The Truce TT was an evolution of Peters desire to build a cheapo tt,
and my compulsive mass sentiment.http://www.diyhifisupply.com/node/452http://www.diyhifisupply.com/node/652

Not really partial to the inverted bearing design as it makes the oil
resevoir nearly impossible, and due to the fact that this particular
brg has tightish clearances running grease as is usually required in
an inverted design was not desireable, (IMHO).
Not visable in the picture is a center hub that incorporates a
resessed well that acts as an oil resevoir.
There is a layer of reinforced rubber between the hub and the 1.5"
base plinth. The cutting block is sandwiched between the bearing hub
and the plinth, nodding my hat towards constrained layer damping. The
arm mount which was intended to have the set screws mounted in the
back for cosmetic reasons mounts the rb300 style threaded stub on a
length of material that is fitted closely to the hub to allow arm
removal and addition height offset for the uk audio mods arm.
Watching Peter work on TT's has allowed me to tailor this particular
design to make it easier for him to service and adjust the arm without
having to acces the bottom of the deck.
Peter originally wanted to mount an armboard on the butcher block as
well as add spikes to the base. I felt compelled to over do it.
Number wise I believe this one is the fifth construction.
I also like the idea of adding mass to the end of the moment arm, that
being the arm mount at the end of the plinth. Adding mass to that
point reduces the resonant frequency. In my own experience this quiets
the feedback loop/hum that occurs at louder volume levels. This is
also the first forray into a non-empire motor driven deck, breaking
the reliance on parts that are rapidly gaining in price. I am very
grateful to Peter for the experience I have had building tt's. It has
been quite rewarding and I wouldn't have been able to perservere
without his confidence, approval, and generosity.
