- Using a custom made vacuum fixture as a work holding method. This video will cover my journey with vacuum fixturing. This new setup has reduced cycle times and sped up my production workflow. To pull the vacuum I use a vacuum pump that I bought off Amazon.

What will that vacuum pump pull down too?... Martin
Hello Martin it’s so nice to hear from you. I can get it to vacuum down to -0.85 or -0.9 bar. Not nanas for the money but it needs to cycle in and out. 🍻 Aaron
Good job. I wouldn’t worry about the temp of the vacuum pump. I run mine (JB & Yellow Jacket) for 24 plus hours straight. It does get hot though.
Excellent point. Since that video I bought a timer and run a 50% duty cycle. Cheers 🍻
I just used a length of 4" diameter PVC pipe plugged using standard PVC end caps on both ends to make a vacuum tank. At full vacuum, the differential pressure is only about 14 psi so it's relatively very low. Leave the pour leprechaun alone ya greedy mooch. :)
G’day Stephen. That PVC tank is a bloody great idea. I didn’t think of using that. However I had the son-in-law’s gas bottle here so I pinched that instead. Oh don’t worry, that little leprechaun 🍀 bastard is still hiding tools on me or knocking them off the bench everyday 🤣
Wow 27 cents a KW here in Oklahoma USA we pay 8 cents plus another 30$ month in extra charges
G'day Neil. Yes we Aussie's are getting rooted in the bum over here for electricity. We have shit loads of coal, but that's dirty and nasty according to the leftie snow flakes. Oh well, that's the price we pay for a privatized network and vast country with only 25 million people. Thanks for watching. Cheers, Aaron.
That Premier down there has a lot to answer for with his lockdowns.Seriously mate a public figure like yourself should be allowed to travel far enough to get a haircut.God knows you need one bad being in front of the camera.
G’day Micheal. You’re not wrong mate. I was booked in for a haircut on Monday, but we were back in communist lockdown 🤦♂️. Di’s made another appointment for me this coming Monday 👍🍻
Great video Aaron! Was that you machine making those sounds or were the cartel pups doing shots????
G’day Paul. Thanks buddy. Nah, the noise was coming from the Columbian Chihuahua Cartel. Mossy was doing a cocaine deal that went bad 😂
Hello, how do you empty the lpg rezervoir?
Good question. If I need to do that, unplug both lines, too upside down and shoot compressed air in one port only. This purges the coolant from the second 👍
Gday Aaron, that’s a great setup and it won’t take long to recoup your money back also if a part fails there all common components, having this setup really speeds the operating up, great job mate, cheers Matty
G'day Matty and thanks mate. Yes this set up works a treat now. it only took me 300 parts to get right. As you can see I'm not that smart but I can lift heavy things LOL. Jokes aside, I can't believe how fast I pumped them out once I got going. I was up and down like a yo yo all day. Cheers, Aaron
Nice setup Aaron. I need to make a vacuum table. Good video again
Hi Mark. It's very easy to do mate. I forgot to say that I got the O-Ring rubber from Clarke rubber for $5 per metre. I can't believe how well it actually works. Glad I used the gas bottle as a reservoir though. Cheers, Aaron.
Great setup buddy! The production increase you've gotten from this made it all worth it! Wow. Huge improvement. I have a carbon vane vac pump here that would do that job easily......runs quiet and continuous. :)
G'day Mike. Thanks mate, I'm really happy with how it turned out. And like I said it easily dropped a day out of my production run. I will look into a carbon vane vacuum pump.
...
I trust it's nothing like your "blue veined junket pumper" (google it, it's Aussie slang). I've been told that it's also quiet and continuous. LMAO
@@DCT_Aaron_Engineering Yep...nothing like.........you won't be as excited to put your lips on this one. ;) lol
Your Syil is so quiet! Oh, wait. Maybe that's in post production. It's still likely to be quieter than my Sieg. The screaming banshee.
G'day Mark. Yes I had the volume turned down -15 in final cut pro, Otherwise it blows the ear drums out of my viewers. Your Sieg does alright. Definitely brings more capabilities into your shop. Thanks for watching Mark. Cheers, Aaron.
@@DCT_Aaron_Engineering I can't find the volume knob on my Tormach 1100. Maybe I need to buy the kit from them.
@@danl.4743 G'day Dan. I'm sure they'd sell you one if you rang them LOL
Errrrrr.... ‘outtakes’ 🤪
G'day Robert. I got your emails yesterday. Love that rolling saw stand you built. I should have put my order in for one LOL. I was a bit dubious about putting the outtakes up. That's way I put the warning up. Don't want to upset the snowflake generation. Cheers mate, Azza.
Great vid Aaron 👏
You’ve given me some ideas 🤔
Is the CAD file on the Syil table available?
Loved the outdoors-takes 😂😂
But you’d better watch out that the ‘dog-and-fat-kid’ protection societies don’t come knocking
😎
Hi Robert. Sorry for my belated reply. For some reason you comment was automatically placed in the "held for review" comments which I only see when I log in on the computer. Yes mate I will send the Syill Table file over to you. Cheers, Aaron. PS: I have carefully place crowbar waiting for those crazies if they come a knocking LOL 😉
That vac pump was cheap too think I will grab one. Can you send the Amazon link please
G'day Mark. Sure mate here is the link here: www.amazon.com.au/BACOENG-Single-Vacuum-Conditioning-Refrigeration/dp/B08DLHQPN9/ref=sr_1_1?dchild=1&keywords=vacuum+pump&qid=1613464111&sr=8-1
Loved it Aaron! Hey, why no vacuum on the vertical plate?!👍🏻👍🏻 for the Italian tap 😉. Ciao, Marco.
G'day Marco. Yes that will still need to be done. I ran out of valves to do it and the cost of airline fittings, manifolds, and valves are very expensive. That's a next time job. Cheers mate, Aaron.
@@DCT_Aaron_Engineering Roget that, Aaron!
Nominating you for the national treasure award, Aaron. Keep up the good work but especially the outtakes.
G'day Aaron. Thanks for watching buddy and I hope I gave you a laugh 🤣. Gonna try a different approach with this channel from now on and try not to be so formal. This is exactly what I'm doing with my other TH-cam channel "Aaron Engineering". Have more fun. Cheers buddy, Aaron 🍺
Nice Video as always Aaron - very well presented - what a great time saver !! Must be a pleasure to work with 😃
G'day Sam. Great hearing from you buddy. Trust you've been well and getting closer to running your large CNC router. Yes the vacuum table has really sped up my production. Cheers, Aaron
Hello Aaron,
You've done a good job there... Very interesting to watch...
Take care.
Paul,,
Hi Paul. Thanks mate, I'm very happy with the finished product. It has really sped up my production times that's for sure. Trust you are well over there? We are back in lock-down now. Hence the reason for my "inappropriate" outtakes LOL. Cheers, Aaron.
@@DCT_Aaron_Engineering All good here... still in lockdown but the numbers are going down at the moment and the vaccine rollout is going well.
@@TheKnacklersWorkshop That's great to hear Paul. Hopefully they will get it under control in the UK very soon and life can return to some normality. Cheers, Aaron
You can get a cheap used SMC pressure/vac controller on Ebay or a Chinese clone for a about USD20-30. It's a really simple set up where the vac controller triggers a solid state relay to turn your pump on/off according to whatever target pressure and hysterisis you have set on the controller. I have this on a similar setup to yours though I am using it for vac bagging composites and the SMC controller is great to have.That way, you actually don't have to remember to turn the pump on or off, it will take care of that for you.
Also, good on you for remembering the check valve as these pumps don't like to start against a vacuum.
But some builders take it one step further and add a 3-way solenoid valve between the pump and the check valve to vent the pump side so that that when it has to restart, there's no vacuum at all to start up against. This should prolong the life of the pump. That said, I realized my pump (same style as yours though smaller) actually leaks/vents slowly by itself when turned off, so I don't actually need the solenoid. Perhaps yours does as well?
For more on the solenoid venting google "Joe Woodwork Vacuum Pump" and a build manual and reasoning for the various parts should show up. Basically, my setup is a simplified Joe Woodworker pump with a more advanced vac controller.
His design even has a smaller pre-resevoir before the check valve. IIRC that's so the "shock" to the pump once the check valve opens is reduced. Again, it's a "be kind feature" that should help the pump live longer. Now, I also think builders used to use Gast or other types of much more expensive pumps whereas these Chinese HVAC pumps may be cheap enough that you are OK with simplyfying the setup and change the pump once it dies.
Hello and thank you so much for your concise and detailed information 🙏. Yes my good buddy Micheal Connor woodwork also put me on to “Joe Woodwork”. He has some great ideas. Oh I agree, I desperately need that solenoid switch. This was my very first attempt at vacuum fixturing inside of a VMC. I was blown away by results and it saved me a ton of time. Thanks again for stopping by and engaging in the conversation. Regards Aaron 🍻
@@DCT_Aaron_Engineering You're very welcome.
I am using my pump without a pre-reservoir and venting solenoid but even though the pump hasn't been used that much (perhaps just 50 sessions all in all with a handful of cycles per session), it does seem to have a harder time starting up sometimes now.
So, I think my pump has taken a beating already. If I had to speculate, I'd say it would be partly because I am using the smallest pump I could find as I wanted the setup to be small but mostly becuase I set my target vacuum to be as strong as possible and the hysterisis quite narrow, so once the vac has dropped a little, the pump kicks in but it does so "against" a reservoir that may still be at -0.8bar so when the check valve opens - which it does almost immediately given the tiny air space before the valve, I imagine the pump gets quite a shock.
I saw someone mention PVC tubing for reservoirs in the comments. Once you look into Joe Woodworker pumps, you will see plenty of examples of exactly that:)
You have reignited my interest in Joe Woodwork. I’m definitely heading back to his website/ forum and investigating more. Yes, my pump ran pretty much continuously for 8-10 hours without a hiccup. I thought for a $120 Aussie, it was great bang for buck. It beats running the air compressor flat out with that silly little vacuum generator that I bought. Enjoy your Sunday. Regards Aaron 👍
Nice job Aaron. What gasket material did you use on your palate to seal the work keys down?
G'day Rob. Silly me forgot to mention that. I went to store over here called Clark Rubber and bought 2m of 3mm black nitrile rubber O-ring cord. It was cheap at $6 per metre. I first went to the bearing shop, but they didn't have any. Cheers, Aaron.
@@DCT_Aaron_Engineering thanks mate, I just asked on the group as well lol.
Cool stuff. Very good explanation. Just subscribed!
G'day compass Precision and thanks for subscribing. I actually have another channel called Aaron Engineering which you also follow. Not sure if you realized it was the same person LOL. Hope you are well over there in the USA. Take care and talk soon. Cheers, Aaron.
@@DCT_Aaron_Engineering haha I didn’t realize you ran both channels! Sorry that didn’t occur to me, but it’s no problem following both your channels. Hope you are well in Australia!
Top video Aaron! Thorough and interesting.
G'day Livetools. Thanks for watching fella's, glad you enjoyed it. Cheers, Aaron.
Great video Aaron. Doggy looked a bit worried at the end!
G'day Grant. Thanks for watching mate. I'm proud of this small achievement from the Humpty Dumpty machine shop. Yes poor old Mossy got worried once he's tail was lifted. I think he's been operant conditioned from the VET. A bit like us Victorians under Chairman Dan. Oops no, that's Stockholm syndrome LMFAO
Nice
Hi Daniel, thanks for dropping by and for your support mate. Trust you are well? Cheers, Aaron.
@@DCT_Aaron_Engineering not to bad
great job mate ! - We had an issue years ago where it would suck 1/2 the coolant into the tank - ha ha
Thanks for following along Ed. Yes mine sucked a little bit at the start, but vasoline on the rubber solves that problem (I hope that comment doesn’t get misconstrued) 🤣
@CMTeamCobra Yes great idea. I had actually thought of adding one as your suggested (airline water separator). That way I could keep an eye on during the productions cycle. Cheers, Aaron.
First!!! Great answer and video!
G'day Gil. I've been meaning to call you for days / weeks now and keep forgetting. Please forgive me mate. I hope you are both doing well. Hopefully we can catch up soon for a chat buddy. Cheers, Aaron.
@@DCT_Aaron_Engineering sounds like a plan...
@@LaserLivestream look forward to it Gil
It’s cool. Found the pump
Sorry I was too slow.
nice fixture
Hey buddy. Thank you very much. I just watched your video on the Corvette you machined out of timber. Nice job mate. Send me an email if you want to swap stickers (or if you just want some). Cheers, Aaron.
@@DCT_Aaron_Engineering Thanks, I have no stickers, I'm from usa, what stickers you have?
@@makosharkcnc7730 hey buddy, send me an email with your address and I’ll send you some (DCT & Aaron Engineering) stickers. My email address can be found on my about page 👍
