New Deck finished and on test !

[Kanders1]

Hi all,

Just like to share my latest 'Man Shed' project. The "K2" DD turntable. Designed and built in the last few months and now finally spinning the vinyl and sounding very sweet indeed...!! unbiased as i am of course. :eyebrows:

So for those are interested, its a laminated Aluminium and acrylic construction, total of 50mm thick weighing in at around 10kg. 5mm clear for the lower layer which acts as a light guide for the mood lighting :drool: then 20mm black acrylic makes the base layer then a 5mm aluminium layer that the motor mounts too. then another 20mm black layer of acrylic. All the electrics are in a separate control box of a similar laminated construction. The connections are via two separate leads, one for the motor the other for lighting and strobe and connected using small aircraft panel connectors so that it can be separated easily. The whole unit is mounted via turned acrylic spikes that are adjustable.
The arm is a Rega RB303 (rewired) and sits on an adjustable VTA mount. Sure V15 Vx with V15 VMR stylus.
The Donner TT was a 1974 Hitachi PS38, some new components were required, and some parts were discarded. The LED lights are controlled via a 12v touch on/off dimmer switch.

thanks for looking.. any questions comments welcome...

Looks very striking and beautifully built Karl. Good job!

[Firebottle]

Oh wow. Cracking job there Karl, well done.
:thumbsup:

[topoxforddoc]

Looks a beaut. I'm sure it sounds great too.

[Spider]

Awesome job, unique look, great job and beautiful design.
how did you cut and polish the parts for the plinth?

[M6NTL]

That's a thing of absolute beauty - can't wait to see your lid..!!.. ;-)

Looks very stylish, professional and individual - :respect:

[Kanders1]

All, thank you for the kind words..! :)
The plinth was bolted together then.. cut with jig saw, then routed to a template. Then.. the sanding bench sander 60 grit..then 240 then by hand with wet and dry 500 800 1000 1200 1500 2000 2500 then G3 cutting compound. Brasso to finish..
as for the lid.. materials arrived today... ��

Bet it was quite the oar deal :eyebrows: Very nice.

:stalks: :)

Wow !!!!! Beautiful looking turntable.

[Ali Tait]

Nice job!

[Si74]

That looks superb!

[Dubster68]

Very nice:D

[macvisual]

wOw Karl, that's amazing......! You've got great talents!! With the blind reflections on the platter it actually looks as if the platter is carbon fibre......Cool.

Great work Sir! Respect!

Thanks to all that have said positive comments, just one word that makes me smile.. the shape.. was inspired by my guitar plectrum.. but on completion it looks like an iron :lol:
Thanks again...:cool:

Karl

[struth]

Thought it was a boat. Nevver mind it looks super

[Kanders1]

Thanks Grant... Guessed that from your previous comment :) Boat is good, better than an Iron I think...??

[Qwin]

Great skills, looks more like CNC machining, than the hand and basic tools method you used, good job.

[Audio Al]

Very nice

You could call it " Boaty McBoatface " :D

[RothwellAudio]

It looks great but I don't see any sign of a suspension system. It would be nice to see more people with the skills and talent that you obviously have tackle suspended designs. Many of the well-known suspended turntables such as Sondeks, Ariston, etc. were good but would be greatly enhanced by having a much heavier sub-chassis. I can understand why commercial producers aiming at a mid-market audience would shy away from massive construction but it would be ideal for a DIY-er who doesn't have to worry about the logistics of transportation.
Anyway, just a thought. It does look great though.

Andrew, thanks...and interesting view, and I do understand what you are saying. I did look this, my first deck the K-1 �� Was based on two isolated plinths one granite the other wood. It was okay but far to fussy and quite frankly not worth the effort in making and the setting up, the goal is to listen to my records and hear the music.
Personally, as a mechanical engineer I've learned one common factor when it comes to mechanisms....simple is efficient.. there are so many variables involved in playing a vinyl record as we are all aware that I feel reducing the number of those variables must be a plus. So in this case I went for simple "mass" and lots of it lol Acrylic and some aluminium weighing in at nearly 10kg. The deck shelf is bolted directly to the house brickwork. The control box removes any transformer vibes and the rest is all shielded.
I have checked the motor/deck when it's running and there is all but zero vibration or rumble through to the platter. The vinyl sits on heavy rubber platter that in turn sits on a felt layer.
For me.. the sound that it produces far exceeds my expectations for what this deck cost to build. And I love the way it looks unbiased as I am...��
Cheers,
Karl

[struth]

The srm deck I had was the same and sounded great

Karlthats a thing of beauty Karl. My Denon Dp80 came with a heavy rubber mat that I believe has a different material inside it. Personally it doesn't sound as good as the copper mat I use, if you get the chance to try a copper or gunmetal mat give it a try. I assume the control box is separate from the plinth, what feet are you using?

[jandl100]

That looks awesome. :thumbsup: :respect:

I prefer seeing pics on the thread rather than having to click on a thumbnail ...

Paul, Yes the control box is totally independent, and the feet on the deck are 25mm Perspex turned to a spike and 6mm thread for level adjustment. The control box has 16mm spikes, also adjustable to match the deck height if required.

Karl
