Woodstock feet replacements? - Michael Meyer - 10-07-2009

Now that my Woodstocks are getting older, the feet are getting to the point that just "sanding" them isn't working... as with the drive wheels, they're turning into sticky goo.

I have had no problem finding the tan rubber in furniture feet, but cutting them into little Woodstock feet is turning out to be more difficult than I expected. They end up the wrong size, the wrong angles (the rubber deforms when pressed on with a knife), etc.

Any ideas on how to cut uniform replacements?

It may be helpful keeping the rubber in a freezer overnight. It probably won't deform when you cut it due to its frozen state.

I never tried that on my own, the idea spontaneously came to my mind, so it might not work.

Good luck.

Thanks. I knew somebody had to have SOME ideas. I thought of cutting razor blades to build a box die cutter, but I've never done something like this. The feet have to have depth and a taper unless they are glued towards the surface, but that would change the way you access the screws. I guess another approach would be to fill the openings with another material and just top them off with the rubber part. Still... a replacement piece would be best.

maybe a mold to fill with hot glue, topped by rubber?

Hi, Doc; are you OK?

I read your post and wondered about it since; no ideas so far. The specific format of the rubber feet actually helps cutting a spare from raw material (they are like small bricks). And the mold with hot glue seems valid: just wrap an existing feet with any aluminum foil (thicker than the one used in the kitchen, which is as thin as a paper) and remove the feet from the top: your mold is ready. You could also try to carve the glue bar directly and then use a small amount of hot glue to set the sheet rubber feet (flat cut) in place. I would also suggest to cut the new rubber feet (sheet) a bit larger than the actual feet so its edges match the thickness of the small borders around them in the calculator case. Wish I had a picture or a Chinese to write down its description in a thousand words...

Success!

The idea of Luiz how to build a simple mold is great, however, instead of hot glue I would prefer a 2K-silicon compound, which certainly can be blended with a filler and/or tan pigment to get the right hardness and surface. Such silicon compounds are usually available at modelling shops or dental supplies.

Hi, Luiz, and let me add my belated welcome upon your return from hiatus!

I admit to not quite getting the reference, there -- does this refer to a calligrapher painstakingly producing an illustration 'worth a thousand words'?

Hi, Karl;

Yeap, you are correct about the 'chinese thought'. It was just a reference of the origin of the thought (at least, I've been told that since I was a kid...) because after reading what I wrote, I felt as using too much words and failing to describe it... Frustrating.

Cheers and thanks for your welcome. I appreciate.
