DIY 8x10 (or larger) Enlarger Chassis

[Ethan]

Ethan, good idea on the Neg Stretcher!

Glennview camera makes similar http://www.glennview.com/index.htm

I use 2 Calumet 8X10 glassless Neg Stretchers that are delicate in usage

I have huge Saltzman Neg Stretcher, 5X7 and 8X10 very sturdy

MANY here insist on double glass AN on both or not

I have huge 12X12 AN glass to glass in a set made for nothing I can find

THEY will object to glassless

If you need something let me know by PM

My last negative carrier was inspired by his, using springs and tiny holes punched in the negative corners. For this I'm wanting to avoid punching holes. Hopefully it will work, but if not I can go back to the older design.

Very impressive!! Look at the Zone VI 8x10 carrier called something like "out flat" I don't remember the exact name these work quite well.

Do you have one of those? I’ve seen it mentioned several times, but haven’t come across any images on the internet

I tested several lenses at f11 for sharpness for my horizontal enlarger yesterday, from 240 to 360mm, and the 240mm had the darkest corners.

I'm wondering if your corners will be so dark you will want a workaround.

Only way to tell is to make an enlargement. Have you done it yet?

My best 8X10 enlarger was partly DIY by the last owner, a very influential Pro that gave me a large print he made on it

1 of 100's sold for real money

He and I proudly use a 240mm Nikon enlarger lens, it covers fine

Study this http://store.khbphotografix.com/EL-N...ives-Used.html

as I immediately gave the $600 print to my daughter the size eludes me

at least 16X20, OP was limited by basement height

No enlargements yet… hopefully soon. Which 240mm did you test?

Only a taking lens: a Sironar-SE f5.6, I skipped to test the process lens Fujinon-A.

I hope to use my 300 f4.5 Industar-37, it went from good at f8 to excellent at f11.

The 12" Velostigmat was not useful at f11. Nor the 300mm Fujinon-W.

My testing was done on the Linhof rail camera I intend to use as an enlarger against some lamps.

It might be some of the lenses was damaged or misaligned.

Congratulations on finishing the project! I'm really impressed.

Are you going to paint the shiny metal black?

Probably not black, since that doesn't really fit the aesthetic I want. Likely a matte grey.

Looking at the rodagon G 240mm, there might be some fall off towards the edges, but that could be caused by the reflection coming from the table to my eyes. I'll know for certain once I'm able to run some test prints

I compared my 300mm Rodagon (non-G) to my 240mm Schneider Componon-S at 2x enlargement (16x20).
With the grain magnifier, the 300mm demonstrates the exact same grain sharpness and clarity from center to edge.
With the grain magnifier, the 240mm demonstrates some loss of sharpness near the corners.

Examining the prints together, with my eye about 1 foot from the corners of the prints, I can't tell the difference. I'd need a magnifier to see if there is any difference. Even with a 8x loupe, it is hard to tell any difference.

Thanks for testing! I've also got a rodagon 300 non g, but am hoping the 240 will work, as the ceilings in my basement where I eventually hope to have the darkroom aren't very tall.
