Update: 07/02/2020
The parts arrived for the steering assembly today! 54 parts in here...
So I got to assembling the assembly (see what I did there?) All went well...
Until I realised one side had virtually no support and compromised the whole steering mech. You can see on the right hand side the bad planning decision I had made when initially coming up with this design...
Not to fear however! back into LDD to have a fiddle...
So after re-designing this part of the assembly the wheels still have the same range of movement, and I had the parts to make this modification too...
This was a vital part of the process, and I'm glad I found an error here, it means I was able to fix it before going too far... now to go back and examine the whole structure before going any further.
