has anyone ever modified a tuttle fin into a power box one?
There are so many more t. fins for sail that i thought if i drill and insert a center fixing I might be right. Any advise?
i changed one recently come up a treat i used a select tuttle head cost me $16 including mounting screws.
i ground down the power box with a linisher until a tight fit and filled up any cavitities with epoxy resin (alraldite) before final insertion of fin into box ,drilled the fin to for the mounting bolts, installed bolts and wamo.
A lot cheaper than $200 to buy another one.
Yep, it is possible to do the conversion, I've done more than I care to count.
Would recommend finding someone with a mould and jig for getting the shape right.
we could of swapped fins would have been easier but select make power box and tuttle interchangable heads but only suit there fins.
but you could also go in reverese and grind down a tuttle.
I was wondering about that. I have about 5 tuttlebox fins that I cant use in my new boards & I need a shorter 25cm fin for high wind( think I have a tuttle that size)..sounds a bit complex for someone who hasn't done anything like that before..Any videos or diagrams..?

This shows what you need: http://www.zerogravitydistribution.co.uk/patlove/hardware/finadapters.html
Couldn't find them on the Select or Sunshine Coast Sailboards site (importers for Select). Might be best to give Sunshine a ring on 07 54 913 065 and asking the question, seeing that DKeating (above) used a "Select Tuttle Head" that cost $16.
Hope this helps.
so to confirm this. A tuttle head is larger and can therefore be ground down to fit a power box. alternatley you cut the tuttle head and mould a new power head on top?
" A tuttle head is larger and can therefore be ground down to fit a power box".
Best to use an adaptor as per my previous. Internally, the adaptors are rectangular, so you need to grind the old head to fit the internal dimensions, then glue it in. Externally, the Powerbox head has all sorts of angles on it. For "$16", go the adaptor.
"alternatley you cut the tuttle head and mould a new power head on top?"
Wouldn't think this would have any strength at the join point of fin to (new) head.
Hope this helps.
Just a note on adaptors
Great on G10
do not under any circumstances use them on carbon fins, grinding back the outer layer of carbon weakens them substantially
Further information:
Here is a photo of 2 x types of adaptors.
The top fin uses shows a FinWorks adaptor. Don't know whether these are still made but you might contact this US dealer for info: www.hugedomains.com/domain_profile.cfm?d=foreverflying&e=com
The lower adaptor is unmarked, but may be from Select. These may be available from www.sunshinecoastsailboards.com.au/.
The other adaptors I mentioned earlier in this thread were available from Pat Love, a UK manufacturer. They may only trade with their dealers, in which case you might try buying them from www.surfstore.co.uk/.
Hope this helps.
