30 bar? 🤣 That's 30 Hg. That equals 1 bar. There is an outer scale in Hg and and an inner scale in bar. 0 represents 30 Hg/1 bar normal atmopspheric pressure at sea level. That means 30 Hg (29.92 at exact sea level) on the dial represents actually 0 Hg or a vacuum. Near vacuum, actually.
To do the knife scales, i want to preserve them because I ve had this lockback made by schrader called old timer, well she's a very old timer and the wooden panels i dont want to remove as there just stained wood! Thats it, no lacquer finish or anything just dryed out wood . So can I just get a brush and saturate each panel, one side at a time then put the old girl in the chamber and maybe run it like that for a few coats until its impregnated? Im not worried about the runs of excess from dripping down the sides as i can fix that. What say you sir?
30 Hg on this kind of vacuum dial refers to 0 Hg / 0 bar because the -30 Hg would be less pressure than vacuum which is not possible. 30 Hg or 1/bar is atmospheric pressure at sea level. On the vacuum gauge the scale is reversed!
Wasn't there a filter to put on the other side of the valve? Just trying to remember. I have no idea honestly on these things and have been reading reviews/watching videos, doing a ton of research. And these pots with the acrylic lids aren't good for the whole wood thing and the cactus juice - the chemicals will degrade the acrylic lid in no time from what I've read in what instructions from the manufacturers have said - you need a tempered glass lid for doing the wood or that type of item. This pot is more just good for resin/epoxy and silicone molds, I think. But I could be wrong. : )
TBH I don't have much experience with other finishes other than epoxy with these pots. It has been really good for what I use it for. Only downfall for me is the pot's size. Wish I could do 2 gallons at a time, but it still works for me! Thanks!
The pumps vacuum exhaust needs to be loose or open, preferably loose & usually has a fiktet inside & its strlngly recommended to run pump 20mins & drain & refill for firat time as break in process, as an hvac tech my 5cfm punp vs $ratio is rockibg solid i gotta say ive used damn thing for all my side jobs with some long as line sets kn splits & mini apkits multi zones & grt it down to as manufacturer recommended spec of 500microns or under, once again im a big fan of old mighty yellow jacket bullets but the bullwts arw $500 for 7l7 or 8cfm pumos & quality has declined for bullets so i tried this foe da heck of it & i gotta say so far i like da damn thing, but lets see how long it goea, & this guy is iusing a bar micron gauge ehich just really make me want to laugh like really, that gives u absolutely noooo precision whats so ever, once again p3ople micron gauge is the only tools that should be used on vacuum pumps yo actually see what these punps are doing, yes a quLity mictkn gauge which is not too cheap unfortunately but u gotta spend moneybto make money
I’m starting my first resin river furniture project. My first tests have been bit of steep learning curve! Loads of air bubbles. Thought about getting this exact kit. Got on here and looked for some guidance. This video has been brilliant. Thank you for taking the time to explain everything you went through getting this all set up and how you’ve taken the time to get rid of all the bubbles! Feel confident in getting this kit. I’m off to watch the rest of your videos. Feeling a lot more confident that my projects will succeed now. Thank you. 🎉
Hey! thanks for the video, I've really been struggling with the dang bubbles!! I did get this same vacuum and was frustrated bc it felt like it was adding more bubbles to the mix rather than removing them. But watching this it looks like maybe I didn't cycle thru enough? I only did it a couple of times before stopping with a cup full of foam. It looked like you did about 10 rounds of the vacuum, is that right?
I found the best way to eliminate the bubbles fastest is to do 2 quick rounds of suction and release, then put the suction as high as you possibly can the 3rd time and leave it alone. In a short period of time it will pop them all. I try to find something else to do for that 10-15 minutes as a distraction! :) Thanks for your comment!
I don't think you would have time with table top epoxy. To be honest, Ive never had problems with getting bubbles out of table top because of how thin you pour it. Usually just a blowtorch will take care of those pours!
Hi from Denmark. Thanks for an absolutely fantastic video... you got it son ! 🙂 You totally nailed it and showed me exactly what I wanted to know. I love that you really overdid it with the amount of air bubbles introduced to the resin... just to show if it could be remedied with the vacuum pump. My only question is if you can tell how much oil this thing uses, and, if just 'any' vacuum pump oil can be used to refill the thing?
So glad you enjoyed the video. I have used my pump about 15 times and it is still full of oil. However, I did notice that once you leave it set for a couple days, after each use, it will seap a very small amount out the cap. Not sure why, but hasn't affected the unit at all.
