Air Hammers (cuturi) : any advice??
Bruce Evans
I have found various sites advertising and selling 'cuturi' air hammers.
Does anyone have any thoughts/recommendations/good or bad words about
cuturi?
Does anyone know the compressor capacity required for the cuturi 'A' and
'V' models in cubic feet per minute ( this is how compressors are rated
in the UK)
Does anyone know a UK supplier? (I have found one in Rome who will ship
to the UK - but it would be interesting to know if anyone in the UK can
supply)
Any feedback would be much appreciated.

There is nothing bad you could say about Cuturi,they got the marble and
they got the hammers. Il martello inimitabile che aiuta chi pensa! as they
say. 'A' and 'V' are too small for roughing out though except small stuff
maybe. 'T' is general, 'S' is beefy but useful, 'R' is what I use for
roughing out, but it's big. ('Z' is for quarrymen!) Do be careful of
'Whitefinger'(I've got it so I know).
Yeah, the best co. I know is Harbros. in Bishop Auckland, Co. Durham.
They're excellent. They generally get tools to me by post, next day. Call
them on 01388 605 363 and ask for all their catalogue info., including the
Trow and Holden catalogue (US manufacturer). Harbros stock all Cuturis,
which are the right hammers to be using on marble with a fast beat. Trow and
Holden do fast hammers as well. Harbros are v.good, they import stuff from
all over the place, stuff unnavailable elsewhere in UK. They will answer
queries about required c.f.m for hammers as well. My advise on the
compressor front is not to buy from Harbros because they only stock really
expensive ones. Try a co. called A.P.S in Mitcham: 020 8687 0411. They're
pretty good but very affordable. You're looking at about £400 to get you a
110 ltr 2/3 hp compressor (depending whether 2 or 3 phase. 3 phase is better
and cheaper, less hp needed). I've forgotten exactly how much pressure you
need for the hammers but Harbros will tell you.
Good luck. I love shopping.

Must amend facts previous, I use U, T and S (not R), (I think).
Yeah, remember to post your stuff to the list as well, you'll get more
feedback. White finger is not RSI, which I've had. It's also called
vibration disease. Your fingers go white and numb through bad circulation,
happens in the knuckles as well. Wear anti-vibration gloves and avoid
working in the cold. Some people are more susceptible to it than others. I
don't know many sculptors with it but it's endemnic with banker masons. It's
common now to use German hammers with special sleeves and triggers which
cushion the vibraion. Trow and Holden (US) also make sleeves for their
chisels for the same reason ( both firsts for Harbros in the UK again). It's
a big issue in the Industry, but for the likes of us, we have to look out
for ourselves, there's no one to sue. Be careful, take regular breaks and
avoid wrking in the cold.
The A and V hammers take a standard half inch shank chisel (I think). If
you mean by width the end of the chisel then the smaller the faster. Explain
to Harbros what you're working with and what you're doing and I'm sure
they'll advise you. They're used to dealing with artists, and they're quite
helpful.
Cheers

I'll check out the anti-vibe gloves - I assume Harbos will do them?
Do you know anyone in UK who does the German hammers, or are they not
really for sculpting?
Would it be possible to make some sort of 'holding frame' with layers of
wood and rubber to insulate against the vibration?
Or is this only really a worry if one is going to do lots of long
sessions?
How would you spot that you were getting white finger before it was too
bad - does one get obvious symptoms?
Thanks again for the tips and info.
Bruce.

your hand(s) numb before you developed a chronic problem.
Best advice for injury prevention in almost all situations
is to limit the time you do one activity to no more than 20
minutes. Take a break at that point or switch to another
activity.
