kentmere 100/400 in xtol? were do I start
trying to find some film to use in bulk so put in an order at freestyle for couple different single rolls. one of them happened to be kentmere 400 and 100 and my problem now is I can't seem to find any rough starting times for developing this stuff in xtol.
massive dev chart is empty and I'm not having much lucky looking around anywere else. any ideas of some rough starting times?
If there's nothing out there, or if nobody else has any development times, then try the times listed for D76. More often than not, they're quite close, but you'll need to test and fine tune.
I don't know how much help it is, but I ordered a bulk of Kentmere 400, and in this crappy Sprint Developer we use at school, it seemed to develop a little dense with published times for HP5+. I'm getting some Ilfosol 3 to try it...
Actually, there were published times on the box of film, but I threw it away. The Massive DEvelopment Chart has times listed (though no for xtol).
As Anon wrote, development times for XTOL and D-76 are remarkably close for most films. If you have no other data, this would make for a very good starting point. Any adjustments will likely be quite small.
I ended up just doing 1:7 dilution and let it sit for about an hour to hour 1/2 or so with around 30 seconds initial agitation and then once at around half hour I shook it around for a couple more seconds. came out dense and haven't tried printing them yet to see how it would look as I figured might as well put this roll up for experimentation. though I do have this strange band on the bottom of the film near the edge with little developement while the rest of it came out nice and dark. not sure what happened there as this was the section on the bottom of the tank and so I know it was exposed to developer and not an undefill situation.

If you compare the development times for HP5+ and Kentmere 400, it seems that at 20'C they recommend on average an extra 2 to 2.5 minutes of development time for Kentmere versus HP5+.
I am shooting a roll of Kentmere 400 which I intend to develop in XTOL, I'll develop for approximately 11 minutes in XTOL 1:1 versus the recommended 8.5 minutes for HP5+
Vincent: Sprint Developer is not so crappy. Look under the hood, it is probably closer to Ilfosol than you could guess.

Sprint does have times published for the Kentmere films time chart, and the time for the 400 is longer vs. that of HP-5 so going in that direction as TimeShare says makes sense for a starting point. I'm surprised that Ilford hasn't put up a time for xtol as yet. I'm also surprised they make it so hard to get from the Ilford site to the Kentmere site, well, not so hard but not so clear either.
Why do students always hate on the stuff the school provides? Hmm. Just a rhetorical question.
digital truth list the development time for hp5 as 10 mins.

What temp did you develop at?
Sprint isn't a crappy developer. I used it for 3 years.
looking at a few combos it looks like the times for kentmere are very close to the times for delta 400

Reason: more info
I haven't tried this myself, but I did find this (and this thread) while Googling for experiences with Kentmere 400 pushed to 800:
Although it's in Swedish, you'll find some development times for Kodak XTOL and Kentmere 400, but _not_ for Kentmere 100
"Konc" (short for "koncentrat") means stock (ie, no dilution).
