[Rhodes22-list] How to replace forward lower chainplates?

[Todd Tavares]

Michael,


You are going to have to cut a rectangular hole in the side wall of the
inner cabin liner to mount your reinforcing plate, and which you will bolt
the new chainplate tang to.

You can use a die grinder and a cut-off wheel to cut the old chainplate in
half. If you have a die grinder, you can find an arbor/mandrel and 3"
cutting wheels at an auto parts store or home improvement store..a Dremmel
tool won't have a large enough diameter cutting wheel. My local Advanced
Auto had a set which had the mandrel and three- 3" cut off wheels for less
than $20.
Then cut the chain just inboard of the bend. Pull the tab down from inside.
Go slow annd do not push too hard. Wear a face shield and respirator
See my crude sketch attached.
