Diy tt v1.1

[HoopsOnToast]

Thought I would start a new thread.

So far, I now have a Rega RB300 arm

And the Motor, Platter/Bearing and PSU from a Sony TTS-3000 courtesy of Adam :^ (pics to add in a few days or so)

Idea is to keep it cheap and simple

Idea V1.1:

Basically a 2mm aluminium top plate to mount the bearing, motor and tonearm. I can get these made at work which helps.

There will be a bottom plate too with a plywood cylinder in between for the motor/bearing and tonearm.

I have also put in a decorative plinth to go around it, pure looks.

Nice Rob. whats the graphic/CAD package you are using there?

 

[HoopsOnToast]

SolidWorks :^

 

[Vinyl Art]

Cheers, I shall have a look at that. I have been looking fro something a bit easier and frankly, better, than Google Sketchup.

 

[HoopsOnToast]

Its quite expensive, and the rendering part (that I used) is extra IIRC

Yea just saw that on their web page, oh well, my search continues. Will bang out of your DIY thread. Might start up a new one on simple CAD packages though. :^

Any comments on the Pioneer arm? (with a better headshell)

Could I better it for around £100, or would it be better spending the extra later on a cartridge?

EDIT: now found a Rega RB300 arm so will use that :^

 

[HoopsOnToast]

Well the Sony bits are here, and the arm sorted, so I am going to get the plans for the top plate done tonight.

One thing I have seen is the difference in the mounting distance with the RB300.

http://www.vinylengine.com/library/rega/rb300.shtml

Rega say 222mm but other say 219.5mm for perfect baerwald alignment.

Will the cart choice influence this? I have no idea what I will go for yet.

And again, many thanks to Adam :^

I would say go for 222 or you could make a slotted arm board or a movable round arm board with an off centre hole that way you can experiment with the two positions.

 

[HoopsOnToast]

Thats an idea, just make a slot instead of a hole :^

Rega use an alignment which is pretty much Stevenson, basically optimized for the best result at the inner grooves. You can get baerwald with some cartridges (the mounting is further forward in the head shell, at the front of the slots), Stevenson has a shorter overhang so the cartridge tends to sit more in the middle of the headshell.

All above is with the standard mounting distance.

Go for slot!

My advice would always be to go for an SME mounting, as you can buy/make adaptors from SME to most others, but trying to get an SME mounting arm into a Rega hole is a bit of a challenge.

Sweet graphics.

Is there any particular reason why you're coupling the bearing/motor to the arm via the top-plate? I would have thought de-coupling might have been a better way of avoiding noise from the former getting to the arm/cart...

 

[HoopsOnToast]

Only doing it that way as that's how it was in the original design:

[paulf-2007]

allow for a 12" arm and then make one later, its not that difficult.

Double Post...

Finally been getting on with some stuff. Had a busy few weeks and been doing some other CAD work so got round to modelling the bits properly today:

Getting there, once these are done, I can do the final design properly. Main bits to do are the mounting plate and a rough version of the RB300 arm :nerves:
