Mother of all bookcase projects

Sketchup works internally in inches, and converts on the fly IIUC. You can specify what scheme you are working in, but can also override that when you enter figures.

So for example, if working in mm as a global scheme, you can still enter

4" as a dimension. Add that to the ability to automatically replicate, or divide spaces into equal segments etc, and its easy to end up with fractional measurements popping out in some cases. You can round them in the dimensioning tools, but that takes extra steps.

Generally I will work to the nearest mm. There is not much point trying to do much better with things like ply since 3/4" can be pretty much guaranteed to be anything but 3/4"!

Well to be fair, if I needed to make several of them, I can see the attraction of subbing out some of the work... at least until I get round to building a bigger workshop!

[John Rumm]

To an extent there was more to it than just storage - the room as a whole has never really "worked" for me - too much eclectic stuff, and not quite enough organisation. So this was stage one of a re-imagining of the whole room. I have in mind something similar on the front wall to house AV gear, CDs etc...

The 'fur' on MDF is probably thicker than 0.1mm

[John Rumm]

The trick is not leaving the edges of the MDF visible anywhere...

(although the cupboard doors do close against an MDF edge on mine)

Agreed! Magnificent work John. That is *exactly* what I envisage for this Victorian room. However, any shelving I build may just be good enough for the shed ...

I would cut flutes with a core box bit which if just stopped gives a non feathered finish which our American friends seem to like.

I'm not understanding the cutter you are describing. Any chance of a link to an image or web site ?

Even a single core box bit will leave a radius at the end of the cut...

This one:

Used twice - once from each side, to give six flutes with a gap between sets of three.

You are welcome to the sketchup model if you want it...

[Awestruck]

Bloody hell.

Cool. Now all I need is a workspace large enough to accommodate the tools which I don't have. After which, the skills to match should eventually develop. ;)

[John Rumm]

Well the workshop I can't help with (and to be fair I was struggling in mine with the size of that one - no so much making it, but test assembling and finishing it was difficult).

The skill level however to be honest is not that great for something like that. It really is just 6 boxes knocked up out of sheet goods. Its the face frame that makes it look "more", and that was just shop bought

4x1 screwed together with pocket screws and a bit of routing to make it look pretty. You can also buy most of those mouldings ready machined from most sheds.

Tools wise, a router, circular saw and a sawboard, a couple of trestles, and a pocket hole jig would actually be enough for most of it. ;-)

Ah, I thought you had used a conventional round ended cutter used vertically in a router and had wondered at the accuracy of your setup to get the spacing consistent :-).

[John Rumm]

Yup I see what you mean...

You could actually use a variation on the technique I describe here:

Having routed the first flute with the fence, stick a false bottom on the router and superglue a small length of half dowel to the base at the spacing from the cutter you require. You can then engage this in the first flute to set the offset to the next - then repeat as often as you require.
