Build instructions for DIY BO screen?

I tried in vain to find the thread where this fellow had pics and instructions

to build a frame.


From memory - he used 2 1x4 (cut to desired length..) for the top

and bottom and 3 1x4 butt joints between for ends and center.


Metal T's for center joints and L's for the corners. He then used

small trim molding to edge the front (to raise the BO cloth) and

stretched and stapled the cloth to the rear of the frame.


The whole thing looked a bit heavy but the indicated that it was

very sturdy and resistant to warping.


There are detailed instructions to be found, but I can't find them either.


Good luck with it.

Never mind - Gambit found 'um - the 2nd one looks nice...

Thanks for the links and suggestions, everyone. I used the suggestions as a starting point, and made a few enhancements (at least in my mind).


One thing that worked out well for me was using primed MDF 1x4's for the frame. I went this direction because the MDF is very straight and true, as opposed to 1x4 wood.


I also used Simpson Strong Tie joining plates, instead of 'L' brackets. It's overkill, but the ties are cheap enough at about $0.20 each, and have 5 screw holes for each attachment side. Ensures no lateral racking whatsoever! Also allows using a simple butt joint instead of mitered corner.


Used two equally spaced vertical intermediate braces inside the frame perimeter to ensure the horizontal frame pieces didn't deflect at all under the fabric tension load.


For the velveteen mask border used 1x3 MDF with 45 degree mitered corners. The MDF really shines here, because the edges are pre-rounded and perfectly straight. If you staple the heck out of the velveteen on the backside of the MDF, you get a really tight, straight masking edge around the screen (actually looks better than the velvet wrap on a Firehawk that I saw in a HT store).


If anyone would like to see screen shots of the construction, I'll try to post some pics.


Thanks again for all the help!
