The first hiccup I experienced was when one of the captive nuts dislodged inside a pipe while assembling the frame. Luckily it was one of the ported caps, so I could access the nut and managed to fasten the bolt as designed. With the frame holes drilled as per the dxf file in github, the PVC pipes are slightly bent around each other, but the frame is nice and stable.
Other snags: the hole in the top platform, through which the drive shaft passes, can be at least 1 inch diameter. I originally made it only slightly larger than 22mm, but the outer pipe touched the wood once assembled, making the one arm difficult to turn. Disassembling, fixing and reassembling took a good portion of the afternoon.
Another thing: the printed parts break easily. I'm sure the second assembly will go much easier, but I have broken some parts. Nothing that I could not fix with a bit of glue, though.
The progress so far:
Getting the wires through the pipes is a pain afterwards. Try and put a draw string in before you assemble everything.
ReplyDeleteAlso glue the little captive nuts in place. There's a 100% chance they will come loose and fall into the pipe when you loosen the platforms.
