Cast Mold for Replacement Rubberpads for Aerobic Step

This Thing should basically give you an idea how to repair aerobic exercise steppers when the rubber pads have gone or are worn out. Then you run the risk of slipping on the floor, damage your floor, damage your health by accidents.

I have too long looked out for adequate replacements, there were few, but they turned out as too hard, too small, not appropriate. Slipping too much. So I designed my own. I designed an adapter to insert smaller pads, I designed a cast mold and cast my own pads. I cast for 13 steps ith 8 pads each a whole lot of pads, additionally 4 for each which were smaller.

As cast material I used Biresin from Sika (1404 (1 vol. part) and 1434 (2 vol. parts)). The mold was "painted" with liquid wax for antitack purpose. With some experiment the pads turned out very nicely. For best fit I used Ø5mm cylindric dowl pins (better than bolts). I put the mold for casting in a vice, closed moderately.

Best demold is after 24 hours. But honest I was too impatient and demolded after 10-12 hours already, which allowed my a nice pace to produce 16 main pads per day. And 10 medium pads per day.

This should inspire you to build your own pads, the czurrent ones fit for Erhard Sport steps and they work fine!

Good luck!

PS: Sorry for the whole parade of STL-files, didn't want to bore you, but as you may need to design your own pad mold, it hopefully helps you with ideas. And you can progress engineering the wheel, rather than reinventing it.
