I was just going to order a new grip ring to get as a spare as I have 3 players that use them, only to find all the parts sites have it discontinued... Along with the m-holder the grip ring seems to be the legacy LD replacement part. another blow to the lifespan of LD.... ![Crying or Very Sad :cry:](./images/smilies/icon_cry.gif)

I should have put must of the time they don't fail, and it does look to be the same material on other players. so it doesn't surprise me. I did some measuring and found the height to be just about equal to my thinnest feeler gauge, at 0.010". The inside diameter is about 1-7/16" and the outside is 1-3/4". It does seem hard to find anything at that thickness , there are some things that come close. there is soling tape for shoes that has almost similar texture but is too thick . The circle design rubber mat is sold for flooring but on a much larger scale, there is also some tape for handrails that looks the same, it looks good but it might be to thick possibly? here is what they have to order. Also there are Anti-Slip tapes, they are various materials most with a sandpaper like surface, maybe too abrasive 3M makes a tape that sort of resembles the white rings

I may actually still have an OEM one but since those parts famously suck I’m not afraid of trying something else. I’m less worried about this than almost any other aspect of the Laserdisc part supply Götterdämmerung. It is literally just a rubber sticker. There must be hundreds of alternatives. haha agreed, a bit of a challenge but most likely the least of our worries....... Bring on better 3D printing!

Since my DVL-90 is slipping badly and my attempts to clean it have failed, I'm going to go ahead and start trying out alternatives, today I picked some plasti dip at the auto parts store along with some steel tubing to use to make a punch for sheet material.
The one option is try the idea Publius has and paint on a ring of plasti dip, I'll try some samples with a brush first and see how it looks. they do have a spray can but I think its a wide spray like paint and I'm afraid it will go all over the place.
Other option is cutting a ring out of an anti slip material, I ordered a strip of the 3m anti slip tape which I can hopefully cut out with the tubing I got. The tape I got is 23 mil which is about twice the thickness of the oem ring, though its still .023 of an inch.
Depending on time and how things go I might end up testing both methods on the player, first thing will be testing the plasti dip since I'm not familiar with it. Then hopefully over the next week I can make up the punch tool, I ordered the tape last night so it will be a few days before I get it.
Of course any progress I'll post here.
As for the M-holder, I'd be really interested if it would be possible to plaster mold one for aluminum casting, I don't having any casting experience but I'd love to try, or at least pass it off to someone who can.

I think you’d have to be really good at casting to do an M-Holder in aluminum. Getting the bubbles out would be very tricky. Also, I don’t think the “axles” would be all that tough even if they looked it. This is kinda below the “minimum resolution” of cast alloys. If a company wanted to make something like that out of alloy they’d use powdered metal.
To me the best way to make the part is IP. This will run like $2000 probably at least but come on, some of the bread guys here drop on cables and unwatchable movies...I’d be very surprised if we couldn’t find the $$$ if someone presented a solid plan.
The next best way I can think of is hand fabrication out of various materials. I’m thinking epoxy, styrene, brass. The bulk of the part in one marierial with brass axles. These would take a long time to make but it’s my backup plan if we never get real plastic parts again. On a case by case basis I have no doubt I can make them.
The third option is maybe a hybrid of the two. If we use brass or some other strong material for the axles the rest of the part is less critical so maybe that could be cast in epoxy or 3D printed or whatever and the the axels would come later.
If anyone wants to lend me an M-Holder, PM me. I really don’t want to spend time extracting one...
Also, how many M Holders are there and what models use them? I’m assuming this is for the Gamma Turn decks like 704 and 99?
As for the plastidip, just mask the areas you don’t want to hit. The plus of plastidip is that it’s self leveling so spray if possible and let dry flat. It will almost certainly peel off without a problem so you should be able to get a few attempts to perfect it.

Ok so I painted on the plasti-dip, I made a few different attempts to get it how I liked, which was trying to get an even coat but also with some texture to it, ended up with putting a single coat smooth, then going back and lightly "sponging" with the brush while it was tacky.
After a few hours of drying it actually leveled out quite a bit, maybe not perfect but the wasn't what I was going for. not sure how it would compare to spray but brushed on it seemed to come out fine.
Fired up the player and....it works! So far just brief testing, but I did a few side changes and stops and it did really well, Once though it did slip on a spin up an fail to play, but that particular disc was giving me trouble before and I think the label is dirty.
Otherwise very smooth, quick side change and stops dead right away, the question is if it will hold up in the long term. I'm impressed so far, wasn't so sure of a first attempt but...so far so good...
