This is a neat way to protect the axis of your mini cnc milling machine designed by Honus. It is a simple way to keep dust, grit, grime, and bits from clogging up the axis's of your machine.
Please read each step fully before you start so that you do not waste material.
I am not liable for any mistakes you make, errors that cause waste in resources, damage to your property, yourself, or others. Knifes are sharp, if they can cut, they can cut YOU.
CNC Machines are dangerous and should not be operated by people that do not have experience, knowledge, or any certification in this field. Take precaution when using these machines for they can severely injure yourself, your property, or others. I will not be held liable for anything you do.
By starting any part of this project, you agree to the terms above.
Step 1: Materials and Costs
- Redishade Temporary window shade Size: 48" x 72" x 1" price: $12 from The Home Depot. (links below)
- Permanent Fabric Glue (fabric can be washed after glue dries)
- Wax Paper
- Popsicle Sticks
- Bolts or screws
- Thin strips of sheet metal (About 2" x 3/4" :::6 of them:::) (not needed if you just spread out the bolts/screws... it's only to keep the fabric pressed up against the mounting location)
- Clamps or Clothes Pins
- Scissors, Exacto Knife, Box cutter, Hacksaw, Knife; to cut out the fabric.
( i used a Mastercraft folding utility knife : http://www.canadiantire.ca/AST/browse/6/Tools/HandTools/UtilityKnives/PRD~0575025P/Mastercraft%252B17-Piece%252BFolding%252BUtility%252BKnife%252BSet.jsp?locale=en)
Redishade Temporary window shade is a temporary shade use to cover windows. It comes in Fabric form and Tissue form (for extremely temporary use). It does not contain any mechanism to raise or lower the blind;all it is, is a fabric sheet that has been creased to fold in a zig zag pattern.
In this instructable i am going to be using the fabric type because it will be more durable, and last longer. The tissue paper one might be usefull aswell because you can just throw them out after each use, which would be usefull if you are using coolant or other solutions and would want to dispose it easily... but then again, the fabric one can be washed to take out the chemicals. It's your choice ofcourse. I noticed that the fabric version was only a dollar or two more than the tissue, so you might aswell splurg for the fabric.
The window shade is a zig zag pattern of folded fabric. It is capable of collapsing alot, while also able to expand; perfect for this use.
Canada Link: I live in Canada but they dont have it posted on the Canadian website.... but the store had the same one as the USA website.

Step 2: Measure Your Strips (Top Cover)
DO NOT MEASURE FROM THE END OF THE WINDOW SHADE, YOU NEED TO HAVE EXTRA FABRIC ON EITHER SIDE;
Read on before you do anything yet.
Next measure an extra 1" on either side; this is to mount the side covers(the window shade that i have has 1" folds. if your shade has 1/2" folds, only measure an extra 1/2" on either side).
Draw a line connecting the bottom row which is 4 1/8" long to the top row which would end 1" outwards. Cut it out and now you should have a piece that looks like this:
Step 3: Cut Out the Edge Peices
Make sure that the angled edge has a flap that will go under the top cover so that the glue will be strong.
See how the top edge of the SIDE peice is NOT a point. It has some extra fabric to go under the top cover to glue them together
In the drawing, the green shape is the SIDE cover, the black dotted line shows the profile of the top cover, and the blue bar is where you are to put the glue, since the flap will attach the side cover to the top cover.
You will want to slice a bit of the fabric (about 1/8") on the SIDE covers so that they will fit properly under the TOP covers. Check the photos.
Step 4: How Many Zig-zags Per Axis
For the x axis, since you are going to be mounting it to the table, you only need 6 bumps: ^^^^^^
But for the y axis, i have 8 bumps: ^^^^^^^^. since there is a longer distance between the mounting spots.
For the z axis, since most of the dust will be falling to the ground and the other axis covers, you only need to have one half of the axis covered; the bottom half (where the dremel or other cutting tool is pointing towards).
Step 5: Glueing
Go to the next step to see how it was done more successfully.
Step 6: Clamping
Step 7: After Finished Drying
This is what it should look like now that it's finished drying.
Step 8: Mounting It to Your Machine
Step1: Drill pilot holes into the front of the mill collumn 1/2" above the Aluminum Channel.
Step2: Use scissors, knife, hole punch, or something sharp, to punch holes into the side of the outer bumps of the axis covers.
Step3(optional):If you want to, you can use the sheet metal, but i dont have any with me so i am just going to spread out the screws, drill holes in the same spot as the mill collumn and axis cover.
Step4: Screw the axis cover to the mill collumn.
Step5: Do the same for mounting the axis cover to the X-Axis plywood base.
Step 9: Finished and Ready for Machining!
Hopefully this was a tollerable instructable; for it was just my first. I hope to provide more later on.
