Those of your familiar with my previous instructables will remember my sit to stand desk. It's functional, but looks a bit cobbled together and doesn't have the range of motion I'd like. So, I figured it's time to build a better one. I got a lead on some Linak DL11 legs, but no mounting hardware. Time to build something!
Step 1: Design
First, a bit of CAD work in Autodesk Inventor to design the bracket.
Step 2: Materials
A couple of bits from the scrap rack, the laser trick, and some not-so-quick cuts on the horizontal bandsaw later, I've got my raw materials. Update: Unfortunately, for some reason, Menlo Park got rid of the scrap rack. It was a pretty great resource, but oh well.
Step 3: Prepare for Welding
With a bit of tenuous clamping, clean up the ends for welding.
Step 4: Welding
TIG weld the flats and the walls.
Step 5: Drill Frame Mounting Holes
Write a bit of g-code and drill out the hole pattern with the Tormach CNC mill.
Step 6: Clean Up Drilled Holes
Step 7: Prepare for Powdercoating: Sandblasting!
Wanted to complete this project at the Menlo Park TechShop, but the powdercoating oven is broken and has been for a month. Sandblaster barely works either, so if you need either of those, it's off to San Jose. FYI.
Step 8: Powdercoat
A bit of cleaning, a lot of dust, and some cursing at eddy currents in the interior angles and I've got some dusty red brackets.
Step 9: Bake
A bit of cooking...
And a bit of cooling and those dusty brackets are now glossy red. Now, to wait on the legs... fingers drumming. Stay tuned.
And, of course, I made it at the TechShop (Menlo Park and San Jose).
