Wee rubbery bits on rack..

[goatbreath]

The little rubber bits between the glass shelf and the parts the shelf sits on has turned to a sticky mess..
Would you call them small rubber feet,that will do.. :lol:
I feel daft asking,but so much goes wrong you don't think about..
These parts are small but have to take a fair amount of weight is one of the things I am thinking..
Are they sorbothane or just cheap rubber etc
Does anyone have any suggestions that wouldn't cost a fortune as substitutes,
This old metal and steel rack is getting on a bit now...
I very much doubt Apollo the maker has any of them..
Maybe something with a peel off sticky back would work best..
The beams are maybe 17 mm across..

I will obviously have a look myself,but I'm sure someone must have found the ideal thing..
Something that is known to work..
Hopefully it will be available in the U.K.

This looks like the same Model I have here.. :)

Could clear rubber stick on feet do the job? I see them at dollar stores. Maybe your pound stores have similar stuff?

I am looking at these...They come in black or clear...

Yeah looking at the price of sorbothane feet,they probably just used rubber.. :)

I've went for the above in black..I will report back once they arrive..

That looks exactly like what I was thinking. Hope they work out for you. I have to do the same with the glass shelves in a pair of display shelves I intend to display my system on soon.

Finished job about half an hour ago..A bit more time consuming than I thought..
Glad it's done though..
The old rubber was a sticky gooey mess,like road tar..
I used Window Cleaner..The vinegar and water stuff and a few of the 2 sided kichen pads,one side green scrubber,the other side yellow foam ones to get it off the glass....
I let the window cleaner rest on the rubber then used the green side and a rag to clean..
The rubber fills up the green bit,so you need a few..

The old rubber on the painted metal..I used a table knife..Window cleaner..Scrubber..
I couldn't remove it all,So I stuck the feet further inwards..

The smaller size of "wee rubbery bits" would work fine..
It is quite dense material,like hard plastic,but with some resilience...
Hopefully it isn't too hard..
These are tablet shaped rather than domes,so I guess the glass doesn't connect to the rubber in the same way,
so it might let it ring more..

Make sure the metal is really dry before you try to stick the bumpons on..
It sounds obvious..I dried the surface thoroughly with towelling..
I would say wait at least half an hour after that or they won't stick.
It kills their stickiness so you will have to use more..

I had my amp off for 24 hours,so right now things are settling in..
Dynamics are a little less,tonal colour a little less vivid,the bass sounds a bit muddled,
Listening to Kind of Blue,the Bass isn't walking joyfully yet..
That usually happens for about a side and a half on album till the cartridge gets fully compliant..
Plus the amp being off..I swear it sounds better when it has warmed up for a few hours..
That could be my mind playing tricks on me.
I always expect too much out of things..
That piano sounds much better though...

I doubt the type of rubber or denseness would make that much difference..

Two observations..Don't know if it's meant to be the case..
When my system came to life today..
That was after 1 LP,the tonal colour was more vivid..
The Bass and sound in general sounded more open and less restricted..

The differences,my Quad 44/405-2 has been on for 24 hours..

I put my Mission Isoplat under my Quad 44..

Why..??

The Glass shelf rocked just a tiny bit..
It didn't quite sit on all 4 feet at the same time..

Conclusion there,if the rubber was a little more spongy that problem wouldn't have happened..
The weight of the shelf,or even the pre amp too would have caused shelf to settle on all 4,bumpons..
A little softer Rubber would be better for the shelves to sit on..

There must be rubber bumpons that are a bit softer out there..

The fact the old one had decomposed so much they were sticking the shelves to the frame maybe actually had benefits..
AS long as the glass wasn't sitting on the bare metal of the rack itself..

So the Amp being on for a while and the Mission Isoplat seems to have improved things..

Listening to the same test records..

Kind of Blue and Giant steps..

I have got ordered some of these to experiment with..

They may need to be warm a while and have weight on them too. They do tend to settle in. The hardness you encounter may actually make them last longer once they settle in. Could you aim a warm incandescent lamp or a portable heater at them for a short-ish while?

[goatbreath]

They are quite near a gas radiator anyway.. :)

Some rubber feet (not all) does decompose into that sticky mess. I had rubber feet under a PS Audio preamp power supply. The feet decomposed and soaked into the light-coloured carpet it sat on. I was concerned I would loose bond money in the rental we lived in.

Those clear buttons would be suitable for the job. Note that over time they do tend to yellow and become hard.
