Ball and cup isolation gizzmo's

[Firebottle]

After a suggestion at a recent bake-off of trying a diy version of the ball and cup isolation gizzmo's I have taken up the challenge.

I purchased a cheap set of stainless steel spoons for £1 and two packs of castor cups (small) for £2.
I cut down the castor cups, cut the handles and a little of the 'pointy end' off the spoons and glued them together with some epoxy glue.

The glue cost more than the other bits :doh: I found 3 marbles in the workshop to complete the kit. Finished result:

So this morning I have wedged them under the Lenco:

....and you know what? They flipping well work. Before if I knocked/nudged the equipment stand the stylus would jump, now I can tap away in time to the music on the side of the stand and no jumps :)

Yah hey.

That looks interesting Alan , I might give that a try on my Lenco GL75 :)

Have you lost your marbles :D

Having established the principle, you could use soup spoons, and car body filler, (P45 was it?), to achieve a more 'tarty' job.

I get the idea. Engine dish core plugs might look better than spoons.

Indeed Geoff I think those would look good, however they are under the deck so no real bother.

I went with what was readily available for give away prices, but I'm liking the result :thumbsup:

Cast iron isolation feet seem to be making some headlines nowadays too. The "high carbon" (read -cheapest cast iron) is believed to be the best at vibration isolation. Cast iron plates have been used to isolate factory machinery. There are actual technical reports about the properties of cast iron and the types of cast iron that are used for different applications so it is not audio-myth.
I DIY some cast iron feet for my valve amplifier and it did make a noticeable difference in sound. Cost $16
