Basically it uses the pressure from the end of a heavy duty wire to hold the component in place. This is probably a very overly complicated way to do it, but it works like a charm.
Step 1: Material List
1) 3/4" x 10" x 20" piece of particle board or plywood
1) 3/4" x 8" x 10" piece of particle board or plywood
2) 3/4" x 4" x 5" pieces of particle board or plywood
8) 1-1/4" pulleys with bearings (with 1/4" hole)
3) 1/4" x 3' steel bar stock
2) 1" x 1" x 6" aluminum angle stock
4) 1/4" x 1" bolts and nuts
8) 1/8" x 1" self tapping screws
4) 1/8" x 3/4" self tapping screws
4) 1/8" x 2" self tapping screw
1) heavy duty wire coat hanger
Step 2: Fabricating the Pieces
Next I cut two of the steel bars to 20" long with a hack saw, and and used the pieces that I cut off to make two more at 12" long. Then I used a file to get rid of the sharp edges.
I drilled three 9/32" holes in each end of the 6" aluminum angle about a half inch apart and a 1/8" hole in each end on the other face. (see pictures for a better understanding)
That's it for the fabrication.
Step 3: Assembly (step 1)
Step 4: Assembly (step 2)
Step 5: Assembly (step 3)
Step 6: Assembly (step 4)
Attach a pulley to the center hole of each corner with the 1/4" x 1" Bolts and nuts.
Set the table with the pulleys on the bars that are running perpendicular to the base. You now have two of the axis's complete.
It should look like these pictures. The other holes are in case you want to adjust the amount of travel.
Step 7: Assembly (step 5)
Drill a 1/8" hole in the long part of the bar about midway down perpendicular to the bend.
Insert the bar into the holes in the end pieces.
Step 8: Assembly (step 6)
Bend a 90 degree "L" shape on the other end with the point facing down. File the end very flat so that it lays flat on the components.
The weight of the steel bar stock handle will be what holds the pressure on the component.
Step 9: How It Works
You can make fine tune adjustments to the exact placement of the component with a small screwdriver or a nail. Solder your component in and admire your handiwork!!!
