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

The beginning of a turn table project:

Picked up inexpensively because it has mechanical and cosmetic issues. But it was a really good price because of that. This is completely analog, so it's more like working on a clock than something electronic. Nothing to solder other than the power and RCA cables. The only electrical component on it is literally just the motor. German made in a factory near the black forest, so that it's more like a mechanical clock underneath kinda makes sense. Germans tend to engineer good stuff and this doesn't seem to buck that trend.

Plan is to tear it down, clean, lubricate and adjust, build a new wooden plinth for it and then enjoy!

I started work again on my countershaft pulley. I got the math wrong with the original and the belt length wasn't the same on all three ratios.

Turned off the grooves for the two largest sheaves (leaving a bit behind for JB weld). Then ground a trepanning bit to cut the core out of a 4" round of alu. Cut off the extra length, then faced and bored to dimension. It's currently being JB welded :)

Those were good turntables. Seemed like every other person I new back in the early 70's had one. I have a Pioneer PL 350 that has a tone arm positioning issue that I need to fix. Not sure if its mechanical, or electronic in nature (probably mechanical), but it probably won't take long to find out once I open it up. Mike

I am impressed with being able to trepanning to that depth. I would have broke the tool bit way before. Good job!

Thanks, though I've broken allot of trepanning bits myself :) I've found that the deeper you go, the thicker the bit has to be - this one is around 0.14" wide at the tip and ~7/8" long. Thankfully my SB wide 9 can handle it, in alu at least.

Sounds like audio interest is gaining once again . Maybe I'll fire up the Carver system soon . :encourage:

Now that you are retired, audio makes a good hobby—fun, multidimensional, not too expensive, and time-consuming.

My system comes from right at the end of the “stereo” era, before “home theater” dominated the discussion. I have an old Carver commercial amp, but not in the main system. That system does, however, include a Carver TX-11a tuner—one of the best analog tuners of my experience.

For me, CD-player sustainability has been the major challenge. I still listen to CDs and LPs because owning those is an unassailable lifetime license to listening to them, no matter how much Disney gets Congress to extend copyrights. But the players were not built to last the ages.

Just as with most things, sustaining hobbies that use old apparatus requires repair skills. But that’s part of the hobby.

A Thorens TD-166 for me, from about 1979. Easy to restore. I almost acquired an old Systemdek that would have given me some lathe practice, but the deal fell through.
