Made a conversation piece for my brothers' birthday. I didn't have the right size drill bit for the brass nut I'm making for it 9/16x18. The drill bit should be here tomorrow then I will replace the commercial nut with the brass nut. Looks a lot better than the first one I made when I first got my lathe.
I probably made a mistake my drilling it out to 1/2", drilling brass is a little touchy.

Started printing out a couple gears for my atlas 10f:
Going to give them a try and see if it calms down some of the ring, clash and rattle noises.
Thats the combo gear off the spindle gear that drives the change gears and the transfer gear in the reversing gearbox. Both of those gears are quite noisy, as when I disconnect them the lathe quiets right down.
I’m kind of hoping the abs gears will absorb some of the clashing/ringing in the gear train and quiet the whole machine down.
These are a first kick at the cat, mostly a “proof of concept”. If it works, I’ll redesign them to incorporate a bronze bushing to run on the pins/bolts/axles they run on.

A while back, I bought these two old card files...
Today I discovered that they are a PERFECT fit on top of a Kennedy tool box...
It's like they were designed to fit between the top flange of a Kennedy box...
So I began sorting all of my horizontal mill cutters and slitting saws and filling the drawers on the card files...
...putting 4x6 index cards between them with the sizes listed.

Well, proof of concept successful!
Cleaned it up, reamed the bore to size and popped it into the gear train.
Pretty much all the gear “ring” is gone!
I won’t call it quiet, but the noise level is so low I almost feel guilty calling it noise.
It’s such a good fit, I’m just going to run it to failure to see where the failure happens. I suspect it will be in the pin bore where it sees the most friction/heat. I did run it up to 1200 rpm and no abs melting or other issues were apparent. Glass temp for abs (ie: temp where it starts to go soft and pliable) is right around 100-110 C and I don’t think it will ever get that hot. There were a few abs “shavings”, but thats likely just the abs gear bedding in/mating with the zamak gears.
Next up: reversing gearbox.
