Yep! I am building a heavy duty copy stand using cold rolled steel and I thought some readers might like to see the work in progress. I am using a piece of 1" cold rolled steel for the vertical and the other parts are also being machined from cold rolled steel. Please click on the following link to see the parts: http://www.flickr.com/ As I indicated the vertical rod is a 1" piece of shafting material I picked up at the local foundry. It is very heavy and very sturdy.
You will also see the bottom flange that has been machined. It will be bolted to the copy stand surface. I have two set screws in this piece to make it even more sturdy. In another photograph you will see the sliding sleeve that will be used to raise and lower the camera. I can feel no "play" in the sleeve at all. It is machined to 0003. tolerance. I think that is the way I am supposed to write 3/thousandths.
I will have a vertical arm attached to this piece and it will be used to hold the camera. I will be replacing the hex-head bolt with the thumb bolt. I am considering a few different ways to attach the camera but I think I have pretty much settled on one device. I will share photos of the finished product. Thank you for viewing and if you have questions, I will be happy to answer.. God Bless.. Jerry..
