Increase Your Projected Image

Has anybody combined a single lense form an OHP and attached it to a triplet or copy lense? I experimented with this setup and found that I increased my projected image at least 2 times without image degradatation.

I don't know if this idea is well known, but is sure makes a difference if you live in a small place and dont have enough room to project a large image. I would be stuck with a projected image size of around 40" to 50" (not too sure, didnt measure without ohp lense), but with OHP lense attachment, I'm gettting a projected image of 75"

It works! So if this is old news, forgive me and ignore this, but if not!

Have fun!
