Is a variable speed grinder essential?

Re: Is a variable speed grinder essential?

If you are are using crushed glass bottles etc., you will not end up with flat edges to apply to the bands. Again, I used broken colored glass window panes. Maybe, you can find some that is a similar colored to what you plan to seed the top. They may not be a perfect match, but maybe an accent or complimentory color. If you add any aggregate larger than sand, that will make a big difference in the look also.

The only way I'll get my hands on stained glass is by visiting the local church at night with a brick
I was considering filling most of the form except the edges and then making up a mix with a high density of crushed glass for the edges in the hope that most of it would stay there! Sound like a plan?
I'm also going to make up a sample with gravel and see how the aggregate comes through when polished....so far Ive only made sand cement samples and not polished them, just to get and idea for the colour

Will 4" pads fit on a 9" grinder ok or do I need to pick up a small grinder?
Thanks

C'mon now that's just silly. Get pads that fit the grinder/ polisher.

The bands/edges don't have to be a perfect match for the surface. They can be "contrasting" and still look great!. As far as preseeding the edges is conserned, that is up to you. What ever you come up with will be just fine .

Thanks again guys!

One more question before I buy guys.
I'm buying these discs ATS Premium Wet Diamond Polishing pads discs 100mm (4") Granite Marble Concrete Terrazzo 9 piece set: Amazon.co.uk: DIY & Tools
Should I buy a rigid backer pad:

or a flexible backer pad

Also, is the M14 the standard fitting size for angle grinders?

Thanks

You should get a rigid backer, since you are seeding your form with aggregate. But backers are pretty cheap... Why not get them both.

I wanted to post this in case anyone want to polish material but doesnt have a variable speed grinder.
