Interesting project, Wont be a cheap fix tho!. Ive dug out my store
of MOP shell, havnt looked at it for 40 yrs. Had a slight bother
If I recall, it comes from the far east.
Been through the box and there is only one complete shell there. It
measures 7in by 7in. its concave with the depth to the deepest part
of 3/4 in.
The only flat area is where the bivalve had its hinge point. The
inside is the normal iredescent shell The outside is a dark brown
layer of shell some 1/8in thick. Youll have to grind that off. the
smell is awful!.youll need therefore to buy several complete shells,
then get them to a lapidary worker. Hes the only person with a
diamond slitting saw thats accurate enough to cut the thinness you
As and when you get your shells youll find it easiest to cut out the
bits youll need with a bimetal hack saw blade.
Its hard work. So, Where you might get them I dont know. I bought them
from a shell dealer in the East end of London UK.
Polishing it is also hard, tho ordinary metal workers compounds work
ok. ON a new mop only!!
Youll need a polishing machine with 2 to 3 hp running a 6in by 1 in
mop. As for abalone shells these are some 2in deep by 6 by 4in. Ive
lots of small round already cut out in 1/2in and 1in dia. could help
As you may have gathered im in the UK. Where are you? Keep us posted
how you get on.
