Spong No3 and grind retention

#1: Post by **RickO88** » March 25th, 2022, 6:46 am

I have recently acquired a Spong No3 after reading Spong Coffee Mills: A Grinder for the 23rd Century and Spong 3 Restoration!
After grinding a few successful cups I have decided to have the hopper powder coated in white. On disassembly I have found a fair amount of coffee sticking to the burr. Will the flax oil as mentioned in the second link help to stop this? Any ideas welcome and thanks.

you might want to PM the original poster from the first link (@DJR) as he seems to understand the spong quite well but I'm sure the poster from the second link (@coffeenaut) would be a good resource too. from what I understand the flaxseed oil takes a long time to cure and certainly it could provide some sort of non-stick coating if you're willing to put in the time needed to cure it.

Thanks for the reply. I've not heard from the other posters. I'm getting some flaxseed oil and will report my results.

I have given up on the Spong grinder for espresso. The link: Spong Coffee Mills: A Grinder for the 23rd Century is doing a disservice to people looking for a grinder. After using my number 3 for a month or so it is not very suitable for espresso; the grind is not uniform with many different sized particles. Perhaps for pour over...
