This has nothing to do with dust collection,but still …!
I’m one off those who likes to make his own machinery.I don’t have
anything agains the real good products offered by sever companies and
I’m not saying that the items I make are better,but …I made or
better I chose my motors in this way that with to much resistant the
motor just stops turning.I too made the same mistake (if I may use
the freedom of saying so)of buying motors to powerful.I’ve never had
the bad experience of getting caught by a polishing wheel but if this
would happened,my polishing machine just holds on.Yes,the machine
could me damaged …but I payed something like 10,-US$ for the
thing,so why should I carry about it?
This however,does not mean that I’m not working les save because I
know that this kind of trouble would not happen to me,but I feel much
better and I’m more concentrated to my work.
I’m also aware about the good machinery proffesional people need in
order to keep up with there bussines,but one should make some
thaughts about the equipment he/she wants to buy and the pro’s and
contra’s about it!!
By all means,a polishing machine is made for polishing and not to
take care about a faster procedure of removing material.I believe
that lots of accidents are caused by the time pressure and impatience
of the jeweller himself.
If I may give an advice to those who are accesible for advice,use a
file to remove material and work your way down in the grids.Next step
is the use of sandpaper to remove the small scratches left from the
previous procedure and again step down (read finer grids) in the
number of coursenes.If you need to polish this item,then you will
notice that a slight pressure comes up with a nice an easy polish.
For what its worth it,TAKE YOUR TIME.
