|Thread: Make your own 'Air Rifle'|
OK, I've had enough. I'm off. Which will please those of you who are uncomfortable with my comments.
I have never come across a bigger bunch of soft jessies and establishment kiss a%$$3$ in my life.
Misinformation my eye. It's people like you that got us the limp wristed 12 ftp in the first place. Happy to see 25ftp used on bunny's and forget the license. HMM. how do you buy a 25ftp rifle without a license. That does not make sense, unless of course you know where you can buy one under the table, so to speak.
I thought this was a 'Model Engineering Forum', not a soap box for commercial and establishment yes men.
Regards all. Don't bother cheering I wont be listening
Bye bye girls.
Vic, presumably you are talking about FX's smooth bore twist barrels, where only the last two inches or so have any rifeling. I think Ben Taylor is the engineer who developed this type of barrel for Swedens FX air guns but way way back men like Fosberry and Metfordwere were adapting and designing this type of barrel with strange twist shapes and rates.
Why hammer forge the whole length of a barrel when you can get excellent accuracy results just by hammer forging the muzzle end. Metford I think it was who designed slugs or bullets with rifeling stamped into them. From the studies I did way back in the day this was not a very successful way to impart spin and thus increase both range and accuracy.
Whoa. This I am remembering from studies I did as a young man, I'm 70 years old now and am having a little difficulty remembering what happened last week!. I look for break barrel rifles that are practically irreparable but the barrels are still serviceable. Quite a few of todays air rifle barrels are only about 16 inches long in any case. So a used break barrel of 17 to 19 inches long can be cut and recrowned or a new lead cut in if the barrel has a decent choke at the muzzle end.

I left the army in the late sixty's, since then I have made many guns and when 'They' took them away from us I started making air guns! The police know and have never bothered me , maybe because they know I will not make them for anybody who is the slightest bit iffy.
It was the air gun manufacturers who are to blame for our wimpy 12ftp for air rifles and 6ftp for air pistols.
At the time the British air gun producers could not make an air gun with more than approx. 11ftp. They just did not have the foresight or for the most part skills to make more powerful air guns. (DUH!). It was the British manufacturers who advised the legislators what power level to set to protect their sales. I'll bet many have kicked themselves in the rear for those pearls of wisdom!
I am 70yrs. young and am still learning about gunsmithing, some people put a few years in and think they know it all. These amazing people do not need to read or do any research because they can do everything without further study.
Let's see how the manufacturers screw up the licensing laws this time.
For those among us who say that licensing is not yet cast in stone I have this to say. 'It may not be cast in stone but it is at the stone masons being chiseled'.

A brilliant book by H M Buckley on how to build your own PCP air rifle.
I am now well into making my own airguns and this book has been of incalculable help.
The title :' The Modern Pneumatic Airgun'
Written by Mr H M Buckley comes with all drawings and photographs. If you want a really fine airgun then this book should help you to produce one.
|Thread: High pressure air pump|
Hiya Geoff, I am about to start making a new PCP hand pump which will be fitted mechanically to pump HPA to fill my airguns instead of all that heaving and sweating. (In this weather).
If you google or use You Tube to ask 'How to build a PCP pump' you will see at least two designs that fill air rifles or scuba tanks.
Not pretty but they will do the job. John is correct HPA is dangerous but so is electricity, so like most things in a workshop, carelessness can get you hurt or worse. Safety is the responsibility of every engineer no matter what level they work at.
I suggest you have a look at the hand pumps available on the market. Hills or FX are reported to be good and expensive too. The tube is fairly easy to find and the seals. You can build one fairly easily and material like 'High pressure hoses' are not expensive unless you buy them from a gun shop. (No offense John but I find the prices in the airgun industry to be a complete rip off).
You only have to look at the HPA gauges the like of AA or FX put in their air rifles, they are basically expensive inaccurate crap. You don't have to believe me, just look on You Tube about how to replace one of their gauges and you will see for yourself the kind of expensive crap they foist on us.
So Geoff you can build a hand pump and with a little thought can turn it into a mechanical compressed air filler, not a huge compressor and it must be watched but it can be done Geoff and with a mini lathe too. In fact Geoff I no longer buy my airguns from the 'Cartel' but make my own. Courtesy of Mr H. M. Buckley and his book 'The Modern Pneumatic Airgun'. The only thing I don't make are the rifled barrels but there are plenty of spare used barrels knocking about.
