POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

Bed going back on the stand.

Pretty straight forward getting everything lined up and in place.

Was on a roll so went ahead and put the headstock on also.

Should be able to get the saddle installed tomorrow. If my McMaster-Carr order shows up can get the door mounted for the motor side of the stand.

yea, no, this is the crystals. It's being affected by my right inner ear. Sucks that I can't clear this one. Not sure why. Went to the Dr today, and they tested me and confirmed it's BPV.

Remembered to go learn the difference. "BPPV and Meniere's: Two Usual Causes of Vertigo
Notably, both health complaints develop from a vestibular system defect. The only difference is one of them stems from dislodged calcium crystals while the other primarily develops due to excessive fluid buildup inside one of the inner ears."

I get awful ear aches from the fluid buildup. Funny how we can replace hearts, but haven't figured out the chemistry to target ear aches. Been on 125mg of Acetazolamide (no idea how to pronounce it, medical staff won't venture a guess either) for years now. No vertigo, but I can careen like a drunk Soldier back from a 12 hr pass. Worst part is bangs & bumps in the shop with minor momentos I have no idea where they came from

I went at an old blade for a splitter and mount for a blade guard with a cut off disc

Interesting. Did the piece stay flat once you removed it from the rest of the blade?

I was wondering if there would be tensions that might cause it to warp in weird ways once it was cut. I know really big mill blades are not “flat” at zero rpm’s, they need the spinning of the arbour to flatten them out. Obviously this is smaller, but I still wondered about it.
 
Re-did some of the previous guys work on the notcher. The cutter spindle had excessive runout. To fix it, I turned a 1.250” mandrel with a flat, slid the cutter holder onto it, tightened the set screws onto the flat, center drilled the end of the spindle, and turned the spindle down from 1.000” to .875” using a live center in the tailstock. I made a .875” ID x 1.25” OD sleeve and pressed it onto the spindle with green cylindrical loctite for good measure. Apparently, 0.0005-0.001” press fit was a little bit too much as my 20 ton press stalled out and I had to break out the propane torch to heat the sleeve to expand it enough to get it pressed all the way on. After it cooled down some, it went back on the lathe and I turned the sleeve down to 1.000” using the mandrel and live center again. Then, over to the mill to cut a new 1/4” keyway 180 degrees from the old one for the LoveJoy coupler.

I noticed that the shaft through the gearbox didn’t have a keyway for the LoveJoy coupler, only flats ground for the set screws. When I removed the shaft from the gearbox, I found what appeared to be a keyway that was hand cut with a die grinder. It’s uglier in person than what the picture shows. I made a new shaft with 3/16” keyways for the gearbox and coupler and a sleeve to fit between them to keep the shaft from sliding in the gearbox and to keep the coupler halves engaged.

Wired the motor and made a few test cuts. At first, it was a little sketchy as the vise was jumping around quite a bit. I tightened the gib screws on the mill table unit and it improved a lot.

Sure, something more to learn. I didn't throw it on the surface plate, but on the saw table, that surprisingly is pretty flat, it doesn't rock. So probably good enough for the task. After using the disc cutter, I suspect the hardness is less toward the center of the blade. FWIW it measured out @ ~ .060"
 
Rotary switch, QCGB, and quadrant gears installed today.

Need to pickup a retainer for the power cord to finish the wiring, then get the door mounted.
Manually spinning via the large quadrant gear it seems a little stiff but spins smoothly.
