Hypomelanistic Report post Posted June 28, 2022 Hello all, Last year I bought a pretty ratty looking Singer 211U166A from a local auction. Throughout my tinkering I have found a lot of interesting information on this forum. I am far from finished with the work on my machine, but I figured it would be worth starting a build/progress thread. Hopefully someone finds these pictures to be helpful on a project of their own. So far I've redone the black oxide on a lot of the rusted screws, added a machine mounted small (but still 0.44hp) servo motor that is designed for a CNC machine tool, and replaced about half of the oiling felt. If anyone has any questions or suggestions I would like to hear them. I am new to the sewing world so I dont really know what I'm doing. Quote Share this post Link to post Share on other sites

trash treasure Report post Posted June 28, 2022 Did you do the machine work on the handwheel? If so - Very nice work. Quote Share this post Link to post Share on other sites
dikman Report post Posted June 28, 2022 Some nice work there. If it was me, though, I would have made the handwheel bigger as it will help give better control and torque. How do you intend controlling the servo? Quote Share this post Link to post Share on other sites

I am thinking I will anodize it black to match the rest of the machine. 15 hours ago, Handstitched said: Seeing the machine collapsed inside the table is a sad sight to see.

I ended up at 5" diameter. I forget the size of the original but the new one is a little bigger. I made a pedal with a rotary encoder that talks to the motor. I dont have an actual picture of the pedal right now but this a screenshot of the model. Quote Share this post Link to post Share on other sites

dikman Report post Posted June 29, 2022 Good question. The common way that most of the restorers on youtube do it is to either heat them and drop them in oil or use the gunblue stuff that is used for cold-blueing on firearms. I'm interested if there's another way. Quote Share this post Link to post Share on other sites
trash treasure Report post Posted June 29, 2022 The handwheel looks to be aluminum - I think he said he might anodize the parts, which is an electrolytic process used for aluminum. You can use dye in the process, and create many colors, that way. Quote Share this post Link to post Share on other sites

I'm interested if there's another way. I used EPI ultra black 400 and their E-Tec 512 rust preventative. This requires you to boil the parts in the solution at about 290 degrees Fahrenheit. My understanding is this is a more industrial product than cold bluing. I have never been able to get something that looks factory with cold bluing stuff I’ve tried so I went this route.

Electrolysis on the rusty parts? glenn I used Rustoleum “Rust Dissolver” on the rusty parts which removed the rust but still leaves the pitted surface. So after that I hit them with some sand paper and scotch brite so they would have a smooth finish under the black oxide. Quote Share this post Link to post Share on other sites

dikman Report post Posted June 30, 2022 Thanks mate, a bit like Parkerising then, except it's black rather than the gunmetal colour I got. As I expected, it doesn't appear to be available here. No surprise there. Quote Share this post Link to post Share on other sites
arjon Report post Posted July 2, 2022 This is amazing. I have the same machine, it's nice to see someone else with one. Looking forward to seeing more contributions from you. Very nice work. Quote Share this post Link to post Share on other sites
Hypomelanistic Report post Posted July 3, 2022 Hi Arjon thats awesome I am glad you enjoyed the pictures. I have a question for you (or anyone else who might also have a similar machine). Do you happen to know where the "Feed Driving Eccentric Connection Oil Tube" hooks up on the bottom of the machine? Mine was falling apart when I got it so I am not sure. The "Feed Driving Eccentric Connection" (i circled in blue) of course moves depending on the stitch length. That makes me think if i hook the felt to it (there is a hole on the top of it that maybe the end of the felt could be stuffed into) it might eventually break because of the movement. Any insights? Thanks a ton for the help. Quote Share this post Link to post Share on other sites
Handstitched Report post Posted July 4, 2022 @Hypomelanistic Can't help you with the oil tubes unfortunately , thats totally foreign to me. Are you going to restore the old table, or get a new one? HS Quote Share this post Link to post Share on other sites
Hypomelanistic Report post Posted July 5, 2022 @Handstitched I don't have a plan for the table yet but I think the original is too far gone. Quote Share this post Link to post Share on other sites
