Lattice Lamp custom fixture

Instructions

Use the 01_fixture_cutting_file.svg to cut the fixture in your 20mm thick, using the horizontal shelf. IMPORTANT: all the files use the same reference origin, so for the first file, probe your SO in order to have the reference on the upper left corner (first probe on the top right, second on the top left, and third probe on the left hand side (supposing that your piece of MDF is perfectly square on that corner! - make sure of that). Adjust the offset on your cuts to make sure that your Lattice Lamp parts fit tight, but not too much - you don't want to destroy your fixture to fit or remove your parts! WARNING: you must use 10mm depth for the final cut (if you use another value, the reference anchor of the 02 and 03 files will be wrong!) Switch your Workstation to vertical mode. Install your fixture, your 8 parts, and clamp them firmly against the vertical clamping face. Create a new grid, with two points on each side of the parts, against your fixture, and the third against the left hand edge (see pictures). Import the 02_tenon_cut_file.svg, cut your tenons on the first side of your parts. Then flip them upside down, and cut the tenons on the other side. WARNING: to make sure that you cut to the right depth, make small passes above your parts until you can see the trace of your bit on the top (0.1mm increment). I had a 0.5mm offset in my case. So you add this offset to your final depths afterwards. Place your 4 other parts (if you make cubic lamps as I do, with all parts 200mm long! otherwise you will need a second fixture with longer slots) Import the 03_cross_cut_file.svg and cut your crosses on each end of the parts. Switch your SO to Horizontal mode with the shelf. Attach your fixture in horizontal position (I used two screws). Make a new workspace and grid as indicated on the picture. Place the 04_horizontal_cuts_template.svg file. You will now be able to cut the recesses on the 8 parts at once. I drew one horizontal rectangle, 231mm long / 7mm high, and placed it at 7mm from the top / 80mm from the left. Again you may want to test first with very light passes that you are at the right location. You may have to adjust the y position of your rectangle to be exactly where you want (i.e. right in the middle of your tenon - use the crosses you just made to test the alignment). Then cut your 8 recesses on the first end. Flip your parts, cut the recesses on the second end. You're done for these ones! You can now place the 4 vertical parts to cut the grooves for the panels. Again, you will draw a rectangle to your dimensions (7mm wide / 158mm high) and place it at x=87/y=21, copy it and add 30mm in x, again with 60mm and again with 90mm. You shall have your 4 grooves ready to cut. Check the positions with the guides. Finish your parts turning your stocks by 1/4 turn on one side, and cut the second grooves. That's all! For my first try, I could take the whole cutting process for the 12 parts down to 1h30-2h00 max. Hope you'll find this useful. David
