Hi all,

I saw Alex's wonderful video about making one's own wet plate holder from an 8x10 film holder.



I am about to embark upon making such a holder, but I intend to use a 4x5 holder to hold quarter-plate-size glass/aluminum.

Just wondering if there are any extra precautions to take since I'll be working with a much smaller holder, or if anyone has any practical advice in general.

I got me three new-ish Fidelity holders, they use a metal center septum instead of wood; I'm hoping by the time I'm done, I'll have one good, usable holder.

Thanks in advance.
