Mosfet fitted and tested. It worked! - HURRAY!! I had trouble with the extra wire. It wouldn't fit in the gearbox so I've had to cut 2 locating pins off.
Waiting for parts sucks!

Reshimmed with new gear. I took the mosfet off, weren't happy with my soldering job. I'll get someone at work tonight to redo it tonight.
I put it all back together, it was so easy with the use of grease

Yea I might change them for 1.5mm cable. I'll sort it tonight and then test it. Hopefully I've shimmed it right, fingers crossed!

Rewired the mosfet in and put it all back together. IT'S ALIVE!
Tooks me a few hours this evening. As someone previsouly said, the wires that came with the mosfet are huge. So big that the first time wiring it up and trying it the motor cut through the wire. I had to strip it all down again and got some 0.75mm red and black wire from work. The wiring job is appauling to be honest, not my proudest work i've done. I found it really fiddly and had to reuse the original motor clips as the ones with the mosfet broke (probably my fault).
Anyway, I'll have to try some round through it tomorrow when I'm home. Not too sure if I've gained any ROF yet (Changed the gears, bushes for bearings and shimmed it while it was open) but atleast it's ready for 11.1V lipo and a lonex A1 motor.

I've just watched loads of youtube videos. It's pretty easy really; a few gears, a piston and a couple of springs. Once you grease it up in there it holds most of it in place.
Rewiring took the longest time. Reshimming only took about an hour - no grinding or crunching sounds so far.
Just ordered the last of the internals to finish the job off;
70D Sorbo pad
Ported cylinder
bearing spring guide
Hopefully I won't have to open this sucker up for awhile after this. All that's left is a Lipo & motor which I'll look into after payday

Ahhhhh but I am guessing coz only done 2 rebuilds so far - and not happy with first one
so may redo it soon....
but like I said I imagine as with many many things only after about 6 or 10 times do you
really start to fully understand and become at ease with stuff like diagnose & rectifying
any problems etc....... = experience
Many things now I got a better understanding of and after gaining more experience and
the odd screw up too (learning from mistakes = wisdom)
Gearbox's - hmm think I got quite a way to go just yet before I can say I have started to
fully suss out n all that, probably never ever master them like some on here - samurai etc....
but hope to one day rebuild a gearbox with some custom parts to a level that I feel happy
with - and I am a really fussy bastid to say the least...
best wishes with ya own build I'm sure it will be fine

Thanks, I'm hoping this gun will last a few years. I realise that modding the ROF will put more stress on the parts but I'm hoping it isn't too drastic. The big difference will be the motor and battery, may need to get a new spring to speed up the piston.

Tried a few BBs through it this evening. I wish I had a chrono to confirm but it sure looked like the rof has improved. The trigger response it really noticeable. I have a stock TM mp5 and the trigger response compared to that is like night and day.
I'm very happy I've done this, it makes me feel like a competent airsofter. It's daunting at first, especially when you haven't got anyone around to tell you where you might of gone wrong. If you take your time and inspect how each part meshes with another one it shouldn't be too difficult. I think everyone should go through this procedure before can call yourself a serious airsofter.
One thing I would suggest which I wish I had done is take pictures as you go along. It might just save you an hour of trauling the internet to find out which way a part goes or where that "extra" spring might go
