Another thing that helped my lith printing tremendously is one these...

I've just started printing with lith and I've noticed what you're describing. It's definitely not for those that are in a hurry... The first time I developed Ilford MGIV Warm Tone paper in lith, the prints took 25 minutes with fresh developer. Wouldn't you say, however, that it's real magic when the print starts appearing!
I have started the habit of making very detailed notes of my prints. Paper, exact dilution, temperature, exposure time, crop, enlarger column height, etc. It seems to be the only way I can get any sort of consistency with lith chemistry. But perhaps consistency is boring after all...?
I've gotten into the habit of keeping a bottle of single malt around, just in case I get bored or want an excuse for being cross-eyed while staring at the print. Currently Strathisla single malt is doing the honors, a very appropriate darkroom filter.

One of the little problems is that if the notes are made after a few prints have gone through the developer, next day you mix a new batch and the first print disappoints, particular if you are aiming for colour with high dilutions.

I got my safetorch from Tim also at the APUG Conference last year. I never did put any tape on mine and I've not noticed any fogging from it.
I have some Naccolith, but I like the Maco Superlith better. It seems (for me anyway) that all my lith prints came out brown when I used the Naccolith. That's not to say that brown was bad, it just wasn't what I was looking for. Although now that I think about it, I do have some negatives I recently took that might benefit from that look.
So, at first forgot to dilute the A+B mix. After a 4 1/2 mi. exposure, slid the print into the tray turned it, snatched it... too late! A total of 5 seconds in the developer.
Then, appropriately diluted, I kept getting ripples of uneven development for each of 4 successive 11 X 14 prints; garbage all. Worked fine the other day!
Since those were my last 11 X 14 sheets, I went with another negative, first go with lith for this one. Doing OK, but man, is it taking a long time; 40 minutes each! I realize that I'm into the third hour of the A+B mix... the developer's petering out on me. This is the second round of mix and I've been leaning over these trays for 5 hours now with no real keeper yet.
Time for a cold beer. Tomorrow's another day.
My normal exposing time is 20 seconds , with the apeture closed down two stops.
Normal development time is 3-4 min with novalith a b 1:8
my first thought is why a 4 1/2 min exposure?
Hi, Bob.
Well, I hope I'm on the right track...
My exposure was 4 1/2 min for that particular negative only b/c the original exposure (at f8, gr. 3) was 35 seconds. 4 1/2 minutes represented 3 stops over-exposure. Normally I do 2 stops. I tried 3 stops over with the Forte paper b/c the lighter tones were just not developing by the time the shadows were blocking. It did turn out better, but not nearly as good as the Ilford WT at 2 stops over.
Yesterday I worked on another negative that normally requires 5s under the enlarger; for lith, I exposed it 20s. Turned out nice.
Cheers.
Sugarcane Brandy no dilution.
Lagavulin 10:1
The first image here was exposed 1 stop over and the last 2 were exposed 3 stops over. Of the last 2, one was snatched a smidge late (I found myself being mesmerized by the infectious development and watching it fill in the details of the doors) and the second was snatched a smidge early. I can't decide which of the last 2 that I prefer....

Looks to me you have a handle on the process
I would try a 1:8 session just to speed up the dev process and with a second flash*could be a bare bulb on timer* you can control the contrast.
At 1:8 with Nova lith I get full black emergence around 3 min , never over 5 min.
Now you're talking technique!
Thanks for the advice.
