Re: Dreamair cable gun: Carbon Fiber or Alloy Body

Anyone want to guess what a gun would go for?

Volume will bring the price down. Say if a distributor could order and sell a thousand guns then the calculation would be different to the situation if he thought that he may only sell 200, at least initially. That is for a distributor, not the manufacturer. Spearguns are not million gun sellers, but 10 thousand could be a realistic number. You have the whole world to sell to. Some spearguns have long serial numbers, but often hard to tell where the numbers start from as they do not necessarily start at zero. Leading digits can be a series number with the serial number a suffix, hence a 6 digit serial number may mean less than 100,000 guns. Pneumatic guns are often serial numbered, unlike most band guns.

An example is a "Mirage" that I have with serial number 67787, I am pretty sure that before it there were not 67786 made as the gun was an early version, thus some of those numbers are a series number.

Re: Dreamair cable gun: Carbon Fiber or Alloy Body

Back in the old days, when people wrote checks, retailers wouldn't take a check with a number like #103...but you could open an account and start your checks at ANY number, so why not start at #3,400?
Same with serial numbers.

Re: Dreamair cable gun: Carbon Fiber or Alloy Body

Well the carbon fiber "Dreamair Unreal" gun is now available on a batch order basis. I don’t know what a suitable batch size would be, but if say 10 people wanted a gun that would be an order for 800 x 10 euros. That should include the gun and its hand pump which you use to pressurize the gun at the start of the season, or if you want to increase the pressure after letting some air out. Any reel would be extra. These first guns have an aluminium tube inside the gun body that the piston slides back and forth in, similar to the alloy bodied gun tried out some years back, although that gun had an oval bore with an oval piston. That "Dreamair" gun does not look like being produced as all versions will be "Dreamair Unreal" carbon fiber bodies, but with different air chambers as the following diagram shows.

Flanking side tubes in the gun allow a lower compression ratio of 1.5 as gas swept by the piston moving forwards can be squeezed into the side tubes which provide more "head space" if you think of the cylinder head on a combustion engine. With a monotube, as those first guns were, the compression ratio is about 2.0. The advantage of a lower compression ratio is you can use a higher start pressure in the gun and obtain a more powerful shot. A lower compression ratio and you don't exceed the maximum pressure rating for the gun with increments that would otherwise not be possible if the compression ratio was higher.
