Help Wanted. BM20 Plus top lip dimensions
Hi
Is there anyone out there with a BM20 plus model that could tell me the diameter of the top lip?
I have a component to modify to fit an older model that has a bigger diameter.

How are you planning to modify it?
If you have access to a welder, could you cut it and add two lugs that would take a bolt?

Hi Mashbag
I am going to modify the clamp there are two flat bits of metal on the mechanism that need to be longer for the clamp to have a bigger closing diamter to accomadate the old BM.

Scary imo. 'cos if the size is much bigger it just won't fit (seat) even then' cos it's a formed, stiffened circle!

Not really scary i just need to make the clamp accommodate around 10mm more diameter.
The inside of all BM20 are the same so no worry's about sealing etc.
Just wish I could get confirmation of the outside diameter of the BM20 Plus.

Re: Help Wanted. BM20 Plus top lip dimensions
The diameter of the BM20 Plus is not relevant. Focus on fitting the lid to the BM20 you have. Pre 2015? I noticed a slightly different lid design when the 2015 controller was released. They should be a bit clearer with their description as I read it as ‘the fermentation lid is compatible with previous BM/BM Plus’. The quality of these units is so high they last years if treated with respect. I’d therefore expect compatibility to be maintained.

I agree.I’d therefore expect compatibility to be maintained.

How does knowing this measurement help with the mod?
Re: Help Wanted. BM20 Plus top lip dimensions
Compatible it maybe.
but the clamp is too small for a pre BM20 Plus models.
so modification of the clamp is the cheapest, easiest route to take.
The difference is so small I did not realise there was an issue until I tried to pull the clamp down. and it would not compress shut.
Contacted Speidel and they confirmed that this accessory does not fit pre BM20 plus models.
Knowing the measurement of a plus model will tell what size to make clamp mechanism I can take a guess but would prefer to real diameter to aid my maths for the new parts.

Re: Help Wanted. BM20 Plus top lip dimensions
I’m guessing it matches the fermentation lid With a v-clamp, which I assume is supplied with the lid, there should be some way to get it to fit. Thinner seal perhaps? Or even without the seal?

I am with you now. You are going to replace the link between the ring and the handle.
Maths makes perfect sense, trail and error could be tiresome. Be aware some of those mechanisms will bend surprisingly easily if you get heavy handed

Now all sorted with a modified clamp and a brew bubbling away nicely
