I recently bought a bulk film loader off eBay. Not wanting to try good film in it I bought 25′ of Ilford Surveillance, P3 400 ASA. Assumed it was probably similar to HP5. I also bought plastic cartridges from the same place.
I filled up one cartridge wiht a 36 shot length. Used it and then tried loading it into my normal spiral tanks. Film base looks like polyester, very thin and no way would it ratchet into spirals old and new. Not having a stainless steel centre loader I used the Rondinax 35. I had been reluctant to use it at first thinking more ‘traditional’ means were the place to start.
I actually did get the 36 length in a tank, or so I thought. It had not gone into the spirals and only half was developed. Proved bulk loader was light tight though.
Next time it was a half, 36 shot length and into the Rondinax. First time loading it did not work which I think was my fault. Anyhow after putting film back in cartridge using dark bag I tried again and it seemed to go into the Rondinax fine.
In fact it has developed out OK. Again no light leaks, and also the complete length is processed. Obviously the centre loading process of the Rondinax seems to work with this very thin based film. As yet I have not scanned it but the negatives look fine.
A situation it seems where the Rondinax is superior to the traditional method. One tank spiral I used is an old Paterson, but the other is a new nylon used with the Spanish-made tanks that seemed to have replaced Paterson in availability.
Anyone else had this problem solved by a Rondinax?
