So I got the bright idea that it would be nice to extend the power collet and add some threads on the back so I could also print a nut to attach it with.
That worked out well:
My first attempts used M25x1.5 threads. But I couldn’t get them to work on FDM or SLA. I added chamfers but it still didn’t help. Added some offset on the threads to loosen the clearance … .still no luck.
Finally I gave up and used M25x2 threads and both the FDM and SLA versions worked. Though I may not have left quite enough threads for it to snug up without a gasket.
The SLA version is a bit nicer (you can see it near the back) the FDM version the nut doesn’t quite thread all the way because two paths didn’t quite sick right as it was printing. (It’s the one iwht the LED’s in the near the bottom)
Honestly anything I printed today would work. But…I want it to be what I want and not just “good enough”.
While these were printing I made my less than traditional thanksgiving dinner. Since it’s just me and my Daughter and she is the pickiest of picky eaters there’s little point in making a turkey. I did last year (even though I was so sick I could barely get off the couch) and it basically went to waste. So I figured since I’m working from home and can monitor something over a long slow cook why not try the sous vide recipe I’ve been wanting to try since I got a circulator a few years ago. 72 hour ribs:
As their name implies I started them on Monday. Insanely easy recipe. Just seal beef short ribs in vacuum bags and sous vide at 140f for 72 hours. I did slightly salt them first. The result was pretty impressive:
Even without any sauce or additional seasoning they were incredible. I did make a red wine reduction to go over them…but it was totally unnecessary.
I also made some roasted potatoes (no photo, nothing fancy) as well as a brussels sprout cranberry salad and an apple pie:
So it was fairly easy to bounce between 1-2 hour prints ( FDM prints raged from 15 minutes for just a nut to 1:120 SLA were all 2 hours.) and cooking.
I just have to make an appropriate hole in the case now. My spade bit is mysteriously missing the 1" bit (I think I may have destroyed it drilling holes in a stump a few years back) and my hole saw set…is…not usable. Apparently water got into it - which is a bit of a feat since I live in the desert. But two years ago we had the remnants of a hurricane blow through and it took the tarp off my outside kitchen - which the bits were stored in. Haven’t had to use them since then…so I was a bit surprised to find more rust than bits. I should have another 1" bit around here somewhere though. I’d really rather not have to go to a hardware store right now.
And I may print the collet in SLA in some nicer resin. This resin is one of the toughest I have…but it’s just not very attractive. Or…maybe I’ll just give it a quick sanding and a coat of paint.
Going to sleep on it. But I’m really itching to get this case together. Tonight I was in the mood to play the synth…but…it’s just too torn apart. I need to get things that work and I’m happy with moved into this case and get 2 more power supplies running. Thankfully it’s a long weekend ahead so I should make good progress. And I have enough left overs I won’t have to cool for a few days 
But…I also need to finish a few fixes on the sandrail now that the weather is nice out:
Note to self…set the jack stands further back than the rear axle in the future
The wiring on there is something I’m definitely not proud of…and…frankly am kind of amazed myself that it works at all:
(photos are actually from last year when I coaxed it out of a 12 year slumber.)
There’s a coolant line that’s leaking I need to replace, but I also need to add a splitter on it to add a new sensor for the cooling fan. So it’s not a straight forward replacement and I’ve been putting it off since it was just sketchy looking and not actually leaking. But it started leaking after nursing the rail back to life so I need to finally do it right.
And one of these days if I move to a house with a garage again I’ll tear it down to the bare frame for the 4rd time and do it right again. (the first time I had no clue what i was doing. The second time I did it right and it was gorgeous when I was done but the motor was never reliable. The third time I switched motors and decided I wanted the motor to prove itself before I put the effort into repainting again…even though I had already stripped and primed the frame. And the darn thing worked so well and so reliable that I just ran it for a few years…and then took 13 years of due to a combination of reasons but mostly lack of a garage. But I put the time in in the driveway last year to get it running again and took my daughter out…and she didn’t hate it. But we didn’t get to drive much because the line started leaking.
Ok - sorry for the diversions. Once I get power back on these racks this weekend it will be easier to focus on synths again
