Tri, I couldn't remember the details of that great 11x14 you have so I had to use the Zone VI for my model.
Jorge, I am a glutton for punishment!
Jim, thanks again for the suggestion of getting a +1 diopter for this lens. I put it on the 8x10 and shot it at 16,32, and 64. All of the negs came out great. The F-64 is amazingly sharp. I will print them as soon as I can and post the results. The F-16 was a close up of a stump and image holds up well. I didn't shoot it wide open yet. I think it is a 7.7. I need to do that. Can't scan 8x10 negs or I would. Now that the camera is officially done I can get to work making images with it and printing. Maybe I'll shoot a paper neg tomorrow and post the results. Need to read up on that one.

Wide open is what I'm most curious about. Just rate your RC cheapo paper about asa 1 with a #1/2 printing filter dropped in the waterhous slot and soup in some Dektol.

Jim I'll give it a try tomorrow night. The one stop that I have is marked #30. It seems to be about F-16. This is a Euroscop #4 and it is about 16" focal length on the 11x14. I'm guessing it to be about F 7.7 wide open. No cheapo RC only fiber and no filters other than my lee filters. I have a Packard to attach to the front of the lens with a nifty filter slot built in. Should I use a yellow? Thanks.
Jim
A yellow only affects variable contrast paper. If it's VC then a yellow filter lowers the contrast which is needed with paper negs. I've got a Euryscop 5 that I may have to try this on.

Jim, I'm in business because I have some VC 11x14. The Arista which is the old Forte paper so I'm good to go. Can't wait! Thanks.
Jim
It seems counterintuitive that a yellow filter would decrease contrast. After all, it's what I use to increase contrast with film. But I guess paper's spectral response is different enough from pan film to make it work the other way. Otherwise why else would grade 0 or 1 filters be yellow?
VC papers have two types of sensitiivity in the emulsion -- low contrast green and high contrast blue. The yellow filters blocks high contrast blue light, thus lowering contrast.
Sandy
photo paper is blue sensitive which is why a red or orange safe light can be used when printing in a darkroom, can't do that with film
WOW, Really beautiful work, Jim! One to certainly be proud of!!!
