Mantle, Tinkers Construct, and Tinkers Mechworks are all installed on my client, they are all the latest version compiled off of github. I also have the latest forge (10.13.0.1160) and am running minecraft 1.7.10. When I try to launch with tinkers mechworks I get this crash report. Near the bottom it says "TMechworks{1.7.10-DEV.3b2f91f} Tinkers' Mechworks Unloaded->Constructed->Errored"
