Temporary shaping bay

Post by JET01 » Tue Jul 26, 2016 8:00 pm

So I've got a hair brained scheme that I want to turn my garage (Cronulla unit) into a temporary shaping bay.
Never done any shaping before.

If I line the walls with tarps. Use some Gaffa tape to get enough of a seal to control the dust. Then some lights on pedestals like what tradies use for renos so that I can see the shadows and lines.

A. Reckon it would work.

B. How much do all the mandatory hand tools cost to get shaping and glassing. I have a small electric hand sander that I can use.

Id love to shape a few boards over the years.
Probably start with an egg to surf instead of my 6'1 wedding present single fin. Then maybe a fish.

I might get crucified for mentioning it, but midget does computer cut pre shapes.

Otherwise, honestly you can do a board with stuff from Bunnings. Planer is good but you can fkukk it up very easily. Straight piece of timber with sandpaper glued to it in different grades to rough out. You need to buy "screen" though to finish the rails. It's messy and hard but fun to do. Get the blank closest to your finished dims. If you have to take heaps of foam off you're way more likely to fkukk it right up.

UV resin is a must.

Those tradie lights give off the wrong type of light and would be very hot, flourescent light gives off a soft diffused light which shows up high and low spots. one each side and one above is preferable.
A Surform is the best tool for shaping, the electric hand sander can be used for sanding the fibreglass but is not the right tool for sanding foam.

Best way to shape is slowly, one step at a time and after each step stop and come back later and examine what you have done with fresh objective eyes, looking at the job from various angles with just one side light on is the best method for critiquing mistakes.

Tip
Hang fluorescent light box from the ceiling so it can be lowered to just above the board level
That will show up all the imperfections as shadows as you whittle the foam blank away
Order a shapers pad with Velcro type 80. 160 and 240 grit gauze sheets

Blank, surform, saw, razor for stringer shaving, router hired from kennards, couple grades of sand paper, I used an upside down ironing board with some tweaks for the stand and it worked great. Broom and dust buster to clean.

Didn't glass it, never would as I'd be spewing if I f&cked the the thing up after all that hard work.

But please listen to the experts here ( not me). I'd be interested to hear now some of the guys draw up their templates.

Did a few bodgy looking boards. All surfed ok, one, a keel fish, was magic. Way thick and unrefined but just worked so well. Surfed it for about 3 years 90% of the time.

For template I went to Bunnings and got a 2.4m long strip of oak I think. About 12mm wide and 3mm thick. Put a sheet of mdf on garage floor. Mark ends of board and wide point and also 12" from nose and tail with dots. Small gauge nails in the dots and bend the stick around the nails to get curves. Hold with foot and draw outline with pencil.

I read this old book and got a hell of a lot out of it. It's not what you asked but it's worth a read (can be heavy going on theory). It's probably completely out of date but I used the basic principles and the board I made works a treat, I tried to emulate V and modern concaves - probably broke every logical rule in any shaping book but f&ck it.

You don't need to rout the fin plugs if you get it glassed. I used Larry lockbox fins which was tricky I'd go with FCS 1 plugs.

Ta for info on template BF - I winged it last time

What Carvin says about patience, a good rule is 10-15 strokes of tool or sandpaper, check then repeat. This was good advice.

Template
Download the free version of AKU shaper
muck around with it till you have the outline shape you like
Print it off to scale on your home printer - means taping together a bunch of sheets - but works

Wow thanks for all the tips gents.
Won't be getting into it any time soon, but nice to know it's pretty easy to get the tools required when I get a chance.

I've lately been thinking of trying to shape a wooden midlength. Not sure if it's worth the expense to Fcuk up an expensive bit of balsa. I think the chances of success on the first go would be remote but I'm kind of keen. I've got access to a few tools and the space for a while. I guess if I keep it simple. Glassing facilities on the south side of the Harbour is a of a mystery.

Riley I'm sure will make the blank for you, roughed out close to your dims. Then you do the rails etc. A balsa 8'er would be sweet as.

Plenty of hollow timber kits available online
Have been thinking of doing one myself one day, but have a few more shapes to get out of my system first

I guess the hollow ones are more shaped than a blank. I've checked out Riley online a few times.

Yeah, so I believe. What about the rails though?

Grant Newby has come up with a good method for building a paulownia wood on foam surfboard.
No need for lots of clamps.
The cost of clamps would be about equal to the cost of a vacuum bag set up with small compressor.
Would be cheaper to hire a compressor for the day.
No need to glass, he seals with lanolin but lanolin is a bit sticky and therefore can pick up the dirt, orange tung oil is the best natural seal for paulownia or you could seal with epoxy.

Scroll down to second page to get a brief idea of his method.

Or scroll down these blogs for a more detailed description.

Funny you posted those Marvin
I just spent a few weeks going through each of those builds over and over again
re lanolon - woodbudda just coats them with an epoxy resin
