that is really excellent work. well done!

[bernte_one]

thanks

grip is adjustable, only untighten the screw change position and fix it again
screw can also be changed by a fast lock clamp
but is not necessary if you find the right postion once

[Davor]

Now tell us how to do that ourselves

[Gold Finger]

That looks great bernte_one.

Do you think the plastic pipe would become more rigid if the round profile was flattened into an elliptical shape?

[greylourie]

Now tell us how to do that ourselves

Yes, please do. A nice pictorial guide would be good.

NVM I had some machined up.

Was it very expensive to have done?

[Sean_Goddard]

Not really. £25 each but I had to supply the CNC files (was done on a HAAS 5 axis mill). Sadly I don't have any pictures and the handles all went on custom beach machines I built for people.

I incorporated ENTER, UP, & DOWN waterproof switches in the grip (ENTER on top as thumb switch). I was going to incorporate an LCD on top of the grip but didn't bother.

Switches were APEM micro IP67 and had to be epoxied in place as there was no way to get at the screws.

Here's my compactable design. 25mm aluminium tube@ $10/m (700mm), and a $5 bamboo composite broom handle. The brackets and armrest are cut from 2.5mm (?) walled, 100mm sewer pipe, which is heated and shaped with a rework gun. The handle is foldable and the armrest also folds down. A strip of thin rubber is glued in the lower half of the extension bracket to enable a good grip on the smaller lower shaft. Gutter bolts and wingnuts are used for extension bracket and handle. A self-tapping screw clamps the armrest-set right it still allows armrest to be twisted down for storage without adjustment,(not shown here-added later). I am using 3x18650 batteries, with an inbuilt charge controller(mounted alongside battery box), and a 1w solar panel mounted on a bicycle phone bracket. This bracket I will also make from pvc in the future.

Well done. Have to admit I cheated and bought my last stem cheap on eBay. Much nicer being 3 peace packs really small.
