i'm based in Stirling, just down the road. Can we organise a McMoonter open day where we come and gas about with cool stuff at your place? I can bring chainsaws 😈
nice work. did it take long?
A couple of minutes per side. It did consume the discs though. 5mm is thick plate. I was surprised just how heavy each cut out was.
The narrow 2mm discs are too thin for my grinder centre to clamp down onto. I used a second partially worn disc to bulk it out. I used each disc until it matched the packer's circumference. I'll try and find a big washer instead to complete the job and use up the part worn discs.
Open day? Well, the garden will be open this summer. Watch this space, it could be special. Diamond geezer possible visit.
Often grinder disc center "nut" is flipable, when using thin discs have the raised center on the out side the flat side should clamp the disc good and tight.
^ what itstig says is what mine does.
My grinder is pretty retro, probably early nineties. My pegged lock washer is flat on one side and has the stepped centre on the other. I could flip it, but I'd need the stepped centre to centralise the disc. I think a big washer under the disc will do it, its only a mm or more I need to take up the slack.
Cereal box cardboard 1 or 2 layers are ok substitutes for washers and the disc doesn't slip
