What Did You Buy Today?

That sounds like a good reason there. Channeling is a problem with filters because it robs efficiency in terms of capacity. If you overbuild it enough, you should be clearing the pass-thru as dry as it's going to be, channels or not. Since silica beads are smooth, there is no need to settle or tamp them like you would with carbon powder or other media that is compressible and has great issues with caking and channeling. They are light enough to blow, so I think gravity working opposite is a sound plan.

That will work. Don't plumb it like he shows though, you want the air to enter at the top and exit at the bottom. The air should pass through the beads without disturbing them for the best results!

I use the orange/green beads, I read the pink/blue give off cobalt dust or something like that. I sure Pontiac John can comment if it's an issue. You can absolutely dry them low and slow in the oven.

You are correct, sir! Orange/green is safe, blue has cobalt. We were getting cobalt hits from desiccated samples at the Army analytical lab from using them in a cabinet with blue beads (no stirring or mixing, just convection). That's never something you want to find out after certificates have been signed, certified, and issued. Besides, the only cobalt that I want to handle is metallic. Organometallics and salts are scary.

Wachuko's water filter canister has a siphon tube in it, what difference does it make which direction the air flows?

With a high volume of air the beads could levitate or boil allowing the air to bypass them, sort of like backwashing a pool filter. If you blow down it guarantees as much intimate contact as possible because the beads cant move. It could be theoretical but why not give yourself every advantage possible?

The only inconvenience is the need for a screen on the dip tube. I like to use a large sintered bronze air muffler but nylon window screen should be fine.

Thank you all. I will share (and ask more questions) when I actually start to tackle this... Good thing there was a mention on the beads... the two air dryer kits came with all blue beads... I will order orange beads and get rid of these blue ones...

Strictly speaking this has been a purchase over a few weeks.
Six weeks or so back I bought a backplate and small surface plate from a local fellow.
A couple of weeks later he messaged me asking if I knew anyone that wanted a lathe project.

Being the curious sort I asked what kind of lathe.
A Busy Bee DF-1237G but it needed repairs.

It’s in excellent condition with no visible wear. Two chucks and both the steady and follow rests.

While changing the drive belt they broke the counter shaft casting.

I decided to take it because I figured that I could re-make the bracket with flat stock and I’ll end up with a lathe I know inside and out for total cost of $300.

Great find and idea on the repair.



That looks very much like my Enco lathe. In the past someone did some creative wiring. If for any reason you take off the control panel could you please take pictures and where the wiring goes. A run down of what each switch does would be helpful. Mine just has a toggle switch in a electrical box that the motor plugs in to, the original Plate and switches are long gone.
 
This is what I used. My dryer holds 2 quarts so this gives me a dry bead change without having to bake them right away.

My aftercooler removes so much moisture I don't feel like I need to use the dessicant dryer for the whole system. I set it up as a portable unit that lives with the plasma cutter and does double duty as an air polisher for spraying paint.

A desiccant dryer is good for point of service polishing even if you have an air dryer.

Wachuko, the machine isn't going to care about entrained cobalt salts. Besides, the desiccant should be between the coarse and fine coalescing filters that you already purchased. The blue when dry, pink when wet desiccant beads use cobalt chloride (a rapidly absorbed toxic salt) as the color indicator.

You will need to periodically maintain your desiccant by pouring the filter media onto a cookie sheet and baking it dry. I do an hour at 325, like a cake. You don't want to make cookies on that baking sheet or eat them, but if you take good general precautions while handling it, it's okay to use. Wash the cookie sheet with soap and hot water and don't tell anyone what you did, and all will be well.

I have a big air dryer, so desiccant can be disposable in the small polishing filters for point of use. The only desiccants that I rejuvenate regularly are the 10 lbs of green to orange for my gun safe.

Will do!
If I recall correctly there is a wiring diagram somewhere here. I search for it and ping you if I find it.

Firsty, did you guys have a bad day with the yellow paint? I'm fairly sure I've got my people straight, is it you who has the JD2 set up vertically in a similarly painted mob box? It makes it easy to spot, which is maybe why I thought I've seen it before. It's like Jackson Pollock's version of painting tools, but he never used less than three colors.

Yes, saw a video on how to make one out of one of the large water filters that I have:

ARRRG! Was going to watch the video in the link. But remembered that a this weekend my main board audio died! (Both front and back panel.)

A few weeks before that the PS2 mouse and keyboard inputs died also. This system suddenly isn't letting me see SMART on all the drives now too. Apparently this system isn't long for this world...

So, what did I buy today:
Core i7-13700K
2x16Gb DDR5-6400
B760M-CT-CSM (Asus Pro)
990 Pro 1Tb (Samsung)
Hyper 622 Cooler
RM750e (Corsair)
Define R5 Silent Black Case (Fractal Design)
Using an old Quadro CAD (Not a gamer)

A lot of CAD is single threaded and the 13700K hits about the best price vs. performance for single threaded applications right now.
Unfortunately, the board doesn't have any PCIEx4 slots, so the 10gig fiber network cards might have to go bye-bye. So it's either a Quadro Video, or dual 10Gig fiber card... ...Maybe onboard video is enough...

Really been trying to justify a CNC plasma table purchase. Not happy because this is cutting into the funding for the plasma table. So, this weekend decided to order parts I needed cut from a buddy rather than buy a CNC table. Picked them up on the way home.

FYI. I HATE COMPUTERS!

Yes, thats my JD2 bender. I eventually get around to a sloppy yellow paint job on the drawers just for the odd looks I get. Hard to tell but the 211 is barely 50% over the black.
