Patrick Tipton Posted December 19, 2020 Share Posted December 19, 2020 I am about finished with my hull repairs and starting to gear up to do the mechanicals. I ended up finding a set of nice 15" T24 tracks. They are in good shape - with a roller chain added for stability. I am not sure what I am going to do about the bands yet, but I want to start fixing the grousers. I have two issues in some grouser plates: bends and then torn off road pads. 1. I am guessing the grouser plates are hardened? I have probably 6 to 10 that are bent. My plan is to heat them and bend them back. Any experience out there? 2. Where the road pads are torn, my current plan is to weld a 1/4 or 5/16 tapped plate in the "hole" - then screw in a delrin road pad. I am open to thoughts or suggestions. Thanks, Patrick Quote Link to comment Share on other sites More sharing options...
M29C3284 Posted December 19, 2020 Share Posted December 19, 2020 I will have to check the drawings for the grouser, but I'm pretty sure that the grouser in not hardened because the drive lugs are. 1 Quote Link to comment Share on other sites More sharing options...

M29 Posted December 20, 2020 Share Posted December 20, 2020 Hi Pat the t15 grouser was hardened So I imagine yours will be as well. Drilling with standard drill bits is very slow. I found using a plasma to cut the holes was much faster. I used a cabide dremel bit to clean up the holes. I have posted in a couple threads more detail.

M29C3284 Posted January 1, 2021 Share Posted January 1, 2021 @Patrick Tipton I checked the drawing for the 15" grouser and I was wrong. The grousers are hardend, to 36-44 Rockwell C. But there is no mention of any specific type of steel alloy it just says "steel" as material. 1 Quote Link to comment Share on other sites More sharing options...
