72-74 indicator parts

@Nils - don't suppose you do any parts for the 74-79 indicator/turn signal switch? I'm looking for a couple of replacement white plastic cancelling tabs.

@Nils Me too^.

 

Hi guys

Sorry about the late reply, I once again I didn't get a notification? This tapa talk does quite function as well as the ole' email.

Anyway, in regards to the later model parts. I will start looking into it. Doesn't look too hard, just need to get hold of an assembly to measure and test on.

Hi, I have been reading this with interest. Did anyone find where this can new 3D printed in the UK? Anyone get one done and a what cost?

 

@Nils Did you make any progress with this?

 

Kind of,

You can get the file to print these on thingiverse,

Thanks @Nils, I printed a couple and so far, so good but they’re a fiddle to fit and it’s a poor design. The ‘M’ shaped spring puts a surprisingly high force onto the small and flimsy tabs and when they break the spring moves around and sounds the horn.

 

Nice work Nils, what software do you use to create the file?

 

Can't take credit for the late model part on thingiverse. It was just pointed out to me while trying to chase down a used part.

All my drawing is done on solid works, I originally bought it to work with sheet metal.

Thanks anyway. I wouldn’t have found it, or even known where to start looking. They need a bit of fettling to get a decent fit but that might be the quality of the printing.

@Steve Speirs have you fixed yours?

 

I think it could be worth getting nylon sheet material and a Dremel and making them by milling them from solid plastic.

It could also be worth considering the 'horizontal' that you use to 3D print from. The stresses may be better managed if you print it so the whole thing is printed at maybe 45 degrees so the strands of filament are laid down in a direction that stops the spring pulling the hook off. It also looks like there is actually room to beef up the hook part, or drill and glue a metal pin so it intersects the spring in the crevice of the notch on top..

 

Fixed mine in January (found someone in the US selling a used indicator stalk). Sold my late bay a month later.

 

G'day Mike, Thanks for your input.

The orientation of the print and how the finished grain structure would effect it's functionality, as well as materials were taken into account very early on in the project.
The use of selective laser sintering (SLS) and multi jet fusion (MJF) technology for the prints negates a great deal of the directional "grain" you would get with with fused deposition modeling (FDM) which you would generally have on your desktop. Using this process the versatile plastic (nylon 12) used in these prints has an XY to Z strength variation of only around 5% for the SLS and less again for the MJF. Even in it's weakest plane we are well above the requirements required for these parts.

Though the material in both is technically the same I find the SLS (white parts) a little more slippery and the MJF (black parts) just generally a nicer finish (technically a little stronger too).

Rest assured these are well tested and there are 100's of buses running around with rebuilt indicators and wipers using these parts

An alternative way of fixing; Seems to work ok.... so far... which isn’t very far to be honest.

 

That looks better than the original. I could have done the same but it would only cancel on one side, the other one had disappeared. So far the black 3D printed ones are holding up but the design really is a bit flimsy.
