oscillating spindle sander from a massage pillow?!! (and a drill press)

by:Gewinn     2020-02-17
So, we have a massage neck pillow that has never been used, and as a curious person, I take it apart and see what makes it work.
Look, I found a motor and two different sets of gears to turn the knot around your neck.
After knocking off the filling on the pillow and not returning to the original use, the mechanism was placed in my store (
Read as a wholecar garage. . . )
When I think about how to reuse the said mechanism.
Fast forward for a few years, there are a few other videos about making spindle Sanders and me, with a veritable bulb moment --
I can do an oscillating spindle sander with my drill press and the internal organs on the massage pillow!
Material: This building is almost entirely done by using a variety of materials from the old massage neck pillowcase in my shop. wood scraps -
Plywood, month, square tubeMisc, etcalumnum angle1/month.
Bolts, nuts and washersCA (Give me a moment. e. super glue)
And accelerator.

This is a good example of redneck engineering.
If you proceed with this build, you will be at risk of any personal injury or damage to the drill press and/or other equipment.
First of all, I measured the bottom of the column on my drilling machine.
I used two combined squares for accurate measurement.
I put one on one side of the base and then the second on the other side of the base and on the first square.
This will give you a very accurate diameter measurement in this case3/8\".
I cut a piece of plywood into the width of my drilling machine base, about 18 \"long.
Then I drew a 4-
3/8 \"the diameter circle is centered on plywood and centered about 8 from one end \".
I also marked parallel lines from the circle to the end so I could slide around the post.
Cut the shape of the mark and check if it is appropriate.
I marked the center of the slot on the drilling machine base and slotted at the end of the plywood so that I could fix the plywood on the base and use two 1/4 bolts and washers as well as wing nuts
Finally, I made several small wooden blocks that were installed in the same slot of the base and glued to the plywood with CA glue to help align when installing in the future.
I added a piece of wood under the other end of the plywood to support on my workbench.
I found several long screws that fixed the lid on the gear and drilled a slightly oversized hole in the case.
I used the screws long enough to go all the way through the box into a 2x8 part that was placed around and attached the mechanism to it.
My 2x8 is about 15 \"long.
I added another piece of wood on the back of 2x8 so that I could clip this component from the last step onto the plywood base.
I need to extend the shaft from the gear mechanism.
The diameter of this shaft is 13/32 \".
I cut a square tube for about 1-
1/2 \"long, caught in my vise.
The inside of the tube is 3/8 \"wide, so I drill it out with a gradually larger bit until I have a comfortable (but not tight)
Installed on the shaft.
You should be able to shape the tube on the axis of rotation without a lot of swings.
There is already a hole on the shaft on the \"Magic Finger\" so I drilled a matching hole to fix this.
I used a small piece of maple 9 \"long, 3/8\" thick, 1-
1/2 \"wide, drilled a 1/2\" hole in the center. (
For your building, this length should be roughly the same as the diameter of the circle tracked by the handle that operates your drilling machine. )
I then made a square hole with a chisel that fits perfectly with the square tube and then pushes the pipe in with a hammer.
You would want the tube to be Square (
Such as 90 degrees)
Go to Maple as much as possible
I made a pin with a decorative head screw and fixed the square tube on the shaft.
I removed a handle from my drilling machine and will use the 3/8x6 \"Bolt as a replacement.
I drilled a 3/8 hole in a small piece of scrap wood, slid it onto the bolt and fixed it in place with a nut.
I screw the bolts onto the drill press and mark a plumb line on the block with a short height.
Cut wood blocks on this line to create a face.
This is because the \"arm\" of the maple tree is on the same plane as the face of the block.
Use the right drill bit for the taps and screws you will be using, drill holes on the new surface on this piece of wood, and drill near one end of the Maple arm. I used an 8-
Because the bolts on my hand are so big.
Tap the holes on two pieces of wood.
Note: One trick I learned from a woodworking colleague is to squeeze some super glue into the hole after tapping the hole on the wood and let it penetrate into the wood and dry. Then re-tap the holes.
Do this again and you will have a very strong thread on the wood to fix the screws.
Install Maple Leaf arm assembly on the gear shaft (
Don\'t protect it with a pin)
And roughly parallel to the arm on the drilling machine, measure the distance between the two threaded screw holes.
This will be the approximate length of the connecting rod.
You want those two arms.
Gear mechanism and drilling machine)
Parallel when measured.
Cut the aluminum corners into this length.
I used some plastic tubes and I had to make the bushing for the connecting screw of the connecting rod.
For the diameter of the plastic pipe, drill the appropriate size hole at each end of the aluminum corner and slide a small piece into each hole.
Fix them in place with a little CA glue.
Attach the aluminum angle to each arm.
At this point, the gear mechanism bracket should still be clamped on the base.
Use the maple leaf arm on the rotating axis of the hand to test the range of motion between it and the press.
You may need to reposition the gear mechanism for optimal performance.
I made a lot of adjustments to keep this unit aligned and to make the Maple arm the right length for proper range of motion on my press.
Once you are satisfied with this operation, put the pin on the shaft of the gear mechanism and apply some hot glue on it to fix it in the appropriate position.
This will allow easy removal if needed.
Screw the mounting block of the gear mechanism to the end of the seat.
I also removed all the other arms from my drilling machine to prevent any interference when using the Sander.
As you can see in the video, I also made a workbench with a guide for my homemade spindle.
If you have gone so far in this building, I am confident that you can come up with something that will work for you.
