Ah I see
Was wondering about DLC coating an action and bolt but I guess the coating place do not have certification to do such work
Coating an action is easy, and if you strip it down enough, then they should be able to do it.
Have a word with your FEO, just to make sure. I attach a pic of action I am about to get DLC'd, while we Cerakote the barrel and bolt lugs here. The bolt is something I will simply jewel and leave shiny. You don't need to recertify anything or reproof it as DLC is so thin it does not cover up the marks. Problem you hint of is a full barrel needs the coater to have an RFD or a FAC with that firearm on it, but part of an action should be OK: again speak with your FEO.
On the suggestions to build up industry:
On another account most raw steels today are lower quality than those made in the past in many areas as we use a higher amount of unknown multiple times re-cycled unknown in the mix . Of course then we have China now and its endemic low integrity in trade. We have to build some more smelting / rolling plants and Global warming is as it says Global so we aint being more environmentally shipping it in from the other side of the world !
Rather off topic, but you echo a common viewpoint, that is detached from reality, so if you pardon the rant:
The reality is the British govt is dead opposed to industry, and has been for decades. Most people see the facts but do not do the sums of 2+2 and recognise the consequences. Look at the facts:
1. Electricity is £0.46 a kw/hr (yes, companies pay more than residentials), due to net zero and the crazy marginal pricing policy we have, compared to less than £0.02 in China, £0.01 in Nigeria or Argentina. Mexico is £0.07 kw/hr compared to £0.13 in the USA. Do you know how much power smelting takes, or simply heating an industrial building?
2. On top of that we are charged for the rain, yes, rain on grass, is charged at around £10k a year by the mafia like enterprises that Scottish Water subcontract consumer supply to. This is on top of sky high business rates.
3. Then UK min wages have doubled as increasing them raises tax, so now unskilled labourers are getting almost as much as skilled toolmakers, which is double the wages elsewhere. The recent Employers NI rise of 50% is just the straw that breaks the camel's back. Universal credit means people get paid more than that to stay at home, which as a result of the Universal Credit explosion, means taxes are so high, that take home pay is an insult to the years of dedication it takes a technician to learn his trade.
4. Mega immigration is destroying the prospect for pay rises, as taxes have to stay high to support them, for decades. You cannot increase the price of your goods to cover these rises, as competitors overseas will take your market if you try it.
5. On top of that is HSE and others who do random inspections, as their specialist used to work for a direct competitor and from their action still does. HSE can write you as many letters as they like, even if you do nothing wrong, and you have to pay them £460 per letter, no appeal process whatsoever, if their man works for a competitor, he can flood you with letters reminding you of the things you already know and told them when they came. They can visit as often as they like, which shuts down production for the day as the managers have to go around with them, explaining that garnet or aluminium oxide is not a toxic chemical, or why there should not be a fume extractor where there is TIG welding of stainless underway - you could not make it up.
6. Making things involves a pile of paperwork: US is even worse than the UK for this, so John Deere emigrating their business is no surprise.
7. Cost of refuse is sky high, even for things that are easily recycled.
8. Rip off Britain: Send in a VAT form a day late, or a Corporation tax form an hour late, the fine is thousands of pounds, so your accountant being sick for a day can really add up. Edinburgh council charge £60 for infringing the LEZ, rising to almost £500 if you do it a few days in a row before the fine letters arrive and you realise where the zone is - so just don't buy anything from any company in an LEZ, while skirting around it takes double the journey time. However, shoplift £10,000 of goods and the fine is just £100, or plough up crops with an electric motorbike and get only a telling off.
9. Despite the words, UK govt procurement despise medium sized companies. We have not sold anything in the UK, other than some trials which went perfectly but no procurement. Procurement is stuffed with inefficiency here. We export all over the world, everywhere except sanctioned countries, but have not sold a bean to the USA or UK. We have never had a grant, we have done a lot of genuine R&D, even our R&D corporation tax reduction claims are kicked about. This is unthinkable in Japan for example, where the govt does buy local where it can.
Forget the ideas about sorting out the UK, it is all too far gone. Just do what one does, then sell up one's house to emigrate somewhere peaceful to retire. House prices are absurd due to interest rates being too low, and the huge immigrant influx where many often share a house, but it does have the advantage of funding you when you retire.
On the matter of steel, Chinese companies can and do produce some excellent steels. India also. I have not witnessed the "low integrity in trade you mention", unless the supplier has been from the UK. You get a full analysis of the steel when you buy it anyway. The problem is Britain does not make steel, and requires now, that you have traceability back to the rock to prove the rock does not come from Russia - this costs a week of work per import, which can end up in demurrage charges that could fund putting man on the moon.
When you add it all up it is far easier to move manufacturing overseas, then come back to Scotland and go deer stalking, ignore all the idiots running the country and just appreciate a beautiful day on the hills.
