Advice please 🙏

Thank you so much.It all becomes clear.I have looked at the build pages so much It becomes difficult to work out, which is which.
I will get on to Armour tech.To see if they can provide it. Teamwork makes the dream work thank you

[Clive Armitage]

Found it thank you

Clive, the linear bearing will probably damage the softer aluminum barrel, unless your going to rework the barrel.
You may find it works for a while, but the hardened ball bearings will cut groves into the barrel. If you were to machine the barrel and fit a steel sleeve you might find it lasts longer. Linear bearings are usually used on hardened shafts.
I've used sticky red grease which seems to serve the purpose, repositioning the servo improves the line of operation too, see my recent post.
Just a thought.

Thank you very much and very sound advice.I will see about getting the correct bush .
Every project seems to create another project. I will revisit your thread this evening.

Hi John I have now read your post and will be following some of your suggestions thank you , also going to experiment with some lead weights tomorrow and a couple of ideas around the screwdrive gun elevation system.

[Clive Armitage]

Following reading John's post about improving the barrel movement. I've carried out a non scientific experiment. To find the amount of weight for balance. I've never understood physics and maths very well but it worked.
Now to find a suitable piece of lead

[John Clarke]

Don't forget wind resistance
And gold bars size wise are heavier than lead.

Or platinum.
Even better iridium

I haven't seen a basic build of the top end of the engine, but you won't go wrong looking at Phil Woodard's Chieftain build from around page 70.
