Hw99 stripdown

[TonyL]

Not necessarily snappy, depending which of the Titans he uses and adjusts accordingly.

The standard HW synthetic guide is actually really, really good. A good and strong two-piece design. If it fits the selected spring properly, no need to look any further.

If he finishes the spring off properly, and with the slip washer, all might be very, very good. I'd still always prefer a top hat at the front end of the spring, giving more support and an extra bearing surface with a polished steel or synthetic washer ahead of it. These days a spring just doesn't seem properly dressed without one!

Although a lightweight, the 99 isn't obliged to be snappy. Indeed, in .22 they can shoot very demurely at close to legal limit power. With a correct set-up and running around 11 it should be extremely nice to shoot.

Enjoy once back; I'm sure you will.

It's a no1 spring that he had listed for the 99 if it's no good at least hes tried sorting it but I'm getting a kit off tinbum so will go the maxi kit with oem spring I enjoyed stripping it but know how to do it now so will have it apart again I want to mirror polish everything up and get it as sweet as poss. Even thinking of glided piston etc when the funds allow

Only 'cos you haven't mentioned it. Beware the windows in the tube for trigger block etc. They can wreak havoc on seal lip when refitting.
A good smoothing of edges and consider thin sleeve to get the seal past them. Old film negative etc
Granny, eggs, and all that

This is the most important bit, i had an ongoing battle with my old bsa 635 magnum because i failed to notice a sharp burr on both sides of the cocking slot that was cutting two slits in the o ring everytime i fitted a new one.

Been to pick it up he was inviting deliveries but the spring was on the counter he's fitting it at home and setting it at 10.6/10.7 for me so when it settles down should be 10.8/10.9 hopefully then get out off running and I should be happy ...... Doubt it there's always room for improvement haha

[Kalibrgun]

Called down to get the 99 and he wasn't happy with the cocking effort or the snappyness of firing cycle and asked if I can leave it til Monday and hell get it right if not he will order another mainspring but a genuine hw one (which from what I've read there's not much better) instead of the titan no1. so I'm still gunless at the min and dying to get out shooting

[harvey_s]

Lots on the web about the listed Titan spring being too much (no.1)... IIRC I've seen 5, 13 and 10 all listed as being useable in the 99 albeit with shortening required on the first 2...

[Kalibrgun]

Been back to the shop again still not done it will be weds now he's had to order a hw mainspring. Better be right wen i go down on weds not happy at all lads off school wanting to get out shooting

[mdunn]

I’ll never use him again or recommend the shop, but hope you get sorted. Atb mick

If he has the spring on Wednesday but hasn't fitted it, I'd be tempted to take it home and fit the new spring myself. After all, you now know how to work on it and can take a little extra time finishing / polishing spring ends etc.
