Well I have done quite a few sound installs now, but I too am not fond of milling weights if I don't have to.However, I find that anything but two of the small-sized speakers is just too "pipsqueak" sounding, so I usually go to work on the weights at some point or other.  (In steamers I love to put in two large ovals but there one has more room to work.)The photos below show my P2K SD60 with a Soundtraxx EMD 2nd generation decoder and two small-sized ovals with ready made speaker enclosures from Litchfield Station.  The speakers are the  16 x 35mm because anything bigger is too wide to match the width of the weight inside the shell.They are wired parallel to draw 16 ohms, otherwise they would draw 4 ohms and probably kill the little decode amplifier.Now my precise milling procedure is to completely remove the weight from the loco (you don't want metal bits falling anywhere so you want to be able to completely clean the weight after working on it.  Then I crank it down in my vise and take a hacksaw to it.  I find anything less takes too long.  I finish it off with a big file.  You can see that the hacksaw does a roughish job, but it is done in a few minutes and who knows about my hamhanded technique but me....and now you all.[img]http://i168.photobucket.com/albums/u172/dcrane_2007/SD60ledinserted.jpg[/img] [img]http://i168.photobucket.com/albums/u172/dcrane_2007/SD60weightcutout.jpg[/img]
