Re: High frequency vibration on Y axis

These

- With or without the endmill cutting, so even when just cranking the handle.
- Only during a specific operation using a 3/16" endmill to cut a slot.

Re: Uneven cut

Check all the gibs. A loose one can do that because of the cyclic force you apply to the table as you crank.

Did you have the x axis locked?

Re: OP even for the Junk Drawer - Corona virus

This is true, but it is not necessary that everyone be infected. As the fraction of the population that has had the disease and is now immune increases it becomes harder and harder for the disease to spread. This is because members of the set of vulnerable individuals become less and less likely to ...

Weld those eyebolts closed, don't lift overhead, and you'll be fine.

I've been in a JD shop where the repair team [yes, team] was gathered around a laptop connected to the tractor. Nuts. But everyone says...

The gib is not the only point of contact and in any case the bed always wears.

Re: LED Shop Lighting

I assume the Kwh rates will climb to cover the reduction of Kwh used by LED fixtures. Since the actual cost of the power is negligible, we are primarily paying for the labor and parts maintenance of the grid. I would think unless you cut the lineman's wages, the per Kwh price will have to go up. If...
