After following the R2D2 build made by Victor Franco, I decided that I'd copy this simple straight forward option of controlling R5's dome (29.09.14) A fellow UK Builder also has a similar design to control his R2 unit.
Unfortunately myself & R5 won't be able to attend this weekends planned event. So with no further events this year, he'll be getting ready to be stored away till the New Year and be ready for 2015's events. Got a few things to work on though, dome motorisation, 'Bad Motivator' system, maybe even some sounds?!?!? So a lot of things to keep me busy. So till then......
Re-assembled all the components into
the inner foot frame. I used loctite on the bolts that hold the motor in place.
Then after locating the drive belt, re-fitted the rear wheel, along with its
upgraded spacers and washers. Looks and feels so much better :-).
Lastly I fitted a black front caster. It needs to be lubricated
as isn't very free moving. Before assembling I did weigh the frame and it is slightly lighter..... lol :D R5's outer feet casters were white and were only used as I had swapped them over from the the feet internals that allowed R5 to be pushed around on. This one has now been changed to a black one, need to buy another one, so I hope, they will not be as visible.
On stripping down the feet internals, I noticed that there was some brass 'dust' residue on the bush's. On closer inspection I realised that I had not machine turned the diameters on the ends that make contact with the wheel bearing face and they were rubbing on the outer diameter face.
So in work, I machined both pairs down in size.
I needed to make up to new washers, as was easier than trying to modify them.
Old washer, far right of picture, for size comparison.
This afternoon I removed the internal motor frame from the shell, with the intention of stripping it apart to carrying out the weight reduction process as for frame no.1, only to find it wouldn't come apart? On looking inside I found one of the motor bolts had come loose! I managed to get the internal frame out and found that the other two bolts were loose.these do have barbed locking washers, but I think I may have to apply some loctite thread lock!
