Bengalensis Posted January 7, 2023 Author Share Posted January 7, 2023 As I suspected the aluminium is far too hard for any manual work with a drill or a knife. Putting them in the lathe will just add marks and they will probably be too thin anyway. So it's hand held work with the Dremel and a thin fine diamond cutter. This one is a +40 year old industrial quality piece. Slow going work to keep control and avoid too much heat build up. Risk of damage? Probably substantial. One done, fifteen to go. 25% done. 11 Link to comment Share on other sites More sharing options...

But I have three left hand fingers that aren't too happy after the strain, they tell me some rest is needed... With a lesser/cheaper tool piece I suspect this would have been a more problematic work than it actually was. 1 Link to comment Share on other sites More sharing options...

Bengalensis Posted January 7, 2023 Author Share Posted January 7, 2023 I made blue tac blobs on both sides like this to try to keep the stacks lined up when the whole thing was turned around. It all seemed to hold up, so I started gluing the end pieces one by one with a tiny amount of CA at the bottom of the little peg, constantly checking all alignments and lining up, and making adjustments as necessary. I wanted very good rows and line ups, but not necessarily 100% perfect, just aiming for that. Going forward one after the other, and sometimes going backwards, I reached something I thought looked promising. I played a little with the engine cover and felt that there was hope for a life after this critical step of the build. So all the joints were filled with CA, little by little one by one, using my trusted #11 knife blade applicator. That will now cure over night before starting to sand sixteen unbroken pipes from this. I'm quite happy with this being done, and feel there is good reason to celebrate with a lovely warm up video - on high volume: 12 Link to comment Share on other sites More sharing options...
Neddy Posted January 7, 2023 Share Posted January 7, 2023 At the risk of repeating myself, that's a lovely piece of work. The alignment is spot-on, I can see how much work it took to get there. 1 Link to comment Share on other sites More sharing options...

Sometimes I tend to make my building somewhat complicated, but this is another of those cases where it's easy to write instructions just saying glue A to B, but the parts wiggle around and can point almost anywhere, catching you out later on in the build. 16 hours ago, klubman01 said: Wow!

Trevor Many thanks Trevor! The sound of these things is just mind blowing, I can watch warm up videos for half a day if I'm loosing control... 16 hours ago, Sabrejet said: I think my legs are in that video somewhere!

Bengalensis Posted January 8, 2023 Author Share Posted January 8, 2023 This morning all the joints were sanded and in a few spots some more CA added as filler and sanded. A first round of primer revealed a few more spots that got some extra primer added with a fine brush, then some more sanding. After a second round of primer I felt the pipes were good enough. Time to glue the photo etched clamps which again require some careful lining up of the parts. With all clamps done and CA cured another thin coat of primer was sprayed. And we have some finished exhaust sections, ready for paint. Actually all the engine and gearbox parts are now ready for a primer coat, then painting. But first I must regain control over my work space; it is again a cluttered mess. 9 Link to comment Share on other sites More sharing options...
Brandy Posted January 8, 2023 Share Posted January 8, 2023 Those exhausts look almost as good as the engine sounds! Very precise, and the extra effort will most definitely be evident on the finished model. Ian 1 Link to comment Share on other sites More sharing options...

It took a bit of work but it should be worth in the end. 43 minutes ago, bosscat said: what primer do you use on white metal or aluminium parts? I mostly use 2K automotive products, usually PPG. If I expect more of sanding and surface preparation it's a primer-surfacer that builds a little more and is very nice to sand, if it's metal and I don't expect much preparation work before final paint it's an etching primer. It's my choice since many years and the reason is I also mess around with 1/1 scale cars where I use these products and find them reliable to work with. They're not cheap though and you need to know what precautions to take, even if we are talking very small exponation in modelling use. Link to comment Share on other sites More sharing options...
Bengalensis Posted January 8, 2023 Author Share Posted January 8, 2023 It's ridiculous; I shouldn't be surprised by the number of parts to prime and paint as I have prepared them all, but I'm still surprised by the number of parts to prime and paint... As soon as the white resin disappeared the gearbox looks much more up to the work. 12 Link to comment Share on other sites More sharing options...
