The long slow tripod build

Recommended Posts

I wanted a nice tripod as a gun rest and for occasional camerawork.  I settled on the big heavy studio type they are better for cameras as they dampen vibrations and for a gun rest it'll be great because of the same thing - - mass.  I won't be hiking anywhere with this thing.

The wood is Maple I harvested on the property. The steel is a plate I got in the fleabay, some extra heavy steel gas pipe and various A-36 grade crud steel from Hillman I got at the BORG.

The knobs are blanks from Carr Lane that I drilled and tapped.

Ii is only mostly done.  The angle head and gun rest are not even designed yet. I have some fill work and paint to apply, Plus I need to create the locking clamp for the head and gun rest that will slide up and down in the steel pipe/tube. I'll use another Carr Lane knob for that. The sanding and applied coatings are yet to be done to the wood too. Also there is the feet to finish. I'm going to turn steel spikes for one end and put rubbers on the other. The inside leg parts will pull out and reverse to invoke the spikes or rubbers.

So far I'm really happy with how it's turned out. The leg angle adjusters work flawlessly and are very robust. The action of the leg extensions is smooth as silk. And it is solid as the Rock of Gibraltar

First I made these three little knuckles. They are part of how the leg angles are set and locked.

The first pieces of 3/8" steel drilled with 1/2" and tapped for 5/16-18 one side and clearance through the other. I made them to be clamps by clamping them together for drilling, Then sanding 0.010" or so off the faces with the hole half then re clamping them on the 1/2" shafting and welding one end. This way when I engage the tapped hole on the end opposite the welds they would squeeze around one of the shafts locking the action.

Then I welded up six of these below clamps for the sliding legs

IMAG0280_zps0a665a61.jpg In the pic above you can see the one with the knob has a little flat piece of steel inside the box. That is to spread the pressure of the clamp screw across the wood to prevent damage.

In the pictures of the tripod you only see three of these but there are six that will be on it in the final assembly.

Then I turned three of these 2' maple shafts

Of course this is not the final shape.  I had to rip them and pop them in my planer to make them skinny. like so:

IMAG0272_zpsad3c15bb.jpgThe  above is two halves re-glued together.

I left a little lip at the end to fasten a block of wood. Here is the planer rig = pretty basic. It was necessary that they be very accurate in dimension and each be exactly the same as the other half.

I would have to rip the glue up twice more so I glued them offset like so:

And then mount little blocks to them to keep them stable and flat on my table saw

To finally get this shape (see the piece in the center)IMAG02781_zpsd116a586.jpg

Here are some of the tripod's leg angle locks

The leg height adjusts so smoothly
