Au contraire, selling bits of plastic to the disabled is where it’s at…

I’m trying not to even think about how much I could sell my design for, because I don’t want to…

I think we’ve had almost all of those dude 😉

catch the light on the disc. If you can cause a smear on the braking surface with a clean bit of tissue, then it’s contaminated.

This place is full of most excellent people…

Thanks Andy – I’ll bung you the files. Cheers for the offer.

Gosh that’s weird. I don’t understand how these things can happen, you can add features but you can’t delete them properly afterwards? I guess there is a reason to do with the intersecting rounds, I’ll take richmars’ advice and not use rounding ’till the last steps. Another friend of mine was grumbling about using SE as a preprocessor, maybe it’s just not good for this?

Any tips about where I can learn more about how to do it better in the future?

For the other Rich:

He’s saying the model is full of faults or discontinuities.

FEA is simplification of a solid object model [which contains effectively an infinite number of bonds and connections between molecules] to a finite number of connections with known behaviour [f=kx etc]. This allows Finite number of elements to be analysed, a simulation run to determine the behaviour the connections between them, and thus derive a useful model of the behaviour of the object subjected to loads.

Basically, computer structural analysis of a solid model.

Breaks/gaps, or self-intersecting surfaces will cause problems with the analysis, and because I’ve added blended rounds to the right-angle edges, and then deleted them, it’s buggered up.

…why?

?some sort of repetitive gripping and squeezing exercise, perhaps?

Thanks Rich, I’ll remember that.

Hmm, yes. We were taught Ordered, but on placement I started using Synchronous. I thought the one was a replacement for the other, certainly being able to modify things on the fly is great, but it does tie itself in knots.

Is there a good online course for SE ST6? Beyond the tutorials I mean. I need to be shit-hot at it next year for my Masters!

I think it’s just a case of knowing what you’re doing, and I’m the only guy using SE, or doing sims, so I am kinda out of options for help around here 🙂

Maybe someone more 1337 can fix it easily?

Toys – Just sending an email.

Rich, I think you’re about right, but it’s not the rounds that make it strong enough, I just foolishly wanted to include them for completeness, but now they’ve buggered the modelling. 🙁

Cheers guys – I’ll send the .par and .stp to toys19 as soon as I’ve finished the part I’m working on. If he’s not able to fix it I’ll send it to takisawa2.

In SE there’s “Chamfers” and “Rounds”, I’m sure they’re all the same thing.

Thanks!

Evening bump

Bump for justice…

Well, if the aim was saving money, then yes.

Just developed some photos.

Shitting myself.

OK, When do you need to have this done? You might be best doing it at the Uni…

We’re printing with TPE on a Makerbot [2?], I’m not sure if it’s Ninjaflex, but it’s pretty similar. The surface is pretty slick. I was looking at a nut and bolt made of TPE we’d printed yesterday at the University of Bradford. It’s squidgy, but also functional with a 5-8mm bolt dia.

Makerbot[/url] 2’s can print 284 x 155 x 152 mm

The print above was done on a Mojo 3D using ABS with PLA dissolvable scaffolding. I’ve not tried to trim it yet, a bit scared of breaking it, but it’s fully hollow including the tubes/handles. It’s 70mm tall.

So – can you do it at the Uni?

If there’s no 3D prints available of good enough quality – try Protomold[/url]

What size do they need to be?

I’m working on answering your other questions…..

Greasing some gussets, and not checking all the bolts everyday, or you’ll bugger ’em up.

Carbon road bike with plastic pedals. You’re a perverted guy, is all I can say, Derek.

Two things:
Hell yeah, maybe lightweight ones, but yeah.
And
Try to work more on the ‘over the top’ and ’round the back’ part of the stroke with spuds too…

I’ve just heard back – my Alfine is trashed.

The alfine 8 is a far superior ride use mine almost daily.

Conversely my Rohloff has around 10,000km on it and has never missed a beat*, whereas my Alfine 8 might have done 200k and it’s full of rusty water in a Madison service center somewhere right now.

I suspect it is more suited to touring though, it is possible to “jam the synchromesh” and get stuck between gears, as well as forcing you through gear 14 for every shift. Both of these are only problems if you’re desperately mashing the pedals at the same time as cranking the shifter all the way around. It is also pretty weighty. TBH though, if you’re dropping £1k on a hub, buy a top end crank set and wheel components and you’ll likely come out pretty good for weight.

I will never tour on anything else again.

*Except when I bust it’s oil seal wrapping a bungee cord around it at 30km/h – but:

They fixed it for free. In Australia. In 3 days.

Problem shows-up on ARM Chromebook and also Win7/Chrome

…didn’t help. Interestingly after waiting a minute for Chrome to stop the dodgy Flash process I often get this page appearing as-if I had clicked on it:

http://www.chainreactioncycles.com/customer-service/easter-brand-bonanza?utm_source=singletrack650x80&utm_medium=banner&utm_campaign=easterbonanza

Maybe it’s Chain Reaction’s wonderful website?

The best workaround seems to be hit the link you want on the forum and then get your mouse over to the stop button. Hit stop as soon as the content has loaded but before the dodgy ad or whatever does. Turning off flash in Chrome Plugins doesn’t seem to fix it for me.

Anyone else getting this.

Yes

I’ll try clearing my cache….

This is interesting. What about other substances, prescriptions, or otherwise? And, dare I ask, if you’re riding, do the same rules apply?

I have nasty scar from catching my arm on a slate hedge* while pissed.

* What sort of unt makes a horizont=l slate Cornish hedge?!

Don’t spray solvent/oil on polymers, it might change the colour, cause weakening or increase friction if it’s too light an oil.

Not out much right now but will watch what I can in Bradford.

Try the search function….snigger

Try this….

The last new pressing I bought was shit – full of crackles and surface noise. Warped too! I was about to return it but I dropped the sleeve and damaged it.

Shame, some good tracks….

Not everything is available digitally, nor is it the same experience. It is also unlikely to be as cheap, or as fun as a car boot find.

I use a Rega Planar 3 🙂

Chrome+Flash are having/causing trouble with some ads on STW at the moment.

Halfords used to do a set or two. Quite small. If falling off is likely maybe look for gloves with wrist guards?
