Converting an 8 x 10 camera into an 8 x 10 enlarger
Someone asked to see photographs of my project to convert my 8 x 10 Kodak 2D enlarger into an 8 x 10 enlarger so here are some images of it.
Image 1 shows the table base that sits on my darkroom countertop (and clamped down). Base is hinged for easy storage and vertical piece sits on the floor. The base is made out of 3/4" melamine surfaced partical board which has two thin masonite pieces on top that forms the track that the camera base sits/slides in.
Image 2 shows the 10 x 10 cold light head that sits on the back end of the base.
Image 3 shows the vertical panel with the 8 x 10 hole cut in it that slides in the track that the camera slides in. The vertical panel is pushed up against the front of the Cold Ligtht head.
Image 4 shows the front side of the panel that the camera is pushed up against. I made a little frame with a foam rubber seal that sort of seals up against the camera back (see image 5).
Image 5 shows a close up view of the frame that closes up against the camera back. It was a little tricky to figure out how to make the frame and get a reasonably good seal to the camera back.
More images to follow.
8 x 10 enlarger continued
Image 6 shows the 8 x 10 camera in placed with the front and rear beds down. Note that you need the rear bed to make this enlarger work because of the extension needed to do your enlargements. The camera bed sits on the base between the two pieces of masonite.
Image 7 shows the camera front and rear extended to about the normal working positions for enlarging an 8 x 10 negative up to about an 11 x 14 print. The camera back is extended to the back of the rear bed and pushed up against the vertical panel frame piece.
Image 8 shows my negative carrier - a simple 8 x 10 film holder with the center paper septum cut out to be just a little smaller than the film. The film holder is the type that has the removable wood/metal frame that holds the negative in place. The holder is just inserted into the camera back as you normally would.
Image 9 shows my home made adjustable easel mounted on the darkroom door. Note that the distance from the front of the base to the Darkroom door is probably less than 3'. The easel is built to accommodate 16 x 20 film and also with a couple of spacer blocks accommodate my 11 x 14 enlarging easel. Horizonal movement of the negative is done on this easel. Vertical movement of the negative is done with the vertical rise/fall of the camera front. General focusing of the image is done manually pushing the camera/vertical panel/cold light head forward and backward. Fine tuning of the focusing is done with the horizontal adjustement of the camera front.
This easel look like of complicated and it probably is (I got a little carried away). You can also probably use a piece of steel and magnets to hold your paper in place. I believe I saw such a steel unit with magnets on Freestyle Photo's website.
Image 10 shows the front of the camera with the 300 mm Rodenstock enlarging lens.
