Lovely.

What's the stroke as standard, Mick? And what are you hoping to stretch it out to?

As far as I can make out, Tone, they're the same stroke as the HW50, so about 65mm, which would tie in with John Walther's Airgun book which tells of a HW55 model that used a HW50 cylinder and barrel latch ?

Hopefully I can stretch the stroke to around 72mm but I may be able to go a little more, it's very difficult to give an exact figure until I've measured everything up a few times.
I can't work measurements from the HW50 I have in bits as I have a 99 barrel on that which moves the cocking lever about 3mm forwards of it's normal position.

Ah, great stuff. The HW55 is the best gun Weihrauch made by quite a margin. I have no doubt you could get over 11fpe with an increase in stroke but they shoot magnificently well at 6-7fpe I would be tempted to keep it at that level and give it a good spit and polish tune, sized synthetic piston seal, standard spring etc. They can get very close to the original Walther LGV's in terms of smoothness and I don't think recoilling spring air rifles get any better than that. For a target work in the garden it would be ideal.
Of course, if you can get all that at 11fpe... oof!

Cheers, Mick.. And, no doubt, it'll be lovely by the time you've done with it.

Interested in this thread and see how you get on with it Mick. My old venom 55 t does 10.7 ft lbs. I was planning a .22 version which would bring the power up a little but may go down the route of a barrel chop on my other 55 to around 14inch.. Mach 1.5

I got one of those, it is called a 55M. Unfortunately the stock is cracked at the wrist, another one of those projects that are waiting...

Hw80 I'd say

Hi Paul.

Obviously what I'm doing is not new as Venom did conversions on the HW50 and HW55, I can also recall Bigtoe working on both of these and posting about it in the Collectors Section, I'll do a search later and see if I can post a link.

Hi Evert.

I'm pretty sure that the HW55m action will drop straight into a HW99 stock, as should the HW55 action if the stock was relieved for the barrel lock, if that floats your boat ?
The Old School HW50 action definitely fits into a HW99 stock as I've already done it, but the rear stock bolt hole needs a sleeve in it to take up the slack.
I can recall BBS member, Mattyboy, fitting a HW55 action into a HW50 stock, and from a quick measure up this morning the mounting holes on the HW50 and HW55 action are the same distance apart at 7.25 inches.

I'd love to see a 55 rehomed in a heavier, more substantial FWB300 / Diana 75 etc stylee match stock. When I acquired mine in late 2012 from a very nice BBS member I was really surprised how light it felt and how slim proportioned it is. Thinking logically, bring very similar in action to the 50, I shouldn't have been surprised, but I was. Maybe a possible idea for anyone with a damaged stock?

[TonyL]

The custom match 55 has quite a chunky stock and has the cut out forward of the trigger to add weights, should one wish to do so.

A Hw revamp between a Mk1 50-55 and Mk1 85 combined would be something rather special and that along with a Hw87 would gain Hw a lot of respect if made in the older ways of true craftmanship, with walnut stocks of course

That Custom Match sounds cool.

I think a couple of versions of a revamped, standard stroke 55, one with full match style stock, would be lovely.

Plus a long stroke version in a 85 style stock.

Thanks, that gives me some ideas! The 99/50s I have is waiting on me to fit a ARH/Maccari walnut stock that was generously given last year... I've started working on the final inletting, but its going slow. (better slow than too fast).
That means the stock from the 99/50s would be available for use on other guns.. Interesting options arise, a long stroke old type 50/55 in a modern 99/50 stock could be an good rifle!

Now there are a couple of further lovely projects we'll look forward to seeing.

My mistake, I found a thread where Mattyboy fitted either a 50 or 55 action into a HW95 stock.

At a quick glance a HW95 stock would just need some wood inletting into the cocking lever slot and a new front mounting hole drilling for a 50 of 55 action.
It should be possible to hide the inletted wood by fitting an aluminium accessory rail over it and using a countersunk front stock screw --- just another option to look at.

It always good to catch your own mistakes before other people catch them
