L-Bracket for build base

November 29th, 2011 4 comments

Scored some 80/20 L-shape brackets. Finally! Four pieces to be exact.

I bought some M8 bolts too. I can start the Build base tomorrow.

Wish you have a great build day!

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

August 12th, 2011 26 comments

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!

BOM of the extrusions:

#1(one pictured)     9pcs. of 420мм – Extrusion 40х40 L – for the frame and one for the projector

#2,#3,#4,#5      4pcs. of 400мм – Extrusion 40х40 L – for the corners

#6     1pcs. of  320мм – Extrusion 40х40 L – for the VAT crossmember

#7    1pcs. of  305мм – Extrusion 40х40 L – for the Z axis THK KR20

#8,#9    2pcs. of  160мм – Extrusion 40х40 L – for the projector X movement

#10    1pcs. of  105мм – Extrusion 40х40 L – for the VAT tilt LS3-1 mount
