largo Posted February 14, 2016 Share Posted February 14, 2016 I've recently acquired a new 2U rack-mount amp. Problem is my current rack has holes cut on each 1U at positions 1 & 3, so nothing cut in the middle hole (why do people do that). The new 2U amp needs fixed at holes in these middle positions so I wondered if I can just drill new holes? Ideally square, so drill & file to fit the rack bolts, but worst case I'd just drill fit normal bolts to the back. Out of curiosity, I thought there was a thread on flight case builders but can't find it. Any suggestions as if the new amp works out, I might treat myself to new "red" flightcase to match the Vanderkley cabs. Cheers. Quote Link to comment Share on other sites More sharing options...
obbm Posted February 14, 2016 Share Posted February 14, 2016 It should not be a problem as long as you position the holes correctly. If you are not in rush I can send you a copy of the Britsh Standard for rack fixing which has all the dimensions. Quote Link to comment Share on other sites More sharing options...
BigRedX Posted February 14, 2016 Share Posted February 14, 2016 Replace the rack mounting stops with [url=http://www.adamhall.com/en/ah_19_Parts_6162_-_Sliding_Rack_Strip_System_with_rubber_Insert_aluminium_90_U.html]these sliding versions[/url]. Then it doesn't matter where the mounting holes in the equipment is. Quote Link to comment Share on other sites More sharing options...
largo Posted February 14, 2016 Author Share Posted February 14, 2016 Thanks for the replies, I can't replace the strips as I would need to drill out the rivets and then redo them. I don't have that sort of kit, unfortunately. I'm going to try drilling a single hole, punched a guide hole already so keeping my fingers crossed. Unless anyone else has any suggestions. Cheers again for the speedy replies. Quote Link to comment Share on other sites More sharing options...

[/quote] I had a similar situation many years ago with a rack unit, and was able to replace the rivets on the old rack strip with nuts and bolts on the sliding strip - all I needed was a drill and suitable metal bits to drill off the rivet heads and then drill through the new aluminium strip to take the bolts. About 30 minutes work in total and it gave me a lot me flexibility about mounting the gear with regards to spacing for ventilation. Quote Link to comment Share on other sites More sharing options...
mike257 Posted February 29, 2016 Share Posted February 29, 2016 I got my rivet gun for a fiver in Aldi, plenty functional cheap ones about. I honestly think replacing the strip would probably be an easier job than trying to make new square holes in your existing strip. Quote Link to comment Share on other sites More sharing options...
