Sieves

[zippo]

Not much happening here so I thought I may as well post some sieves I made just for fun .
Sizes are 100 , 150 , 200 and 250 . I was going to make a vibrating base for them but have to find a fast enough motor or step up system .

The sieves look good. Can you give a bit more info on the build?

Sorry for the delay .
Started with 10" PVC , cut 50 mm and 30 mm rings . Set up router to cut a bit over half the thickness , from the inside of 1 ring and about 8 to 10 mm deep on the corresponding piece . to allow for the mesh size . Bit of flexibility in the size .
Get the pieces to fit easily . Then I used a piece of ply , cut to fit inside the pipe work and pack to get the height of the mesh in the lower piece ( 30 mm bit ) .
Press the top down onto the mesh to get a cutting line around the outside of the pvc . For 250 and 200 mesh I trimmed it after the glue had set . .
When you have the mesh ready Fill the bottom grove and top groove with Sikaflex or similar , place the mesh and apply some weight then wait to dry .
Does that help ?

Thanks Zippo. Where did you buy the mesh?

From China , the wire size is small and the mesh is " soft " for the want of a better description . The 250 and 200 mesh are easily cut with stanley knife . Good service and price for testing the build principle .. I ended up with enough to make 6 sets of 4 sieves ,
