I got myself a Paashe D500S compressor with a regulator and dryer a couple of months ago and have been using it with no serious issues. However, after I have been using it a while, if I’m not pushing the trigger on my air brush (Paashe VL) the compressor will start vibrating and moving around my bench like it is possessed. I have the regulator set to about 21psi. The compressor is now sitting on an old towel because the rubber feet on the bottom leave marks in the path that it decides to travel on my bench top.
I know that the rubber feet are primarily used for noise reduction, but is there a way that I can mount this on a stand of some sort that will be able to aborb the vibration of the piston? Or am I over thinking this and need to reduce my regulator pressure?
I doubt it would be hard to make some sort of stand, just remove some bolts and drill out hte stand where you want it to sit and then replace the bolts with longer ones. You might try to get a piece of foam pipe insulation and cut it in half, and sit the compressor on that and see if it helps. The stuff is probably over an inch thick, and its pretty durable! You should be able to pick it up at any Lowes or Home Depot store. Good luck!
If you decide to make a base, look up a piece of hardware called a “lord mount.” It’s a rubberized isolation mount used in aviation to isolate equipment or structures from vibration. You can make a base of plywood, particle board, or even metal if you have the bucks. Mount the compressor to the base using a lord mount on each foot of the compressor, and they will keep the vibration from transmitting to the bench.
My compressor vibrates a lot; I got a pice of 1/4" rubber on which to set it, but that doesn’t help much. I’m thinking of building an isloation base myself, but I’m tired of coming up with projects that divert my spare time away from building models.
My old hobby compressor vibrated so badly I thought it could walk! I used 1" thick dense rubber that I got from a diecutting shop. They used it to protect the diecutting blade from being crushed during the manufacture of corrugate cartons. They were kind enough to punch out 1 1/2" rounds that I drilled through, then used as cheapo “lord” mounts (I never knew what they were called, thanks Bruce!). Worked great to damp out the vibration. Didn’t help with the anemic air pressure so I upgraded to a “garage” style compressor which lives outside in a big box. I don’t care how much it vibrates as out of sight is out of mind!
I mounted my compressor on a piece of plywood using some old car bushing I had kicking around.
The bushings had metal sleeves in them so I couldn’t “over” tighten the rubber donut mounts. The sleeves were only wide enough for the bolt holes and didn’t interefer with the feet of the compressor so the vibration was silenced by the rubber. I used a couple of clamps to hold the plywood to the shelf under my wifes work table. Between the plywood and the shelf I used an old car floormat to help deaden the transmitted vibration. Worked pretty good.
Of course we could have just put it on the carpeted floor LOL.
I have my compressor on a plastic table. It walked badly. Tried the anti-skid matting, but that was no help at all. Tried putting it on the floor, but I didn’t like that. I want to see the gauge with ease. What about furniture cups? They worked for the most part, but it still walked a bit. I know! I have double sided duct (Duck) tape. Furniture cups secured to the table with that. Problem solved. No more walking. Solid solution!
