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.


  1. Hey there!
    Great info on this blog, I have added it to my RSS reader to keep track.
    I have a question on the dimensions you are using. Did you start by checking the minimum or desired focusing distance of your projector? Or did you decide to go the way of using mirrors to accommodate for the necesary focal distance?

    Cheers and keep up the good work!

  2. @Fernando I have determined purely by testing with a "Macro Lens +1 +2 +4 +10" from my old film camera(Acer x1130 and an Optoma TX780) at work and decided on the approximate length. The frame is also able to be extended by only purchasing 4 vertical element to adjust to your needs.

  3. I learned a lot from this post, much appreciated! :)

  4. Very nice, i suggest webmaster can set up a forum, so that we can talk and communicate.

  5. Yes! I would like for the webmaster to set it up too. Webmasteeeer! Webmasteeeer! Guess he does not have time to hear me, let alone to setup a forum and administer it too. Maybe in the near future. ;-) Keep watching...

  6. Great post I must say. Simple but yet interesting. Wonderful work!

  7. Digged google 30 mins, findally i get it, thanks!
