Just for fun, a quick photo of the table in the living room right now, lol.

Looks familiar :)

Ooooh that is nice! I don't think it will save alot of space for me though because the gantry height, plus z-axis motor and machine frame end up about 65cm, and the width is only about 85cm. I think I'd prefer easy clamping. That said, I could easily turn the machine on it's side if I want.

The gantry is offset by you being able to go upto 4x4ft. Generally a 4x4 will stick out at least 1400mm from whatever wall its pushed up against. Vertical would be less than half that.

All the router bits I have are 6mm shank, and I have a fair bit of money in that. I also thought it was possible to just buy an ER20 collet... nevermind!

When you say router bits do you mean the regular 1/4" collet types with straight flutes? They'll work fine but you might want to consider getting yourself some end mills. These are generally better quality, plunge much better, remove material better and last longer.

Use up what you've got and once they're starting to dull get yourself something like these:

They're really cheap for what they are and were recommended to me by folks like Jonathan and Jazz who've used them to cut aluminium. They'll eat MDF and ply for breakfast and last ages.

So are you doing custom built speakers professionally now?

Pretty much but nothing official. Its mostly word of mouth but I hope to bring a small lineup of speakers eventually. There's a lot of planning involved before that can happen not to mention prototypes, listening tests, crossover tuning, auditioning. I had hoped to have a floor standing speaker available before the end of this year but I've recently taken on a custom project for Arthur(Ackcheng on DIYA) over in Hong Kong and its scale is very ambitious. A total of 8x 10" drivers, 4x 8", 4x 5" and a pair of ribbons all housed in 2100mm x 320mm x 750mm cabinets. Its the audio equivalent of the Deathstar.

And last year I designed(not built) a huge OB dipole line array with seperate ripole sub stacks for a guy in New York. 8x 21", 18x 8", 16x BG Neo10's and lots of Mundorf AMT's. I believe he's now taken the CAD files to various machine shops in the US and is in the process of having them manufactured. Materials are alu and acrylic and the project is about the cost of a new mid range Benz.
