Hi VDG'ers,How do you guys make holes in your bowls? I've made a number of VDGs over the years using various approaches but the problem I always have is making a hole in the top dome. There are some alternative approaches that don't require the top roller to actually be inside the sphere, but I prefer my column to extend up into the top sphere. For my next VDG I'm planning on using a stainless steel garden gazing globe. I have one that's about 40cm in diameter and can get them up to 100cm in diameter. It's very thin stainless steel I believe but stainless is really difficult to cut through cleanly. I was considering trying a plasma cutter to do it. Any thoughts on how that might work or other suggestions?
Thanks, Troy. On 21/02/18 22:15, Matthew Sweeney wrote:
A local bakery had some they were going to upgrade, I need to get back to them to see if they will still consider selling me the old ones. For now I use the standard 14" 'banda blanks' from IKEA.
