"We are past the period of illegally cutting the forests and now we are working on rebuilding them. There are still areas where people illegally cut the trees, but we work together with the ministry of interior and the ministry of defence to prevent the practice."

In the eastern provinces, local people and armed groups have been involved in illegal logging of trees which are then transported and sold in neighbouring Pakistan. 

It all starts off with a special drill bit which drills two different diameter holes with one drill plunge. This cutaway shows the two holes that have been drilled, and as you can see, the screw can only get so far through the wood.

Also chasing critical dimensions is a very deep rabit hole, one you can go down forever if you want (it all depends on how tight your tollerances are)

In the paper, Moomaw argues that if current management practices continue, the world’s forests will only achieve half of their carbon sequestration potential, and the expected consequences of climate change are so disastrous that this must be taken into account when deciding which trees to cut down.

Timber is one of the country’s precious natural resources. Over the past couple of decades, it has become increasingly scarce. According to anecdotal evidence, during the Soviet-Afghan War, groups of mujahideen fighters found safe havens in the country’s vast woods which prompted the Soviets to bomb them. 

Pope’s brother, also an employee, said there were downed trees everywhere; trees on top of buildings and a mangled mess of campers and trailers.

Purchasing machines that are not yet cost-efficient or enlarging facilities without the staff needed to maintain them can slowdown business growth and actually hinder long-term expansion. In many cases, it may be better to concentrate on making steady gains rather than giant leaps forward, as even a small shop with fewer than a dozen machines or employees can still meet or exceed the national productivity average.

That’s a good Laser 101 page, thanks for the link. Another comment regarding MDF: try to find MDF that is formaldehyde free (cuts cleaner or gives more precise edges) and always check your thickness on each piece. 1/4″ MDF from Home Depot can range from 0.220″ to 0.265″ in my experience.

Definitely this — you can even easily buy cheap FR-1 blanks from the likes of Bantam Tools: https://www.bantamtools.com/collections/materials/products/pcb

I worked on this project over the course of two months, and the one big fear I had was that when it came time to put it all together, it wouldn’t fit. As someone who has always been challenged when it comes to building things that match my measurements, when it all fit together, I was incredibly excited — and very relieved.
