I think I am in the right place but if not can someone move me. So for my project I want to make rotary sifter. Using two sheets of 1/4" mesh and attach them so they make 1/8" squares. I want this to be permeant and sturdy. I think the best way to attach them together would be to solder it.(I am open to other options if there any) But I don't know what soldering kit/solder, seeing that this would be my first time soldering something. What would you suggest? links to the products would be great thanks

If you want 1/8" mesh, buy 1/8" mesh, don't try to layer different sizes together to get what you think you want. The problem here is that material will become trapped between the layers and plug up, it won't give you a actual screening of the desired size.

As for "soldering" your mesh screens together, solder only works on certain materials and conditions, and for what you're asking, solder is not the correct form of bonding for the job.

Plus you'll be dealing with zinc coated wire which doesn't solder

The do make 1/8" mesh.

Besides, how can you get 1/8" squares by over lapping 2 pieces of 1/4"mesh. Let me brush up my math and geometry - still don't know how.

Oh I did not know that then I will have to find a better way to replicate what I did for my prototype. I kind of assumed that is what it would size would be.

What are you doing that you need such a fine mesh? 1/4" is really as small as you'd need for most applications

a cat sifter, once my cat has gone pee the pellets turn in to saw dust type material. The pellets easily fit through the 1/4'' mesh, but putting them on top of each other so that each square turns in to four squares has done a awesome job sifting through the litter. and the reason why I am wanting to make a rotary sifter using the mesh is about convince. Currently the mesh is in the bottom of a bucket and I have to shake the bucket to sift the litter, which is somewhat annoying as I have to shake the bucket some what hard to get it to sift.

Gotcha!

Definitely get yourself a smaller screen, don't try to double up the material, it just won't work well. Let us know how your project works out.:cool:

tylercc,

You might want to look at some of the diy sifters as illustrated in the You Tube videos, as below---there are quite a number of different diy designs, including diy motorized ones you can choose from; take the time to look at a considerable number of the videos before you settle on a design that best suits your needs.

They make scoops. If you want to spend more money, you can get a kitchen tool that is used to lift food out of a deep fat frier that has 1/8" square mesh. I have one for cooking. I use a plastic scoop for the cat litter.

If you want to spend a little more money (maybe less than the kitchen tool), they make a three piece litter box. The top box has a screen bottom, then two solid bottom trays. You stack the three together, fill with litter. Then after use, you lift the top tray with the screened bottom and sift out the unused litter. Toss the pods and solids. Lift the middle tray out, put the screened tray on top of the bottom tray and then pour the unused litter in. Then put the empty tray on the bottom for the next cycle.

interesting enough I have not had a big problem with litter getting caught in between the two sheets on my prototype.

youtube is where I got the rotary sifter idea, and how it sifts is not a really a big deal. From what I can tell getting the right screen sizes is going to be my biggest problem unless I over lap them like I did in my prototype.

Because if dj1 is right about the two over lapped pieces not giving me 1/8'' then I don't know what size it is. and I have tried the next sizes down from 1/4'' at lowes and that did not help any. so unless there is a way to measure it then I am kind of up a creek without a paddle.
