Here's how I did mine......Originally Posted by ignatz
Yes, my 'cutting bed' (det'l 04) is a seperate piece to the 'bed support' (det'l 06) and the 'bed support' is bolted through the end frames (det'l 1 & 2) in four places (between the support rails). It was aligned flush with the top of the end frames and clamped into position and then the bolt holes were drilled right through both pieces to ensure correct alignment. The 'cutting bed' was installed after I had the machine up and running so that I could set the 'grooves' parallel to the gantry travel using a DTI. Once the 'cutting bed' was correctly aligned I 'spot drilled' through the ends into the end supports and then removed the 'cutting bed' again. I used three CSK head machine screws at each end between the 'grooves' and 'dry wall' screws in the small outer pieces. The machine screws are going into 'blind nuts' that I installed in the end frames using the 'spotted' marks to establish the correct location. By doing it this way everything can be unbolted if I ever have to replace a leadscrew, A-B nut or if I have to dismantle the machine if I move house.1. Is the assy04 connected to the base support structures? How?
Yes, mine is bolted through the end frames in four places (between the support rails) too. I aligned the bottom of det'l 05 with the bottom of the end frames and then clamped and drilled through both pieces to ensure correct alignment. This was done prior to fitting the upper bed as described above. I also made four 'towers' out of MDF that were glued to the inside corners of the frame structure on det'l 05. The face of the 'towers' had a 'blind nut' inserted and my entire machine sits on four hockey pucks (with a CSK hole in the centre) that are screwed into the 'towers'. These act as vibration dampers and help to keep the noise down (my machine is currently in my living room as I have no workshop to work in at the moment!)2. Are the base supports connected to dtl05? How?
I didn't bother with that but it can be used as a reference point when establishing X/Y/Z zero.3. What is the single wood screw used for?

I really need to update that as I have made some major changes/improvements since then and I am just about ready to start 'real' cutting jobs with it instead of test cuts and tweaks.
Hope the above is useful to you.
