Aquarium support / storage

I have come to realise that trend are awful.

Where you trying to do it in one pass? Where you getting a lot of burning?

I think I am coming to agree with you but until I try some other bits I will hold judgement - the long straight bit I bought for trimming my decking boards to the joists worked very well...

I am taking a full depth cut but only a few mm at a time horizontally. No burning but some break out - I suspect I need to think rather more about the direction of travel for each of the cuts

I have attached some oak edging to the edge of my 18 mm oak faced ply - this edging is some 3-5 mm thicker on each side than the ply panel. I need to trim this excess off.

Why make the lipping so much thicker than the ply? If I was doing it I would have made it about 19mm wide so I only had about 0.5mm to take off each side. This could have been done with a plane in a few minutes. If you really want to use a router use a bearing guided laminate trimmer and run it on edge of the lipping with the bearing running on the ply. Not sure what router you have but easier with a small one.

I made it thicker partly for convenience and partly because I'm not very good on the bandsaw and tend to wander a little, sometimes it gets down to 20mm but sometimes it is up to 24 mm

I tried planing some off but then I ended up damaging the ply as getting it level seemed to involve taking a swipe across the grain of the ply which tore it out.

If I use a bearing cutter on my 1/2 dewalt I would need to be able to hold it at right angles to the top of the 19-24 mm wide edging - I would think that this would be very hard - or at least it would be for me maybe that says something about my skill levels? Hence my thought about the router table - that way I can rest it on a flat surface which will take the weight of the component and act as a large reference surface whilst the cutter takes the cut...

Could you use your router on a piece of 4x2 like this to take your lipping off flush(with a bearing cutter).

 

[promhandicam]

. . . or use two fences either side of the ply.

Oh, I see. Could be worth a go - thanks for that.

Ok. I'm with it now.
Promhandicam's solution is best (trimming router with bearing)but it means working at a difficult angle.
I think (will check when I get to the office later and can look at a catalogue) there are some bottom only cutting routers which could be suitable for the way you are currently working....get back to you on that.

the router you sketched is for plunge cutting and will almost certainly always leave "sratch" marks across the surface if you try to use as a surfacing tool.

ah ha! Good I can blame the tool In all seriousness I did wonder if there might be a better bit - hence contacting you. I am confused though by the reference to bottom only cutting routers - I was expecting you to say side only cutting routers as I assumed Id want a smooth non marring bottom to the cutter to brush the ply surface and cut away the edging from the side, but I'll bow to the expert

Hi Miles
There are some surface routers but they are really suited to CNC machines.
Bearing guided trimmers:
As you are only doing short runs I would suggest the Triple flute trimmers from Titman BGT903 as they will give a sharp finish. However take note with the comment about extreme heat build up....though I dont believe that will apply in this instance.

Also be aware that when resharpened the outside diameter will be reduced which will need a specialist bearing...readily available.
You still have to think about the narrow work area but I think the other guys have given you some suggestions there.

Doug
