River Steel millemetri modifications

Thank you for posting this Mellons. I have a build planned with a few Ennebi parts that I'm fitting. Do you have a source to share for the gaskets?

[Mellons]

I ordered a few sets (wrong size) on ebay and eventually got the right ones. For crown v difficult to get exact thickness, i use slightly thicker but the compress over time- where are you based?

Hi Mellons. Great info. Newbie here & plan to mod the MM. (1) What is the actual OD/ID/thickness of the red gasket & black flat crown gasket? (2) To remove bezel is via the 3 side screws or just twist/pop like other normal models? Thank you.

Another member sent me these dimensions- Mille Metri O ring sizes 35mm ID x 39mm OD ( 2mm dia ) for red gaskets. Bezel comes off via 3 screws.. ill doivle check smaller gasket, IIr it should be 7mm od, 0.7mm thick ideally. I use 1mm gaskets and let them compress over time, easier to source. The other option is to take the gasket out of a spray can and trim down. The crown gasket will help to get 1000m wr.

I’ve used these in the River MM case 39 x 35 x 2mm od

And have these on order for the crown seal 7.1 x 3.7 x 1mm ( untested )

I think to get to the plexi seal you’ll need to remove the case back screws (6off) and the 6 screws that go through the case body

Big thank you Mellons & Simpsan for the info / assistance. Now I'll just have to wait for River's case to arrive.

You’re welcome, btw the small 7mm rubber washer came… good fit on the OD but I would maybe prefer the ID to be a tiny bit smaller…
IIRC My steel MM used the ‘spray can seal” and I’d say that is a little tighter.

BTW the o rings are I bought from AliX ( cheaper and larger quantity ) arrived before the ones I purchased locally through eBay… go figure!
