I had today off and so I spent some time fabricating and assembling the pc's. With most of the rig welded up and ready it left me with 2 areas that were for me the hardest to deal with - The cutter tip attachment and the Adapter to hold the goose neck in the rig.
Tool Tip Holder - I made a flat spot on the tip of the goose neck (almost 1/2 down on it) and drilled and tapped it. Then took a series of washers and welded them together - then drilled a hole in the middle a bit bigger to accept a 1/4" bolt - then cut a channel in the outter part of the washers - added a smaller washer to the top and put the bolt thru to hold it in place. By making the cutting tip holder this way I am able to change the angle of the cut.
Of course the Monster Articulated Rig has this same set up which is where I got the idea but I used stacked and welded washer to create the thickness I wanted.
The Adapter - Which was a much bigger pain in the rear to figure out and make. The Tube steel of the rig is 1 1/4 and a 1" solid bar fit in snug (not sure of the wall thickness - I just slipped the one in the other when I was out buying the steel ). At first I just bored a 3/4" hole about 3/4 way down into it but later realized that it would be better to just make a large collet with set screws in it. Yesterday I took it to a friend that has a Leblond lathe and he bored a hole all the way thru it just slightly bigger than 3/4" and used a pc of 3/4" cold rolled to ensure a snug easy fit thru. This allowed me to have the goose neck tool longer than normal because it will slip right thru into the 1 1/4 frame.
I know the above sounds easy enough but it took me awhile to figure out how to do it so that everything fits snug and will tighten up securely.
Laser assembly -started on it but not finished as i have to wire it and test it to see if it will be stable enough the way I made it. The pain here was waiting 2 weeks or more for the lasers - didnt realize they ship from Tiwan..........ahhhh well there here and thats the final phase and testing it
