I'd recommend something thicker, like the thread cutting oil that Colin mentioned. WD40 is probably going to be too light for this.

Get yourself some CT90 available from toolstation. Its good stuff i use it on steels and aluminiums when tapping and drilling. Works well for cobolt drills and hardox too.

Screwfix have an aerosol spray for £6.99, screwfix have the WD-40 brand of cutting fluid.

Ideally get some of this: https://www.ebay.co.uk/itm/PACK-OF-2...0AAOSwx1ReNKuH is a 2 bottle pack, but this is the stuff. This isnt a spray, so its much more economical than spraying generally.

With Robodojo coming back. I've been back working on my robots, I'm going to retire BOB 3 by putting it in full combat, give it a good beating. Right now I'm rebuilding BOB 1 as BOB 1 HD Remix, smaller, more compact, and more importantly, work.
The main problem right now is the locking bar for the lifter, it bends the bar a bit.
Just shows what a more powerful ESC can do.
Hah, seems like what you have there is a steel bar bender! Look forward to seeing new BOB. Shame to think of BOB3 getting "retired" though, always thought it was a bit of a silent assassin at Robodojo, maybe didn't look as flashy as some but always put on a good show!
Great to see a post from you Sean.
Technically the locking bar should stop the weapon from activating by accident and as
your weapon continues to operate with the bar in place it could fail a tech check.
Common sense says it is probably Okay on a slow moving lifter but to cure any doubt
you might use a stronger bar or mount it lower on the lifter blade to reduce the torque
force on the bar.
I moved the safety bar lower and it worked a bit, I think the camping pegs I was using are made of aluminum, 5mm thick. Will a steel bar be stronger?
Depends on the steel but in general, yes, they are stronger. I tend to use 10mm thick bolts as my locking bar.

Well, that was fun. 3 -2 is not a bad start to the year, even though we're in June now. I seem to have found the main reason why it hasn't been driving straight

Easy fix.
On a 4 wheel drive that would cause it not to drive straight for sure-On a 2 wheel drive it
would be virtually impossible to drive straight, I assume that wire is off one drive motor?.
It is.
