Home made hollowing rig

I made my own hollowing rig and steady rest – it was a pandemic project.  I looked at commercially available rigs and took what I thought were the best parts of each.  It’s a Frankenstein hollowing rig.  It was amazingly simple to make – a few cuts on a horizontal bandsaw, drill holes and a few taps.  It is put together with bolts.  The original plan was to put together with bolts, test it, make sure the geometry was right, make adjustments then weld the pieces together.  Surprisingly, the rig is very stiff, little to no vibration so I didn’t need to weld it.  I think this is a result of the decision to make it out of thicker than needed steel (I am good at over engineering things).  The laser holder needs to be reworked.  But it is good enough for now.  It’s made of 1018 steel and a little bit of aluminum.    The cutting tools are 1018 5/8” round bar with ¼” M42 cutters.  Total cost was about $100.  I also made a sharpening jig to hold the cutters.

Looks great! What is the maximum depth you can go with it?

@kevinbassett  I can go 14".  If I got bed extension, probably 20".

nice! It gets a little crazy way down there around 20” no matter what captive system you go with. John Tisdale does his hollowing a bit different... take a look at Planet Mesquite that’s about 36” in diameter. He has a bit larger hole but the trick is the tool rest which is curves and can fit way down inside the piece so he’s never very far past the support. He also uses a Monroe cutter on a long handle. Check out Ed Mouthrup. He was the pioneer in big vessel deep hollowing. I believe his son and grandson are still active turners. But we lost Ed a few years ago. His work was extraordinary. In our club John Tisdale is the main man for this area of turning. Also, his automotive type finishes are incredible. I’m a bit to impatient for all of that. We are fortunate to have so many skilled and talented turner’s in DAW. Hopefully we’ll get back to live meetings soon. I look forward to seeing you there... bring something for show and tell!
