Robbo's Hollow Wooden Pics

I think I got it, I edited the previous message, check the pics.

thanks mate , that’s great …good dog !!

[does he surf ?]

He is going to learn when I do, what kind of board would you recommend for Sweet Pea, he weighs about 80 lbs.

hey Rolly, thanks for the pics of your gluing setup, now… just gotta make one 10ft long!!! and have somewhere to put it!!!

Robbo,

  Not necessarily, another way to do it and get far greater clamping pressure than just putting weights on it would be to place a piece of 2x4, or small steel I beam on the bottom and on the top of what you want to laminate together, directly above each other, place them on edge rather than flat, put a pipe clamp at each end and then tighten the clamps and torque the hell out of them, it is the same priciple as my press. 

Rolly

Just wanted to interject a perspective on the difference between clamping with C-clamps and using weighted objects. I’m sure engineers can easily see the difference, but for me the understanding came out of a project. Several months ago I was tinkering with bending wood 1 x 12’s using boiling water rather than a steaming method. I boiled the wood for about 30 minutes, and then stood on it with one end propped up on a concrete step. It didn’t budge. I warmed it back up for a few minutes, then bent it using two C-clamps and couple of 2 x 4’s (top and bottom.) Granted they were beefy 5" C-clamps with 5/8" threads, but they did a job that couldn’t be done with the weight of a full grown man. That’s something I keep in mind now as a rule of thumb…2 C-clamps > 1 man.

P.S. most of you know already, but probably worth mentioning here for our readers that an epoxy glue joint is not clamped as hard as a polyurethane glue joint.

Great Job!

It looks like you’ve done that a few times before. I really like your homemade clamps; I was thinking of making some to warp the rocker into my board, but I found a Pallet of cinder blocks in my brothers backyard. Thank god for heavy bricks.

Cheers,

Austin

WOW! JUST MADE JOURNEYMAN…Cool.

hey guys, well I finally got some spare time to do some more work on my hollow wooden, so here are the latest pics…

crossribs cut and ready

crossribs in stringer

more…

join of crossrib to stringer

stringer and crossribs with pre-bent rails ready for gluing together.

Looking great…!!!..

Hey Robbo,

Great stuff mate, looking absolutely fantastic!!!

Please keep us posted, with the work you’ve done so far the rest should flow freely into a work of art…

got a bit more done today…

here is the frame “hot glue tacked” together and then glued at joins with high quality construction adhesive (SIKAFLEX) we use it at work quite often and it is amazing stuff, it can take some movement too so it wont “crack” at the joins and lose strength.

here is the best shot I could get to give you an idea of the planshape, remember there is about 35mm all round to go on this yet, that being the rails.

that looks great. it makes me want to attempt one. good job, cant wait to see the outcome.

That’s really interesting Robbo. Keep us in the loop.

Bitchin’

hey guys, well I’m on a bit of a roll right now with this thing! got a bit of time in the last couple of days so I got a fair bit done, here’s the latest piccies…

some thin ply braces I put in the tail to keep everything where it’s supposed to be, basically just while it gets built.

the interior rails with router strips, I will use a router with a “flush cut” bit to take away all what hasn’t got a strip on it on the outside rails, leaving the finished rail line and removing excess ply from the centre (between the strips)

here’s more…

some 19mm thick maple blocking I put in the nose in case I’m brave enough to cut into the finished nose later and fit some nose blocks! they will provide something to stick the nose blocks to if I can make myself cut the nose off!

here’s the frame at this moment awaiting me to come and attack it with my new router!!!

an AMAZING amount of work Robbo ! you must have quite the patience of Job , and the craftsmanship of well…a craftsman !

how thick will the finished board be …I can’t quite get my head around it ?

…because , at the moment , it looks as thick as hickster’s windsurfer blanks were before becoming the "moonrocket " , and the Auslock boards , respectively…

keep the shots coming …great stuff !!

chipster

hey chip, the finished board will be about 2 1/2 inches, it probably looks thick coz I haven’t got the shaped rails on yet so it looks a bit boxy but it’s actually a bit thinner than most boards this size.

hey guys, forgot to say that the timber count so far is 118 pieces of ply and 2 blocks of maple, yep 120 separate pieces of timber…

SO FAR!!!

and that’s just the internal frame!
