Homemade Grinder Cover ???

Post by kroll » Sat Jun 28, 2014 3:27 pm

Good afternoon guys,well I pickup an old Dayton 8" grinder that is missing the outside covers for the wheels.Finding another set,well I stand a better chance of winning the lotto so I though I would just make some covers out of maybe 16ga or maybe something alittle thicker.Now if the covers would fit being just flat there would be no problem but the 3/4 shaft sticks out bout 1" so like other covers I see there is a dome that allows alittle extra room.I have no equipment for making the dome other than having a torch,heating and stretching the metal but I was wondering if these domes could be purchase pre-made?I know that I could just drill a big enough hole to allow the shaft to fit through but I want it to look nice in the end.Any ideals on a solution or links to a place that sells domes that I could mig weld together.Thanks for any help-----kroll

If it's just the shaft of the nut that sticks out, make a flat cover and drill a hole in it.

And keep your fingers away from it!

A little late reading this but--Why not get a PVC pipe cap extra large enough to cover what you want to. You might make small metal angles, Pop rivet them to the cap and then "screw" the angle to the Flat guard you make. Screwing the Cap to the guard will allow quick removal and access to the nut on the shaft.
This thought is because sometimes you might be able to get to the nut to hold it while you loosen / tighten the Other side for wheel change, adjustment or something or some other problem??

Steel freeze plugs work great for this kind of thing, and come in many sizes...

Just a very short comment? No location where to get the plugs, what are they, Auto or for other type use. How to use / fasten them, reference to another post or What!!

Steel freeze plugs are available at any auto parts store, and come in two main styles, 'standard' and 'cup'. These are the round plugs found on the outside of engine blocks and some cylinder heads (like Fords). One thing to remember, when welding the plugs, strip the zinc coating from the steel, I use muriatic acid to soak them for about 15 minutes, and rinse well with water after. Freeze plugs are also readily available in brass.

Here are some of the cup style freeze plugs, in brass and steel from a small block Chevy rebuild kit. I seem to be out of the standard style ones, they do not have the edge around the outside...

I dapped a sheet of metal for the cup, over a hole in a 2x6. Use the ball of a peen hammer and tap it out to stretch the metal.

Anther solution is to use the cover from the bearings on a trailer hub, and just drill a hole, (trepan in a drill press) and dimple the edge for security. Brazing or silver solder if you like, it works with zinc coating, where welding thin sheet may be problematic.
