In praise of Webley air pistols

[ggggr]

Weirdly, the Tempest locked up again yesterday after my first shot with it in a couple of weeks. Just the same as before. I'd shot a couple of dozen pellets the week before that and no problem, but yesterday the problem recurred. I gave the sear a poke from below, just pressing with a pick and wiggling it around a bit, and it popped back into place and worked fine again to cock the pistol. I didn't shoot more as I had somewhere to go and haven't fired it since, but I'll give it a try soon and see if this keeps happening. This instance helps actually, as it makes clear that it's a problem with the sear's travel. Like it's over-travelling somehow, just a little, after firing. I might have to buy or make a new sear, once I figure out which part of it isn't quite right.

Hi Gerard---IF you are going to but spares then order a sear spring and sear. That way you could try the sear spring first to see if it cures the problem before changing the sear. I know suggested a lot already, but this does seem a sear related problem. I', assuming your trigger spring is ok?
Try swopping the sear pin for the sear stop pin, just in case it is a little bent or tight.
WITHOUT buying spares, this is what try if you feel up to it. (1) take out the trigger and lightly take a little off that bump between the trigger pin hole and the square bit that holds the sear. Also take a little off the top of the square bit as well and then lube the trigger up and retry it. http://www.airgunspares.com/store/pr...-Trigger-Wide/
(2) if that does not cure it then remove trigger and sear and then lightly take a bit off the front,bottom and angled bit at the back on the long leg of the sear http://www.airgunspares.com/store/pr...t-Pistol-Sear/
(3) if that does not work then strip again and remove the safety catch.


The reason for the first two is that maybe the bottom or back of the sear is just slightly dragging on the trigger. I cannot see (3) really affecting things if the pistol does fire, but there is always a chance the safety slot is not cut or aligned and the trigger sometimes does not fully return.

I bought a new sear for my Webley Senior from Knibbs and after fitting it the pistol refused to cock.

I refitted the old one and it cocks every time.

Any ideas why the new sear from Knibbs does not work?

It is the same "later" type of sear and I have tried re-fitting them both several times - with exactly the same result every time!

Probably because a lot of the spares are badly made. I had a sear for a Premier (thread on here) that needed an ANGLE GRINDER to take enough off the bottom to enable it to cock.
You should notify Nibbs and send it back an hopefully the replacement should fit. If people don't notify them of problems, they will carry on getting and selling the same poorly made parts. It does not say that it requires some fitting so it should be fit for purpose http://www.airgunspares.com/store/pr...y-Senior-Sear/.
If you want to have a go at it, then remove the mainspring and push the piston back to see if it engages. (It probably wont, but if it does, the chances are the holding face of the sear needs a little taking off it as it may be too thick to enable the piston to engage OR the edges of the sear are too wide---does it slide in the trigger housing ok?).
If it does not cock, then take out the trigger and try it again. If it does not cock then, then it is probably the sear face.
If it does now cock, you have to look at whether the sear will jam on the trigger or the trigger is jamming on the trigger spring or the housing.
All this is easier to do with the mainspring removed.

How you getting on with that new trigger spring Guy?

[eyebull]

It is an improvement but I will try for something even lighter at some point. O could do with getting a spring and bending it or maybe some sort of adjuster for length of pull/take up.

Just brainstorming here, but could you tap the hole in the top of the trigger blade that the old spring went into, and use a grub screw to increase tension on the spring..?

The new sear slides in and out of the pistol nice and freely so maybe they made it too tall ( or short) ?
