Heyyyya there everyone,
As a Millwright my background is mostly in metal working~metal machining~ and mechanical. But I do have enough experience with wood working to get in and out of trouble most of the time.
A couple months ago I stumbled across a brand new never used HF sandblast cabinet with 10~20lb bags of grit for 20$!(No not stolen~lol... wife was divorcing and was selling everything of his off cheap) Since the cabinet did not come with a vac/recovery system I learned really quick why you Do Need one in about 30sec of using the first time do to my whole shop was covered in grit dust! And Yesss I am still finding grit dust after about 2months later. Since I am the the kinda person that has a hard time buying something that I can take pride in making not only Bigger~Badder~Better but make last, I started researching on how to make a recovery dust separater for going on 2 months in my spare time and boy have I have learned a lot and also have been confused several times!
There is many ways to do this right and wrong. Everything from cyclonic~multiple cyclone~baffle system~ to axial cyclone systems like Dysonís vacuum cleaners. After searching page after pages~forum after forums this is the first forum I registered with after reading all of the posts here!
This forum has taught me a lot and has answered a lot of questions thanks to You and all of your comments and posts!!!! This forum not only actually answers your questions and helps you understand the ďwhat~why~whereĒ but dosnt treat you like your stupid!
So here is my question/questions and I feel real confident that Iím in good hands here!.....
How I got the idea for this was one night a while ago during some research on the inter~web I needed to a break to let my thoughts settle and grabbed the vacuum cleaner to vacuum up my shop floor and work benches ( yes I said vacuum cleaner not shop vac! Itís our old house one and works great 👍 for cleaning shop floors~better than broom and dust pan!!! Faster too) it does not have a cyclone or multiple cyclones in it but it is bag less..it is a cyclonic style. Iíll post pic of it... but anyway as I was doing this the 💡 came on and then confusion/dyslexia set in at same time....lol
I would like to build a bag less all~in~one system to reclaim~separate~and filter out the fine dust blast media or sand using a shop vac... I am not sure if I want to make an R2D2 pancake system or not yet. I have 2 different shop vaca. One is a standard Crapsman wet/dry 3.25 hp 8 gal one that blows exhaust out the sides below motor. The other one is a 16 gallon Hoover 2 tank wet/dry with a wet tank and dry separator switch that has 216 airwatts of suction (which I have found out that is a true suction reading vs hp~but I canít find what it converts to as hp) and has a blower accessory port but also exhausts like other on.
I learned from from a different sight that a cyclone system takes more to pull air through than Thienís baffle system.
So that being said... what I want to build (and since Iím trying to reclaim sand everything needs to be metal) since space is a problem Iíd like to try and build a cyclone inside either one of my 30 or 35 gal metal oil drum. Or I can build a Jp baffle top hat system or combine them both. But hereís the one of the problems I also need help with... i need to pull media/sand from blast cabinet and separate the media/sand from dust/garbage and have the dust in a separate container or compartment. Preferably on top of drum. I have drawings of what my thoughts are that I will post.
Has anyone tried putting a cyclone inside drum instead of on top like a vacuum cleaner?
Iím adding some pics of a horizontal system that I stumbled across and looking for thoughts on that too...
Shoot I canít upload pics from phone!!! This makes things harder! Grrrr help!!!
