Xzero Damper Feet

[HuntinDoug]

I have my Viper X2 40 x 60 99% complete. Ive been looking around at places like Granger for machine feet. Nobody seems to carry what I'm looking for in metric. So, I made a set similar to the ones I made for my 60gal compressor. My table is a sturdy wood construction that is mounted to my basement wall. I want to dampen the sound & vibration as much as possible. I was able to find the parts at my local Ace Hardware store. Total cost was less than $15.00...Thought I'd share

Parts:
4 - 1' thick rubber stoppers that taper from 1 5/8" to 2"
4 - M8 x 1.25 flange head bolts approx 1 1/4" long
4 - 5/16" washers 3/4" OD
4 - 5/16" washers 1 1/2" OD
4 - M8 x 1.25 nuts

First I vised up a scrap piece of MDF in the mill, and cut a 1 3/4" hole with a forstner bit.



The taper in the rubber plug fit nice & snug in the hole. Then I cut a 1/2" deep blind hole in the bottom of the plug with a 3/4" forstner bit. The rubber actually cuts smooth, but it heats up the bits fast.



After that I used a 3/8" forstner bit to go the rest of the way through. Put the small washer in the bottom hole, the large washer on the top, and the lock nut to hold together.

Cool setup. Are you planning to let gravity hold the machine to the table? I did that with the first Raptor I got, but found that even with anti friction feet, the machine quickly tried to walk off the table. What I ended up doing, rather than bolt the machine down to the table, was to take a hole saw and cut holes the size of the feet in the middle of small square pieces of 3/4" plywood. I set the feet inside the holes, and screwed the square plywood pieces to the tabletop--essentially making little cups for the feet to fit into. Worked like a champ.

The carpet in the last pic is actually a rubber backed floor mat. When I shove the machine now, it doesn't move. If it does move on me I have a set of 2" square rubber cups designed to put under furniture with casters to keep them stationary. I can screw them down to the table. Or I could drill thru the table and fix the damper feet to the table.

I use hockey pucks instead of rubber stoppers. I epoxy coupling nuts into my wooden frame to accept them.
