After my teardown experience with the Smith Corona 120 Electric we talked about and watching videos like this, I can see how they all have a mechanical relationship within the family, similarities among them all. In case you missed it in another video, update on my 120 Electric is the motor is so tight very hard to move with a towel and needle nose pliers on the shaft. Bad bearings? The belts looked good but have the classic kink and feel like rawhide dog bones. It must have been used maybe 5 years and I bet the carriage draw string is what snapped and it was put away for nearly 45 years and sat in it's Samsonite case waiting. Then as the belts became it's breaks, someone found it pluged it in and turned it on and it burned up the motor as the belts just held it it place as they were when I looked at it...that free spinging pully isnt there or its frozen to the shaft, but it's not working. I took the belts off, and turned it on and nothing. I tried to clean it and lube it on a tip of a tooth pick and manually turn it. And still nothing. I went ahead and cleaned everything up and it sure is pretty, cleaned right up for church as they use to say, with manipulation of the drive wheel all the keys work. The draw spring feels fine, a green plastic case is on it, and its string too has snapped as I mentioned. I'm tempted to fix it, find a motor which through heave study I found that Kodak used the same motors in their 600-650-700 series carousel slide projectors in the 70's, 80's and early 90's. So they are out there. It had a regulator in it to make it move then stop based on the input of the handheld switch. Wow what a motor they stuck in those huh..lol! But yeah, get a motor, two O-rings, and fix the carriage draw string and see what we got...or just return it.... Having seen how that motor is in there, I understand what you mean now. And that is really the main reason, I'll probably just return it and look for another one I can Buy, could keep it for spare parts...thats another thought I had....be interested in your thoughts on this, overall? I may contact you again Sir, but for a different question, I have your number, and I hope you are having a Great Day! Always a thumbs up from me and a thank you for the video!
You can tie a piece if fishing line on the end of the new draw band and lead the fishing line through the hole and use it to pull the new line through. Just have to tie it tight and a small knot but makes it easier.
If you need more tension from the mainspring because it’s gotten weak, would you turn it a few extra times before connecting the drawband to the carriage?
Yes, I would say on average if a main spring has a maximum of 10 turns, the factory probably turns it 7 leaving 3 more potentially. Probably not a good idea to turn all the way to max, as these can get more brittle with age and might not be able to handle the max stress.
Thank you very much. I managed to fix the same problem on my Olivetti studio 46 by watching your video.
Thanks ! I always remember on Royals the Rod pulls out to the Right! Triple R's like a pirate rrr
Fun little machines 👍
