    Bang on.

    Yeah I said that resonances were not a concern. I didn't say that they don't exist, but rather that I'm really not concerned about them affecting my sound quality, so I'm not interested in drilling holes like the oyaide has.


    No sense arguing against something I never said.

    I'm not interested in pursuing any argument. I only came here to post a photo.

    The glass also has a lot of force applied to it- in a slight breeze, the large building moves around it and wind blowing against its large surface. My platter conversely is only subject to the energy of 1.8g from my stylus. I would expect that the record itself would absorb most of that energy and then the rubber mat would absorb most of the remaining energy.

    Really, comparing a window pane and a thick steel turntable platter makes no sense. Might as well be asking why a coffee cup resonates for all they have in common

    Its discussion. Ok, your not bothered about resonance, but the whole hifi industry is! Drilling holes in a top plate is a method of dispersing and breaking up resonance. A solid sheet of steel like your mat will amplify it. This will go into your cartridge and produce sub optimal play back. I'm only trying to help, not pick a fight.

    The holes in the Oyaide won't be doing anything much beyond looking funky, they certainly won't be effecting the resonate modes it possesses except in the most minimal sense. Mass does make a difference because it alters the amplitude of the input required to excite it. Note, I'm not espousing the use of high mass, but it's not true to say it doesn't matter either.

    May I ask why Stainless Steel? Why not copper or brass? No doubt the Stainless is durable, and the only reason I ask is because I've seen some high end 'tables with copper plated platters, etc. They claimed that copper was softer, and absorbed more resonance. But of course that's what they claimed, I really don't know.

    holes reduce weight and that will be why they are there

    Pretty happy with the platter. I've still got to give the platter a good polish. It weighs 2.7kg and has no trouble getting it spinning. I've left the brake at the current setting and it only slows it down slightly.

    It lacks the vancy holes of the oyaide, but Oyaide claims that those are to reduce resonance... which I really don't believe is a concern with 2.7kg of solid steel.

    That looks very neat, to my eyes anyway. The Oyaide has a taper so that the LP, supposedly, sits flatter to account for any warps and is designed to be used with the Oyaide record weight. I have used the Oyaide mat on an SL12// and to be honest I preferred the Achromat I am currently using.

    I got this done because a friend was getting some stuff laser cut and asked if I wanted to add to the order. The options were stainless steel, mild steel, aluminium, brushed aluminium.


    Mild steel isn't ideal. My goal was mass, so steel was a better than aluminium. Brass would have been my first choice if it was available, because it looks so damn cool

    Now that I've done a test cut, I might design one with oyaide style holes... purely because it looks kinda cool.It should only take 20 mins in a CAD program, since Oyaide have already done all the hard work designing it

    I saw that. Not a feature that I have to my platter, which is nothing more than a disc of (poorly polished) steel. At $20 it's just a fun experiment. I definitely can't pretend that I've created some audiophile product. Just a shiny heavy disc

    Is that a good idea? Holes hold pockets of air. Air resonates. At what frequency will depend on the hole shape, dimensions and volume. Just a thought.

    Ok, now I don't know what anything is anymore. Holes good, holes bad
