Plinth for Garrard 401
« on: October 04, 2017, 09:54:02 PM »
Bought the 401 off the forum few months ago, came with a SME arm.  So I decided to use stuff readily available and do most of the build myself.  I have some handtools, but nothing fancy, no CNC etc. It would consist of three parts:
1.  Base: Mdf with aluminium frame, sand filled and arrow head spikes
2.  Turret: Mdf (3 layers),  aluminium layer 2mm thick, pine onto which the 401 is attached to.  Cavity filled with lead and non setting silicone.  Turret rests on base, not attached, but weighs enough not to move once positioned.
3.  Box to which tonearms are attached.  This also has a aluminium frame that fits over the frame of the base with very little play.  In between these I put some rubber mesh used to prevent carpets from slipping, and once pushed together there is no more play, but box and base are "decoupled".  The box is made of Mdf and have 3 compartments.  These were filled with a combo of bentonite, small rubber balls, small metal rods and silicate (glass) .....leftover stuff I use at work.

The tonearms will be the SME it came with (conventional position) and a Rega RB251 (from my Lenco built) at the back.  Final carts still to be decided.  Dustcover also reused from same.  Pics of some work so far:

Base:





Turret:



Box: (inside only) :whistler:



I had a table with resonant frequencies for different materials...can't seem to find it now :headbanger:

Excellent work Jan, looking very pretty. Any rumble?

Thx.  When standing next to the turntable I can hear some "mechanical" noise, but no rumble through the speakers (should have it serviced).  Tried to control vibrations in each of the 3 parts, and they are again separated from one another by rubber of sorts.  Will probably be selling 2 Lenco L75's (no tonearms) in near future as I'm going to stick with this for some time....and I am  a HUGE fan of the Lenco builds

Really looking nice Jan

Excellent workmanship and fine detail. Telling about the fine detail work you do every day  :2thumbs:
Styling of the plinth also a period match for the table itself.

Well done

Looks good!
And I agree with this: "Styling of the plinth also a period match for the table itself." - it struck me too,
could have been designed by Garrard in the UK at that time!

I love music - analog and digital. Even listening to the Blues makes me happy. During the day I coach and counsel, after hours I indulge in my second passion - listening to vinyl and restoring turntables. Some I keep, some I sell...

Stripped down my Boozhound DIY phono amp and removed all additional inputs, selectors for different arms etc.  Made a faceplate to fit in with the plinth, redid the power supply  :whistler:.  The silver switch on the front is to choose between 24V (from mains) or 18V from batteries.

Huh! I was wondering what the heck broke! Suddenly, I cannot see any images in the thread!

Same here. I could not upload pictures either. Hope they are not going to do a Photobucket  :(
