Whatever you make a good guard covering 60% of the wheel helps, especially a big wheel, I was unfortunate enough to have a mate killed by an exploding 16" wheel, The guard was too flimsy so a big chunk went through it and took the side of his head off, I had never seen a dead body before so it stays with me, we were outside the workshop smoking not 5 mins before, next thing I know everyone was covered in blood and brains, I suddenly found a new respect for machines.
Grinding wheel guards do have to have proportionate beef. Sheet metal is adequate for a 6 x 1/2 wheel but a 40 lb grinding wheel running at 1500 RPM requires major containment.
Back in the day I gave up on the maintenence shop's priority list and replaced the motor bearings on a 16" Hammond pedestal grinder central to roughing of HSS tools in the heavy tool section. Ham said the bearings sounded like a "si-reen fiulla rocks". The malleable iron guards were attached with four 1/2 bolts but the castings were hefty loads to handle for the then-muscular yours truely. The bearing swap went ABC but this is about the guards.
You can bet those Hammond guards could contain tbe burst of a new wheel. One had done so in the past: the scratches and grooves were still there graven in the casting.
On big grinders like this there are "tongue guards", heavy steel bars mounted to adjust radially on the guard upper and lower. These are designed to close the gap between wheel and guard. Gotta keep adjusting them the wheel wears. It's all part of the containment.

Check this site there may be a arbor for you. I would just make one.
For the price, if the quality is decent (USA made it says), hard to beat these...
Then all you need to do is make a base.
I saw that but need much larger diameter shaft and threaded. Thanks
