Cal-Hawk Parts

Recommended Posts

I have a Cal-Hawk 240-2020 Drill Press. During my last project he plastic handle which is used to raise and lower the table snapped off. I have been unable to find any sources for replacement parts for these (made in the late 90's).

And ideas?

Can you post a pic of the handle? It might make it easier to see it.

 

 

A picture would be helpful however couldn't you just make a handle with a piece of dowel, hex bolt, washers and a hex nut.

 

I will attach some pictures here...it appears to simply be connected to the metal shaft with some type of set screw. The key here is that the handle itself rotates as the handle is turned. Plus it needs to be strong enough to handle the leverage.

Just take it off and measure the shaft diameter maybe a pic of the shaft. My guess, one of us has a more current drill press with the same sized shaft. Grizzly, Powermatic or Jet probably has a model with the same shaft.

Bicycle pedal... Drill it for the set screw.

 

Why didn't I think of that! That is a great idea! Although it would be a bit bulky...

I will do that tonight and post the result, that is a good idea too!

 

Seems like you could jerry rig something to attach to the existing nub that's left.

I agree, I just don't know what, that wouldn't snap or wear out easily...

I see a set screw on the shaft so first take off the rest of the handle and measure up the shaft.  There will be handles available for that shaft size say at mcmaster carr.

Sorry for the dark pictures, I was in a hurry this morning...Hopefully I took the measurements right. Doesn't make much sense to me that the shaft is bigger than the inner diameter of the handle's sleeve...it's also worth noting that the shaft has two parallel flat spots, probably where the set screw grabs?

Tank you, I will check into those!

I don't see any metric handles for a round shaft.  You have a 12mm round shaft on that and that site seems mostly english not metric.

 

You could get a handle and drill the two holes you need yourself like one of the steel ones here

That would be what I would do, but I have access to the machine shop at work.  A small piece of aluminum would work as well say 1/2" pr 3/4" and with nice flat sides be easy to do.  Also adding a flat side for the to the shaft will let you have the set screw lock onto that and give you more torque with less worry of slippage than having the set screw on the shaft surface.  This might be an easier one to work with with wood working tools

This could also work  though again you would need to drill out the main bore and drill and tap a hole for the set screw.

And then you have things like this, that may or may not work

This might be just the thing, or not.

What you need is pretty easy to make out of readily aviable parts, but it can be a little more difficult making sure that something will work for you with no modification.

Thank you for all the links!

 

The one from Grainger looks pretty perfect, almost an exact match. Unfortunately they don't list the diameter of the shaft. It's only $12 though I mind as well just try it!

I checked my Powermatic and my neighbors jet both have 14mm shafts, so no luck there. Maybe call a grizzly retail location see if you can't find someone willing to check some of theirs on the sales floor.

Maybe look for a local store there are a few of them around here at least and see if they have one in stock so you could measure it.
