When I was building my base I looked at options for it, sheet of flat steel popped up, quartz, chunk of marble...
Yeah there is quite a list of things that make up a base.... the sheet of steel would have been my first choice, but to get the thickness/size needed would have cost me a child. Sometimes it just isn’t worth the price...
So I opted to cut out a chunk of work surface I had left over from doing the workshop, it’s solid as a rock can’t twist easy given it’s weight and size it’s also easy to drill for additional mounting points if needed. Best of all was free since it was an off cut...
Looking forward to your progress if it ever arrives in a timely fashion!
