I have four vintage machines, 3 Singers and a Kenmore. From all my reading of this Forum, I have gathered that Tri-Flow Lubricant is the lubricant of choice for these machines. Is this the product to use in place of Singer All Purpose Machine Oil? And what about greasing the gears? What do I use in place of Singer lubricant? Tri-Flow Synthetic Grease?
The last time I lubricated my 401A, I did something wrong because it siezed up. With the use of a penetrating agent, I have been able to get everything free and working in proper order. I lubricated my 403A at the same time and did not have any problem. I don't know what went wrong. It is now time to lubricate the 401A (because I had to remove all the lubricant), by 403A (due to use), and my 301A (due to use). How do I avoid the the seizing problem?
Any suggestions would be greatly appreciated
