  • V grooving composite with hand router

    Posted by Myles Brewer on September 29, 2020 at 1:17 pm

    Hi, I’m interested to know if many out there use handheld routers to V groove composite panels for tray making & how successful it is?

    I’m looking at getting a router to cut some new kitchen worktops we have & wondered if it was worth getting a V groove bit to try out.

    I don’t do a huge quantity of tray signs but enough that it could save a reasonable amount of cash & would probably do more If I could produce them in house.

    Are there any do’s & don’ts? I realise getting high-quality bits is probably key.

    We’ve experimented with it, and found the flat bottom cutter better than the V-Shaped one.

    We’ve not produced a ‘live’ job in house, to be honest, for what they cost made up, it’s not worth the faff getting it out, setting it up, and mess it makes doing it ourselves.

    So yes, it can be done!

    I made all of my trays using a relatively cheap router, £100, and a flat bottom cutter as David mentions. If you look at ‘Trend’ router tips you’ll find the one. However I had a 3.0 X 1.5 metre bench which was big enough to accomodate anything I was ever likely to do and that made working much easier, oh and I had a BIG broom because even the smallest job creates a lot of mess. Once I’d cut and swept up I just bonded short lengths of aluminium angle on the inside of the folds.

    We’ve done quite a few using this method. You definitely need a decent v-groove bit with a flat bottom or your material will split when folded. You need a big flat bench to ensure your groove is equal in depth along it’s length. You can buy a router with a connection for a vacuum cleaner. We’ve a Bosch one which we connect to Henry. You can either glue the corners or rivet / screw angle brackets in to hold them in place.

    Check out this link for details, there’s a section dedicated to folding dibond –

    Thanks all. That’s generally great news & think it will at least be worth giving it a go. I’ve located one of the Trend V groove bits specifically for composite which has the flat bottom.

    The mess I’m not overly worried about as I’ll most likely be doing it either outdoors if larger sheets or in the shed if smaller & will probably attach a vacuum to take the bulk of mess away.

    My main issue is having a decent flat surface. Up till now if I’ve had to deal with 10x5ft sheets it’s been a case of laying a 10×5 pallet on the gravel drive & hey presto, that’s my workbench!! Ha Ha! Ohh to have a decent sized workshopRofl.

    I actually have one of the Aldi routers I bought years ago & wondered if that would do but it only takes 6 & 8mm spindles & has 1200w motor which I know is no good for the worktops so I was looking at one of the Trend T7 Routers which should be fine from what I can see for both jobs.

    I agree David Hammond to a degree about the faff & cost saved etc. but when you add in the cost of either collection or delivery of them then it certainly should be worth it & once done a few times the setup will become easier I’m sure.

    David Stevenson, Thanks for that link, that’s quite informativeThumbsup

    I wouldn’t be to concerned about its power for all your doing with it. A 1200w should rip through dibond no problems. The bit we use came from ITC, it’s a 6mm shank so would fit your collet. If your router has an edge guide you’ll find this extremely useful for keeping it running straight at a set distance from the edge.

      The main reason for getting a higher powered & half inch collet router was for doing the worktops but will hopefully be a little better than the Aldi one for use on the composite as well. Both have the edge guide which like you say should help keep it straight although I’ve seen quite a lot use another sheet or offcut of composite clamped on top as a guide.

    Hi im looking for suppliers of the v groove tool for a router.

    Also has anyone tried using a circular saw with just a metal blade creating a flat edge?

      I think Edward Mathius supply these router bits Martyn
