Someone asked me to draw up the grab rail on my Jota so they could have one made by an engineering shop.
It proved a little more involved than I first thought, and I ended up making a 3D render of it before I could create coherent side and plan views. It's ended up as a 4 x A4 pages. The drawing scale is 2:1 so should print half size. Obviously the 3D picture is not to scale. It's just whatever size would fit on the page.
I've attached the 4-page pdf file here. If it works, and you can review the document, please let me know if I've done anything profoundly stupid. If any of you guys work in an engineering workshop that makes stuff out of bent pipe, any comments on how I could improve the drawings for the blokes on the workshop floor would be appreciated.
The version I've drawn is the short type that fits a bike with vertical shocks. I presume the long type that fits bikes with the laid forward shocks just needs a longer rail at the bottom. If someone could give me an accurate measurement of the distance between the mounting points on the long version, I can include a note on the drawing.
If anyone wants to turn one of these grab rails into a luggage rack, just weld whatever rack size/shape you need on the back end. But you might want to choose a thicker walled tube or add some stiffening around the rear mounting point for added strength.
If it ends up being a useful document. I'll put it in the library section.
Cheers,
Cam
