I need to cut a trench or rebate into Knauf board, about 3mm deep, 60mm wide and 1000mm long...I expect a Dremel will do it, but what sort of attachment should I use??
How to cut a trench/rebate in Knauf board?

It's the foamboard sheets available from Bunnings.
I did some work on my layout today which uses the same board using nothing more than an old steak knife and a scalpel blade.

Should have added that i also have the plunge router attachment , this attachment is 140mm across (so 70mm from the center to the edge). Dremel part no. 335-01 . Hope this helps.

You could make what is called a hot knife with some resistance wire of suitable rating bend it into shape you need to make the rebate and make a holder that will allow you to move it along as it cuts its way through and gives you the depth you need in the foam. It would give yo a nice cut, hardly any mess and would be quick to do it. There are videos on You Tube about such things if you want to go that route. It would be wise though to use it outside and wear safety equipment while doing it, like breathing masks and shields or glasses etc.

Thanks for all the suggestions

thinking way way way outside the box here, but guaranteed almost no mess.
Cut out your 60mm wide and 1000mm long section from the board completely using a sharp knife or blade, push entire section down 3 mm and a glue back into place.
If you do not want the 3mm projection underneath, push the piece you have cut out and simply cut a section off the bottom then glue your section back in 3mm from the top surface.

I have recently done the same thing to the knauf board on my layout so as to create a slot for the backscene material to sit down into. I started by using a standard wood router with a 4mm bit, but have since changed to using a laminate trimmer as it is easier to use because of it's size. Yes it does make a mess, but that is easily cleaned up with a vacuum cleaner, or if you're lucky have a 2nd person follow the router with the vacuum as you go.
A Dremel with router attachment would work well, and all you need is a 3mm router bit which I'm sure Dremel make (or 1/8" even).

Hi guys, can anyone recommend where to buy the Knauf boards in Sydney, as it appears Bunnings no longer stocks them? Ideally somewhere that delivers for a reasonable price!
Many thanks

Hi patsstuffnow, thanks for trying to help but you've posted a link to an unrelated (and not useful) product.
I've capable of doing online research and have explored several options, and only found companies that sell large quantities (and charge ~$100 for delivery regardless of quantity), rather than the one or two boards I require. I'm unable to pickup myself from the locations on the fringes of Sydney due to work commitments.
Hence my request for recommendations from members here who may have purchased it recently, since Bunnings was the simple option but no longer stocks the product.

The Extruded foam board from Bunnings seems to be sporadically avaliable from some of their stores and not at others. Eltham Victoria has had it a lot.
Still one can look up Extruded Foam Board to see if you can find similar products.

Just ask at your local bunnings they will check other stores and if available will get it in for you . I managed to grab the last 2 sheets from bunnings kirrawee just before christmas , and when i asked if it was going to be restocked they told me no , but can be ordered in on request .
Hope this helps

Dear Stagehand,
The link I sent was to a KNAUf website. , and among many products they sell is the XPS board in several sizes. A quick phone call to the phone number in the top right hand corner of the website opens up several options.
One was Bunnings as somebody else mentioned.
They can order products off range or check to see if a store my have stocks of the larger sheet 1200 x 2200 which has been removed from the regular Bunnings range.
The helpful person on the line also advised me of a company who stock the larger sheets and does not charge 100 bucks a delivery.
As nobody else has offered any on the ground experience in Sydney it may explain why Bunnings is no longer stocking the larger sheets.
( possibly lack of demand).
Another approach may be to check out if any friends, colleagues, nearby modellers would be interested in buying a large pack and splitting it to minimise the delivery charge. A collaborative approach may even unearth a way to obtain/ share/ hire a cutting tool etc and maybe allow a share of information, experiences and even an extra pair of hands to help you assemble your module(s).
Cheers and happy modelling.
