JD, paging JD, ... you're wanted back in your thread (before the 'tard takes over )
Wow...biffo that was nothing to do with me!

hahaha...

I usually wait til' i've got new pics before I respond, but I dislocated my shoulder again on Friday, out surfing - my secoond lil' trip n an ambulance, so I've slowed down on the work front...but not for long!

I actually buy into Beery's attitude to twin-fins. Prettymuch everything fin-wise is a variant on either a single or a twin. When you move quad rear fins up closer to the front pair, you get progressively twin-fin-like characteristics. If you move them back and closer to the centre-line you get more thruster-like.

And then with thrusters clustered close, you get single-fin-ish.

With Matty's board, the front pair is further back than for a thruster, and the fins will be larger than standard. Literally as if to save on the tedium of excessive numbers of plugs that quad/fives mean.

Also the flex of those big swallow sides - keep it clear from the obstruction of a quad rear pair.

I'm enjoying mine, purely twin-fin, but despite the long straight rail line through the tail, I get some of what aeronautics calls "Yaw" - that'd be like having the rudder in an aeroplane too far up - the plane will face diagonally to the direction it's flying, with nothing pinning the tail to follow the nose.

This is the drifty feel twins are both notorious and well-loved for. I once loved that feel, but as a big guy and not getting younger, I like less of that. I think of my board, the Baumgartner some way back in the thread, as a "Dual-single".

The stabiliser on the Frankenboard would be for giving just a little of the central directive influence of a tail fin behind the back foot. This is what I also did with Dolf's Gizmo - his initial reports were a bit of a worry - though he stated it was blindingly fast, it was'nt giving him the joy in the looseness dept, so and I've decided Matt's will have less of the Tomo no-toe-in or cant story. Dolf tells me the Gizmo has grown on him with some more conventional sized fins.

In fairness, I don't really surf big or heavy waves, so I can get away with slippy slide out of control. My first keel fish had thin fibreglass glass on sides, and a small centre fin box. The only time I used a centre fin was a small keel, maybe 2" x 1", and only when I surfed that board at a river mouth type break, which is always hollow and fast breaking. Front side it kind of robbed it of some looseness, though it provided "feedback" and a bit of precision. On the backhand in hollow waves, it really helped with "accuracy" if that makes sense?.

And for quads, as a twin fin fan, I like em close together on the rail, big in front, small in the back, single foiled both. Probably part of the reason I enjoyed the sweet potato. Basically a split keel fin, on the rail.

I acquired a wide tailed, what I would call more traditional planshaped, Tolhurst quad fish as a bit of a domestic traveller to comply if you will with Jetstar.

Quite a rail-based fin set-up with the board… came issued with MR fronts, M3 (centres) on the rear. No provision for a centre fin and being a Tuflite, not something easy to change.

Nice enough board but found it a bit skitterish in some circumstances so have replaced the rears with FCS Nexus - Large, which whilst being quite sizable are quite an upright fin. Problem resolved, seemingly without any compromise to maneuverability.

On another note, must say not only is the quality of JD's workmanship as good as they appear in the photos, the packaging for transport is first class.

Let me loose with a box cutter… :shock:

Of course, J-Lo, did you sense me passing on Monday as I headed back down to Sydney? I really don't know where I reside these days.

'Jaunt' I hear you say… of course, back to where this phase of my life commenced a year ago this October. On a silver bird Monday. :-D-:

Might have to darken your doorstep next drive up to the Sunshine Coast.

Ric, ric! Careful! On one of mine I got too impatient and in my haste scored right through the outer skin in one spot. Scissors are much safer. Or an electric rotary cutter like my Bosch Xeo.
L-mate… safe hands and unscathed, plenty of knife experience and a few scars to prove it. :-D-:

A certain ex-colleague of mine used to claim - "I always just wrapped them in a piece of bubble-wrap, that way the freight people could see they are fragile."

I never went with that call. Really, no really, I can't figure out why I don't trust it!

Anyway fins...If these suckers were easy to make, it'd be a day-job, but with the million plastic pop-outs available, these are the hen's teeth...

Composites, yes...it's a fancy way to say a combination of different materials to gain the benefits of each. Wood alone does'nt cope as a tab material, so there's solid glass inserted there.

Nice josh. Which is more of a pain, glass ons, or tabbed fins??. I made a few fibreglass fins. Funking annoying messy pain in the arse IMHO, but I never had the balls to try glassing fins on. Just seemed like a massive pain in the arse compared to boxes/ plugs

Beery - glass-ons were all there was once. We had a choice of big or small fins. If you did'nt like it, you could grind them off and do it again yourself.

Fins for glass-on are far easier to make - no need for tabs - especially for the likes of those there wooden ones - no need for a tab material insert.

Plugs and glass-on are just about the same installation wise, but plugs are way easier to sand.

Like - there you are sanding the nice bottom of a board when you come across these dirty great lump things you have to sand around.

Record I know of by a sander for most glass-on boards sanded in a day - 6.

Boards sanded with fin systems - 17. (The guy nearly died, but hey...)

It's been scientifically proven that pinstripes make a board go 56% faster! The Locomotive, for Bill in Manyana - 9'x 22...

Nice longboard josh. I can't get my head around a longboard without a "proper" centre fin. I figure it's such a big board I just stick to one fin. Personal preference I know but a smaller centre fin and side bites still feels stiff compared to a single centre fin. They' obviously work as I see a few getting around.

Been using huies 7 1/2" greenough flex in my 9'1" round pin. I thought it'd slip out but it never does. Flies but turns very well.
