converting thruster to quad

Well this is going to be my first experience on doing anything to a board besides from sun cureing small dings…

The board is a poly 6’x 19.8x 2.4 swallowtail

I am applying FCS plugs

So any help would be great on how to do it, what i will need, and where to put them

Thanks a bunch

hi surf !

a friend of mine puts his back fins at 5" from the tail tip . he does baby swallow tails or rounded squares for his thruster template quads. He has all four fins the same [thruster] size , toed in towards the nose . he loves them , and has made 5’11 to 6’6 versions. Maybe like chipfish61, you could experiment with putting three plugs each side for either your front or back side fins ? Then you will get an inch or so of movement to experiment with . Try different sized and templated fcs fins in the setup , please take some photos , and let us know how it goes , and which setups you like best . So you can be a part of the communal learning process for all of us , too eh? thanks !

…is it an existing board , that you are modifying , mate ?

Or are you building one from scratch ?

here’s some shots of what “p.sycho” was mentioning [my “bushfire fish”] …

… I hope this helps ?

cheers

" how to do it, what i will need, and where to put them"

[from another thread , pascal’ / 'popeye’s thruster to single fin conversion]

…the fcs foam rubber adhesive backed “template” for drilling the plug holes…

…milled fibre [powdered / ground fibreglass stuff] , pencil , holesaw , resin , catalyst…that’s about it …

Ok I will surely take photos when I do it but as of now I do not have the uhh… balls I guess you can say to commit to it.

it is on an existing board

so i need a drill holesaw thing… this seems like it could be useful http://www.foamez.com/index.php?main_page=product_info&cPath=4_80&products_id=210 , but i’m sure that if i knew what size it is and how deep it should be so i could mark it off to know when to stop it could be just as effective and probally much cheaper. so that information would be very helpful.

also where could i get one of those rubber things?

and could i use old crappy plastic fins that i don’t use anymore to cover the plugs or are those things special?

sorry for all of these stupid beginner questions

The fcs foam rubber thingys are good , because they contain any resin overflow , and help align those little “antennae” type side bits that hang off the fcs plugs , to get the plugs in straight , AND level , too ! … [yes, you can use the plastic fins in the plugs [or make some wood ‘dummy’ ones ]

[tip…[unlike me in this shot] … use white pigment , mixed in with the resin , milled fibre , and catalyst , to give you the nice white border that you see in the BACK two plugs in this photo below…]

then carefully sand the plugs flush to the deck [we used an orbital sander]

…maybe you can end up with a multi plugged board like mine , by also doing the two extra plugs for a single fin setup ?? [just a thought]

Yes , doing that , it would end up a bit more tail heavy ! But , as long as you’re okay with that , then multi fin options are a LOT of fun to muck around with , mate !

cheers ,

ok after measuring my front fins they are 12 1/4 inch from the tail… which from observation seems pretty far compared to most quads.

so when converting should i still make it 6 inches from the tail or should anything be changed?

will be using using crvs in front and longboard sidebites or small trailers from back fins if this makes a difference.

hi mate !

this is only my thought/s, for what they are worth , but …

if you DID put in three plugs for each back fin , then you can have that movement forward or back , as conditions change .

Perhaps with a slightly longer based back fin, to cover some more area [between fins], too ?

… like I said , that’s just one of my options …play around with heaps of different fins , mate , and see what works best for you .

I look forward to seeing / reading your findings !

cheers

thanks for everyones help thus far

as of now i am still trying to make sure i know exactly what i am doing… which now i am pretty sure of i am.

but now i need to find a place for the supplies. my local shops don’t have plugs and they jack up there prices a lot on glass.

so i am searching for a place online that i can order fcs plugs, milled glass, resin, catalyst, marking out template thingy, quality sidebite fins, and… i believe that is it. anybody have any suggestions one 1 or 2 sites that i can order all of those things from (preferebly one)

once i start i will take photos for you guys

well i finally did it and turned out pretty nicely… didn’t use proper tool now did i remember to take photos but it did turn out nicely. if i get the camera working soon i’ll take pictures of the finished product.

i will tell you how it rides and again if i get the camera working i’ll get some photos of the board in use

well i used it yesterday in waist high waves and the other day in shoulder high waves and i was very suprised at how much drive it gets through all of the turns without sacrificing looseness. i was able to do turns that usually would result in total loss of speed.

still trying to get camera to work… may need to get a friend to help me with that

Great to hear! did you get any photo’s of the board with quading?

Cheers Mate!
