I’ve applied about four coats of tung oil “finish” (a mix of tung oil, most likely polymerized, and varnish) to the cherry on the 4×5 insert.
I’ll let this cure a while, then tape off the film holder recess and spray the rest with lacquer. The underside of the insert will be sprayed flat black. Ground glass retain clips (Tansu screen corners) are on order – once the glass is installed, this insert is finished! I’m pleased with how this project is turning out. It should prove very functional.
Next task: Create some form of tripod mount for the camera. This will be either a round base plate mounted to the existing spider on the camera’s underside, or a mahogany “roundel”, made to fit the hole in the camera’s base.
