Tool for accurate cutting of plastic strip??

[BattleshipBob]

Afternoon

Is there such a tool/jig for measuring and then cutting plastic strip etc with a nice square cut!

Trying to make brackets but not sure how accurate the length is (have ruler) and when cutting the ends are not square

two tools that may do what you want

Its the scurge of all scratch builders - a straight and level cut. There are tools out there (Some very expensive) that are worth investing in especially as Chris says, if you have multiple cuts to do. The Linic cutter is okay but the blade does not do a perfectly square cut. It is certainly better than doing it with a knife though. The RP Toolz Mitre Cutter is the top of the range at just under £100.

Hi Bob
I'm with Steve on this. I have a cheap cutter and although it works it is not able to cut accurately enough. I bought an RP Tools cutter and it works very well. I suppose you get what you pay for.

Depends upon the thickness of the strip, but I’ve never needed those sort of tools. For thinner stock I simply use a scalpel and a two inch engineers square. Hold the strip against the thick part of the square and cut it using the thinner part as a guide. For thicker stock I use a razor saw and a saw cutting guide. To measure stock accurately I use a pair of spring bow dividers with screw adjustment and set them using a steel rule. If you need a lot of something make a simple U shaped jig with plasticard and use it to cut the strip repeatedly and to the same size.

I'm with Christopher and Tim.
No need to buy these 'Special Tools'

But again, everyone to their own. :thumb2:

These gadgets are probably fine, but an accurate, straight and square cut on the common thicknesses of plastic card can be easily obtained using nothing more than a sharp Stanley knife and a METAL rule or straight edge.....and what's more it works, and no one on this planet can write otherwise - So there.:tongue-out3:

For multi strips, I just use the first strip off the production line as a template and mark the next accordingly. If you do end up with minor differences then, as Chris suggests, use a small file.
I don't use a scalpel for cutting plastic strip. This surgical weapon is designed for cutting skin, not plastic strip. I tend to use mine for just scraping seams and scribing board.

Thanks to you all. Cannot see little old me doing a huge amount of scratchie stuff but StuG crews did add all sorts of brackets. In fact had a go today will post, not bad??

If the masses hadn't invested in a guillotine or two in France in the 1790s and relied on a bloke with a Stanley knife the revolution may have turned out very differently. Sometimes only a proper chopper will do :tongue-out3:

Need, maybe not, no. But many tools you don’t actually need, do make your life easier. Like screws: sure, you can put in a hundred screws using a simple screwdriver, but you’ll be done quicker and with less pain in your hands with a cordless drill with a screwdriver bit. In this case, if you need a lot of bits of strip all the same length, one of these guillotines makes that far easier to do than with just a knife and a ruler.

On the other hand, buying a guillotine if you only need it for a few pieces and then hardly ever again would be wasting money, of course.

Bob I remember Simon telling me that I was better to buy some plastic strip of the size you need. When I started to cut plastic card into thin section for windows they would bend. I had asked Simon what was the problem, he replied it was the stress on the plastic causing the bend. I now use either Maquett Styrene Plastic Sections, or Evergreen. John sells the latter in the shop.
The Balsa cutter that Gary has mentioned I have and would certainly NOT attempt to use it to cut plastic strip. The strip is too thin to enable the cutter to run against the edge. Buy the section ! and save yourself a lot of heartache.

[Tim Marlow]

The other hint John is that styrene sheet responds better to a score and snap technique than cutting right through. It puts less stress in the material and also produces less of a “furrow” around the cut. Evergreen strip is excellent in my opinion, it seems to be “sawn” and is completely square, especially the thicker sizes.

I use one of these for thin stuff up to about 0.25mm. Not tried it with anything thicker myself, but could be worth trying. Not desperately expensive, you could probably find one for about £15.
