I recently acquired a Reprex
No. 2 [No. 1] proof press. While everything on this Reprex appears to be in excellent shape, it is in fact missing the drive gear on it’s form roller. The original manual I have specifies that there should only be one drive gear, and the part number for this gear is D48 on the Reprex parts list.
Assuming I won’t be able to locate a replacement part off another press, it looks like I’ll need to have one made. I need to determine proper specs for the gear, since the gear rack and roller cores differ from those on the Vandercooks I have access to. Unlike many of the Vandercooks I’ve seen, the gear rack for the inking system on the Reprex appears to have the same tooth pattern as the gear racks for the entire carriage. What I know at this point is that the diameter or my roller cores are 0.5″ and the roller diameters are 2.5″. There’s an image below of the gear rack for the missing drive gear for measurement purposes.
I’m hoping some other Reprex owners may be able to offer some insight on replacing this drive gear in whatever way possible. I’m thinking I should be able to have a new gear machined if I can supply a gear diameter and correct number of teeth to correlate with the gear rack on the press. Or perhaps the gear/rack is a standardized part that may be readily available?
I’d greatly appreciate any and all info anyone may be able to share. I need to (hopefully!) get this press up and running for a visiting artist by mid-March, so I’m trying to tackle it as soon as possible.
