Through barrel flush project question.

[Shrek]

In a previous thread someone recommended using a power steering pump from the junkyard to build a system. If you have built one using one how big of an electric motor do I need ? Any particular steering pump work better than another ?

Do you have your lathe set-up, finally?

I wish ! I'm just collecting right now. I picked up a 3/4 hp Baldor motor and I'm hoping it's enough. The shop is late summer to winter. I have way more wants than I got gots ! I picked up a cart to build it on for five bucks and the motor for $15 .

And a bunch of end mills , two half hp motors , bottles of socket set screws , taps. I think I made out like a bandit but missed the rotary indexing table by a minute or two for $125

I'm using a very small hydraulic pump I bought off of e-bay for $50 and drive it with a 1/4hp, 1750rpm motor through a LoveJoy coupler. It'll put out more volume & pressure than I can use. I originally was using a B&S #3 gear pump and had to gear it way down as it just put out too much volume. the little $50 hydraulic pump is much better than the B&S #3.

A $50 pump sounds like what I need. I have a 1/2hp 1725 and 3250 motors I can use.

Get your lathe (and mill) set-up. Learn to become reasonably proficient running it. Cut a few chambers the 'old fashioned way', .050" at a pass. Then consider a muzzle flush system. Buying all this stuff now, ahead of time, makes little sense. There may be better stuff come along by the time you've become 'reasonably proficient' and cut a few chambers.

Or you could drill out and bore 90% of the chamber and take 10 minutes to ream the rest. I bet I don't spend more than 20 minutes drilling, boring and chambering all but the biggest magnums and my reamers barely get used.

Yeah Save up a little money for barrels. ( and reamers and a "FEW" other things

I'm working on everything I can. I have a reamer and barrel for my first rifle and I'll put in parts orders for the next two rifles as soon as I can see the finish date on my shop. Of course everything takes much longer than anticipated. What I thought was going to be a week or two for permits for moving the trailer onto the property took eight weeks and I'm waiting for a dozer for a week that was supposed to be on my property last Wednesday . In the meantime I'm working on what I can and taking the opportunities that come along. A bunch of end mills for $2.50 apiece was too good to pass up. A Millrite for $300 was another deal. An inexpensive through flush built and ready to go will be nice. I'm not waiting for my shop to be ready before I collect the tools. Nothing is on credit so as paying work slows so does work on my home shop and everything else.

I built a flood coolant system for my lathe with a 5-gallon bucket, a Little Giant submersible pump, some vinyl tubing and a Lok-Line magnetic base. I use Hocut water based coolant and this setup has served me very well.

On a whim, I decided to try and rig this system for barrel flush. I bought a Dueblin rotary union and a few hose clamps. The Little Giant pump is a centrifugal pump and doesn't make a lot of pressure, but does make a lot of flow. The system will continually flush coolant past my reamer. I've only done one barrel so far with this setup and I was scared to push it so I would run the reamer in 50 or 60 thou at a time, then back out for a few seconds to let the coolant flush past, but I never saw any chips that didn't get flushed during the reaming pass.

I'll try a few more chambers with this setup before I fully endorse it, but it seems to work fine and saves a ton of time.

Well you seem to be working hard on it and I think you will make it happen. To many guys buy stuff and never use it/get the shop. Remind me are you getting a building built or are you gonna do it yourself?

Has anyone tried a diaphragm pump like used on ag sprayers. For $50 you can get a 3 gpm @ 40 psi pump - might be less with cutting fluid. They pulse so wasn't sure if that would affect the reamer.

I wouldn't bother with used taps and end mills. They could be nothing but trouble, worn out, ready for the scrap bucket. I may buy used drill bits (3/4" and larger), but I can re-sharpen those, myself. Any thing smaller I buy new. Do you have a good quick change tool post and a good assortment of holders? A good vise and tool holders for the mill? A machinist level to level your tools when you have concrete and a roof? How about good chuck(s) for your lathe. Old, worn out junk ain't worth having and will only cause you grief in the end,,,,,,, especially when you have little to no machine experience to begin with.

I'm still working on the place to live but then I'll be building the shop. Probably a 24'x24' metal building well insulated and A/C that I'll put together.

They were almost all brand new in the package. I didn't buy the well used looking ones. I'm looking for an Aloris for the lathe and a 6" enco vise was on the Millrite. I've already picked up a 10" 4 jaw independent Pratt Burnerd chuck rated to 2300 rpm. No wear on the chuck. Looks like it was never used. Has some discoloration that I think is mostly dried oil.

Make sure to have the concrete pad under your machines reinforced with rebar and increased in depth , I went 12" and wish I had gone more and further out . 24-24 will fill up fast .

Better build that shop 1st It's more important I really should put AC in mine this year. I used to work on oil burning furnaces. They have a pump on them that I think I will try for a flush system. You can get them pretty reasonable. Try ebay

youre sure right about the 24-24 mine is 40-48 and seems cramped.

I'll take all your scrap end mills and drills, lol. Endmill Bottoms and OD can be reground and drills are even easier to fix up. No China stuff though...

The cost of my time grinding isn't worth it when I can buy a new carbide 1/2", 4 flt, center cutting end mill for under $25. They'd have to be BIG, bigger than I'd normally use on a 8 x 49 sized machine. The darned thing probably wouldn't turn slow enough to use a BIG end mill.
