Default Quarter round MDF?

Following on from the fluorescent lighting thread:

I'd like to make a really nice lighting trough, end profile roughly like:


Wall
|
|
|
| |
|----O

Try to imagine the O represents a smooth curve from the horizontal to the
vertical. Horizontal about 4", vertical lip height about 1.5-2"

To be painted in white emulsion inside and out and run continuously around
the room.

I've got a feeling that something might exist, but I can't for the life of
me track anything down.

Is there a product like this, or even just quarter round MDF that I can
joint onto a straight bit? I guess it will need to be 15mm or so thickness
to have the required stability.

Cheers
Tim

Pre primed MDF window board from Wickes. About 200mm wide, so one quick rip
down the middle gives you both pieces. Cheap as chips.

4 inch pencil round skirting plus 2 inch square architrave would be
cheaper and quicker. Both available in MDF from Howdens -

Pipe boxing, mdf or plywood.

Wow. The 2nd link in particular looks nice. I could see some of the 5mm ply
being a strong possibility - nice smooth curve and dimensions that I think
I'm after...

Although I was going to leave some pipe drops to rads on show, I'm tempted
by this stuff - it looks pretty nice. Thanks!

Hi,

I don't think that'll work. I'm after something with an upturned lip rather
than just a rounded end.

Cheers anyway,

So, you want 'pouting' wood then?

I used upside down skirting (nice proper wood) glued to a spacer for my
window lights, but I had them shining down not up.

Having looked at the prices of the pipe boxing, and the corner radius, it
might well be better to try to fashion something out of bull nose skirting
with another bit glued on.

I was very pleased the way mine turned out across a window bay with a couple
of 15w strips behind looks v good. Only shame is I haven't been well enough
to finish the decorating to go with it and it's bound to be spoiled if SWMBO
gets someone in to finish it...

Why not make the boxing out of MDF and use a router to make the edge
round?

No router...

But having looked at Wickes, a bit of bullnose MDF architrave and a bit of
bullnose MDF skirting should give me the required dimensions with no cutting
(except length).

I reckon I will make up a number of troughs (the hardest bit getting good
alighnment of the 2 pieces to make the join invisible).

Then I'll treat it like coving and run it all round with mitred joints after
I've calculated the best height to give a good ceiling wash without the
tubes being visible.

I've come to the conclusion that

a) I can't afford dimmers (that get's expensive fast)

b) I'll standardise on 2' T8 tubes. There are 3 short sections that would
benefit from 2' tubes. 3 x 2' tubes for the 8' wall and 4 tubes for the 10'
wall.

There are Philips HF gear units that drive 3-4 2' T8s at no more expense
than the same type of unit for 2 x 4' tubes. Then I'll only need one type of
tube in the spares box and it will be nice and short for easy storage.

I'll just have to take a chance on the brightness, but as its sole function
is to add "daylight mode" to the room, with a GU10x4 spot for the main
lighting, I think it will be fine.

Cheers

Tim

But does MDF route nicely? The surfaces is hard and smooth but the
core tends to be a bit soft and fibrous.

Hmm- I see from one of their pages

I will have to hide my shed:-

Quote:-
In the Conservative Liberal Democrat coalition agreement there is a significant
strengthening in the penalties for the use, possession or importing of illegal
timber and timber products.
The exact details could not be clearer p7 under section 11. Environment, item 14
"Measures to make the import or possession of illegal timber a criminal
offence."

Yes, I do need a router, but ideally I'd like to do with with minimum
effort, just gluing, cut the ends (mitre) to go round the room[1] and hang
on upside down shelf brackets (between lamps) and a batten along the back
edge.

[1] I'm undecided whether to make stand alone lamp boxes or to run it round.
I think the latter will give a certain continuity. But again, it might look
weird for the bits that don't have tubes in?...

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Tim Watts saying
something like:

I've come to the conclusion that

Its also relatively easy to select multiple brightness levels when you
run a tube way below rated power (with filament heating to
compensate), this is semi-easy to do using large tubes, which makes
the whole setup even cheaper. And since you can in such a setup start
tubes at reduced brightness, low cost magnetic ballasts are more ok.


b) I'll standardise on 2' T8 tubes. There are 3 short sections that would
benefit from 2' tubes. 3 x 2' tubes for the 8' wall and 4 tubes for the 10'
wall.

There are Philips HF gear units that drive 3-4 2' T8s at no more expense

To be honest, brightness is one of the biggest deals, and needs to be
right. Suggest a little experimenting to make sure you get close. You
can use filament bulbs and translate the power required using the
different efficacy values for filament vs tube.

I bought one, but then thought of the skirting board, and haven't found a
use for the router after all: shame.

It routes well enough for something that will be emulsioned. The routed
ends get a bit more absorbent, so its harder to finish smoothly with
varnish.


I usually give the edges a wipe with filler on a rag. After a light
sanding, they take a finish as well as the faces.
