Make the pipe 20mm longer, glue a smaller end cap inside about 10mm further inside from the outside lip and then use a heat gun to soften the 10mm over hang of the PVC pipe and then shape it over the end cap.
I have no idea if it'll work. Just making it up as I go along.

The idea with putting screws through the sides of the pipe is good, would make it strong I would think, but it's a lot of mucking around for a few mm's difference, is it really that important? _________________ ( •_•)

It is all looking very neat. I bet you will have a reliable bot, Trent. _________________ So even the rain that falls isn't actually going to fill our dams and our river systems

Thanx Phil.
Dewalt batt arrived today, and I will start to put together a pack when I can get my hands on some wire. Dewalt batt powering dewalt motors, it all makes sense
And in the background is just a small portion of the landscaping I'm doing this week in my backyard/front. My first week off work all year and I'm spending it workn my ass off. When I find some time/energy its back into bot buildn _________________ Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

What pack are you going to put together? Could you use the full 36v? How are you going to charge your batteries?
Your garden needs about 100 palm trees.
Edit; Just read that you will use Victors 883 and they take up to 24v. Please ignore the question about 36v. _________________ So even the rain that falls isn't actually going to fill our dams and our river systems

I was just having a read back through this A123 thread.....Phil posted this....
Some info posted on the RFL:
3532.6 in reply to 3532.4
The A123 cells require a very different charging voltage from regular LiPoly cells. LiPoly chargers charge at 4.2 V per cell, but the A123 cells require 3.6 V per cell. Connecting a regular LiPoly charger to a pack of A123 cells would destroy the pack from overvoltage. A 7S A123 pack will successfully charge using the settings for a 6S LiPoly pack, however.
CORRECT ME IF I AM WRONG
I would like to run 7 Cell A123 packs....I CAN charge this with my Triton set @ 6S LiPoly pack!!!! 25.2VOLTS!!

Bearing blocks/mounts are done. It took a while, but all the measures were correct and it all lines up great.

There are some good advantages, when using bushes.
the main one is that they are lighter than gearings.
the only real issue is that they have more friction on the rotating shaft.
But that can be over come with a good lubricant and don't let them become dry.
If you use a light machine oil or a low viscosity grease there isn't much of an issue at all. _________________ It's all about the destruction.

Thanx for the info Ajax! I'm going to try some graphite power for lubrication, it's the less messy of all the options I came up with.
