I agree it would be more to drool over however I am in the process of building a model drilling rig for my father as a retirement gift and will need to design some sort of transmission.
On a real rig they use a 6 speed diesel transmission similer to a large trucks and I think the t-5 would be perfect in its simplicity since I already know how they work on cars.
I dont need the (Beautifully machined) case or anything. Just the measurement; gear info, distance between centers ecetera would be so useful to me and im sure others. Who has not thought at one time how useful/neat a gearbox would be behind their model engines.
Suprised no one else has asked! Definitly post when you upload them to the downloads section. Thanks.
