A thought about the stringing and other issues you’re having with LW-PLA. Particularly if your printer and filament were kept in a cold (damp?) workshop, could your filament be damp? It’s important to keep it dry, as this can affect the quality of prints. I proved this recently when trying to print a fuselage section for a Planeprint Notos F3A. I was getting severe stringing and layer gaps when printing with an old reel of PLA+, I then tried printing the same part with a brand new reel of the same filament (and all the same settings), and the part came out perfectly. After much research, I bought an Eibos Easdry filament drier, and having put the old filament in the drier for a few hours, I tried a test print and it came out perfectly. Another way of identifying damp filament is the fact that it goes brittle. The old PLA+ I mentioned above snapped easily if bent prior to drying, but was much more resilient afterwards.

Millenials. I thought they were supposed to be the 'green' generation 🤔.

Yep, plus another one from me.

I have to say I’ve noticed that Loctite products tend to be way overpriced when aimed at the mass market. For example, I’ve just checked on the B&Q diy.com website, where 7.5g of their ‘Precision’ superglue in a fancy blister pack is £5.36, against Screwfix’s 50g bottle which is £3.59.

I’ve wondered sometimes whether thin cyano should be classed as a chemical weapon. Given its tendency to run around and stick your fingers to the model - or each other (as has happened to me on several occasions!).

Thats why I tend to buy the smaller 20g bottles, rather than the 50g ones which go off before I can get near finishing the contents.

Yes, done all that. Doesn’t work for me as I find it’s not so much the threads that stick, it’s the very end of the tip that gets stuck up inside the end of the cap. I’ve thought about Vaseline (as Robert C says above), but never got around to trying it.

Has anyone ever come up with a way of preventing this?

😱 I think there’s a couple of extra zeros crept in there somewhere!

Never mind that!

He says it’s been well flown and crashed. It’s certainly been well crashed 🤪!

Reminds me of this!

Not this one though. I don’t think a new porcelain tea set or a laptop would survive this kind of Amazon delivery!

BZ4X?

I sold a variety of old engines with some surprises regarding prices obtained on eBay a year or two ago. It's best to use the advanced search facility first to see what similar items have sold for, so you know where to set the prices. I guess the BMFA classifieds are OK too, but I suspect eBay has a larger potential customer base.

No, but I make them as accurately as I can. Why wouldn’t you?

Lucky Boeing and Airbus don’t adopt your philosophy!

Ditto! I’ve recently bought a 2023 RAV4, and although they have improved the previous often criticised infotainment screen with a new bigger clearer one, the temperature and ventilation controls are still physical switches & knobs. Compared with some other manufacturers, Toyota seem still to be somewhat conservative with regard to the use of new fangled technology in their cars.

I wouldn’t be without mine. And as others have said, don’t bother with the Perspex. Although I have used a sheet of thin polythene before, to stop the fuselage under construction from sticking to the jig - especially if using cyano.

There was an interesting article on this very subject by Mike Freeman in the July 2023 issue of RCM&E. I scanned and kept it, attached here... Servo Torque Calculation.pdf
