Story of Why this story? The channel's weekly summary: what went up this week, what is drawing views now, and where the channel stands among similar channels.
SNNC 663 P1. HW 35 Internal Polish. Trying Cold Bluing.
The workshop had kitchen company. Alongside doubleboost's metalworking projects came "Wholemeal Beer Bread . Wholemeal Buns.", a baking detour that drew almost as many views as the week's most watched upload.
That top spot belongs to "SNNC 663 P1. HW 35 Internal Polish. Trying Cold Bluing.", with roughly 5,900 views. John's air-rifle restoration has given viewers practical things to discuss: previous experiences with bluing paste, questions about where the solution came from, and a query about the condition of the bore. One viewer also recalls tuning spring air rifles with Gerald Cardew's writing close at hand.
The second SNNC installment, "SNNC 663 P2. Brake Calliper "Helicoil" 10/1mm.", keeps the repair theme going. Then comes a rather different engineering proposition: "Catch Up 120 DIY Gas Turbine (jet pipe & test stand)". It is the newest upload and currently the channel's busiest video for daily views, with the bread and HW 35 videos next. For a channel whose introduction includes a jet-powered go-kart, a homemade turbine is very much at home.
Subscribers stayed unchanged, while daily viewing is running about half above its usual level. Among nearby DIY channels, Workshop_Shorts had a much larger viewing week, while SuperHouseTV was quieter. Doubleboost's own week brought about 36,000 views, with room for both a brake repair and a batch of buns.

Hi John , nice job with the blue . In the past i have used the paste to blue gun parts up and it never looked right .
@raymondsteele4142See it on YouTubeI've seen bearing spring guides before so the spring can spin freely.

You restoring this old Weihrauch HW 35 reminds me of the days when we were heavily into tuning spring air rifles.....Gerald Cardew's book titled 'From Trigger To Target' was an essential read for those into tuning air rifles for consistent accuracy and performance.
Seventy five years on and they still make limited editions of the HW35 ......a truly classic high quality air rifle.@howardosborne8647See it on YouTube
