Coolant thru muzzle flush system

PJ/AIR/FIRE

Just like to get some input from individuals who do coolant thru the muzzle flush system. Im interested in which pumps you've used and what to look for in buying one. Also what setup used to connect the system to the muzzle end. Ive been all over the web and seen some nice systems which have given me direction. Any input would be great.

Thanks Ryan
 
The $125 is only for the swivel adaptor with the "nozzle" to fit the bore.....that part alone is about 10% of the cost of the whole flush system unless you already have a high pressure pump and all the valves and fittings to put it all together. The coolant system on most lathes doesn't generate the pressure needed from what I found in my research. I just recently bought all the major parts from Gre-Tan and was able to find the remaining fittings and valves at my local Ace.
I have a new lathe arriving Thursday and the flush system is going on it. Once the lathe is wired up and spinning, assembly of the flush system is next. I'll post an update once I get it all together.

Keith,
I considered putting the gretan system on my lathe. It would work with the lighweight cutting oil that I have in the reservoir but I decided that for chambering I need to stick with the heavy sulfur based fluids so I didn't do it. I'd forgotten why I decided not to do it. You're right. You'll need some sort of pump and a separate catch and return system from your normal lathe coolant system. More money.

Jerry,
All the parts certainly weren't cheap but I'm looking for a quicker way to chamber without sacrificing quality. I've also been using the thick sulfur based stuff....I don't pre-bore so based on feed back from the reamer and the depth I'm in the hole, backing out and cleaning have been a way of life. After talking with a few smiths that build and shoot match grade rifles using a flush system, I decided that a new lathe in the shop warranted at least giving this a try. The speed at which these guys are cutting chambers amazed me. I don't do this for a hobby so time is money.

This was my adventure into building a flushing system. Looking at it now i see I never finished the complete wright up on it. I run vipers venom in it.
 
As stated, cooling is not our concern so much as fluid passing thru. We cut SLOW compared to most machining operations. Whatever pump you pick will be fine I bet. I use a small pump with a low flow rate. In chambering I back out the reamer 10 times I bet. Could be less but I hate chips :) The idea is to keep the chamber flushed. Flame suit on naturally.

Sorry about that, should be able to see it now.

I haven't found a coolant/oil yet that will keep the reamer from "squealling". So I've gone back to the old way of reaming, that is pulling the reamer out, cleaning it, and back in again.

The squeak in the video is from the belt. I had just replaced it and needed to tighten it slightly.
 
I use Rustlic 255R cut 5:1 with distilled water. Rustlic 255R is no longer available. The engineers told me to switch to UltrCut_Pro. at a 10:1 Ratio. I use a 3/8" 1/3 hp carborated gearhead pump with a 125 psi pound bypass. Have been using the system for eleven years. Have 3 reamers with over 2000 chambers cut with them. They have never been reground and cut great chambers.

I use a whole house water filter 5 micron filter (rated at 125 psi). Use the wound string or foam cartridge types not the wafer paper filters. I back blow air through the filter when I am finished using it so it does not remain submerged in the coolant lubricant. I change the filer once or twice a year. Some years I do 300 barrels some years I do 200 barrels.

Another thing you need to think about besides extreme pressure lubricants is what effects they have after becoming air born. Breathing their vapors should be a concern.

What spin on oil filter are you guys using? Standard oil filters such as on your Ford or Chevy have a average 21 micron filtering capacity. I could only find one hydraulic oil filter that had a 10 micron capacity. I think most guys were saying 5 micron was needed? Can anyone give me a actual filter number for a spin on, 5 micron, filter with a 3/4 inch center stud?
