JD2 Tube Bender Hydraulic Conversion

[Frizzle Fry]

Bought an air over hydraulic ram a while ago at HF with the intention of doing this. Finally took some time off other projects to get it done.

Manual tube bender (JD2 Model 32)


Decided to use existing parts as much as possible without making irreversible changes. This manual lever arm became the host for the ram. Here it is in the manual config (I ended up flipping it over later)


Ring templates/guides for plasma:


Cylinder support:


The cylinder assembly slides on over the existing lever arm and bolts on with 3 1/2" bolts. Holes are evenly spaced so two positions are available.


I plan to add a back-bone to the tube/ram support for increased capacity.


With spacers installed:
