Fins

just got the shaping 101 video, didnt quit get the fin placement thing??? are there normal measurements as to where to put 'em or do you take measures off of a board you alredy haveor what??? Mr. T

if you are making a similar board to one you already have,use those fin #'s for reference…look at your friend’s board…see what they have…or let us know what your making, maybe someone can help

dont know what i’m making, was just curious if there was a rule of thumb for the fin placements(tri-fin) and will more than likely use FCS. maybe they have a template, I dont know, like I said i’m supernew… Mr.T

4" maybe, but I dont know what kind of tail you are shaping or how long your board is etc, etc…You going single, tripple or quad ? http://www.geocities.com/wunderboyi/ninetysixpercent.html

go for this as posted by Jim from lokbox: Under 6’10": 3 1/8 to 3 1/4 from tail for back fin. 10 and 3/4 to 11 1/4 from tail for side fins… just depends 1 in. from rail on side fins with 1/4 in. toe in, and 8 degrees cant for single concave, 7 for doubles, 6 for flats, and 5 for panel vee’s. http://www.surfboardglassing.com

What would the placement be for a longboard tri-fin set up be? Using a box and two small side fins? Board around 8’6"?

Well, i’m no shaper, but thanks surflab…i’m flattered. It’s just a generalization from the shortboards I see. I have adjustable fins in my boards, so I usually try to find a “central” location for my marks. Usually it’s where the shaper marked it, then I can go up or back from there 1/4 in. Seems the front fins were up a bit further in the early 90’s, like 11" or 11 1/4". Maybe they changed for the new rockers these days!?
