Ampt Engineering - Ti pedals

[dazz]

New boutique pedal in the works.

Worked with Pat a while back. Great enginere, engeneer, engeneer, he's good with math, so I reckon these will be the business.

Ti spindles and 3D printed bodies?

Yes.

3d printed titanium in a highly stressed component that connects you to the bike... What could possibly go wrong....

Wasn't there some issue with that where the max force data they were given and designed around was actually quite a way below the actual force generated by the cyclist(s) when taking off.

Yes. AusCycling cocking up as usual.

I'm sure the pedals will get some stress and fatigue testing, I just wouldn't want to be the one going full "Courage Adams" off a stairset to flat to see if they hold up though.

That's like saying all carbon composites are brittle and all aluminium is soft. All 3d Ti is not equal, and I'm sure Pat will have gone through countless design iterations and FEA studies based on the strength and fatigue properties of this particular material specification. He's not some random unqualified hack, I thought I made that apparent in the first post. Ultimately the proof will be in the real world testing.

Bastion aren't random unqualified hacks either

Yeah, 'cos a set of ultra light mtb pedals is the right parts selection for doing that..

I never said they were. Can only design to the parameters and information that's available.
Pat will have arrived at his strength, fatigue, stiffness and weight targets with a very different set of parameters and assumptions compared to your Bastion example.

Auscycling on the other hand...

 

[wkkie]

Australian company?

 

[dazz]

Yeah, he's a MTBer and an enguneer. Aussie start up near Ballarat. That's his first prototype for testing. Pretty cool I reckon.

 

[dazz]

Shoot him some questions on his Insta if you have any.

You know there is some dodgy people up there yes?

 

[oldcorollas]

At least he's using Verniers (jokes..)

Nice FEA (full size image here https://static.wixstatic.com/media/746860_3590fe5f66c7411a9f7a553f9a48bced~mv2.jpg )

Did he use one whole fat bastard for loading forces?

That's my attitude to nylon pedals. I know they should be fine, but they just give me the heebies.

Pat's just set me straight, this one's just a printed plastic platform for pics and visual. Investment cast Ti pre-production samples are due in March.
I'm gonna have a spindle and bushing set in my hot little hands tomorrow to have a closer look at.
