Drill press table crank fix
#11
While this happened to a mid-90s Craftsman drill press, I believe that some other brands use the same crank handle that broke. Perhaps this will be useful.

I had some work in a big, heavy vice that was sitting on the drill press table, and when I went to lift the table, the crank handle broke off in my hand. I couldn't believe that the handle was made of mostly plastic. From appearances, I thought it was a die cast metal of some sort, but I was wrong.

Looking around on the internet, this looked to be a common problem for a couple of different presses. Replacement cranks were plastic too -  no thanks!

I considered other solutions and settled on an aluminum wheel crank from industrial supplier McMaster-Carr. The wheel had a smaller mounting hole than the shaft, but I could drill that out to fit. I also needed to drill and tap a side hole for a 1/4-28 set-screw to hold it onto a flat milled on the table lift shaft. The wheel itself was gorgeously made.

I created some soft jaws for my vice to hold the wheel without marring it. I drilled the through-hole larger to fit the 9/16" diameter drill-press shaft, then cross-drilled and tapped 1/4-28  threads for the set screw.

It works like a charm, and looks better too!

THAT'S not going to break off in my hand!

BTW, a replacement plastic crank was $30 online, but this metal wheel with crank was $50. It's well worth the extra money for the peace of mind.

My drill press came with a broken cast iron crank. I bought a plastic one for $15 or something like that. Been going for years. My only complaint is sometimes I have to lift the table as I'm cranking.

That wheel looks nice. With the drill press table I'd like to build, it would work nicely, with some modification. As-is, it looks proud of the table top? Many many times I have to position long workpieces over the handle area and with a proud handle I don't know if it would work. But if it works it works.

I'm sure this will be replicated many times. Thank ypu
I no longer build museums but don't want to change my name. My new job is a lot less stressful. Life is much better.

My Delta DP has a similar OEM crank, I'd like to do that just as an upgrade. Got a part number from Mcmaster?
I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.
