Hi ! I own an old Laborator 100 4x5 enlarger. I plan to bolt it to the wall in order to suppress the baseboard, helping position my 4 bladed easel. Of course, the Uniwal Durst made for this purpose is as scarce as hen's teeth, so I'm left with "DIY if you want one". I've seen some plans, thought about aligning the negative stage with the baseboard, but if one of you, guys, have done the "thing" I would appreciate your help before putting the saw and hammer into use ! Thanks for your help !
