Bend Radii
I'm currently working on an endcap much like the ones included with the kitbot, but adapted to hold 20-20 extruded. My question pertains to bend radius annotation. The kitbot's bends are labeled as .62 r, but what does this mean? I've measured the radius of the actual bends to be about 1/16", so is this annotation a coefficient you put in front of the actual material thickness (1/8 by .62 is around a 1/16" bend)? I'm assuming so, but we know what assume does...

The bend radii is determined by the die used in the sheet-metal break. Our typical sizes are .032", .046", .062", etc... Andrew, Where is this misnotated? How sloppy of me. JV |

Re: Bend Radii
It's in the chassis part drawings pdf. Chassis Parts
No big problem, I just didn't quite understand what was meant, and thought I'd try to learn how such bends were labeled. By the way John, I was extremly impressed with the performance of the kit frame! I originally thought, like many others, that it would not hold up, but it has been the most reliable frame we have had to date! I'm looking to couple the best of both worlds in my modification: Multi-axis strength with the item extruded and it's fastener ease, with the incredible strength of the endcaps and the frame shape they foster.

Re: Bend Radii
John,
The error is in the notes section on each drawing. At least you were consistant - all of them indicate the bend radii is 0.62 (Where's a good checker when ya need one?) Sorry, couldn't resist. I know it's tough being both designer and checker. Mike |

Yeah, I just noticed that. Obviously our manufacturing guys weren't confused by the error.  "They knew what we meant." (Isn't it dangerous, when metal guys "know better" than the engineers?) JV |
