Finally made a hollowing rig

I lucked out and my neighbor gave me a 20ft long piece of 5/8" solid steel bar. That's what the boring bar, and backrest, and the stabilizer bar are made from. The very base is made from (this was nice) a spike strip that someone put in their driveway back when I used to read power meters around here. It is 1/2" x 3" or so plate, and had 4" x 1/4" spikes welded on them. It got 3 of my tires, and thank goodness that after 10 years I learned to carry a box of plugs with me. 7 plugs later, I finished my route, with the strips in the back of the truck cause NO ONE would have believed that story, haha.

Anyway, so that's the base. The stem of the backrest is adjustable for whatever reason on mine. Just a couple pieces of an old jackstand.

The backrest bars just have a couple of 1/4" bolts, with adjustment nuts on there, for a different boring bar I'm building out of an old weight bench bar at 1" diameter.

The tool holder was from a handle for a drill press, cut in half and ground down. The bit holder was a sliver of the 5/8" bar, rounded off with a slot ground into one side to hold the bit securely (why didn't i just use my sorby tip, duh?)

Tried it out on some sassafras endgrain, and it was wonderful. The control, and complete lack of effort are phenomenal. I should have made one out of wood looong ago had I known that it was this much easier.

Oh yeah, total cost was about 4 bucks, but only cause I bought a couple extra bags of bolts. It now needs to be sanded and all the non metal to metal contact surfaces painted. A little more dressing up some rough edges with the grinder wouldn't hurt either.

Good Job. I felt the same way when I built my first one. You just can't believe how easy and controllable it is while hollowing. No more white Knuckle experiences. Now add a lazer and you will really have fun.

Forgive me for being ignorant and/or clueless but I can't figure out what this thing is or does from the photos. Please someone tell me that I am not alone here.....please....

LE,
Check out this link and look at the hollowing system shown.
https://www.lylejamieson.com/tools/index.asp

It's basically a controllable system for hollowing out vessels with a cutting tip that can safely extend further past the tool rest than a freehand tool.

Here's a link for a utube video on it:

As soon as i run across a cheapo little laser, I'm building it. I already have the design down, thanks to lyle. I used to have to turn my headstock around 180 degrees, and sit on one of those stools with the flip down steps on the bottom, just so I could hold my hollowing tool under my armpit for a 12" or so HF. No more! Thank goodness. That got old quick.
