Floppy drive motor

[BluesMagoos]

The floppy drive motor seems to work fine and has some decent power. I thought it would be easy to stop with my finger, not so. I’m using 4 AA Nimh.
My econo setup, pioneer platter, Grado.

Very nice! Congrats!

looking good. do you have any hints that you want to drop for either the motor or the ladegaard?

very nice.. more pics of the floppy driver motor??

Managed to get a floppy motor too spinning constant. But have to lathe a pulley with the right diameters, was'nt able to regulate the speed electronically. Took a motor with the least play of bearing, combined bronze/ball bearing btw.

The floppy drive is still working as it should and the pitch sounds correct to my ears. The record anvil weighs 445 grams, I’m thinking about changing to a lighter gripper type.
I’m going to try a 5VDC wall transformer made by Interex that puts out 2000ma. The battery power hasn’t been a problem but I’m always thinking about the charge state.

I’ve abandoned the Paul Ladegaard air bearing tonearm in favor of the unipivot. My thoughts on the Ladegarrd would be tonearm wires. The wires can be a real pain to deal with. I think the low compliance cart is the better choice for the Ladegaard arm.

The unipivot makes me smile, it’s so simplistic in design and plays superbly. I’m still in need of a cueing mechanism.
A big thanks to Carlo Morsiani for answering a few questions and for the information he’s posted on this forum about his unipivot tonearm

For now I’m satisfied with my econo tt, it is what it is……

The board is actually two parts connected with a ribbon. It's folded over and taped to the underside of the motor for now.

My thoughts are the same about a lineair tracking arm:needs a stiff cantilever suspension to avoid "tilting" of cantilever before the whole carriage is moving. A soft suspended cantilever will bend considerately, then creates an even greater error compared to a unipivot/cardanic arm.
(I am planning on a roller bearing lineair arm, but first busy with re-installing my diy arm, did some maintenance on bearings & added new carbon arm tube, and it sounds promising with stethoscope allready)

I am now also switching over to belt drive, discovered a worn bearing in my old modded Akai DD.
Made a MDF base for the belt drive, the former DD had a marble sheet base, rubber suspended. It resonated like hell.

Maybe not that exotic this time but we will see how it sounds:

Here is the diy arm on the old DD with marble base. It then had still the old aluminium tube. (Takes some time to load)
