Re: gorilla glue

There is nothing in the description of that product that suggests it's even remotely suitable for wooden boatbuilding. Unless you were to use it in place of 3M 5200, which isn't something you'd use to build a kayak either, I suspect. I wouldn't touch it - why look for something different when there ...

Re: Resize Plans- Squirt

Has any one done this reduction or increase overall? I know some plans and builders simply add or reduce overall lenght by spacing frames. Scaling a boat design changes many factors - displacement, stability, material requirements etc. It's not recommended unless you're in a position to calculate t...

Re: Hello from Bolton, UK

Welcome, Simon. I am building a Zip in the UK. I have bought ply (Robbins Elite - okume ply), white oak and utile from Robbins in Bristol (http://www.robbins.co.uk/) but the last time I needed timber they couldn't offer the lengths I wanted in any of the three timbers I suggested so i ended up buyin...

Re: The Zip is on the NILE, Egypt

I haven't worried about cutting the angles on my transom following advice from others on here - you'll be fairing all the frames later on anyway and you can do the transom at the same time once it's mounted on the build form.

Re: Zip 20" Transom with Modified Tumblehome

Raising the sheer at the transom means you’ll likely also need to raise it at frame 2 to keep the sheer fair in profile. In theory your change might need a change of profile at frame 2 between chine and sheer to keep the curves fair but as the change is minimal you’ll probably be OK.

Re: Donor Boat

I've been facing the same decision as I plan to buy at least an outboard this autumn (fall) when prices are lower. I can probably get a boat, motor and trailer for not much more than the cost of the motor alone (and there's the potential of testing the motor properly on the boat before purchase). An...

Re: New member from oregon

If the boat doesn't live in the water and you don't use it in salt water do you actually need an anode on the motor?

Re: UK Zip Build

I figure the breasthook, stem and frame 5 1/2 (which are what I’ve done so far) will never see direct sunlight so the epoxy finish I leave them with will be how they look forever. The finish as it stands is good enough that when I’m head first under the foredeck I won’t wish I’d taken more care.

Re: UK Zip Build

Using a heat gun is a good idea - it should also make the epoxy flow better and potentially give a better finish.

Re: UK Zip Build

I feel as if I'm climbing a very steep learning curve. I started to encapsulate my frames on Saturday morning, forgetting the critical advice not to do so when the temperature is rising. I made the problem several times worse by using slow hardener - that just gave the air bubbles more time to form ...

Re: Considering Some Skipjack Modifications

I can't comment on all your suggestions as I'm not very familiar with the design but I'd be cautious about a windsurfer mast - they are designed to bend quite easily from tension in the sail and this is likely to be undesirable on a Skipjack - the forestay/jib tension would tend to bend the mast for...

Re: Team

Hi Gary. Yes, the £158 was Robbins Elite. The few voids aside, it's lightweight and cuts well. The £26 sheet of exterior ply was from Builder Depot. I also bought a sheet of 12mm 'Far Eastern' marine ply from Builder Depot (for the frames of a SoF canoe) and that cost £44. The same from Robbins woul...

Re: Epoxy availability in Egypt

I'm using 105/206 for everything - I prefer to have more working time which the 206 hardener allows compared to 205. In winter (UK) I have had to bring things into the house to cure fully but in summer my garage is often over 30 degrees (celcius) so the slow hardener is essential - same as it would ...

Re: UK Zip Build

Thanks, Mike. I've often wondered what denatured alcohol, referred to many posts on here, is - we don't have it in the UK. A quick Google search reveals it's what we call 'meths' (methylated spirit). Purple stuff, right? I'll try it when I'm home but I'd imagine it'll raise the grain of the wood som...

Re: UK Zip Build

My progress on the boat has been frustratingly.......I was going to say slow, but non-existent would be closer. Good news is I've finished building the cycle store so the bicycles are out of the garage and out of my way. I've also completed the transverse bracing on the build form so that's solid as...
