do not waste Hard disk computers, can be used for DIY tonearm.
Many HD which had been unused and I noticed there was something that could be used for our project is Bearing.
if we look at HD function to read the data on the disk rotating at 7200 rpm must be right, no mistakes and always accurate, just as we are doing now with our PC.
it takes part bearing of HD is excellent, should not be loose or wobbly.
why we do not try to recycle ... garbage ... go green IT.
unused HD:
The HD is already open.
I think this very good bearing...compact ,strongly and acurate ... but this motor have magnet inside.
I think this no matter because Schroerder's TA used magnet too
or our can take arm bearing :
and drawing model DIY TA HD:
model used the HD arm bearing
Model used HD motor
just discus only

Used arm bearing from HD
dimension draw
make a pivot pole. HD bearing is used as a buffer for horizontal movement.
Bearing of pivot rod use usual. our can use a part of tamiya or other. for vertical movement.

suwaned,
The arm in the photo uses an HD bearing for the horizontal pivot and CD carrier bushings for the vertical. It works OK, but I prefer modern ceramic hybrid bearings.
Your 401 plinth in the other thread is beautiful. Congratulations.

hello dtut,
I'm glad you shared DIY the HD bearing tonearm, very nice ... that has been working with the good. have a nice DIY TA
good idea used the modern ceramic hybrid bearings is good. low friction, our will looking for that for vertical bearing.
I have tried looking for.
Thank you for an appreciation for my new plinth.
my plinth have not already finishing. but only for tested because my the tonearm wire to short for new base. That DIY HD bearing tonearm too.

This is pivot , my first project I had made separate :

Very detailed work gentlemen.
But I'm wondering why Not simply adopt the Clever and V Good bearing that Nanook used/developed for his $2.19 Arm?
I tried both and I find the additional security of the hard disk motors reassuring and the sound slightly more 'solid' too. The ability of any of the usual linear trackers to become derailed rather bugs me too in spite of the way they sound.
Our 'spider' model overcomes this objection.
As an aside, if you want maximum freedom in the bearings you should use them upside down as they spin in the other direction and all the ones I have used have been much freer in that direction. Can't say I've noticed any difference in performance though

hi Bare,
My dream to get a long tonearm, as I have already tried to modify the techincs arm to replace the aluminum pipe to the wood. i have a problem and I think must to made DIY TA.
In my first work this, later i wanted to make a simple to use HD bearing arm which I think is very good because there is no movement, but I have difficulty when making the pivot for vertical movement. So I tried to make a little complex.
sorry i do not understand about the Clever and V Good bearing, next i will learn about that.
regards
ed
I have already upload video , how are the pivot spinning?
It is stability

how long distance of pivot to spindel ideal?
After the pivot was completed. I have to determine long distance of P to S.
I choose a long distance aproximal 16.5", because i think with the long arm can get little tracking error / more linier path of circle.
And what is the ideal? I don't know. Because how long the distance of arm used when to made the vinyl. It is must same. That complicated for accepted many kind of the records.

The cutter has a servo driven tangential arm. It were ideal to have the same at playback, but the biggest problem here is to follow the groove that has variable pitch. There is an inherent offset error that has to be corrected by a servo or by mechanical means.Because how long the distance of arm used when to made the vinyl. It is must same.
Ed, I'm really impressed with the work on your arm..
I'm working on a project called 3R. Reclaim-Rework-Relisten
Pic one is a JVC drop in.. Pic 2 is Consonance Droplet.
Also reusing the Spindle, motor and platter from a Yamaha YP450 to use with a single arm..
Going to try out some plinths made with great Canadian maple
For me finding good ARMs at a good price is a dilemma.. Yamaha parts are pretty good but original arm is not that good..
Can you make me an arm to try out? I can send Pm to discuss? Price etc?

i have experience to founded good arm like your , i looking for good arm is over price for me. small budget.. and do it for My hobby.
and soo i starting explored to how build of the tonearm by self. 1 year i have do it.
Actualy i'm not confidence to myself for share about the DIY TA. but i 'm willing to share my experience and hope all friends can give me feedback and advice to me.
Thank you very much to you for appreciation for my DIY TA. this supported for me. I make it for my self and i have not desire to commercial.
i have just shared. please don' say price.....
I hope all friends not consider high expectation for me because i'm an amateur and not an expert. I just curious and hobby.

i think i was wrong to be a dentist.
and my buddy "Joel" , i apologize, i'm not professional, but i will share my experience and help what i can do it for you, and our can discus about the DIY a long Tonearm.
Hi again Ed and thanks for all of your TA details buddy..
The distance between us is a little far but maybe a trade at some point.. Plinth in exchange for a tonearm maybe Just hobby ideas..
Your Dentist skills must be Awesome!
The paint on my table is done by the same guy who applied the Piano finish on all the Energy Veritas speakers.. The table is sprayed but not made into piano finish but Planning to make one without the grooves then he can do piano..
Talk to you later.. Outdoor project is waiting for me..
Keep posting.. Really enjoy it..
Here is idea I had for arm board for Rb300 threaded style arm mounts.. The center piece is solid and user drill for the arm.. The bottom washer compresses against the main piece..
