Hi Bluesking

Just seen your post here. Well done for joining the forum, doing a design and taking advice!. I wish I had seen this earlier because I would have told you to get the parts water-jet cut which also would have done some of the bigger holes for you and spotted the rest. This is the approach I took on my build and saved me a lot of grief (see build here http://www.mycncuk.com/threads/8206-...Axis-CNC-Build post #10 ) All I had to do was counterbore and thread the extrusions using a spiral tap. I then used a finishing tap to clean the threads or a plug tap where the hole is stopped.

Regards
Michael
