I thought you would chat to him quite a bit...... Well when you next speak to him will you tell him that I'm trying to get in touch with him for 3 three class 37/ 40 roof grills too please (I have sent him an email... and called on numerous occasions). I know he's always busy and he does get back to people but hey if you can speed the process up that would be great. I have two 40's needing grills!!!
With regards building the Shawplan etch, I have soldered the fan, I just coat each part first with solder, chuck it all together (making sure that at least one of the fan blades is twisted into position, then apply soldering iron and wait
As for the grill, I have used solder paste... only a small amount around the retaining hoop underside. A bit of flux on the grill itself and (providing you bend the two items over a Railmatch bottle first) the assembly solders quite nicely.
I can see the benefit of using cyano though.
Cheers
