We paid $7.00 for our 4622A at a yard sale. It needed one part that cost about $10.00. Then it needed lubed and now it does excellent stretch stitches. No external cams, just internal ones and it's simple to use. That is the only reason it's still here and hasn't been rehomed.
Have you removed all the little knobs at the top of the front if they pass through the top piece?
Yeah I pulled the little knobs off. Something is hung up by the right side handle somewhere. I'll have to look it over next time I get to the shop. I'll have to deal with the accident stuff tomorrow and work a couple hours.
Well, I had a thorough look at my Necchi Supernova Automatica machine last night and it's the first machine I've ever owned that was as dirty as a barbecue! The other machines I've come to own have seemed more clean and dry, even if they are dirty in areas and have packed in lint etc. This one is like a grease pit!! All the lint and dirt is stuck on with this brown grease.
Anyway, I set to work in grease removal as I figured that would be the only way to remove all the unwanted dirt. It also looks like it's all built up around the moving parts so I suppose it won't work as smoothly unless it gets removed and replaced with fresh oil.
My question is... How far should I take it? I've noticed some people talk about sitting their mechanical machines in a bucket of soapy water (and now I know why!!) but this machine has electrics underneath. Am I attempting to get all the parts back to 'shiny and new' or just 'serviceable'? ....and what should I be using to remove it?
I hope someone out there will be patient enough to explain this stuff to me. I am SO desperate to learn how to do all of this myself, but every time I look at a new machine there are always new issues and new questions. Also the mechanics are a lot more complicated than for a simple SS machine. There is a nifty button that you're supposed to be able to turn and push down to drop the feed dogs. It's a spring loaded mechanism that is so sluggish it does absolutely nothing, plus the area around the feed dogs is all black and gunged up anyway, so it's hard to know what end the problem might be at. If I could get THAT working again, I would be as pleased as punch :D
Then I cleaned up on a White zz - it was sort of dirty but not too bad. It actually didn't get the cleaning the 15 got. I sort of wondered if I needed to get that aggressive with the White or not. I decided not. It sews just fine. It looks fine. It could have some of the exterior oil off the moving parts but why. I think some of that oil is protective anyway.
Then I checked on my Singer 319 which has set for way too long. It was fairly thoroughly cleaned a while back. It was gummed up when I checked it. I'm pretty sure I used Tri-flo on it... but then again maybe not. I don't really remember. Maybe it was from before I discovered the joys of T-F? Maybe something needed some more cleaning. That machine was horrible. Here is a link: http://www.quiltingboard.com/picture...c-t162425.html Another thing on my never ending to do list. I would also go about cleaning it different these days... sigh. always learning.
On sewing machines I ONLY use Tri-Flow as a lubricant.
As to bolt freeing, I start with Kroil (NOT an lubricant, it is WD-40 on steroids without the residue) It is actually referred to in its litrature as "the oil that creeps" If that does not work I spray some PB-Blaster into a cup and then apply it with q-tips. This is available at most auto parts stores. I learned about it when I owned two 1966 barracuda's... old rusty outdoor bolts.... The last level is a heat gun (hair dryer is better) I have not had that fail yet.
Where do you buy Kroil?
Tri_Flow is a lubricant. it has a silicon base so even when it dries it leaves behind a lubricant (dry silicon)
Kroil is a penetrating oil. it's function is to seep into cracks and crevasses and soften any existing rust and/or contaminants. It is almost anti oil.
This stuff REALLY has a amazingly low surface tension... Take two flat plates of material. Put on one drop of other stuff (Tri-Flow, WD-40, sewing machine oil, etc) and on the other put one drop of Kroil. In a few hours you will see the Kroil one has spread out WAY more than any of the others. I buy mine from McMaster Carr http://www.mcmaster.com/
hey :) At the rate I've acquired treadles I'm thinking it will make more sense to just buy a whole spool of leather for belts. Does anyone have a recommendation of a place I can buy it and the staples used for them? I could use 4 or 5 belts right now as it is.
