Default First ever DIY TT

Hello you fine gentlemen. Been stalking the site for a while, now posting my very first DIY project.

Been doing it on basis of a old Technics SL1600. Kept the motor + platter and bearing, ditched the rest.

Its a "Sandwich" layer type TT, with bottom layer, made of 15mm solid Aluminium, middle layer from 55mm PEHD (High Density Poly Ethylene), top layer 1,5mm stainless steel. Made the powersupply outside the TT, and speed adjustment + 33/45 selector and On/Off where changed to better switches/potentiometers.
Recapped the motor control curcuit, and kept it inside the TT. FItted it with a sl1200 mk3d tonearm.

All is handmade, on a friends mill/lathe. Made a lotta mistakes during the process, but learned a ton of stuff :-] This DIY HiFi bug is catching on .

Just restored an ancient RIAA, from Dali, but thats another story.

Heres the pics, somewhat in cronological order.

And I do apologise, for the lack of my English writing skills :-]

Motor mount, with oilbath milled out :

Motor mount + feet + suspension muck up:

Cork sheets between layers :

Adaptor for Tonearm, due to stupid mistake (made the hole too big).

First quick assembly of the layers, still no powersupply nor tonearm.

Power supply manufatured (mdf + acrylic. Rewired everything) Tonearm installed - ready to go

All set up, tweaked and ajusted. And you can see the home made 876 gram record clamp allso :-]

Thnx for looking. Any ideas, suggestions, comments are greatly appreciated.

Well done!

I'm about to do something similar, so I'm wondering how you determined the cut-out for the platter in the top plate?

@ Miniwatt : I had the spindle center to the center of the tonearm calculated. So i knew the distance, then i measured the circumference (dunno if thats the word) of platter and tonearm base ( added 2,5 mm to both) - and just milled it out.
