It has been almost two years of engraving experience till I realize how important a turn table is. GRS turn table seems to be the only one that can be purchased in China, but its price is way way beyond my budget. So the only choice is to make one.
The fundamental idea is to attach a board to a big bearing. They must be very easy to get and work with, and relatively cheap. After many comparisons, I found that the bearing used in Chinese dining table was the best. I assume Chinese restaurants in America use similar tables.
It's the bearing makes the glass rotatable.
The rest was easy. Cut a disc same size as the bearing from plastic board, and glue it to the bearing.
Upside: only costs 6 bucks
Downside: 1. the plastic is not firm enough, shakes along with punching of handpiece 2. cheap bearing not perfectly smooth 3. can't adjust rotating resistance
#1 and #3 of downside are not difficult to fix. The only and deadly problem is not smooth enough. But hey, it's cheap!
