buisness ? oh i wish, well maybe with a miracle

all along the turntable was just visable in my head, just not to the precision of a cad drawing, i set out clearly knowing what my favourite turntables were such as the gyro dec and j.c. verdier. Looking a ta turntable it is fairly easy to figure out why it is engineered that way, but i clearly wanted something fairly original using some good sound design principles. i started of with a few criteria such as it being a non suspended high mass design, a good cabinet maker friend of mine was working on some granite kitchen benches at a mansion and was lucky enough to give me some quality granite for next to nothing

then i had to face the engineering side of attatching a main beraing to the granite easily. after some thought it came to me as a revelation, i drilled 3 8mm holes in the granite(even that was hard work) and used a rose wood subplinth to easily mount the bearing this had the added bonus of allowing for a rigidly mounted tonearm assembly in which i could easily change the v.t.a. or the level by carefully adjusting the 3 screws under the platter

then came the platter my second criteria was for a low mass, high inertia design, i was originally going to have a thick 1 piece glass platter but the main bearing of the project seemed not up to the job of handling that weight

thats when i concieved the idea of using 4 rotaing weights in equalibrium (ala gyrodec style) i machined them up it worked superbly.

i machined up a turntable puck and used a diferent aproach cause of the layout of the platter i decided that the spindle be on the puck and it would mount down through the record and the whole in the platter

the motor was a no brainer, i used a similar design as the subplinth to isolate its vibration from the sub platter and i decided to mount the arm as rigidly to the plinth as i could by machining up a thick steel rod and bolting it to the plinth

my main design tool though was a stethoscope, i just simply tested the design on the fly listening to vibrations etc trying to isolate them, my amp died half way through building and without the added time for reflection it gave me the tt would be very different,

through the whole experience i learnt so much, like beowarld arm alignments practical vibration theories

now i cant wait to get started on my DIY arm :)

i will have some very high quality pics posted in the next few days
