Chamber flush system build log.

You can get just the pump for $235 from the same place.

Then I wouldn't have a tank. I'd have to use a bucket. Then again, a bucket would save me some fluid

for those interested... the Graymills part is IMV08

They list some alternative part numbers, all of which are currently out of stock. I'd call Ajax and see what they say.

The Graymills version of the pump, if you want 115/230 VAC is IMV08E. IMV08F is a 230/460 VAC pump.

Here is similar option with the same specs:

I have no trust in "usually ships in" statements on Amazon unfortunately.

Looks pretty complex compared to mine.

Ditto, I was wondering why the additional hydraulic hose attachment connecting the rotary union to the muzzle flush device, mine's connected directly as is yours. To each, their own

 

[LVLAaron]

I didn't want the weight of the rotary union, hose, etc hanging on the end of the barrel.

I have my rotary union mounted on a stand with a 16" hydraulic hose going to the barrel.
For $35 and shipping I'd get the Graymills pump from Ajax.

2 gallon buckets are easy to find. Any hot dog hamburger joint gets pickles in them.

For a stand search microphone stand or light stand on Amazon

I've been pondering building a flush system and was thinking about using this fuel cell as a tank. They also sell a 5 gallon one for about $20 more.

That looks like an easy solution. Some oils will react with aluminum but as I understand it it just discolors the aluminum. 2 1/2 gallon capacity is plenty. I never completely fill up my 5 gallon tank.

Just read it has a foam core. Probably wouldn't work well with oil.

 

[LVLAaron]

also has AN fittings. Might be annoying.

 

[DaveTooley]

For the guy doing his own work I keep circling back to a 2 gallon pail. 9 1/4" tall
Maybe a 3 1/2 gallon with a screw on lid.

AN fittings are nice. You can put them on hand tite and be ok in this application

Foam is loose in the tank and can be removed through the fill hole.

A 3.5 gallon would duplicate the cheap Chinese system that Ajax has, except a better pump can be used. I get a little concerned about the weight of these immmersion pumps (15-20 lbs?) on a flimsy lid, but someone probably makes a better bucket.

Cut a plywood ring to sit on top of the lid. You're not going to open it up often. For the amount of work I do a good pump is essential.

We now know the foam can be removed. That's makes it an easy decision.

@LVLAaron: What a cool project! A lot great suggestions by others as well.

Asking for a friend... If someone is lazy or maybe has very little time to fabricate and test, is this project as easy as ordering a Gre-Tan BTS kit, one of the Pen Tool's coolant tank/pump combinations and cobbling together a catch pan and return line plus a modicum of plumbing it all together?

Even if that solution required retraction of the reamer every .050 or so to allow chips to flush by, that would save a lot of time.

Depends on what you're going to run for cutting fluid. The centrifugal pump with my Grizzly tank wouldn't push my cutting oil (dark w/ATF) at all. If you're running light oil or synthetic with much lower viscosity it's less of an issue. You just need to make sure the pump can push your cutting fluid of choice against the head pressure and restriction of the bore. Plus, I think a return line to help regulate flow (and in my case with a pressure impeller pump it greatly reduces cycling) is a big help.

Seems like you could certainly get by with that. Depending on your lathe... you could swap the coolant pump with the Graymills we've been talking about and just add the gre-tan bts thing... Let the oil run through your chip pan back to the pump.

True. It's a plumbing project though... I figure more types of fittings would be annoying. They would certainly work though... and that fuel cell is a lot cheaper than the hydraulic tank I got.

I used a $5 3 gallon rubbermaid tote. Couple thru-hull boat fittings.

Ace was cheaper than this one at tractor supply
