    Does anyone make there own airgun parts

    Cam trigger was on number 6 a stainless steel G316 semi bullpup 1995 11" long one piece no linkages and proper 2 stage you could blow through 1st and 2nd stage. Took me ages to design and work out all the leverage ratios necessary. Thumb wheels for 1st and 2nd stage adjustment weight. Its the only rifle i disown since it was butchered in 2000 by a supposed top name that couldnt figure the trigger, valve and hammer assembly. So crude it made me cringe no joke left with 1/4" blade creep at 2nd stage, told send it back. Wouldnt be a decent trigger doing that way, 10 mile of creep and exactly like quality shotguns ultra primitive. Number 2 i used to run that at 2.8mm stroke for 5 years then backed it off to 1/8". Only Feinwerkbau have come close to date at 3.5mm using similar hammer spring. Key is i used the valving to stop dumping air back in 92. Titan MS020 i got down to 1.4mm stroke for max power with no side effects, no one else to date has figured. With all the R&D involved even back then at 50p/hr the Titan and first rifle made would owe me £30k labour only. The knowledge i'll take with me when people of today can only copy others work and get great praise.

    See if this works number 2 from August 1993 all done with a toy lathe and no mill. 1st taken apart pre Worlds 2005. 2nd last week same reg used by many many others inc Anchutz, Walther, BSA, Mick Dawes, ISP and may more. Tested still works at 83bar untouched in 13 years. 3rd Trigger a proper 2 stage not a single stage easy to make item.

    Dragged this out last week Number 2 from 1993, shocked still had air in it from 2005 Worlds. Got the better of me partial strip down and front of reg, valve and transfer port o rings rock hard like plastic. That bad had to break them to get them off but still no leak. Have a piccy in 2005, rest are last week not bad considering a hand made one off down to the last screw not a copy of anything all worked out. Wont let me upload more than 512kb

    Anodising

    Theres anodising and theres anodising so far in 24 years i only trust one company having used 12 different companies who will either lose one or more parts or just scrap the part or even lose it time after time guaranteed. Its what drove me to doing my own for a few years I gave up doing it in 2007 still got some hydrochloric and sulphuric in the small tank. The 15 gallon tank broke and seeped out. Digi PSU repaired twice by Mr Dave L on here. Many reasons an anodoser fails, when it comes out bad they strip which renoves metal, have another go, same again and find nothing remotely matches up. Worst still is threaded items, have taken in 1mm pitch threads to find when they come back screw in an extra 290 degrees. What that means is theyve lost or rather eaten away the aluminium threads by 0.76mm = scrap your loss no come backs law to themselves. Likewise can have a good looking part but in the cleaning process its eat away at threads before other areas of the part. Name above dont do it its done by a biker company that will only work with raw or neat aliminium. Take bead or soda blasted in it will be hand rubbed and patchy. FB he will only do mop polished parts which means rounding edges off. A good anodiser will colour match!

    I havent 'made' any for 15 years. Previous to that digi cameras not around. Best lathe ever had on the whole one of them 140's, could put a cut on. I am heavy going on machinery scrapped it 8 years ago with all extras inc full set of change wheels, 11" 4 jaw, coolant etc. Point is you will never know whats best twin transfer port or a single for various reasons over looked. Wondered why you get some good and some bad ones, parts made exactly the same, its down to two things.

    Anschutz quality.

    It runs at 119 bar on my old guage.

    Barrel manufacturing

    Difference is BSA state they never have made that way but have found their way on to finished rifles. Harper used brass liners crimped in an outer tube same with the carbon barrels notably for the Ruger 10/22.

    Might finish number 23 one day, been on hold since end of March 2003. I only do one offs down to the last screw no copies of anything, all has to be worked out. Downturn to that twin transfer port is wasted energy and inefficiency behind the valve. Never heard anyone say polygon barrels any good in sub 12 ft/lb might want to change. For a sec thought Custom of Sheffield made that CS1000. The Titan trigger can work ok but vast improvements can be made by making new sears, still wont turn it in to a two stage trigger.

    Anschutz roll of honour

    First ones i saw were the Welham in 1998 and suffered velocity and zero shift. Had the ugly steel cylinders. 99 there was a team hence 3 guns above mentioned.

    He paid for the 2nd one although a sell off.

    Wooden stocks or metal?

    Theyre all like it bedding my Anchutz in 2005, Fen 2014 plus Walthers since 1998. External stock makers are just copying the disasters for an easy life rather than correcting or making right, none worse than the Ones. Had to put James Woodheads right before he won the Worlds 2009.

    Wooden stocks or metal?

    I would agree with almost every word there Rob. Problem is the designers with lack of knowledge and or unwillingness to design and build what the customer wants just taking the easy route. Big difference to looking nice to feeling right, all judge stock on looks not performance of which there can be monstrous disasters. Biggest is the lack of bedding in by the Germans, only one way to do it, do it right or not at all.

    J Briscoe has hung on to 3 team rifles as they cant be sold, been doing clays for over a decade and good at it. Only Regional wins for me MFTA Masters 2009, numerous W/L and 2008 GP A Series.
