G-Code, DXF and Printable Templates


These templates can be printed on 8½ by 11 inch paper. All except the tripod_base_overview.pdf are sized on a one to one scale. The tripod_base_overview.pdf shows how the parts fit on a piece of stock.
The scaling can be checked with the dimensions of the bounding boxes on the templates.

The gcode and dxf files work on my systems but they may not be compatible with others.
 

Video Transcript


This video is about a base for a tripod. The length of its arms can be adjusted. This allows it to fit tripods at their lowest and highest positions.
The design is simple and the unit can be cut with basic wood working tools.
This one is CNC cut and can be cut on the 18x24 machine.
The body of this unit uses the same basic profile as the base for the light stand that is shown in the light stand video.
The cut’s maximum depth is 0.55 inch, which allows the code to cut a variety of ½ inch stock. This extra depth means the bit is likely to carve into the table bed, so a sacrificial slab is secured underneath the stock to the bed of the machine.
The parts are cut from one section of ½ inch plywood.
The plywood is cut to 18 x 23 inches and screwed to the table bed. Screws in each corner, and 5 inches from the edges, hold the plywood in place.
The machine is zeroed at the lower left hand corner of the stock, and the cut is run.
After the machine has finished the hold down bridges are cut and the parts are removed.
The parts are sanded and painted and the hardware is installed.

Tee nuts on knobs tighten the arms to the body.
They are on carriage bolts that are pulled into the arms.
5/16 by one inch screws or tap bolts are threaded into holes in the arms. These serve as pins that keep the arms aligned, this makes adjustment easier.
 
The casters can range in size, and all three need to swivel. Larger casters work well on uneven floors and can be used outside.
There is a large hole in the end of each arm that accepts a foot of the tripod.
The feet rest on the top of the casters’ bearing plates.
Spring loaded clips cut from 1/16 by ¾ inch aluminum angle secure the feet to the base’s arms.
The aluminum angle is drilled, cut, and ground to fit around the feet of the tripod.
The angle is also cut for a tab to grip. This makes it easier to move this locking clip.
Springs are attached to the clip to hold the feet. A spring can be installed on the back of the clip to push it into place.
A large outside diameter washer on the clip’s attachment screw helps to securely hold the clip and spring in place.
Alternatively, a coil spring can be attached on the end to pull the clip into place.
Securing the feet of the tripod improves the stability of even an older well worn unit.
It also allows the tripod to be adjusted to positions that would otherwise be off balance, which gives more options for positioning the camera.
This base is sturdy, inexpensive, and makes moving and stabilizing a tripod much easier.

Thanks for watching!
 

Construction Notes

The parts barely fit on 18 x 23 inch stock, so it is important to position the stock accurately.
The spindle of the CNC machine is moved to its extreme lower left position of the machine, which is X0, Y0.

The 18 x 23 inch stock is then attached to the bed with the top of the lower left edge of the corner as 0,0,0.
Check that the machine can move to the extremes of the cut's range of ~18 inches and ~22 inches.
