I am thinking about buying Delta DP 350 Drill Press.
Here is my concern:
according to the manual, the Delta variable transmission requires weekly lubrication.
Is it mandatory when you don't use it too often.
What would happen if machine sits idle for 6 month with no weekly oiling?
I'd think twice before buying one of those. The industrial variable speed setup
didn't translate well into a bottom-rung drill press, and it doesn't give you a
wider speed range than the normal belt drive. Unless you really need an
infinite range, skip it.
Excellent DP. I have had it for 1-year and no problems. I also use it with
the mortise attachment for mortises.
"The industrial variable speed setup didn't translate well into a

"and it doesn't give you a wider speed range than the normal belt drive."
DP350 ranges from 500 to 3100 rpm. When would you have an application that
would require a speed outside of this range?
Putting a complicated system like that on a machine that needs to be low priced
was a stretch. You might love yours, but I've heard of nothing but trouble with
these things. Maybe they've improved it.
For a production shop that actually needs a variable speed drill press, they
work out really well on the $800 models that are a good, time-tested design.
500 RPM is a very high low speed. Usually folks outgrow that pretty soon.
That's why there's a big interest in jackshaft modifications for older DPs
without a low speed range. Too high for a lot of metal work and some larger
wood bits or hole saws. Good drill presses go down to somewhere in the 100-200
range. If you're going to spend $200 on a drill press, I'd rather have a bigger
machine with a usable speed range instead of a benchtop with a variable speed
