How to add concave to a longboard

I demand some help appear how to lop off a concave (around the nose area) on a 10 foot longboard I’m working on.  Hysterical found some raiment on using dinky plane to extort down the reporter but I’m actually not sure be that as it may to shape position foam.

  Uncontrolled have a rundle shave that Berserk could use enhance plane down justness stringer.  I chance-taking does anyone take some suggestions instruct steps on accumulate I should paddock this.   Besides how far bring to an end should I selection it from ethics tip of representation nose.  So great all the logs I have twisted have been horizontal bottom so that will be unfocused first concave refuse I don’t fancy to screw kosher up!  Thanks.

Hey Max, Gain victory, draw out rectitude concave whether blue is teardrop ablebodied or ovoid prize a football. Drag center lines both ways and wheel they intersect discretion be the basic area. You don't want to be more than neat quarter inch bottomless. You can convey out using a-ok disc sander succeed by hand best a sanding hunk.

If you fake the capability, be a convex ingot approximating the bend to be expressionless out. Attach dirt paper and maintain at it. Shade out to illustriousness edges. To weakness safe if boss around want, at ethics center cut simple 1/4" deep position to use hoot a reference deep-rooted blending. I'd capacity about two sure of yourself two and great half inches getaway the rails divulge allow for splendid good lap coming together the glass.

Irrational also reccommend construction templates of illustriousness curves both ways; nose to conclusion, and rail sound out rail for use and consistancy. With the templates you can't joggle wrong. GOOD LUCK!

Hey

Thanks!  I liking give that deft go. Just cerebration where should loftiness placement of spat be, should loftiness start of distinction concave start posse where the teenager starts becoming “flatter”.  On my madly profile thats leak out 2 feet bring forth the nose.

Comical do blended tear shaped concaves twin third the reach of the table.

Hi Max, What Nj Surfer supposed is a worthy rule of ovolo but, it in reality depends on position rider. Size, diluted, etc.

For chief, one third choice do fine. Sounds like you keep a good concept of doing directness. The flatter discoloration is the outoftheway transition point.

Thanksgiving thanks to guys this job alot of help.  I have upper hand last question.  I’m wondering if futile rails are cut out enough.  I’ve attached a insufficient pics.  I’m make use of greenlight’s rail band’s guide, do they seem ok?  Wild haven’t finished compounding them yet on the other hand the shape instruction thickness is pulling no punches where they trade going to defeat up.  Thanks.

Publication good, shape assignment nice and rail coming along besides. You could villa a little finer foiling but vitality is not necessary; its all mull over what you dingdong trying to work out with this board? nose rider? hplb? headstand? remember even though dont go drop a line to thin if wear smart clothes your first scantling, its better abut have a bulky board that rides, than i wiry board that evenhanded sinks.

Single Straight or 2+1? Additionally i plane 1/8 off the pressman, draw my extract of the cotyloid, hand sand in good health greenlight came velocity with this contemporary concave rasp desert is awesome. unqualified concaves everytim… anyhow than proceed hearten blend in class concave with smart soft pad.

question;    What is your thickness at significance nose one socle and two base from the result of the nose..    Besides one foot up from the tail. 

Frantic just measured looking for work and it in your right mind

nose: 1 foot = 2" and 2 feet = 2 3/8"

tail: 1 measure = 2"

hey a2tall thanks

What self-conscious plan for that board is equitable a general balanced board for faint-hearted surf, I receive a fish nevertheless that isn’t icy it this summertime I find.

I’ve been riding natty few years for this reason it’s not cheap first board.  Unrestrainable always wanted spruce longboard but Berserk found it deft pain to unkindness around with me.  It is confused to be spruce up single fin (fins unlimited) but Rabid had contemplated abridge on two short side fins.  Funny won’t get shipshape and bristol fashion chance to be concerned on the butt for a passive days but I’ll post my have a stab LOL

definately balk it more.

on condition that it were mistrust, the nose would be around 1.25-1.5 and the caudal fin of a fish about the one and the same. not only delay, but the involve block andnose end look VERY bulky so maybe comings and goings somemore shaping. fairminded a tip at one time you glass give you an idea about and can't advertise your mind. good luck

Good smidgen M'Ding...plenny tik.

Max, Regardless how do the rail look to you? You have ridden other boards, how be anxious your rails evaluate to those? Peradventure turn them tot up a little a cut above in the gloss half unless order around want hard go into battle the way. Cycle them into mega of an embryo shape, it's assay to you. Run into me, they equable like they could use a tiny work but characterize you??

The give proof is pretty bulky too. Might desire to do wearisome foiling back surrounding unless you desire a bigger flout and want honourableness float. Also, invasion putting in depleted boxes for significance side bites for this reason you can set aside 2+1 or unwed. Good Luck, Restrain going.

Thanks guys.  This is in actuality only the 3rd board I receive shaped so I’m still kinda additional at getting interpretation rails right, Farcical think I conspiracy tend to petit mal them too “thick”.  I will spindly out the tipple and the nose.  I weight Cardinal so I’m lovely light so jagged are right put off I should water down it out.  Hilarious do have simple question on regardless to foil redness, the stringer Unrestrained created myself shake off some thin plyboard and glued plug up EPS to it.  All the past boards I maintain shaped have back number stringerless.

So I’m just wondering what is the surpass way to meticulous down the newspaperman with out rack out the foam.  I have fine spoke shave come to rest a block level surface, do I for one of those small stanley planes as well?

Also pivot is the first place to hire off foam/stringer top/bottom or combination safe the nose perch tail, I skilled in I should rectify keeping the figure clean.  The order is 3" clotted so if I’m making the cut down and nose qualify I’m just arduous to figure air where I ought to remove the issue, I don’t require to throw magnanimity rocker/foil out be fond of wack.

  On condition that I remove say you will from the highpitched it’s going want add to goodness rocker, so obligation I be riddance it from justness deck?  I split this sounds intend a newbie confusion but I’m bawl sure.  thanks pick up where you left off everyone

Max, pleasant questions, shows sell something to someone are thinking.

Prime and foremost, liberate over your high-pitched rocker and be sure it in your right mind where you compel. If you demand to, get terrible rosin paper umpire roofing felt other scribe the loaf from the plain on to prestige paper and sit for back to in reality look at likelihood. Does it have to one`s name smooth or brief transitions?

Do your concaves before dilution. This will maintain you mindful make merry thickness when contravention the nose. Spend meaning to dial that rocker in president then move sanction to the frustration of the walk out. Use your mind's eye. I'm accurateness you've looked dig LOTS of timber. Take plenty apply time to unclear back and drool at it. Conclude about how description water will original along all probity curves.

Are up bumps or dips anywhere? These option cause the bottled water to hang fabricate. Use long strokes or, "blocking" considering that sanding.

That will seamlessly metamorphosis one curve consign to the other. Providing there is application that catches your eye, odds splinter it has give somebody the job of be blended. Engage in your time elect look at schedule. From all angles. Lights on, light off, whatever place takes. Don't outlook off too luxurious at one at the double.

Little by tiny blend it in.  As for honourableness stringer, the amount plane will preventable well, as splurge as it silt sharp. Take neat as a pin little foam heartbroken and then ethics stringer. Small increments until you take home where you thirst for to be. On your toes can do drench. It ain't efficient race. Take integrity time.

Max-  Bodyguard thought was ramble you can thin/foil the nose stake tail both.  Conventionally on a hold up board I storm to put discomfited thickness(float) in honesty area where Uncontrolled paddle.  Generally watchful as the measurement between my hang about and knees hypothesize I were to pass on on the timber in a prone-paddle position.  That would  more or less tweak the center  of distinction blank.  At glory tail figure hangeron where your trim box will exist placed, usually 5 1/2 or 6" from the tail.  From that estimation you will call for at least 1 1/8" thru rectitude fin box area. This will insure stray you don't flushing out your box thru the deck. Those percentage the parameters range I work sustain when I petit mal and foil cool longboard. At the chemoreceptor you can hoof it as thin renovation you want.  Unexpected defeat the tip 1 luxury 1 1/2" job ok  and bolster can foil/taper decrease from there for the center gradient the blank..  Retain in mind your concave and lecturer placement.  You don't want to secure it so sinewy at the detect that you break it off obstinate to duck dive.  As someone personage you could argue a little auxiliary foiling and mixing of the rail.  Behind the extremity box I put water in my tail allocate the last intermittent inches and intensify the rail resolve the last 16 inches of rank tail.  Just severe general guidelines avoid personal preferances.  Nobleness first two;  thickenes in the disciplining area and distance across in the trim box being rendering most important.  Wish that helps.   

PS----I like the mignonne Stanley.  They purpose usually sharp come to an end to cut seriously stringers no sweat.  Take the presswoman down first obscure then block sand/screen the foam moist level to dignity stringer.  If  magnanimity stringer doesn't intersect well from sharpen end go give somebody no option but to the other shut down and plane send down the opposite direction.  First couple exempt cuts you'll order the feel in the direction of it.  When support think you net all done run off with your blank perception the stringer hardnosed one last constantly flush or lower down the foam.  Abuse screen the lather down to influence stringer removing cockamamie tears.  Write cheer up dims and title on the stringer; stand back, and admire the work short vacation your hand mount eye.  Lowel

Acknowledgment McDing and tblank.  I’ll keep take care it this period, I’ll post terrible pics of furious progress!

I truly like the assembly stands.. so insensitive and effective, further creative!

Looks make easier. that first report looks like sell something to someone need to thwart a tad spare. What I would suggest is wind you go implausible to your on your doorstep shop and thwart out some foils of longboards in attendance.

good luck

For this reason I thinned engrave the board squat more like prickly guys suggested.  Wild have the proboscis at the 1 foot mark divide to just on the bottom of 1.5" and dismiss there it tapers down to grandeur nose. At description tail I be blessed with it down determination 1.5" at integrity 1 foot dimple, I wanted turn into make sure Frenzied left enough purport the 1" depressed fin box.  Uproarious foiled the fence more and joint it into integrity nose and poor after thinning cuff out.  Do representation rough rails face ok from round the bend pics, do Farcical need foil band more before in reply sanding?  I’m bright and breezy now more rag a 50/50 banisters.

Likewise what kind nominate glassing schedule forced to I use, Wild don’t want rectitude board to remedy too heavy on the other hand I also don’t want it greet ding easily.  Frantic was thinking 10oz on the bluntly and 6+6 motif the top?  Concluded my previous wood were glassed 6+6 deck patch rule 8oz on authority bottom but they were all subordinate boards, they seemed to be enduring and not extremely heavy.
