Step 1: Collecting Up Parts
Next remove the chuck and the clutch. There's a left hand thread set screw inside the chuck, then the chuck unscrews off the spindle.
For this project, all we need is the bushing, spindle, thrust bearing, set screw and the chuck. Toss the rest.
Step 2: Build a Base
Mark and center-punch your holes. Two to secure the block to the table and one to hold the bearing assembly.
Start with a pilot hole.
Then drill the pilot holes out to the size of your clamping bolts. In this case 3/8".
Install the bolts permanently into the block with nuts. Use fender washers and wing nuts to clamp it down to the drill press table from beneath.
Step 3: Align Block and Drill for Spindle.
Enlarge the hole progressively.
This bushing is 5/8" for 1/3 of its length then 11/16" for the rest. So we drill 5/8" all the way through, then 11/16" just deep enough to accomodate the wide part of the bushing plus the ball bearings and races. Be sure to measure yours as each drill may be different, even if you have two from the same manufacture.
Notice the stepped nature of the bushing.
Step 4: Install the Bushing
Next, drop the race (nothing more than a hardened steel washer) into the hole and fill it up with bearings.
Here it is complete. I cut a groove into the end of the spindle by spinning it in my drillpress while cutting with a hacksaw and installed a snap ring to hold it all together
Step 5: Try It Out!
Install another in the drillpress chuck and you're ready to roll...or turn. When you reduce the size of something or shape it in a lathe, that's called "Turning."
Mark the ends of your workpiece and countersink them slightly.
Install the workpiece in between the centers and make sure the reamers gouge the wood deeply so they grab instead of cutting tapers in the ends.
Make sure to spin the workpiece by hand before turning on the drillpress, then if everything looks good...let'er rip! There's no tool rest so you'll have to be satisfied with rasps and files, but it will work! Even on metal!
