FUJIMOTO LUCKY 90M-D Enlarger and CAMBO SC (4x5) Angle Locking Tool

The support column and head of the LUCKY 90M-D Enlarger are connected with a U1/4-inch screw.
The screws on the CAMBO SC (4x5) rails are U3/8-inch.
Adapters to convert U3/8-inch to U1/4-inch are commercially available as tripod accessories.
By combining this accessory with the LUCKY 90M-D Enlarger, the CAMBO SC (4x5), and the Intrepid 4x5 Enlarger Kit, you can build a 4x5 enlarger.
However, there was an issue with the difficulty of fixing the mounting angle of the CAMBO SC (4x5).
This tool is an accessory designed to resolve that issue.

Since there are various types of CAMBO SC, it may not be compatible with your specific model.
It is not designed for wall projection, so it does not support that function.
I think the screws from the LUCKY 90M-S Enlarger are the same type, so they should work. However, the 90M-S is lighter in weight. Because of this, I think it’s less well-balanced than the 90M-D.
