grinding abrasives of various grades have to be bought from big city ....I bought abrasives from a powder abrasive shop in Mumbai he was dealer of carborendum universal .......had many grades of carborendum ,aluminium oxide,but he demanded I should buy it in kilos he was reluctant to provide in small amount.
  we have lime water soda ,green glass called float can find 12mm but also 19mm in big citys ........I dont know if anyone here manufactures big disk of borosilicate or pyrex or plate.........
  I had been gifted a 12" pyrex blank from my friend in united states and am grinding it now...it s from newport glass company 
  it could be nice to try casting borosilicate disk may be cellular mirror there are facailities here like CGCRI centre for glass and ceramic reserch institute a government institute but I dont know if they would entertain
  the machine Draper type  costed me around 15000 rupee that might be 1USD=40 rupee(India)
  375 USD
  but in states it might cost more I dont know@ there ...........
  happy ATM

Wood makes an easy base for a turntable. I decided to go
with plate glass, which of course, is very rigid.

I think the list might be interested in hearing about
things like where you obtained parts, as you just sent
me. Everyone would be interested in getting some hint
about how money worked out for this project. Most of
us are from the States and so we think in the same
currency.

So what about things like grinding compounds, etc?

Can you find thick plate glass (19 mm or more) there?
