One is for rough and the other for finishing off smooth, But if that is bugging the life out of you, then why dont you change one to be the same as the other

Most grinders have two different "grit" wheels on them. One for rough grinding and one for "finishing" or smoother surfacing.

Each wheel is a different grade of grit. The left is for quickly removing larger amounts of material, the right one for finishing off. Keep dipping the object in water to keep it cool.

The earliest record of grinding I could find was Blanchard Grinding who Beginning in 1909-1910 in Cambridge, Massachusetts, as one of the original, grinding equipment manufacturers with their original "soap stone" grinding wheel machines,
So the Machine seems a really early model

Comment on How do i get rid of stains caused by metal sparks on porcelain? by Flying Dragon

You could try muriatic acid (the same stuff you use to etch concrete) it may or may not dissolve the metal (might take a while). The trouble is, those metal sparks come off so hot they will sometimes melt right into the glaze of the porcelain.

those are not stains, you burned the clear coat with the sparks, unfortunetly theres nothing you can do, other than some light sand paper to scape it off. the local hardware store sell a speacial saw for those type of bolts, any time you use a die grinder cover things around your work area so you don’t damage things.

You burned the finnish, nothing you can do to clean it.
You can however get some porcelain touch up paint and cover it.
Apply it with the very tip of a toothpick.
Follow the instructions on the package and you should be ok.
You can get the paint at a home improvement or a D.I.Y. store.

Good luck

Comment on Factory-Reconditioned DEWALT D28110R 4-1/2-Inch Small Angle Grinder by J. Wayland Eheart

The grinding wheel that comes with it has a 7/8″ arbor hole, but the grinder arbor is 5/8.” There is a backing plate with a raised portion to enable acceptance of 7/8″ wheels. However, THREADED 7/8″ accessories won’t work. I bought mine for wood carving with a Lancelot, which has a 5/8″ arbor hole, which is very thick, and which required me to pull off the backing plate. Said plate is hard to remove (very tight fit; requires pliers) and first-time users might not even know that it is removable.

I’ll write more later; just thought I should get this on the record in case someone needs to know, as it’s not explained well in the manual. I’ve only had this thing a short time; so far, so good. No reason not to give it 5 stars if it pans out.

Comment on How do I cut through a concrete wall with wire/steel running through it? by Peter W

You should do a core-cut. The least damage to the concrete will be done that way and you can control the location and size of the cut most easily.

But, if this is a post-tensioned or pre-tensioned structure (rather than pre-cast or cast-in-place), then you will not want to cut any "tendons" (rather than rebar) as you will weaken the wall structure. The chances are slim that you have to worry about tendons – but if you do, the consequences of cutting them without planning can be nasty. You may need to check with the Manager or builder to know what kind of system was used.
