SHAPER'S HOTSEAT: Larry Allison aka ProBox Larry

I am not fond of the way the forum software inserts new comments in the middle of the thread so I’m trying to post at the end so that the discussion can continue chronologically

WHY and When did a Flang come into play in the surfboard world? I am talking Flang and not Glass over! Ok my friends share in! - See more at: http://www.swaylocks.com/forums/shapers-hotseat-larry-allison-aka-probox-larry?page=3#sthash.DTYsY0wF.dpuf

 

I think it was to increase the surface area and contact area of the box as a means of spreading the load around a little  - even while reducing the mass of the boxes + resin.  

Great answer gdaddy that is correct in the marketing companies words of today and true in product, but in reality what caused the change was roll overs that happend in the mid 80’s with the Official box like shown in this pic. By Official changing his design and added the flang he stopped the roll over effect people were having in a 5 to 6 lb. Clark Foam PU blank in or around 1986 when the first flang Official box came into play.

Yeah, I can see how a (basically) domed bottom on a box might roll over like that.   But anyways, you’re saying the “squared” bottoms of the previous boxes didn’t have that problem, ya?    I know I never had a problem with the traditional 10.5" box rolling over where ALL the load is being leveraged on just the one box by the 10+" fin.  Of course, I’m also not installing those boxes into stringerless 1.5# EPS, either.  

Which circles back around the my previous question about the role of foam density in protecting the box installs  (subtle, huh?)

Lets see photos of you installing with the glass sock. I’m curious if you’re letting the sock extend up thru the gap (above the board bottom). That would be ideal. Sand off excess after resin goes hard. But it seems like a fussy thing to deal with glass sock getting in the way of the tabs. Then you’d risk air voids. 

I’ve been wrapping my boxes with 1" wide glass tape. Two full wraps, then stuff it down in the hole. I use a popsicle stick to poke any glass sticking up, down into the slot gap. Never had a box failure set in 1.35# EPS.

Hi Larry,

         how’s it going?

Oh dear; you may well not like the following questions, if so, I apologise in advance.

I’m currently building some fins for myself, and I’ve already got one surf-buddy who, upon hearing of this, is interested in me building a set of fins for them which they can’t get anymore (they’re no longer in production).

If they turn out well, I wouldn’t be surprised if other surf-buddies start wanting fins from me too; probably something more custom (e.g. same dimensions as the fins they’re currently running but with different flex or maybe a different foil, etc), but irregardless of what it is, I suspect there’s a good chance they’ll be asking for all kinds of different fin bases on them. Futures, FCS, FCS II, Pro-Box/Gearbox, longboard fin-box style, etc.

I’m happy to help them out with this (as spare time allows) as I think I’ll get a real kick out of watching the difference it’ll (hopefully) make to their surfing, but I don’t want to break any laws in doing so.

So what are the legalities of doing this? -> If I’m interpreting the summary of the FCS vs Surfco judgement (see here: http://www.justice.gov/osg/brief/fin-control-systems-v-surfco-hawaii-amicus-invitation-petition) correctly, I get the impression it’s legal to make fins with any kind of fin-base on them you want (i.e. not just the FCS original-style dual square-tab ones that the court case was about).

And that there’s no requirement to obtain a license to do so, nor to pay royalties to the companies that manufacture those fin systems.

Is this true?

Different story though with the fin-boxes -> you can’t make them without doing the above(?).

'Reason I ask that one is that a lot of my surf-buddies like to collect and ride old boards. So I think there’s a fair chance that one day one of them will come to me with an ancient board whose fin is fine and which they dearly want to keep using, but whose ancient fin-box is busted beyond repair, and is something which you just can’t buy nowadays. In that case the easiest option may well will be to try and fabricate something in the way of the original fin-box to get the board working for them again; would I be breaking any rules in doing so?

In regards to replicating an out-of-production fin for my friend (assuming I can get access to a set of the originals and measure up it’s dimensions and flex rate), will I be breaking any laws in doing this? I’ll be using a different construction method to the originals (and I probably won’t be able to exactly replicate its characteristics because of that), but if I end up doing better than I expect and getting pretty close, what’s the law around that? If you’re not allowed to do that; what’s the lee-way around that/how close can you get to replicating it exactly without infringing on any patents/copyright?

Mind you, the legal information I referred to above is just for under U.S. law - is it different elsewhere (e.g. I’m from Australia and I’m not sure what the deal is here)?

Cheers!

Thanks Larry!
Glad yo hear you are doing well!
Do you use a hard pad for foiling?
And a soft pad for finishing or???

Can we get a closer look at your vice-grip clamp rig?

Larry,

  1. Are you familiar with how Joe Blair of Joe Blair Surfboards in Solana Beach places his fins (thrusters and quads) a lot farther forward than most? What do you think about that?

  2. What is the reason you decided to make Probox a post-glass system as opposed to pre-glass?

Thanks

Great videos of foiling and soft padding the twins. Looks like you have a giant vent system sucking the dust away from you?

I’ll most likely be giving you a call tomorrow after dawn patrol. Thanks!!!

Yes Greg our blower system is like air condition.

Joe Blair gets it, in the Standup world which is the opposite of the Surfboard world. In the Surfboard Prone world you are catching and riding the board more off the tail. In the Standup Surf world you are riding off the balance point of the board which is further forward. People look at only one eliment of surfing which is riding the wave and forget you have to paddle with a paddle which is different than catching a wave on a Surfboard in simple term.

Probox Install is designed to adapte to any board bottom. With a flang glass over you are shaping the board around a finsystem which is ASS BACKWARDS, unless your board designs have NO tail rocker or curved bottom contours!! Another funny thing is a glass over is a polyester mainly install. With so many different board structures these days i see installs that are done like Probox after lamination then glassed over which is more work, go figure.

Dwight, I talk about the sock install on my blog www.Probox-Larryretrofits.blogspot.com




Are white jigs still standard, or did you switch to black?

Dwight, White or what we call natural is standard so we have no color bleeding onto the boards like when we were using Red jigs.

Proboxes are installed like center channels which has no board bottom or structure limitations. This is the way I was taught as a teenager and then it started to change coming into the 90’s when compaines seemed to start cutting corners and going backwards.



Quote from fins:

hi Larry ! what is your favourite fin setup at [if there is one?]  your favourite wave ?   and , why ?   cheers   ben - See more at: http://www.swaylocks.com/forums/shapers-hotseat-larry-allison-aka-probox-larry?page=4#sthash.45Xi1Nte.dpuf

fins, my favorite fin is a 8" Parish/Brewer comdo from 1976 that I ride on my Greg P. McCoy which I glassed at 17years old and Resin pin stripped. Wanye Miyata taught me alot of this Resin art of pinstripping and Dennis Andries taught me how to make a board. This board I rode till 1990 and still have it hanging on the wall  at my house because of the good surf memories. My Boards I ride today are Bruce Grant 6’11" and Mike Dawson funshape 6’11" with the same 8" fin design.

As for best wave I rode that is hard because there are a few. 1) Little Drakes in the Ranch at 3 to 5 feet, 6 guys out for 5 hours. 2) Town Hawaii in April 3 to 5 ft from 5:30 PM till 9 PM at night with a full moon and medium high tide with 25 guys in the water. 3) Doheny before the Marina was done evening glass off 3 to 5 feet medium high tide coming in. 4) Malibu one Dawn patrol morning with 3 of my friends hit it perfect on a Sat morning for 4 hours with 15 guys breaking from 3rd point 4 to 6 feet, until 10 am before over 100 guys were out. 5)Camp Lopez Mexico, left break 3 to 6 feet off the old road from TJ. These were a few unreal sessions that will stay with me for a long time.
