Deja-vu
Ok, here is the tools needed and assembly of the frame:
Preferably a quality socket 13mm ratchet driver (Craftsman):
A flat surface (Yes, there was a reason for the Faux Granite stoneware tile and the clean-up of my workbench) Check!
The first two joined together!
It is a little harder than 80/20 Extrusions, because the bolts and nuts travel in a slot cut into the brackets(gussets).
OK! This is starting to look weird?! I think I’ve seen this before. Maybe its Deja-vu.
Does anyone recognize this? Anyone?
Of course there is a reason for all this! If I choose to get parts from JR, they will still be compatible.
As I don’t have access to a full machine shop, I prefer to keep everything store bought with minimal modification.
The dimensions are a little different, but the top build area should be easily adaptable.
It is a strange feeling to see this all done in about a half an hour (excluding the time to stop and take pictures). With any other frame I would have had to fit, mount and measure, and cut, and fit and measure and so on.
I have, on purpose, extended the projector horizontal mount (X axis if you will) travel a lot. It can accommodate a wide range of projectors if I choose to change it at some point.
Bosch-Rexroth Goodies
The aluminium (or aluminum)extrusions and the service from Bosch – Rexroth proved no less than pure perfection! I have received the extrusions cut to size within 0.1mm or better and packaged well. I have received exactly what I ordered, on time (was quoted 3 workdays) in 2 workdays. There were no missing parts, wrong parts or defective parts. Yes, a little expensive, but all worth it when comparing the prospects of finding a welder, cutting, machining, priming, painting, wrong sizes, redo’s etc.
Plastic End caps and Corner Brackets(gussets).
Whoaa! Shiny stuff! Put on your sunglasses before clicking!
