Red Gum Burl Hollow Form
I recently embarked on a journey with hollowed vessels and here is my latest.
The piece for this vessel was a block cut from a 90kg Red Gum Burl. The burl was dry when I got it and measured approximately 850mm in diameter.
I mounted the block initially with 35mm pin draws in a 40mm hole that I drilled in the top of the burl with a forstner bit.
I roughly shaped the outside and turned a spigot on the bottom. I remounted it and finished shaping the outside. I found that I got tear out even with sharp tools so finished it with a couple of passes from a negative rake scraper prior to sanding.
My initial plan was to remove the natural edge but decided midway to keep it and use it as a feature. I took great care in turning the lip down nice an thin and was stoked that it stayed together. This was short lived when a piece snapping off during hollowing - from compressed air . This was later successfully re-glued with the advice of Neil (Dai Sensai)
I wanted to hollow it out to an even 5mm. Midway this plan turned into approximately 5mm for the top half and 10-12mm for the lower half. It started making unhealthy noises and I had visions of it exploding and me wearing the pieces .
Following hollowing I remounted the piece with pressure from the tail stock to shape the foot.
I finished it with 3 coast of Kunos Oil.
Many thanks to Neil (Dai Sensai) who gave advice and took the attached photo's.
Comments and constructive criticism welcome.
Lesson's that I learnt
- Importance of sharp tools
- finishing with a negative rake scraper reduces tear out and sanding time
- I am not totally happy with the final shape and will take more care next time during shaping
- I have been given the advice to wrap vessels with voids etc. in tape to assist with holding it together during hollowing - I will certainly be doing this next time.
Finished dimensions are approx 220mm diameter and 210mm high.
Thanks for looking. Comments welcome!

Another hollow form addict in the brew eh! Although the final shape might not be 'classical', it certainly doesn't look that bad either Nice work I reckon

Well done.
If you do wrap, use sellotape or brown packing tape as they don't stretch as readily as eg duct tape - a tip.Cheers, Ern
