So... I made a very small Vulcan B1 Flying away in its natural habitat, the skies of my modelling desk It's a cast of a small vulcan pin badge made with some reusable moulding stuff I have. I was just playing around with it trying to figure out how best to use it and this is my test subject, I'm going to mould another tonight hopefully I'll get a better cast. I used too much material on this one and well, it ended up a little chunky. The wingspan is about 2.6 cm so I think that's about 1/1100 scale. Crazy small. ^^ and that's after cleaning up most of the excess material Here's the remains of my previous attempts at this, different moulds (the one I painted up came out of my third mould).
Notice: Go here to see a later post in this thread to see the final result: http://www.britmodeller.com/forums/index.php?/topic/234991809-finished-homemade-spray-booth-project-an-attempt/?p=2186396 I will have to do some detective work, but I thought I'd start by making this thread. I acquired this nice transparent storage case shown in the image below, and I have 6x used Noctua NF-P12 fans that fit nicely at the bottom of the case. I think I can make this work, but there is one problem that I am not sure how to deal with: Q: How do I power the six 12V (1watt) fans from the 230V power outlet? Presumably this is easy, but I have really no idea. Hopefully someone knowledgeable can chime in and state the obvious solution. That would be much appreciated. Putting on a hose and finishing the rear part behind the fans seems easy, so the power conversion problem is what seem difficult for me at this point. Ah, I forgot to point out the specifications for the NF-P12 fans: DC 12V (unsure if the 'direct current' part is important) Size: 120 x 120 x 25mm Rotational speed = approx 1300 rpm Airflow = 92,3 m3/h = 1,54m3/min = 54 cfm Static pressure = 1,68mm H2O Acoustic noise = ca 20 dB Input power = 1,08 W Input current = 0,09 A 1,54 x 6 = 9,24 m3/min = 324 cfm (unsure if it makes good sense multiplying these numbers by six) 9,24 seem to be double of what a popular spray booth seem to push out, though I am not certain the numbers for these two solutions are directly comparable. *unsure* Edit: Hm, I wonder if the six fans would be powerful enough. The popular spray booth on Amazon uses supposedly a 25W fan, which seem more powerful than my 6,5W setup. Not sure what to think about this. I have a 15cm wide table fan that uses 20W, that one doesn't really feel that powerful to me. Hm, I vaguely recall my compressor having 17L/min airflow, roughly 40-50psi constant pressure, unless I am totally mistaken. Maybe around 9L/min with 25 psi? Just guessing though.
