When I started using the new machine, it was Ok, but was noisy and strained a bit to get going. In addition it would not hold a stitch length. This last problem may have been just a loose screw, but it also could have been due to friction in the drive train. The rust was worse than I thought, most of the chassis of the machine was showing signs of rust under the black Japanning. I have therefore spent the last few weeks stripping every single part off the machine, including the vertical shafts that drive the hook and drive dogs, and the main shaft that drives the needle and top tensioning. Not a lot on the web on about taking the main shaft out of a 99, and no, it’s not the same as a 66. It’s not as hard as it looks, it just takes a bit of bravery, and some knowledge of the engineering of the day.
\nI then scraped all the Japanning off the chassis, some of which came off with the rust, some needed a bit more persuading. Once clean, I gave it a couple of coats of a heavy duty primer, and applied some black enamel, flatted it down, and applied some more, and repeated it again!
\nAfter waiting a week or so for the enamel to cure, I started reassembly, cleaning every single piece with a rotary tool (think Dremel) using wire brushes and hard felt pads and a cleaning compound.This made reassembly a bit of a chore, but after the big job of re-inserting the two main shafts, the rest is reasonably straightforward. Finally, adjustments were made to the drive dog fore and aft, side to side and vertical position,and to the needle bar height and the needle to hook timing, and also to the presser foot, upper and lower tension.
\nMost of these adjustments were made twice, as something slipped after a few minutes use, and the easiest way was to start again.
\nNext job is to clean up after all the work, and polish the paintwork to a better shine, and the make some nice simple decals for it. In the mean time I will put some photos up here.<\/p>\n
