Has anyone experimented with taking the middle (removable) pulley lever out
and run their drill press with just one long belt? Obviously it would have
fewer speeds but I am wondering if there is a reason for the third pulley
besides adding speeds.
I just purchased some link belts and am thinking of doing it as one long
It's a pain in the butt to change speeds, so I haven't in ages. I do mostly
Opinions are appreciated.
How are you going to tension the belt properly without the idler pulley and
tensioner lever? It can be done. My benchtop DP had no idler pulley, but
instead an awkward, sliding motor mount.
However, if yours is a typical 12ish-speed drill press, you'll be looking at
a bit of an engineering challenge to figure out some new way to tension the
belt by moving the motor instead of the tensioner lever. It could
certainly be done somehow, but I submit that it would probably be far less
trouble just to use two belts and leave well enough alone.

I took the middle pulley out of my drill press about two years ago for the
very reason you mention. I put in one long link belt and everything has
been working fine, just a few less speeds. Changing speeds got a whole lot
easier and I do it more now than I did with all three pulleys. Tension is
not a problem since it is accomplished via a movable motor mount.
Thanks Woody. I think that is the direction I am heading. I have left my DP
at one speed for a couple of years now. Just too much of a hassle to change,
and for what really. Slow for metal, no need to be so slow for wood. Did you
get one of those keyless chucks for yours? If so, do you like it?
And Silvan, I appreciate your response and your time. I should have
mentioned that the DP I have has the motor mount which Woody writes of.
My thanks to both of you.
Don't have a keyless chuck on the drill press. Never found using a key all
that inconvenient to justify the cost of a new chuck. Biggest problem I
think people have is keeping track of the chuck key. I solved that by
drilling a hole on top of the pulley cover that I slip one leg of the key
into. Always know where the key is.
Ahhhhh...... yes! that is why I read the wreck. I've been thinking
about what a hassle it is to change speeds. It seems like I always
had the wrong belt on top.
Thank you all for posting. I will certainly try this out. Especially
as the change is reversible.
Next question- if I don't want to buy a link belt- what is an easy
way to figure out what length (single) belt I should get?
I'm using the big Delta, I think it is a 17-965.

You guys will love this.
After vowing to squeeze in a trip to Harbor Freight in the morning for
a link belt, I went out to the shop tonight to pull off the center
pulley and take some measurements just for S's & G's.
I took the belts off, than got out my (automotive) gear puller, as I
could not remove the motor pulley, of course it will have to be
flipped over. It came off okay with the puller. I turned my
attention to the center pulley. I applied the gear puller the same
way I had on the motor shaft. Nothing budged. I came in to the
computer, looked up the parts list (deltamachinery.com, nice having
that online). I couldn't see why the pulley would not lift off. I
went back, applied a little more pressure. Sure enough, cracked the
pulley. Damn. Just as the gear puller went flying, the whole center
pulley assembly lifted out from where it sits in the head casting.
shit. Nothing holding it there!
Okay- glad I can laugh at myself. And now I am committed to a 5 speed
drill press in place of a 16 speed. Guess I got what I wanted.

Well Mark, the pain in the butt starts with figuring out what speed I am
"supposed" to be using, and opening the top. Then its unloosening the motor
mount, figuring which pulley slots to use, shimming the belts to where they
should be and then retightening the motor mount. And all because someone
decided that a 5/64ths brad bit should go at a faster speed than a 3/8ths.
Yeuch. It is this kind of thing that makes ww'ing suck. More time is spent
preparing than doing, and I spend entirely too much time preparing and not
enough doing. I am learning tho.
Now I have the DP at a constant, fairly unagressive, speed. Haven't had a
problem since and it leads me to believe that in a 16 speed DP, 13 of the
speeds are really quite unnecessary.
In a nutshell, I want to woodwork from my gut more and my head less.
Opinion de moi only,
It will be easier to change one belt than two. Seems like nine times
out of 10, the wrong belt was on top, so I would end up taking both
belts all the way off the machine.
Also, the tension mechanism is clumsy, two screws, one on each side.
I am sure they could have found a better way to tighten the belt.
Might have cost more though.
Remember, I am using a 16.5 inch Delta. "YMMV"
