It had been on the "to do" list for some time. The challenge to making a DIY cylindrical is that the alignment of the two lenses is critical. Whilst a DIY prism lens allows for a fair amount of hit and miss, near enough is not good enough when you are using cylindrical lenes, and so I need to be mindful of this when designing the DIY case parts as well or no one will be able to assemble the lens.If Mark is making a kit type lens available for the MK.4, then others may be interested in takiing this up as well..
Not exactly a true DIY job. What I will do this week is draw up all the parts for the laser cutter to run me a prototype. After I have assembled it and worked any bugs out (I have a spare set of optics here for testing purposes), I will be able to start a production run. The end user could assemble this case themselves. The point is that there is a great deal of accuracy required in the design, so why I feel it is best to have all the parts duplicated from a machine rather than having each DIY lens being essentially a one off.I see your point..This is not really a DIY case that just anyone can make up..
Looking forward to hearing further developments..
The joys of machining. For this case, the most economic way to do the case is to laser cut the plastic parts. That way, the case should be less than $100 each.So each case is machined individually!?..That would be expensive..
Obviously, Injection Moulding would be a lot cheaper, but off course that's only practical with a large quantity of units..I see your dilemma..
Given the price of the glass, is the little extra for a tested design really too much?Others here may (like myself) have access to equipment to cut and machine a case as well.. So I am listening for sure.
