People say not to use nails to drive pins out, as the nails are pointed and flare the end of the pin, but they are fine if you grind the point off squarely

But you can buy a set of pin punches from the bay for £7.00 inc postage. I did last week.

Anyway, I stripped my CD trigger unit yesterday and gave the bits a good old polish. I'm a bit of a mechanical noob but I guess I'm not the only one on here. After reassembling I couldn't get the gun to cock. I posted a query about this last night on the main forum and received two helpful replies - I thought I'd pass on my comments.

First of all, is it worth doing?
Definitely!
The trigger is a totally different beast now. Light and precise first stage coming to a clearly defined stop before second stage - it's beautiful!

Two pitfalls I found:
1. Make sure you approximate the same or similar trigger-weight when putting your unit back together. If you follow this guide you will be removing the trigger-weight screw, so make a note of it's position so that you can copy it when reassembling.
2. Make sure the safety button is relocated correctly. Both factors can influence how the gun cocks.

Thanks everyone.

Another rather basic newbie question.
What product would you re-lube this with?
And where would you put it?

I used Bisley gun oil. AA recommend putting a drop or two on the safety button once in a while, so that it tracks into the CD housing once the safety is clicked in I suppose.
Anyway I don't think you need to use anything special.

Will the tuning shown on this thread help remove the "creep/ spongeyness" i have on my tx?

Thanks

If anyone who has done this is reading this, what problems did you encounter when dismantling the trigger unit?

[Ferrets Bueller]

None, its really easy, just take your time, following the guide.

A very worth while mod and just two things to add

While you have your pride and joy apart you could also think about mirror polishing
the mushroom as well, you will notice after you have how much smoother it will cock
and its quieter as well.

Secondly while you are there with your sears and block in pieces give the adjusting
screws a polish as well (the ends that is )it helps your fine adjustments no end.

You never need an excuse to mirror polish your mushroom! Just don't get caught.
