We got a customer enquiry:
I have just finished restoring a second hand RP (classic) to go with my original machine..
I wonder if you have an info sheet on linking 2 of them for training?
Rowperfect link bar spec
Stainless steel flat bar – Two lengths each one to be 1 meter long ñ 15mm wide ñ 5 mm thick (as close to as you can source)
Drill Three holes: 9 mm diameter: one at midpoint [for a joining bolt and nut ]
One hole at each end 10mm from end 9 mm diameter [these go onto the RP main frame threaded rod 8 mm that extend downwards]
Add [purchase from a hardware store]
4 x Wingnuts 13mm
1x and 25mm M8 bolt and 13mm nylock nut for the midpoint.
The same design can be used for RP3 or RP classic machines.
