Making a Compressed Air Manifold and Installing an Air Gun

[@buckhanan363]

4 successful holes from a HFT drill bit is a win in my book.

[@eclsnowman]

Just a small recommendation from an old hand at pipe fitting. Only apply tape after the first thread at the end. Otherwise you have a lot higher likelihood of getting pipe tape shavings into your manifolds or downstream equipment.

[@garym1550]

Well said. This applies to anywhere you might use tape, whether in air, water, hydraulics, pneumatic controls etc.. Many companies/industries do not allow tape at all because of this foreign material introduction possibility during assembly or disassembly of a joint. A Teflon paste could be used instead of Teflon tape.

[@Clough42]

Yeah, I try pretty hard to get it onto the first thread, but not over the end of the fitting. I think the most likely problem in this case would be if some debris fouled my $4 pressure regulator.

[@eclsnowman]

@@Clough42 yeah, for a blow off gun it's less critical. But sending a chunk of tape into calibrated or precision instruments will lead to some unwanted troubleshooting hours. Best rule of thumb is to just skip the whole first thread to avoid the likelihood of downstream contamination. Love the videos BTW. Always fun to watch your attention to details and process.

[@costarich8029]

Really like the practical tradeoff approach of if it fails in 2 years, print it again in plastic. If it fails quickly then make it out of metal.

[@chrisjh777]

Hi James, a tip. I use a small magnet to pin my drawings to the front of the mill head. That way, you have the drawing at eye level immediately in front of you and you don't have to turn away from the job.

[@Clough42]

Good idea.

[@bacca-jt1th]

Hi James. Just a little tip when it comes to thread tape on brass or s/s fittings. ( Any smooth fittings.) I learnt early in my life as a Plumber that if you drag a hacksaw blade over the threads on the male fitting 90deg to the threads before applying the tape it will stop the tape winding down the threads. This will put the tape between the threads much better. I have never had a leaking fitting in 50 years of plumbing. Just a little tip. Regards from Australia.

[@janeinarwold2663]

Price of purchasing the tap handle = all the air manifolds you and all your friends is ever gonna need. Price of making one air manifold yourself = priceless! Now thats a true machinist :-)

[@Richard-gh1gv]

James, totally agree with you on the use of Teflon tape, despite what the ‘experts’ say. I use the gas fitting tape a lot, thicker, stronger and usually wider. I used to run a fuel delivery truck and we were always told never use the tape, always use the Teflon dope. Not a super high pressure, but it was a considerable pressure when the pump was in high gear and the nozzle slammed shut. Well, the dope worked great, for about a week. Then the dope would start getting washed away by the fuel, gas was faster than diesel. Switched to the tape, and never had another issue. Nozzles threaded on, sealed, and stayed that way until they wore out and need to be changed out.

[@Clough42]

The Maxline air system I just installed called for two wraps of tape to prevent galling, and dope to seal. So far, that combination has worked really well. This system has dozens of plugs and fittings, and I haven't had any issues. I imagine fuels and solvents are a very different matter.

[@SlamminGraham]

The teflon tape works very well but you only need 2 wraps. Our lab actually tested various lengths of tape when I was in graduate school and 2 wraps was optimal.

[@johnalexander2349]

I'm going to take a guess, and say that that depends on the tape thickness. There's quite a range.

[@UnreasonableSteve]

@@johnalexander2349 probably depends on tape thickness, tap size, tap/thread wear and quality...

[@cduemig1]

It’s quite useful identifying areas where you have excess material. Reducing weight or in 3D printing material and print time.

[@joopterwijn]

Ruff up the threats a bit with a (piece of hacksaw blad) before you wind the Teflon tape on the fitting. Makes the tape ‘stick’ to the threats. Maybe a polycarbonate plate on the back of the mill to catch the chips and not spread them to the sporting arena. The see through polycarbonate will keep the space open and light can pass. Added, after writing the comment I started reading the others,…. The first one below mine gave the same tip around the Teflon tape ( 😂 🤩 ) small world.

[@reedbj06]

Excellent as always, thanks for sharing!

[@misterfixit1952]

One really great accessory I have for my mill is a Dirt Devil vortex vacuum cleaner that I dumpster dove. It's an upright push vacuum and I removed all of the unused portions like the bottom carpet sweeper so it's as small as possible. I mounted it to the wall next to my mill with a long flexible hose with a couple of different ends. It removes most chips almost as good as an air gun and being a vortex vac, it doesn't clog up and lose suction when sucking small particles. Also, the vortex cools down the swarf so it doesn't melt into the plastic.

[@stephanuhu963]

I enjoy your postings and envy your command of Fusion 360. Thank you for sharing so much with us. While it's aleays handy having compressed air available at the mill, for the mister, and blowing out blind holrs etc, I'd suggest a wet & dry vacuum routed through a centrifugal separator mounted on a bin, to clean up swarf. Keeps swarf from flying everuwhere, and is kinder to the DRO rails and elsewhere that you don't want swarf getting propelled into. Waiting for the snow to abate here in Nee Brunswick Cda, to get back in my shed!

@ Clough42. Being a computer guy, I am surprised you don't have displays at all of your major work tools. Not DRO's but just inexpensive LCD displays right on the machine or close by that would save you from turning around to look at your paper drawings. I tend to set stuff on my drawings and make a mess on or loose them. At some point I am going to try to do the same. I have to find the shop first ;) I have spent the last several years flipping houses. Now it is time to go back to my other love. My shop. Keep up the great vids.

[@heronvontremonia9975]

The lube should help with chip extraction, even if not really needed for the cutting action. I remember that, during my years of apprenticeship, one of the older guys was filling blind holes with thick grease for tapping. so that the stuff, squeezing out through the flutes, extracted all the chips. i am not 100% sure (it was in the 90s) but i think it was cast iron. informative and entertaining video, thanks for sharing your knowledge.

I "cleaned" a Bridgeport mill with compressed air once after a large cast iron milling job. Once. It made a horrific mess. The floor was black. The walls were black. The evidence of that day was visible in the shop for years.

A number of my older (70's era) engine building and remachining books from Chrysler. Specify using a paste sealer on oil galley plugs. Instead of tapes. The reason they gave for that. Is that the pastes can break down better when/if ingested into the valve train. Compared to the tapes. Which to them presented a higher instance of binding than the pastes. Which I have found fascinating since coming upon. I am sure there are just as many opinions that go the other way. But some fun food for thought. For those of us that enjoy it.

[@misterfixit1952]

You need to get some self-tapping drill bits. Also, in sheetmetal 10-32 and M5 are interchangeable, The threads are so close it's hard to tell them apart for threads shorter than about 1/2". I found this out while trying to mount my DRO with the wrong length screws it came with, at 3:00 in the morning. After digging around forever, I came up with the right size 10-32s that fit the M5s I'd already tapped into my mill.

[@MichaelLloyd]

Teflon is what we use in gas processing facilities. We use it on stainless steel tube fittings screwed into carbon steel or stainless steel on high pressure (1,000+ psig) connections. I could show you how to speed up the taping operation but your way works. I could do 5 to your one :) and I haven't done tubing work in 30 years. Once you tape a few thousand (probably more like 10 thousand) fittings you learn to do it quickly. But yeah... best choice when used right.

[@paulshermet535]

If I haven't said this before, I only use cheap silicone sealant for oil, water plumbing, air, exhaust manifolds (good for 1200 degrees), smear on gaskets so they come off in one piece if I use a gasket at all. Never leaks except with gasoline and harsh solvents. Teflon tape gets pushed off if the male thread starts tight. Cleans off parts with varsol or gas. Works good on bad threads and acts like a locktite that doesn't get hard and doesn't release from heat. Used it on connecting rod bolts in engines. Acts as alubricant until it dries. Don't need to wait for it to cure on air, oil etc because of the high viscosity. Not RTV silicone which very difficuld to get off and release. One more thing, inject silicone in crim connectors, before putting the wire in and crimp. No corrosion when salt water gets near them. Shrink tube lets water in an end if there are 2 wires coming out. Hatchtag: "not sponsored"🙂

I believe it's code where I live. It's plumbed with a short piece of PVC so leaking water will end up on the concrete floor where it will be noticed instead of leaking into the floor deck and framing.

Nice Video My first thought was why not have 2 ports on each side. The holes would then be thru and no depth to worry about, item could be slightly shorter to ease drilling deep hole. and that hole could go thru and tap the top for Gauge. I have never heard of having too many outlets for whatever comes up in the future, Speaking of Outlets, the Electrical Quad box face up on the floor is in a great position to collect conductive chips from the mill.

[@chip-load]

A suggestion would be to test the connections for air leaks using soapy water. You will be surprised how much air can leak from a “silent” fitting. The most expensive machine in my shop to run is the air compressor! I have searched for (and used) quality disconnects and they all “bubble” leak. The quality of fittings has diminished in the past years. I use Milton T couplers and they are about the best quality I can find. However, a link or name of any high quality, leak-free, coupler would be appreciated. Sometimes there are different quality levels within a brand. THANK YOU for the time and effort you put into videos. Your F360 presentation is always excellent. Your pace, clarity, and insight is way above the average. As mentioned, tying F360 to the current CAM project has a synergy that is not duplicated most.

[@37yearsofanythingisenough39]

Unless you have indicated the tops of those Kurt vise jaws, laying a 123 block on top of them has set that workpiece at some angle. Obviously in this case it doesn’t matter, but in a criticality dimensioned part it could cause major problems. The bottoms of the jaws do not always rest on the vise bed, sometimes intentionally for burr clearance and etc.. This means the jaws are aligned by the 1/2-13 threads of the socket head cap screws. Best results are achieved by coming from an indicated vise bed.

More expensive than the white stuff, but one roll is likely a life supply for the home gamer.

Quick, easy, and will last a long time. I like it. Have you thought about adding some kind of anchor point for keeping the sideways force off of the hose's end, in case you ever trip on it?

Maybe sometime you can make something about how you clean up the mill/lathe after showering them in chips. Do you recycle the shavings, etc?

You can make normal teflon tape work, but my system is mostly put together with gas fitters tape - it's a slightly heavier version of the same thing, as I understand it, and, if you think about it, it makes sense, as compressed air is, you know, a gas. I find it much more consistent.

There's actually really many "industrial type" air connectors that look fairly similar.

The pedants on the Internet will tell you to never use compressed air around machines because it blows chips into bad places and causes premature wear.
