Spacers question.

Post by LeeDerbyshire »

A silly one I know, but here goes. I've replaced the single-sided drive in my 520STFM with the Sony MPF920 (a 2001 model I had with the Sony CXA8061Q chip). I made the cable reach by soldering together some DIL pins and sockets to make an extension (nice and easy, since only one row of pins needs to reach), and I was feeling quite pleased that it all works, but only when I put the cover back on top did I realise that the 'new' drive, being much thinner, is nowhere near the hole in the case.

So, my probably silly question is: how do people generally raise their replacement drives to a position where they'll fit? Is there by any chance a 3D printer pattern for spacers out there? At the moment, I'm just tempted to glue a piece of wood to the bottom of the drive, and screw into that from underneath. I'm sure it'll work, but it doesn't seem right somehow. I don't even know how thick the wood would have to be :-) Or maybe cut some pieces of narrow-bore copper pipe? I'm just hoping that there is a well-known, forehead-slappingly simple, tried and tested way to do it.
