Does anyone have a spare swingarm chain guide (i.e. not the guard) for a tornado that they would like to sell? Asking for a friend

Rob,
I'm not sure what NRE tooling is ? Could you explain please ?
This they answered.

Good afternoon Domingo,

This part is a new part. Our supplier states that they can deliver more than one piece!

If you have any questions, please don't hesitate to ask! Thanks and already wish you a great weekend, cheers!!

🤔 I've tried to call them and send them an email, but haven't gotten into contact yet. Perhaps they are more inclined to warm blooded foreigners than ice cold Dutchmen ;)
Anyways, we've got an answer
Rob,

Non Returnable Expense i.e. a machined cavity tool (2-part to facilitate moulded product removal). It would seem the best route forward. I would guess at a few hundred with 100 price 10-15 each. Amortised you’d be looking at less than 20 a pop. A group buy thing I suspect.
I'd be interested in that and would likely buy a few. I'm loving this TNT and will be buying more
100 is a reasonable order quantity i think. How much do they work out at please ?
I didn't ask Alex. It just seemed too many for a "Laurence Bulk Order"
Feck me. The 100off price is 3X what I expected to see. Guess the material build-up time is the same though with little discount for volume price breaks.
I'm a bit surprised by that price as well.
One thing about printing I have been concerned about, is the need for the "nose" to move away during assembly and spring back when in position. I think that CF-PETg is a good candidate for longevity, but I'm not sure if it is flexible enough. Any ideas?
PP is the alternative, but I'm not even sure about that.
Maybe the solution here is to commit to NRE Tooling for a moulded part, and that’ll see the pcs price tumble.
My impression of the cost of an injection mold is that it runs into multiple thousands. So a run of only 100 might not be large enough to satisfy us.

Isn't the slider different on a TNT cf. the Tornado?
It just seemed too many for a "Laurence Bulk Order"
You got that in one :rolleyes:
Errol. Concur your cost for full, hard tooling for K runs however I was thinking ‘softer’ for a hundred or two run so not as dedicated to longevity.
Charles scanned his slider and sent me a copy of the stl file - chain.slider.stl
I've put it in my Google Drive for anyone to copy and print. Charles has cleaned up the file but he reckons it could be improved still.
I've imported it into FreeCAD & I must say, it looks quite good.
Many thanks Charles.

It seems that my guess that Benelli never had any sliders as spares was quite wrong. @CanaryTrek just sent me this https://www.ebay.it/itm/295313270086 They say they are new & there are three left. I'd say that if they are still in their original bags they probably haven't deteriorated. I'll not go there though. I'll stick with fabricating one in two halves from 5 mm PP sheet, and maybe printing one in CF-PETg

Hey Errol I can't seem to open and view that file containing the scan. Can you send it to me in another format.? It seems I have found a mob that will print it out of an oil resistant nylon but the catch is...they need the one I have to scan and create the drawings at a cost of about $1000 AUD. Then $250 AUD to make one. If I had an acceptable drawing for them to be able to forgo the initial 1k,I would be happy to commission 1 or 2 at 250 just to try them. I didn't get a bulk price from them yet...

I do not understand , why look outside the the forum for this part to be printed. I had already decided to buy a new better/ upgraded printer model in the future. If not for the fact I am renovating the house selling and moving, I would seriously consider making these parts for members.
I probably will in the future. But that will be a few months down the track, and a lot cheaper than AUD 250.
Better yet a person learns to manipulate files make cheap copies out of PLA (till they get it right) and then sell nylon copies to members. ( It is not that hard to do )
You never know you might sell enough to pay for the printer, and learn new skills.

That'd be great. I'll look forward to it.
In the meantime I'll try forming a sheet of PP
Good to have an in-house 3D printing solution (y)
There’s also my ‘soft’ tooling injection moulding suggestion and I used these guys a few years back too ..
A mate just dropped in a slab of polypropylene from the side of a tank that partially melted in a bushfire that went through his place a few years ago. UV stabilised too, which is a bonus.

We'll see if I can make something out of it in a few days

I would be interested to know what demand there would be for this part. The reason I bring this up is the need to decide , do I buy the $1000AUD creality printer or the much larger yet to be released over 2000 prusa.
I could also scan and print the chain guard. Any other parts people may want?
Would like to know.

Is shipping cost for a 3D-printed part sent to Europe not prohibitive?

I have made the scan for said part freely available, although needing a bit of development. If a person in Europe put in a little work and sold them , good for them and European buyers. Unknown to me cost of shipping, looking objectively if I bought a $1000AUD printer and sold ten pieces for 150 each that would be a good result. I would have to take into account cost of filament, electricity, failures, Ect. That is already cheaper than having people/ companies outside the Benelli forum making the part ( see earlier posts ). The Prusa printer I am looking at want $400 up front before it has even been released to the general public. With a 300x300 base I was thinking what else could be printed. Judging by the lack of response there seems little interest, and people are ok with buying second hand parts or making their own versions.
I think you will find (as I have), people on the forum only want parts when theirs is buggered. I have a good stock of various parts I have saved over the years , but only rarely do I get a request for them. Laurence has the biggest attic in the world, stuffed full of really valuable parts.

Close, but no cigar. There was a group buy of silicon radiator hoses several years ago. Most, like me, thought that the stock hoses would have disintegrated in 20 years, but wonder of all wonders, they are still going strong - at least mine are.

In the case of the chain slider, as I found out to my annoyance, unless it is pristine, still in the plastic bag it came in and never subjected to UV, it won't be much use by the time the one fitted to the bike needs to be replaced. So, IMHO, the chain slider is the most worthy of a group buy to future-proof the Tornado. In this case, the future is already here - a bit like human induced climate change.
