Pure silicone on the quadrant??

Post by godavid2 »

Nick, in one of his videos on Maintenance of the headstock uses pure silicone on the quadrant. Pure silicone to my understanding is used to keep rubber seals soft. So I'm kind of confused about using pure silicone on the steel parts of quadrant. I hope someone can enlighten me on this reasoning. Thanks for the help in advance. The forums are an invaluable resource when it comes to working on the Shopsmith.

Personally, I would not like any silicon in my 'shop' since it drives finishes nuts. I know it is used inside, but it has to outside at some point.

Silicone is slippery, but I agree that it should be kept away from the finishing process.

So why would it be used on the quadrant? Because it is slippery? As a lubricant? The pure stuff has no petroleum products in it.

I have used silicone on the table quadrants. It works for a while, but the slippery benefit disappears in a few days. I've never had a problem with contamination of any wood finishes.

Shopsmith recommends graphite for lube of the quadrants. I've had better luck with silicone than graphite. Easier and less messy.

I probably would never need lubrication of the quadrants if they were perfectly adjusted, but the lube is a whole lot easier - less time consuming and frustrating - than re-alignment for a slight rub when rotating the table to drill press configuration.

I haven't seen the source you mentioned but I know I don't do it that way. I also followed some un-named source and tried to use bee's wax. That worked OK in the summer but when I tried to use my machine when the temperature was like 50 degrees nothing would move. Ended up chipping the wax off to get thing moving.

I went back to the stick grease I've always used. I went from 1976 until last year without having any issues on one of my machine... then I upgraded to a powerpro. The gears still have years on them. In fact I'm going to use them to repair one of my other machines.

Big thing is to keep things cleaned and lubed. Saw dust is not your friend and when it combines with things you get crud, that is even less of a friend.
