With the old singers there are belt drive and gear drive. I got the belt drive because thats what I found and I have a commercial walking foot. The only limitation I have had so far with the singer is smaller thread size. I dont try to go thru several thick layers, that's what my other machine...
In that auto restoration world they have a chrome paint. Not the fake rattlecan stuff but a real 4 or 5 layer process but I bet it aint cheap. Can do black or red chrome colors too
I have 2 "sensors" the higher one is a regular float. The lower one is an actual electrical sensor that is made from a piece of 1/2 copper pipe, 12guage copper wire and a transistor with some other misc electronics and a relay. No float to get stuck up and never had pump stuck on because of debris
Here is something kinda on/off target...
We had a Rollercoaster at one of the places I worked at and depending on the temp out we would go from 10wt to 40wt. And in mid summer we would switch to grease. It was all about adjusting speed. Oil did make an awful mess. I have no experience with boat...
Yes. All new shafts, bearings etc.... just about everything. Would work until I torqued cap. If it was slightly loose it would operate. Removed 1 of 2 shims and been good ever since. 3 maybe 4 seasons so far with 1 water pump change so far
