Morning All!
So yesterday I sat down to give the dining room table a bit of a tidy-up.
It was going well, but then I got distracted.
But!
It was a good distraction and some good came out of it.
So the thing that has really been fighting me in this build has been the rear drive. After extending the wheel base, by moving the rear wheel assembly back 20mm the drive shaft was too short.

Initially I thought about cutting the existing drive shaft and extending it, but when I did it - it just felt like it wasn't going to work.
So next I ordered a metal drive shaft from Ali Express - about £5 inc postage, but only to find when it got here that they'd sent me four very nice carbon fibre wheel hub (not a drive shaft). Sadly I couldn't see a use for them and started the refund process. However, now I knew better what I was looking for, I found the same sort of thing on ebay and ordered one of them but this time for £9.
When that arrived I discovered that it was designed for a 5mm drive shaft from the gear box, and the WPL is 3mm.
Okay, ordered some adapters.
Meanwhile I took the wheels to the guy at my local model shop and asked him if he could get rid of them for me - I don't know any one in the local r/c car community - and told him to see if he could sell them for about £10 (on Ali Express they're £18). So if that works out - I got a refund for the initial purchase and the vendor said 'keep the wheels', so if I get a tenner for them it covers the cost of the drive shaft off ebay, and someone gets a set of carbon fibre wheels for cheap, and hopefully the chap in the shop makes a couple of quid on them.
The adapters arrived, I worked out how to fit them with shims so everything was snug and then discovered that the shaft was too big to fit the shaft out of the gear box - it was actually rubbing against the motor casing - and I was back to square one!
I was really p!ssed off at this point, and walked away from it for a day ...
... and then came yesterday and clearing up.
I had the dremel out with a cutting wheel, so I cut some brass tubing and cleaned it up, fitted it to the stub of the original drive shaft.
This isn't the one I have been working on ...

... but the blue line shows you where I cut the part.
This is the brass tube sitting on the stub, with a nylon spacer to sit in the tub, along with a load of superglue and baking soda, and eventually I'll put a pin through it as well.

Assembled. Initially the problem had been that the stub felt loose in the tube, after monkeying about with the other drive shaft I was switched on to the idea of using shim - metal spacers - so I added some shims around the stub to make it fit better.

More pinning needed, but much happier.
In place on the truck. Hopefully this will never get the sort of hammer that rock-crawlers get - hence why they have metal parts as after-sales/upgrade items, so this should do the job for just running it about.

Completing that made my morning.
I also moved on to assembling the cab.



Thanks for looking in.
