Make 4x6 prints with 6x7 negatives

[67II]

Hi - new to this forum and just started my darkroom - so the learning begins. I have made postcards on 4x6 Ilford paper using 35mm negatives and a 50mm lens. I'd like to make the same size postcards (or very close) from my 120 film - 6x7 negatives. My lens for the 6x7 negatives is 105mm. My enlarger is a 23cII.
I fiddled around trying to make that work today but it may not be possible with a 105mm lens?

Appreciate your guidance/recommendations. My 1'st grader niece loves my analog postcards!

Thanks

According to this should be OK. Look here for the manual. 90mm is standard According to Beseler. Make sure the condensers are positioned correctly

Thanks - I'll check it out.

It should work, you just have to remember that a 4x6" print from 6x7 (negative is about 2.25 x 2.75") is only about 2x magnification. This means that for your 105mm lens, the negative-to-lens distance will be about 150mm, and the lens-to-paper distance will be about 300mm. This means the enlarger head may be higher, but the lens is racked further out, than you are used to from printing 4x6 from 35mm negatives.

Keep in mind that a 6x7 negative doesn't match a 4x6 print in the format ratio, as does a 3:2 35 mm negative. So you're going to have to crop to fill the paper or leave white borders on the paper if you wish to print the whole negative image.

Welcome to Photrio! What issue did you run into while trying to make it work? As said above by @reddesert, it's mostly a matter of whether the focus bellows will rack out far enough. I don't doubt it will since your use case isn't particularly extreme.
