Hello all, I have decided to have a go at building a fishing boat "Anna 2" I picked it up off fleabay for a few quid it has been started  but I can disassemble or modify most of it, my problem is the trimming of the plastic hull it looks like Stevie Wonder has had a go at it, what is the best method of trimming it to the line, I inherited my other boats so have not had to face this issue

[Brian60]

Several ways. You can follow the line with a Stanley type knife, you have a better grip and more control over those than a standard craft modelling knife.

Easiest way but the one with more chance of going wrong is to use a cutting disk in a Dremel type power tool. You not only have to be careful to follow your line closesly, but also not to linger in one part too long or the plastic will melt. Using this method its best to do short parts say 1 inch long then withdraw the blade to allow the plastic to cool, then repeat until complete.

Always give yourself 2mm or so to the cut line, then sand down to it with a block.

I am using a dart to remove the parts from the plastic mouldings on my deep dive..

[Gopher]

A dart, what a throwing dart?

[Gopher]

I do have a demel type tool with a flexi shaft and a mini saw blade, the plastic is so hard I didn't  think a Stanley knife would touch it

Hi Gopher, use the knife to score the line then snap the excess plastic off the gentley sand to complete

Is a Stanley or a serrated blade best?

[jarvo]

Stanley blade, make sure it is new and replace it often, probably twice per side

A dart, what a throwing dart?

Yes, worked so much better than a knife for what I was cutting, followed the grooves so well..  Just scored it a couple of times, and then snap's off, plastic is quite tough on some of the parts but has worked so much better than when I used a blade on the club 500

[Gopher]

Thanks for all the advice, I shall have a go tomorrow when the malt has worn off

And you should be able to sharpen it repeatedly. Good idea!

[Gopher]

Well, that's done I did one side with a dart, I must confess it worked better than mi thought it would, the other I used a wallpaper trimming tool, the one for getting into corners that takes the Stanley blade and that worked as well, so I'm a happy bunny, thank you all again for your help

Hi longbuild I think using a dart is a bit hit or miss!
regards Roy

[Gopher]

You have a point there

[roycv]

Is that another feather in the cap, or don't they use them any more?  Maybe these 'throw away' remarks should stop!
regards Roy

Umm very Bad..

As regards the corners, all Again used the dart to score all around an then the Stanley just to cut down to the edge, On the 2 cut aways I have done I used a Stanley on the club 500 and the dart on the Deep dive, If I did another cutaway it would definitely  be the dart.
