Chamber flush system build log.

Why are you trying to get "all of it" before returning to the reservoir/tank?

 

[LVLAaron]

There's a lot of it... What's in the photo is the last 100 thou of 1 chamber.

I should have mentioned - The bottom of the bread pan is covered in them.

You might try an aluminum pan, if that one isn't. I think it will keep the magnetic field more concentrated and powerful. I've got a 40 mesh strainer in my return line similar in size to what you have shoved in there and it never plugs.

 

[LVLAaron]

I'll give it a shot. It is a steel pan. I might put a baffle in the pan or re-arrange where the drain is - what comes out of the barrel is super close to the drain, so stuff doesn't have a chance to get stuck to a magnet

 

[Ksracer]

You can see the spot half way to the front where my oil falls. Also, the larger the bottom of your pan is, the slower the oil will be moving towards the drain giving chips more time to fall. The really dark rows along the edges are very fine. They are the ones the long flutes take off the tapered case wall. The heavier chips are from the neck and shoulder.

Got mine up and running today. Figured I’d run it an few times and see what changes I need or want before I finish it up. This is full flow with the AMT 1/4hp pump. I’ve got 1/2 up to the rotary then 3/8 out to the barrel.

 

[LVLAaron]

Look at this guy welding stands and e-stop buttons!

 

[jkohler]

just used stuff I had laying around. Figured the the big stop would be a easy target if needed.

Looks good.

I went with a foot pedal after doing a test job.. I use a reamer stop, so when the reamer is all the way in there's no place for the oil to go so it makes the "feel" of the reamer stop a little squishy. So right before I'm at final dimension I up the RPM on the lathe, flood it with oil, and cut the last couple thou without the pump running.

 

[jkohler]

I really wish I could find a foot switch that wasn’t just momentary but I may order one and give it a try as well. I still hold the reamer and use a floating pusher as I like to feel what’s happening I haven’t used my reamer stop for quite a while just went back to a indicator for final depth. Will see how it does the next few days I’ve got a dozen or so barrels to chamber up.

[jkohler]

well apparently I didn’t look very hard for a switch. I only looked at what temco had to offer All order one and try it.

You beat me to it. I just got my final piece today. Looks the AMT 1/4 HP pump is perfect.

Going to find out if it’s going to work Friday all chamber up a couple and see how to does.

Try this. Put a foil baking pan or something similar in your catch tray as the first settling pond. Loaf pan or even a pot pie size pan would do. Make slits about an inch up on the sides to act as drains. The big chips will slow the flow down to the point that the small fines fall out. You'll end up with a grey mass in the bottom. When you're done chambering pour some of it out then let is sit for awhile. My roasting pan is angled on the lathe bed. One side has slits in the bottom corner for an overnight draining and the other side has slits about a inch up to act as a filter when actively chambering. I just turn it around. Gravity is a wonderful thing.

 

[LVLAaron]

Something like this? I've got hundreds of them in the shop. Handy for all sorts of things.

Yep
Here's mine after a day of threading muzzles. Note the magnets below the pan. Not many fines doing muzzle work. Kind of ratty looking. I may need to replace that one

Would there be any disadvantage to using the onboard coolant system? Just use the tank and pump (or upgraded pump) that is located in the lathe stand. It would be nice to not have to manage a pan and return line

No problem at all. Just a plumbing job. Does your lathe have a big chip pan under the bed? If it does it might be advantageous to put a smaller pan under the bed with a hose to the drain outlet. That would eliminate excess oil in the pan mixing with STUFF. Also you could raise the outlet and it would act as a first stage settling pond. An aluminum roasting pan comes to mind. A plastic storage container would also work. You're only limited by your imagination.

 

[LVLAaron]

On that note I might get clever and run my external pump through the factory coolant nozzle / chip tray. That way I can stick to only 1 type of oil/coolant and have a nice flow when I'm parting, threading, etc.
