hi everyone,im a complete novice so pardon the question,but what is the best way to cut plasticard sheet?

[Tony WilkoParticipant @tonywilko10595]

Hi Andrew …You can cut Plasticard with a modelling knife or a stanley knife.

I prefer a stanley knife to do the major cutting, and a modelling knife for the intricate bits.

Hope this  helps Tony

You do need to exercise a bit of care however. A blade is prone to slip on the shiny surface and you can end up cutting where you didn’t intend to, including removing bits ot your person! It’s best to make several light cuts until the surface is scored about half way through and then the card will snap cleanly to the scored line. Just practise a bit first.

thanks both,do you have any preference on the blade shape?

[Colin BishopModerator @colinbishop34627]

AsTony says, a Stanley knife works fine with a standard blade. If you are using a craft knife then a fairly sharp point will do the job.

Hi, on the same thread subject (plastic), are there any glues that won’t stick to plasticard (high impact styrene)? I’m thinking of using it for the formers on a clinker built, and so obviously, I don’t want the formers all stuck to the planking at the end if the hull build!

I’ve heard that PVA type adhesives don’t stick, what about expoy type glues?

Thanks

Mick

Don’t use epoxy type glues on plasticard,as they will tend to melt the plastic. PVA is your best bet here,or use a shield like clingfilm over the formers,if using a more powerful adhesive. I don’t know if that will protect the plastic formers from the likes of epoxy though. I’d try it on a piece of scrap plastic 1st and see.

pva won’t stick to plasticard with any strength at all.

 

if you tell us what you are trying to stick the plasticard too, then we’ll have a better idea of what to suggest, but epoxy will without any detriment, stick to plasticard[ although polyester grp resin will melt any form of plasticard and abs plastics beyond recognition,

 

 cyano aclylate[ super glue]. will also stick plasticard without detriment, although it will fog up clear window plastic but depends on what you want to do.

 

the best adhesive of course though, is the propretory plastic weld glues.

neil.

ALL DEPENDS  ON WHAT YOU WANT TO DO though.

Thanks Gents,

 

Basically. I want to affix  the formers (plasticard)  to the building base,(probably MDF board or a kitchen shelf) I’ll use super glue or epoxy or maybe old fashioned screws  for that,

 But I don’t want the planking to stick to the formers as I build the hull.

Guess I’ll have to play with the options.

A really good shield for formers when used as you intend Micheal is the backing film from Pro film or similar heat shrink covering as used by aeromodellers. try as you might no glue on earth will stick with any permanence. I have a supply leftover from my aeromodelling days but you could try making contact with your local model flying club and see if any of them have any backing they haven’t thrown out or maybe one of them will be in the middle of a build also aeromodellers tend to be more prolific builders as sudden meetings with hard unforgiving objects are more frequent in that game than ours and model aircraft are far more delicate than model boats on the whole

 

Hope this helps
