    Bowl Coring System - DIY?

    Has anyone here ever made one? I've seen a few videos, and if I had a good welder I think I could make a good one. But, if someone has made one, please post pictures.

    Mark: I've not made one, but I'd guess that the most difficult part would be the knives - probably better to buy them and see if you can weld up a system to hold them securely and that pivots in the right plane.
    I went in the other direction - the MacNaughton system. IMHO it's got a bum rap - it's not that difficult to learn. There's some excellent videos available on YouTube, and an extensive article in the AAW Journal that compares the available systems. I've been using it since I started turning nearly 10 years ago. It was among the first tools I learned to use after learning how to rough out blanks.
    One nice feature is that there are so many people that are afraid of the learning curve that you can (at least you could) pick up a full set of them pretty cheap on the used market.

    I know, OLD Thread, but I have an update. I acquired 4 feet of aluminum square tubing 1.5" x .125" wall, square corners, inside and out. I have fashioned an elow style articulated system, with bronze flange and thrust bearings, on shoulder screw pivots. The original banjo from the G0766 id the anchor point, and I am using 1" diameter steel shaft for the mast. The end effector is a Sorby hollowing tool. I finally got it all together tonight, and tried it out. It works well enough, but the Sorby if too short to meet my deep hollowing needs. Back to the drawing board. I'll post pictures tomorrow night, along with the tool rest mod I had a neighbor weld for me. I have about $60 invested in the articulated system (bearings, set collars, shoulder screws, nylox nuts, etc.) and the Sorby was about $50 (birthday gift card for Woodcraft). I think my next bit is to make a long swan neck from 1/2" square steel, and have a cutter attached to it (similar to Harrison Specialties, with out the fancy nickel plating).

    Mark,
    The thread you have included is one about coring systems not hollowing rigs.
