Yep that's all good advice Doug I'll think long and hard before doing anything drastic, many thanks for looking, Jacobs is exactly the same as mine.
I know it's just cosmetic but it does look a bit better now filled though might need a bit more fill. One of the reasons for wanting an infill is so I can reduce the gap between blade and table for straight cuts and I can make any number to suit blade and requirement. I would rarely if ever make angled cuts as I have other machines for that.
Brians' suggestion of hardboard (could use tuffnol or plastic) is good but would cause problems with the fence and mitre guide.
