Hi All,

Has anyone used the ring of the soda / beer can to make a nose bearing.
The thought struck me so I worked on it.
Cut the ring from the cap.
Cut off as much required for required clearance distance from motor stick.
Flatten ends ( the ring is a tube actually)
With nose pliers curl the ends around a drill bit ( thickness according to prop shaft dia)

Found that the weight is pretty low too. Less than a SO bearing.
Also has better stiffness to take more rubber tension as it is a tube and not a sheet.

Can be attached to MS with thread and adhesive and downthrust can be adjusted as required easily as it is a semi circle.
Some pic attached

Hi all,

Some more pics.
First one showing size comparison
And the dia of the ring

Need to see how to split the rear end to make the prop removeable

Drinking more beer surely a good way to loose your bearings while making more prop bearings !!!!!!

Cheers

How on earth did you so perfectly wrap those ends around the drill bit?  Very neat idea!

Hi Glen,

Once the ends are flattened well the aluminium is pliable enough to wrap around a mandrel.
Nose pliers like the ones jewellers use with a very sharp tip and round jaws will make it easier.
A little patience to gradually shape it around the mandrel as if it done in a hurry the aluminium could tear too.

Not something very hi tech --- indoor modeller I'm sure have a naturally high craftsmenship skill especially those in the F1D category and similar ultra light weight categories. Scale modellers too -- accuracy and finish of scale models needs a good eye and skill too.

Creative, like it.

Does it have pigtail, so you can switch props, or not yet?  Smiley

cheers to the beers! (-:

Hi Fitnezz,

No pig tail yet. Need to work on that. will have make a hole and then split in half.
Will try it out.
Very hot weather now in my place -- peak of summer -- around 35 deg -- ideal chilled beer weather. Best season to collect enough caps from the local bars.

Cheers

Splitting this can be tricky I guess. It might be way more difficult than normal MW pigtail. But who cares, another reason to buy a six-pack again Grin

Hi all,

Got down to try and make a bearing where props are removeable.

Made a hole with sharp tool
Twisted the end 90 deg to make hole face the front end
Then split the rear end to make it a removable type bearing.
A 0.7 mm Ikara shaft and a thinner guitar wire prop shaft could be fitted to it and there was free movement.
Pics attached
Short Video of the free movement will be uploaded to my Foldnation channel on youtube also.

Seems a workable bearing
