hi guys back online now, just had a test drive and all is good. thor did everything it was told so next test will be drive and weapon together. the bench tests of the hammer have suprised me, there is no delay what so ever and its fast, very fast. wont be testing tell next saturday as im of to scotland for a break, but i shall video it and pass it round if anyone want to see it

Any chance you could bring some nice weather with you - its been windy and raining here for too long :sad:
Well Thor IS the thunder god...
Good job on getting Thor back Jason!
jason has done a lot of work to thor and its about time too. thor is now totally rebuilt yet again with a hammer back to pheumatics. he has moddled the system on thz and is now fine tuning it. thor is really back and looking good.
Any particular reason for all the switching between electric and pneumatic?
Its interesting comparing an electric axe/hammer vs a pneumatic one.
Although an electric hammer sounds a good deal simpler, in practice it can be rather more troublesome.
Due to the power levels necessary for a decent heavyweight electric hammer, one has to take rather more care with it in use, compared with a pneumatic setup.
The motor has to have a clutch to protect it from excessive torque shocks (I believe Jason managed to break the bond between the shaft and armature on a Perm). The clutch has to be set just right - too tight and you risk damaging the motor, too loose and you lose power.
When firing the hammer in a fight one has to be constantly mindful not to keep the fire button down too long or not to fire it the wrong way, to avoid overheating the motor.
The Perm PMG-080 motors, due to their small size, are relatively easy to overheat. If you get the Neodymium magnets too hot (even high temp Neos can only take around 100 °C), they will permanently lose their strength, which will cause the motor to lose torque and run even hotter...
A pneumatic system, although more complex, doesnt need to be treated carefully. You wont damage anything by doing the wrong things.

Correction - it seems that typical high-temp neos used in motors can take 150 to 200 °C. Still quite low.
The Somarium Cobalt magnets used in Astros can take around 300 °C.
what john said
i really had 2 problems with electric thor, first the clutch needed adjusting all the time. that may be down to it needing running in more and i went though 4 perm motors to get to the uk camps and felt it would have never as been as powerful or realiable as a pnumatic set up.
