The epoxy is deep enough to secure the lead in the hole. Nothing more. I used the green (fantastically expensive) stuff because I ran out of 5-min.

Yes, it's heavier.

No, the shot is not completely infused with resin.

No, it's not "tuned to a different frequency", well, not intentionally anyway, I'm saying that tongue-in-cheek because a certain British TT manufacturer claims that for the 3 identical feet on the bottom of their plinths, because as each supports a different amount of weight, they all resonate at a different freq. ... LOL

Back 1-1/2 decades ago the group that started out as a diy turntable group but morphed into three different manufacturers, Teres, Galibier and RedPoint. In that group it was generally considered that shot pockets of #9 lead shot should be prepared in one of two ways; 1) dry and loose or 2) loose but filled with thin viscosity silicon lube. The argument in favor of the silicon lube was that it served to induce the lead shot to interact with vibes passing through. But it was necessary to make the pocket liquid proof. Which was easy if your material was acrylic or some other resin.

Since then I've used loose and dry #9 lead shot pockets in various plinth projects. To some observable benefit, imho.

The shot-filled clear acrylic platters look completely awesome.

Sorry, the first time I read this I (incorrectly) saw "piles" (as in, 'two piles of dirt') instead of the plural of ply, which you spelled correctly. Lol

he he :-)
What do you guys think of a platter made of copper? Wouldn't it be even better than that space grade adamantium you were discussing before?

Sure it would!

But it would probably be expensive enough to just scrap the idea and get a Mk3.

You can see the electronics out of the way in order to get the heat on the bearing cap. I used a bit of aluminum foil as a heat shield just to be sure, but didn't get a photo of it.

The old ball, interestingly the ball is interference fit into the bearing well and it makes an oil seal, the bottom was dry, the top was wet. Neat! It needs to be bonked out with a chopstick or something non-maring, from the top.

I see no reason to use heat-release thread sealant (loctite) on the bearing cap, so you can see the regular blue used here.

Remember to clean the gunk off the bearing well before re-assembly (shown here before cleaning) and add a few drops of oil.

This is starting to look pretty good! Yes, I'm missing the Technics badge in the front right. No, I don't remember where I put it...

Mounting the arm, step one. Measure the specified distance from the spindle and mark. (I don't remember what the specific distance was, it was in the manual...)

Arm mounting jig. This is one of the reasons I have a complete love for Graham tonearms, they are so ridiculously easy to mount, align, and use. This jig is placed over the spindle as such and then ;

You simply place the arm in the rough hole and on the jig, then mark the armboard under the mounting holes. Easy!

Drill them out and secure the arm. That's it. Insanely simple. Thank you Bob Graham.
