Aprilia inside door handles

[ben]

Have just given a broken one a good thumping and revealed the following:

That's interesting.  It makes sense to have a screwdriver-like flange - it might offer more grip against the casting of the handle than another splined end (an engineer can probably tell us).  That handle looks more like pot-metal than brass; were they made in more than one type of material?

If the handle I photographed is wanted as a pattern, let me know.

Ben, thank you for clearing that up.  I always imagined (I don't know why) that the end inside the handle was also a spline  I think it was probably made that way to save costs.

William C, I will let you know, as in the meantime since my appeal, some more offers of sample handles have been made.

Regards,

William C, you are right too that the screwdriver-type end of the spined shaft would make it strong to withstand the torque applied to the handle.

Now I also have a better understanding of how the splined shaft needs to be fitted to the handle.

Is the orientation of the shaft in the handle very critical, or do the splines allow enough minor adjustment so the handle faces (more or less) the right way?

Now I'd love to have a sample of the spined shaft too please! 

(All these thoughts whirled around in my head at 03h45 this morning when I was woken by a thunderstorm!)

I don't think so, there is fine enough adjustment available to position the handles where you will.   I was assuming, if we are using stainless steel or brass, that the splines would have been cast as a piece with the handle?  But I suppose this may not be possible mechanically as the splines may need to be machined?  My original doorhandles seem to be cast in rubbishmetal (some sort of zinc alloy I think that decays after 20 years).

Incidentally, apologies for my confusion earlier  re door handle splines.  Splines tubes??  Don't know what I was thinking of!  The hollow splines in the window winders are cast in situ of course, less stress on them.

[St Volumex]

David W, that's good news and will make them easier to make.

I have all but decided to make the inside door handles WITHOUT the splines cast inside them, as that creates too many manufacturing headaches, and limits the number of handles we can make at one time.

See http://en.wikipedia.org/wiki/Mazak_(alloy) for more on that rubbishmetal!

Guyz i just bought handles today from cavallito in turin someone already making them in italy.

[St Volumex]

I heard the ones from Cavalitto are Euro 100.00 each?

[Parisien]

As theres quite a bit of interest would you ask Cavalittos for a group discount?

I will ask this morning. I had a quite from a guy local to me to make a small batch but the cost was about the same. You have to make more than 100 sets to pay for the tooling to make it wort while and even then he said it would be about £20 handle before chroming. Chroming is expensive too so I think the 100 euro  handle not to bad if you want the real thing. Unless someone wants to spend £5000 on making a load of handles and keep in there shed for the next ten years

[St Volumex]

I am still prepared to make batches as small as 24 stainless steel handles at under £70 each. 

[davidwheeler]

That's about 100 Euro...

[davidwheeler]

That's door handles which can be substituted.  What I really need is window winder handles.

[St Volumex]

£70 is only an estimate based on a very small production run, and at this stage on the LMC forum it seems we only have enough people interested in half of those. 

I'm prepared to make anything as long as it makes economic sense, and provided I can get a decent sample.

Hi guys did ask Cavallito is not willing to reduce price for handles.
I only need the door opening one's
