I have had good results in half frame with 100TMax and PanF+, both in Beutler. As said above, just a personal preference.

You should really compare the full specs of the NiMH, the substituted LiPo, and the charger used, to be technically sure. And the load specs, if possible. A 24V charger for NiMH should be cheap, if a...

24 V is 24 V. However also check capacity of the NiMH to make sure it is in the ballpark of 6000 mAh. NiMH should be larger and heavier than Li-polymer for the same capacity. This aside, it should...

Well, Beutler is not a two-bath, although some people use it that way. The classic Beutler uses two concentrated solutions that are mixed and diluted just before use, as a single bath. That is how I...

I have used quite a lot of TMX in Beutler with excellent results. Could never get quality negs from TMX with D76. Delta 100 should work very well in Beutler!

I am late to the thread, but my favorite for 100TMax is Beutler. One of the best film-developer combinations IMHO.

Fog may be a bigger issue than development time, especially with more sensitive films. I have developed 10-yr-expired film with standard times in D76 1:1, obtaining acceptable images.

Taking fully apart the Rondinax 35 to get at the knife is not hard. There are a few screws to take out on the "dry side", that is all. The device was made to be easy to maintain.

Colophony resin is used to give grip to bows' strings in instruments, such as violin or cello. AFAIK it is harmless. You can give it away to a musical school.
