Get some other bits and pieces while your at it, always good to have a good stock on the shelf and only pay postage once!!!!

Just noticed they do clear Perspex for windows

You're getting the hang of it.............just be careful the missus don't find out..........

6mm ply is way too thick for a model boat, thin birch ply will give you all the strength you need.

I built a full size dinghy from 6mm marine ply, and its plenty strong enough! The ply is guaranteed for 15 years.

For info, marine ply is usually resin bonded and guaranteed to last a number of years ' depends on the specification.

WBF ply, is Water and Boil Proof,..self explanatory, but wont last as long as a good marine ply.

Cheap ply will splinter and fall apart easily and quickly, and is very hard to get a good finish with.

You can probably guess which is the most expensive!

Do you advocate 3mm for the sides, bow and stern, Ken?
Or for deck and curvy bottom ?
I used 6 mm for the sides and ends.

Local timber merchants have offcut bins at greatly reduced prices
Even our BnQ have an offcut bin with useable sizes for about 20 to 50 p a throw.

Use just the 3mm to build the Springer with.  It'll be tough enough to stand on.  No point in all the excess weight of larger timber.

Hope this helps

So marine, then wbf then normal... In that order?!?!?

Yes I really do need it explaining to be sure....

If you've got the equipment to cut it up,  you can sometimes find the backs of old wardrobes, the draw bases from old furniture can supply some reasonable, usable materials.
Call down at your local charity shops that sell old furniture and ask if you can have a rummage in their skips (for a donation of course!) some of the Swedish furniture store products had some nice ply backs too.
More modern products use hardboard and MDF.....not so good for boats.

Gentleman

With regards to a springer, can I have some advice with regard to batteries and power?

I am intending on using SLA battery/batteries, so...

- 6v or 12v

- one or two batteries (am thinking about stability, so even if only "using" one battery, I will need a second on the other side of boat to maintain stability?

After some research I am thinking 2 x 6v 4Ah batteries wired in parallel to give 6v 8Ah........

any advice or pics you can attach would be great!!!

[Tug-Kenny RIP]

I use a12 volt lead acid battery at 7.5 A/hr.

If you lay it down sideways across the bottom of the hull whilst doing a float test in the bath, you will be able to balance the craft. You can then mark it's position and make a small box frame to drop fit it in.

Hope this helps

Thanks Kenny 

I assume you have it mounted centrally though for stability???

Any pics???

[Tug-Kenny RIP]

hi Dave,

I have a look tomorrow. The steering servo and receiver have to be in place before you balance with the battery, but it really is a piece of cake.  Leave room dead centre front to back. I still use mine for rescue duties as they are trouble free craft.

Cheers
