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

[wachuko]

Hate those crank sensors... I damaged a set once when I did not gap them correctly... Flywheel took them out. This was on a 1987 car... I forgot to install the spacer that provided the correct gap. And of course, reaching the place where they need to be installed was a royal pain in the a...

 

[Just for fun]

Yesterday I had a little fun in the machine shop. Installing the DRO on the lathe, I needed to drill two 5 mm holes close to the ways. I tried three different drills and they all hit the ways and wouldn't let me drill the holes straight. The die grinder lined up perfect but would only except a 1/4" shank. A little work on the lathe to make a 5 mm collet and the problem was solved.



I cut the slot with a hack saw!

Some time back I bought one of those collet block chuck kits for a specific project, and I've been pleasantly surprised by how regularly I use it. It has occupied a space in one of my tool drawers which has been a little frustrating for a couple of reasons. First, it came in a nice little wooden box with a hinged lid, but that actually made it a little cumbersome to use because of where it needed to be placed in the drawer. And secondly, the box had a relatively large footprint - about 6"x6" - which was part of the reason for its specific placement in the tool drawer. I decided to make a rack that would hold the parts vertically instead of horizontally. That resulted in a smaller footprint of 4-1/4"x4-1/4". And the parts slip off without needing to move anything around. A very easy project and, except for the 1/4-20 bolts, every part was made from scrap aluminum. Below are some pictures.

I like the way you organized them.

Thanks, Tom. I actually drew it to scale on some quadrille paper and placed the pieces on the drawing before I started milling anything. Pretty much knew exactly what I would get in advance.

I got bored the other day and it’s been so stinking cold (for April anyway) that I started working on another machine. It’s a 223 zig-zag / blind stitch and I think the first of the Singers made at the Utsonomiya factory in Japan. It’s in super shape for its age (1960) and by the looks of it was never really used. Super clean too, well, except for this….



Think you put enough grease in there, guys? There’s a couple of bevel gears in there somewhere that transmit power to the shuttle but you can’t see them for all the dried goo. Man, it was so old it wasn’t even sticky anymore, just crumbly! A couple of hours later and…



Clean. I put some (some, not half a tube) of new Tri Flow clear grease on the teeth and buttoned it up again. Good for another few years. Thanks for looking.

Yep Francist. I’m going to use your dried grease as my segue.
I purchased another Rohm Scroll / Independent chuck off of EBay.
This one is a 4-jaw scroll with independent jaws .
Anyway the damned thing was frozen solid due to dried up grease stuck to everything. Took me a few hours to get it disassembled and then soak it in degreaser.
Weather was nice so didn’t have to use my “clean room”

(if only I had a clean room)

I don't understand. You have a scroll.. which to my thinking means that it controls all the jaws, but you say it's independent... How does that work exactly?

edit: I get it. I just looked at the jaws. You have both independent to adjust , but it opens all at once.
Nice.. I didn't know that existed.

Finished up my part of my daughter's terrarium project. She was super happy and I'm super happy I've got some space back in my garage

Made a new elevating screw for my golf ball mortar, this one has left hand threads so turning the knob clockwise elevates the gun. I also had to make a 3/8-24 left hand pin nut.
