Hi, I recently began processing black and white film again and like to wait till I have 4 rolls of 35mm that fit in one of the larger tanks. All the sizes I have and have seen take the 4 reel but have a 3/4 inch+ space that lets the reels slosh around. Not good in my opinion. In the past I used a 110 or 16mm reel that filled it perfectly but I'm not finding those for sale anywhere. I once also coiled up a piece of stainless stell that worked fine also but alas can't seem to find any ss around. I'll figure something out but there must be a common solution that you folks have found and used-something found around the house every day etc...(posted 8197 days ago)Thanks up front, W
