New Post Drill Chuck

Post Drill Chuck EnhancementI gave up on trying to make modern bits work in my post drill and just installed a modern Jacobs chuck. The issue was finding a 1/2″ straight shank for the chuck rather than the typical morse tapers out there now. I guess it wasn’t really an issue seeing as I found it on Amazon and ordered. But I had to wait like 3 days!!!

So I threaded the shank into the chuck and it slid into the existing post drill chuck with a nice piston fit. This is tightened down with a set screw and I was off to the races. No wobble or deviation any longer and I’m happy to welcome a new member to my shop.

Hey, Shannon, you found a flywheel! Congrats.

MAN! What I wouldn’t do for a good user of a post drill… except pay $150+ for a rusted solid, rehab nightmare on Ebay.

Guess what? Since my last post I actually did find a good user on Craig’s List. I had to drive halfway across Colorado (Boulder to Salida and back) to get it, and it needs some tweaks- like… a new chuck for instance! Thanks for posting this and other info on the post drill. No doubt it’ll help me breath new life into mine. I don’t suppose you would divulge the exact names and sources of the chuck and related parts (kind of like Bob Easton did with his treadle lathe parts)? This is the first drill press I’ve owned so I’m a bit helpless in regards to chucks and parts. Thanks!

Hi Shannon,
I have a bead on a post drill that seems to be in good shape. It all seems to work. rather than having a small gear with the lever arm on like the one you have. This one has a large diameter gear with the the handle right on the gear. I suppose this also eliminates the need for a flywheel, this one also has a modern chuck on it already. Looking on E-bay it seems like this would go for between 150 and 200. Does that seem reasonable to you? Also now that you have a couple of years behind your post drill what do you think? I do not have a drill press nor have I ever owned one, though I have used them in the past. Do you find that everything you can do with a drill press you can do with the post drill? I am thinking something like cutting plugs or using a step drill might be too much for the one arm horse power.

Thanks for your time.

    I can’t really picture the drill you are talking about so pricing is a mystery for me in this case. I think 150-200 for the type of post drill I have is acceptable if that helps. Just make sure all the parts are there and it is in working order.
    I love my post drill and it does everything my old benchtop drill press would do. It really depends on what you want this for as to whether it will meet your needs. I admit I don’t do a lot of work that needs a drill press so it isn’t hard to satisfy me. But for example I used it last night to prepare pen blanks for the lathe just like I used to use my drill press and there was no issue with the post drill doing the same task. In your case with the tasks you mention I know my post drill wouldn’t flinch at all. The flywheel does all the work.

Shannon:

Another site recommends cutting the new arbor to size (to reduce wobble, I assume) and milling a flat on it to accept the set screw. Did you do either? I have a post drill and am trying to adapt it to accept modern bits. I know next to nothing about drills, chucks or arbors.

Thanks for any help!

    I just added a modern chuck with an untapered shank that matched the existing recess. I had to buy the chuck and the shank separately but it was a simple install and now the drill runs true as can be and I can use any bit I want.
