One possible issue, you still have the more flexible deck plate. I serviced a G99 a few weeks ago and couldn't believe how much more 'solid' it's build was.

The bearing clamp will mitigate some of the flexibility in the deck plate, but I've already taken care of the flexibility issue by preparing a second top plate that is full is marine resin. Believe me there is NO flex in that top plate. The resin adds an additional 1lb in weight to the top plate and massively improves the contact surface area. Trust me I've given lots of thought to this build. Just out of interest, Dave, what problems do you think may arise from the additional flexibity in the '75 top plate? I'm always interested to hear theories, ideas etc I might be able to do a little more tweaking.

Yep , it would make things a little simpler if it fits over the original body . Don't know which would be best for SQ though .

I was under the impression that you had to separate two plastic parts of the cartridge.
The bit that has the mounting grooves on, and the part containing the generator.

I think that the theory is similar to this - http://www.lencoheaven.net/forum/index.php?topic=5044.0

Nice find Kevin, looks like I'm taking some scalpal blades home tonight then. I've never done surgery on a cartridge body before.

Tonights Update - The Reference Lenco Pt XX - Putting the jigsaw back together again.
OK, so I turned upto work this morning and found that I had a nice package waiting for me containing my new bearing and it's matching base plate. I also had the pleasure to find a new Snake wood body for my Shure M55E cartridge and in second package hiding behind the first. The new bearing is quite meaty and pretty hefty when compared to it's original older brother the lathe work on this product is second to none. It just feels right. The same can be said for the matching base bearing base plate. Fitting both the base plate and the new bearing will take ~5 minutes and is an extremely easy process. It is a tight fight and a little wiggling around has to be done before things are back in place but once fitted it looks extremely pleasing to the eye. The Lenco has been inactive for quite some time and in that period various mods and upgrades have been installed and all have been documented over the last few updates. The main differences are that I have x3 platter rings on the second platter, I have a denon 103M installed, and the new bearing and base plate. So, it's going to be impossible to see how each little tweak has impacted the '75 so I think It's probably better to describe the whole thing as a "package" when I write up my findings in the future. The Lenco isn't without it's problems at the moment. It did have ground loop hum which I've solved but I think I've knocked a suspension spring out of place as the motor is now vibrating and making some noise whilst previously it was silent. The deck still needs some tweaking and TBH has only been roughly setup. I just wanted to get the thing playing . Spinning the double platter on the new bearing has been quite fun the platter now takes ages to stop and just seems to rotate forever.
The bearing and base plate.

See what i mean about a tight fight.

My favourite MM cart, my old M55E, this has been through some mods over the last year and started off as a complete punt from eBay for £13! Here it is pimped in a snakewood wooden body. Remove the old plastic body is a piece of cake and took exactly 60 seconds. I was shocked to see that the main body of the Shure cartridge is very thinly glued into the old plastic body and TBH probably rattles around like a silly bugger. Just out of interest it would be extremely easy to rebody the shure in the old plastic body if needed. Fitting the cartridge into the new wooden body is a piece of cake, just push it in. It's an extremely tight fit and I honestly think nothing else needs to be done with regards securing the cart in place. My own concern is the mounting bolts. You'll need some extremely thin mounting bolts to mount this onto a headshell. I think I might just have to widen the mounting holes by an extra mm or so. I'll be trying this tomorrow. Personally I can't wait.

So the '75 is back together and now I'm just going to enjoy it over the holiday, learn it's sonic characteristics. I'll fine tune the deck's setup and get rid of the motor vibration. So far it's sounds better than it ever has. Now I just have to find a piece of thick steel to further stiffen the bearing connection to the top plate, but that's another mod for another day.
