Awesome, thanks, looks like you’re having fun! It’s very important to check out the General notes from Week 8 as they all apply to you but in addition to this:
In terms of how you use the hologram as a template for forming (as you’re doing in the first 30s or so of the video):
- You don’t want to use the hologram of your part in the assembly as the guide during fabricating the part itself. You should orient this hologram so that it is as close to planar as possible (or in whatever orientation makes it easy to fabricate). It should also be oriented in your work area (e.g. near your clamp / vice / jig)
- This process could work OK if you can keep the rod fixed at one end using a vice or a clamp. The idea here is you want to be able to work on individual bends in isolation. If you keep one end of the part fixed, it should be possible to bend the piece (the red line) to one bend at a time until it matches the hologram and repeat. The challenge is going to be fabricating the variable radius of the bend - so for this reason I think it would be better suited to styrene, or you need to rationalize your design to a single radius of a conduit bender.
- Second option would be to work with a jig during bending - e.g. to make something that can help you produce these variable radii smoothly rather than just fudging it by hand. In this case you still want to do one bend at a time and check this with the hologram before moving on to the next bend. You probably need a technique to mark on the length of material where a bend starts and finishes.
