Looks like a fun project.

Is this for your Tsekoa II?
How is that build coming along?

The teskoa build is stalled, I am trying to make heads or tails out of the plans I have, and getting info on hardware needed.

your right

Lucky for me I use to rebuild those photo copiers and have a hand full.
I have collected a lot of stuff from those days.

Corona wipers- did they come with a lead screw? I have an app for something like that... was just planning on using some "found" gear motor and splicing some thread rod to it...

Related Q: Is there some place where old office equipment goes to die, where one can scavenge neat hardware?

copier parts

mmmm
I got the image for the motor off the web from a robotics site. Solarbotics My copier parts are in storage back at my Mom's untill I need them. I can not remember if I kept any lead screws. My stuff came from Canon NP series copiers. I found this site for copier / printer parts.precisionroller
I need to get back to my Mom's soon, I will check for lead screws. I think I have a couple paper tray lift motors for main drive motors if not I might be able to get some from RV slide out drives or jacks.

Cad drawing on the cheap

I use Google Sketchup
It is free and semi easy to learn, but it takes time.

Servocity has nice stuff but their linear actuators will not fit my application
too bad they do not have a worm drive application.

Hiab 360 update

I think I have finished the drawings, so now I need to figure out what to make it out of. For a 1/16th scale model it will stand just over 36 inches fully extended. The crane is made of rectangular tubes. The smallest tube 16mm x 10mm out side dimension, the next 20mm x 14mm, 24mm x 18mm, 28mm x 22mm. I figure the wall of the tubes should be 2mm thick.

I do my best work in brass but I think this might make the crane too heavy when done. Any ideas of what to use

How about a combination of brass and carbon fiber.
Not sure of the scales but you could use something like arrow shafts for the booms etc....

Which version of Sketchup or Pro?
I've downloaded it and starting to look at it.

I need to make or use square tubes there all about a foot long x the measurements given. I use the free version of google sketchup 6. I could make the tubes out of anything hollow then the joints and things out of brass.

Tubes I would say thats true. The tubes are mostly dust covers for the gears anyway. You might want to make the base out of a little brass and some lead. How were you planning to attach it to a base? Bolts? Are you planning on picking up anything with it? Just how functional do you want it. I think it would be nice to be able to pick up a scale crab pot.

Im about way through the videos on Sketchup. Definitely having to think a little different. So far a fun program.

I do all my work with silver solder a lot stronger than tin solder. I plan to make it work like the real thing except that it will only rotate 359 degrees instead of 360. You will notice the center of the base is a tube. the slewing drive tube passes through the deck, crane base(tower) and then connectes to the slewing drive ring, which the crane platform sits on. That slewing ring is connected to the crane base with 36 bolts. These questions have brought new things to light.

When you get to actually building, please add a build log.
Might be fun to try and scale one to 1/32 to put on a boat.

I did a quick search for "Sketchup" on Google. Looks like some interesting stuff has been done with this program.
