The metal block is drilled for the spindle in the centre, and also has a pair of staggered holes for the sprung plungers to make electrical contact between the underside of the deck rails and the two brass rings connected to the auto-reverser. In this photo you can see the pre-drilled holes in the Greenwood deck, which I had assumed are supposed to be for the plungers to pass through up to the rails. But as you can see they don't align. Then I saw that the metal block is actually supposed to run lengthwise along the bridge, so I can only guess that I am supposed to solder a wire to the bottom of each rail, feed it through the hole in the deck and then solder the other end to the top of the plunger, thus connecting the rail to the brass ring? It seems convoluted and full of potential for failure... Clearly I'm missing something, but the (frankly next to useless) instructions that come with the turntable kit make almost no mention of the block and plungers, other than that they fit together... If it makes you feel better….. my turntable has lost its memory Link to post Share on other sites More sharing options...
RMweb Premium Neal Ball Posted February 11, 2022 RMweb Premium Share Posted February 11, 2022 This is the feed to the deck - fixed to 2 bolts. Presumably they are in turn fixed to the rotary rings, but I can’t see them as they are under the deck I will try a photo under the turntable bridge next….

RMweb Premium Neal Ball Posted February 11, 2022 RMweb Premium Share Posted February 11, 2022 Try this it looks as if you can see the edge of the two rings…. Does the metal block sit under the bit of wood sticking out this side? Link to post Share on other sites More sharing options...

RMweb Gold Graham T Posted February 11, 2022 Author RMweb Gold Share Posted February 11, 2022 I thought I should give him a chance, so I've emailed Mike Greenwood asking him how the plungers are supposed to align with the rails.

RMweb Gold Graham T Posted February 11, 2022 Author RMweb Gold Share Posted February 11, 2022 (edited) I'd been trying to put everything together without the spindle going through the upper level of the turntable deck, but it was becoming just too difficult to make sure everything aligned properly, so I've bitten the bullet and drilled through the deck. Luckily everything does indeed still align after my wanton bodgery, and I can patch up the top of the deck at the end of the build. It will need weathering anyway. I'll also trim down the square mounting plate when I get around to installing the table in the baseboard. Must remember to drop the spindle back down when all the work is finished though!

MrWolf Posted February 11, 2022 Share Posted February 11, 2022 You need to start out with a scrap one of these: Seriously though,, I'm thinking of getting a Dapol turntable and making something that works as I have before and then figuring out how to automate it. I used carbon brush pickups originally intended for high tension magnetos. I am now wishing I still had my sketches or the original turntable. 3 Link to post Share on other sites More sharing options...

MrWolf Posted February 11, 2022 Share Posted February 11, 2022 It's a Garrard deck, very similar to the scrap one I robbed for parts of the drive mechanism and spindle bearing to make a railway turntable several decades ago. They did use the Garrard in the 1950s version of the Dansette 2 1 Link to post Share on other sites More sharing options...
