early No9 case and holder. This type of holder is loud on my No9 as well. You can adjust it inwards as Miller stated. To insure enough thread clearance to sew, place a empty bobbin in the case and thread the upper only. After placing bobbin in case, between holder and hook, Lightly hold your upper thread the same as pulling the bobbin thread up when preparing to sew. Gently run the machine by hand and observe the hook grab the thread as the needle goes down, and up again. Keep holding the thread and it will not bunch up under the machine, as there is no bobbin thread. The hook will just throw it off for the next cycle of the needle coming down. You dont want your thread getting pinched between the holder and the smooth of the bobbin case, so adjust the holder left or right accordingly.?

My no9 is loud, with the same bobbin assembly. The best way after adjusting it to avoid excessive noise is to oil your case. I have found that placing a small drop from the oil can in the case, then inserting and threading the bobbin is convenient and effective. W&W said to wipe with an oiled cloth originally. If you do it my way, its a good idea to wipe the case and bobbin off with a clean rag when done sewing or before changing loading a bobbin. Oiling your case either way is reccomended by W&W in the manual, which can be found in the files section. The early no9 manual gives directions for oiling the case and bobbin if the No8 manual does not.
