Loose Pin Therapy

[Mark Bolsius]

Good to hear from you Roger,

Regarding the climate here in Australia, I live in Canberra which is a
little (about 120 miles) inland on the East Coast. Canberra's climate is as
I have described, but this is not typical for the coastal regions, which go
through almost all the various types you have in North America without
getting quite as cold as you do! So it is equally difficult to generalise
about what the climate will do without being specific in region.

BTW thanks for the pointers on upright pin blocks. I have been aware of the
plugging method for a little while but have not found a piano worth the
effort yet. I usually find that there are so many other problems as well
that to repair everything blows any viability right out of the water.

Hi Mark,
             
Funny about the differences in the climate from Northern Canada and
Australia, However our humidity conditions are similar, 40 below Zero
moisture is hard to find In winter. At the University ( steam heated ) 10%
would be high. In Summer 40 above with 80% RH.
Regards Roger.
