Very neat

Support brackets for climbing plants,had to match an existing pair in Wrought iron,20 & 16mm square.

I made this old air pump suck twice as much.


I've had it in my treasure pile for years waiting for a use. It occurred to me today it might work for vacuum filtration, so I stuck a gauge on it and the needle was bouncing between about 375 and 500 Torr, which dropped back to zero almost immediately. I took it apart expecting to find the diaphragms all perished and leaky but luckily they were fine, the reed valves however were seriously manky:



The tar came off easily enough but the sealing faces were corroded and pitted so I cleaned them up with wetstones, working up to 8000 grit, much better now (I didn't bother cleaning the pitting off the back face).


Tiny drop of light oil should keep them sealing tight, all back together and it easily pulls 625 Torr, which takes a few seconds to bleed back down to zero now. I put another gauge on the output and it makes it to 40psi before the PRV opens, not bad at all. No idea what it's rated for, where it came from or what it was used for, quality little unit though. There's a small leak where the diaphragm meets the casting, it's not a machined face so I might pull it apart again and see if a light skim on the lathe can get it to seal, maybe get a few more Torr out of it.


I of course had to try filtering something so had a rummage around and found a cute little side arm flask, a bung that didn't fit it and a narrow stem funnel (Exactly the type you wouldn't use for filtration). Cut a circle out of a coffee filter, filled it with cutting fluid, fired up the pump and it pulled it through in less than a second.



Looks like my cunning plan is gonna work, next job will be to make a big special Büchner funnel, something like this:

Stay tuned.

What are you filtering with it?

 

[Maker]

What are you filtering with it?

Foodstuffs mainly, all that Heston Blumenthal, molecular gastronomy crap.

It was actually dashi that's brought this on, there was a bit of stuff which passed through a sieve, I tried a coffee filter but it was taking forever so I just left it in, it didn't matter and the soup was delicious but it would be nice to have the option to easily filter broths and things in the future. My main use will be cold-brew coffee, I make a litre at a time and it always blocks normal coffee filters, which takes ages and usually needs the paper changing, it does need filtering too as I store it in a cream whipper under nitrogen and fines might make the valve leak. This setup should allow more area of the paper to actually filter, hopefully reducing clogging (In a V60 or Chemex there's really only a small circle at the tip of the cone that actually does any work), the extra force should make clogging less of an issue and generally speed the whole process up too. I asked how to solve this problem on here last year and was met with a resounding "Stop making cold coffee, you freak".

3D print a funnel with drainage grooves on the inside , running into the funnels spout . .. giving you numerous ports & gullies for drainage down to the outlet pipe

Make the grooves inside the funnel like these external ribs

I don't believe in 3d printing.


I did try a pleated filter though, it wasn't much of an improvement.

You'll never know if it would work then .

I have a big 250 mm wide 250 deep multi holed stainless steel made of sheet metal as a cone strainer ( Hundreds & hundreds of 1mm holes ) for wines & juices , it was only when I put a nylon mesh cone insert in it followed by two thickness of Jaycloths inside the nylon cone that the filter started to work well.

The larger surface area available for straining is the secret

I had my first go at laser engraving. Quite pleased with the outcome. Lots to learn etc but enjoying the experience
100mm square plywood coaster, 28% power, single pass.

I did some work on the pressure pot for sandblasting that I bought, the mixing valve was so small it was difficult to work, I got one with a bigger lever. I also had to replace the compressed air connection so I also put a valve there, really should've been like that from factory I think.

I am working on converting my blast cabinet to a pressure blast system since I hear they are so much better. The old suction gun was converted into an air gun, no point throwing things away.

I put the old mixing valve on the blast cabinet, but I had to make an adapter.

Shed's still under construction, but I'm putting it here.

I reused the cap and nozzle from the old suction gun and made an adapter so it's just connected directly to the hose now, I use the valve on the side of the cabinet to turn it on and off.

Of course when I was going try it, I wasn't getting any medium (glass beads), or it came in starts and fits. I had to open everything up and when I looked into the pot I saw the whole was covered up completely. Had to remove the bottom mixing valve and out came this round piece of stiff plastic that had perfectly covered up the hole into the mixing valve. No idea where it came from. Well I gotta wait for the loctite sealer to cure again now. Hopefully no more issues.

Well not today but Helped my pal out folding a staircase. Bloody awkward manhandling the bigger sheets:





These above are 2m x 1.5m and 6mm thick. I was bushed!

Today I made A mess sorting out doubles

 

[Munkul]

Made a leftover stainless steel tray fit the "heavy" which has just been painted this week now I've actually caught up with stuff needing done. Holds all the carver tee slot clamps etc.

Nicely designed and made table, is that alu extrusion on the top ? Steel ?

Nice table anyway, nice drawer. Damnit, all nice.

Thanks no actually its a machine bed with tee slots. The white paint on the side of it makes it confusing to look at but i didn't want to paint the bed as well as the frame. This might give a better impression
