Can you recommend a small high quality 'square' / 'speed square' ? (to help cut accurately at 90 degrees)

[ship69]

Hello

Any recommendations for a small-ish high quality "square" to help me cut accurate right angles (e.g. when cutting / scoring small pieces of styrene sheet)
- Ideally I would like a "speed square" - something that lines up easily against the site of your cutting board / work surface.

- It must have easy to read metric measurement markings.

- I need to be accurate to a fraction of a millimeter.

Background

I need something to help me cut 90 degree angles. I am told a "speed square" is a helpful device as it lets you quickly align with the side of your bench/working surface. It would be helpful if it had measurements on it too.

I have one of these but the finish is extremely rough & bumpy absolutely awful.

"Swanson NA202 250mm Metric Speed Square"

http://www.ebay.co.uk/itm/Swanson-NA202-250mm-Metric-Speed-Square-with-Instruction-Book-/181712888336?

I have tried sanding it down which has improved it but the markings are so large and deep that it makes everything too inaccurate.

So far I cant find any model supply websites

i.e. What to buy and where to get it?

So far (via alternativesite.net) I have tried:

(I rather like the look of this thin beam square, except no markings http://www.micromark.com/thin-beam-square,8426.html)

http://www.allcomponents.co.uk ==> no result for squares of any sort

http://www.ashfordmodel.co.uk ==> No squares of any sort

http://www.cornwallmodelboats.co.uk ==> only "Engineers Squares" but they have no measurement markings on them.
http://www.craft-products.com ==> no squares...
(But this "Mini Mitre Block" looks interesting if I could work out how to use it! http://www.craft-products.com/pb102-mini-mitre-block- is using a saw more accurate than scoring and snapping styrene?)

http://www.eileensemporium.com ==> "engineers squares" & "set squares" but they have no measurement markings on them

http://www.ema-models.co.uk ==> only "Engineers Squares" but they have no measurement markings on them.

http://www.finescale.org.uk/ ==> no result for squares of any sort

http://www.hobbycraft.co.uk/ ==> seems to be kids stuff only

http://www.homebase.co.uk ==> limited. No speed squares.
http://www.micromark.com ==> USA based not UK. Everything in inches.

http://www.modelshop.co.uk ==> no squares with markings

http://www.nairnshire-modelling-supplies.co.uk ==> No squares of any sort

http://www.scalelink.co.uk ==> no result for squares of any sort
http://www.westbourne-model.co.uk ==> no squares, including no speed squares
http://www.wizardmodels.co.uk ==> no result for squares of any sort

https://www.wonderlandmodels.com ==> Engineers square with no markings. Hard site to search

I have been trying to avoid amazon because there is so much of low quality build, and repetition of the exact same stuff designed for other uses... which I dont want!
Likewise eBay with the added problem of quality & legal concerns.

Any suggestions/tips for precision, small scale working (esp with styrene/ABS sheet)?

Try somewhere like Toolstation or Axminster - they'll sort you out.
