MountainMan is very good at doing this type of work, and to be honest this is also a way for me to sharpen my cnc "programming" skills a bit. Using my normal tools I would have been able to make these parts much faster, but perhaps not quite as consistent part-part. Bandsaw about 1 or 2...

Don't misunderstand me - once you have everything figured out and your machine is set up correctly then it is an awesome piece of kit (obviously under the assumption that your CNC machine is of a reasonable build and quality)  :thumbs:  There is nothing more frustrating and irritating than...

Thanks guys! There are many interesting things about a CNC machine.  I will share some of my findings: 1.  Whatever you can make on a CNC machine, you can probably make without one as well.  Well - not too sure about you, but I can (teasing)  ;D 2.  It's often far slower to make a part on...

I had more errands to run today so while I did make some progress it wasn't as much as I would have hoped.  All good - tomorrow is another day! Photos: I drilled the sacrificial board on MountainMan and inserted some steel pins into these hole.  This allows me to exactly locate the ribs into...

Phew!  I finally have all 16 ribs cut out.  MountainMan does all the work, but it's still quite a challenge for me somehow and I am super tired of this step now  :boring: And just when you think the ribs are now done - NOPE!  They are only about 60% done.  I still need to flip them to machine...

Pleasure guys  :thumbs: Feel free to post here if you have any specific questions and I will do my best to help. Kind regards, Ian.

The main reason for the vacuum is to get the chips out of the the way of the cutter.  It's working hard enough cutting the wood - we don't want it working even harder because it needs to also recut the chips in the grooves. Secondary is that cutting creates a huge amount of chips - if I didn't...

Ok, hopefully this works!  I don't seem to be able to embed the videos here so you will have to click on the link. https://www.youtube.com/watch?v=dKRt0007uX0&t=12s https://www.youtube.com/watch?v=KD1ObErIpq0&t=21s Kind regards, Ian.

Ok Gents - I have no idea how else to do this...  You will need to click on the links below to see the videos  :whistler: What is very clear to me after doing these is that I absolutely suck at multi-tasking...  Trying to hold the phone in the left hand, and the vacuum in the right hand just...

:dop: Things are going a bit slowly for the time being, but not to worry.  I will be posting something interesting to look at shortly... Kind regards, Ian.

That build you linked to used normal thin Maple venereed side panels, with about 6mm thick veneered baffle. The inlay is Purple heart  :thumbs: Kind regards, Ian.

It's not 100% as simple as that because it depends on the architecture of the amplifier,  but its not too difficult. Start here: http://www.sengpielaudio.com/calculator-ohm.htm And then you can read a bit on my website here: http://paladinav.co.za/6-2/analog-electronics/power-supply-home/...

Here you go: Kind regards, Ian.

You won't have a y issues with the 5mm thick solid wood cladding. The general rule is to use less than 6mm thick so you are good to go! Satin or even matt black is very nice.  Waxed and buffed rosewood looks fantastic too. But when you put them together something fantastic happens.  Do you...

One more thing: every build you do will will be better than the previous one.  It's simply the acquiring of skills and lessons with time.  Don't be too hard on yourself for your first few builds.  You need to spend the time paying school fees before you can graduate. Like a good friend of mine...

Yes, wood is difficult to work with. That's what makes it a challange and in my opinion also what makes it exciting and interesting. Don't stress too much about what everyone says - do what you want and how you want to. So what if it doesn't look like a shop bought product or what other...

What's wrong? What is frustrating you exactly? If we can pin it down to specifics we could perhaps help you work through it. Kind regards, Ian.

^^^ You really need to learn how to use WinISD.  It will take you an hour to figure it out and then you can help yourself and perhaps learn something in the process  :dop: Kind regards, Ian.

Well, I have cut 10 of the 16 ribs so far.  Those FEW bits are pretty damn good!  I managed to cut 7 ribs on a single cutter before it became too worn and blunt.  In theory I should probably have only cut 6 but oh well - why not. I have a number of errands to run today so probably won't get too...

Not at all  :stop: I went to French Engineering Works (FEW) this morning to pick up a couple of new slot drills (milling cutters) for MountainMan.  Seeing as the Teak is 40mm thick I needed a bit of a longer than usual cutter.  This is what I found - a full 88mm long and beautifully made...
