Yes totally agree ! and if I remember correctly it was a reason I started my own thread - to share my learning experience so I will keep true to this and add in my limited experience in this terrific hobby

Today I was adding in some details to the drive sprockets and fixing details:















The drive and transmission has been the most time sapping process to date. as I am not of a engineering background this has taken maybe far longer than it should have. Although there are a few very amazing scratch builds on this forum there wasn't enough details to help me make a knowledgeable decision in my build. So this is what I have gone with :

24v motors https://gimsonrobotics.co.uk/categor...d-24v-versions

1:2 reduction bevel gears to make right angle transition

Linear and thrust bearing on the internal shaft + locking nut

Tapered roller bearing in the hub/sprocket to sort out both axial and radial loads?

I will post some pics of the setup this week to illustrate

more details to follow
