It's a long shot but has anyone succeeded in replacing Skyway hubs using original rivets rather than using those ugly bolts . . . what tools did you use to set them
Any help will be much appreciated :daumenhoch:
Steve
-
Steve, do you have the original rivets,any chance of a pic :daumenhoch:
-
didnt jay do his own
or try ya local skool and ask the metal work teacher
prob called somit else nowadays tho lol
-
Im sure a machine shop would have the right press and rivets long enough to do the job mate - reckon it would just be a question of shopping around.
-
I have one original rivet here which has been lent to me to take measurements. I also have a contact to get some made in either stainless steel or alloy. The tool I need to set them properly is the problem as I'd like them to look original without damaging the wheel

there is few posts on vintage about them,showing a small machine,press etc ;)
-
Is there . . . I'll have a look and see what I can find. Thanks for that :daumenhoch:
Steve
-
if you can get all measurements so i can explain to me mate he might be worth an ask
-
Cheers Dan . . . I'll take some measurements later and post them up :daumenhoch:
I think the easiest way would be to have a rivet in hand to show the engineer
I reckon large amounts of pressure are required to set these rivets properly so the tool will have to be strong enough to cope with that. It will also need the correct cup to leave a nice button shape once the rivet is set

Steve I already have an engineer friend trying to get hold of some for me, or if he can not find them, he said he could turn some. He also has all the tools to rivit them.
When he sorts them out I will let you & anyone else who needs some know :daumenhoch:

Cheers Chris . . . that'll be spot on mate :daumenhoch:
Gotta get those graphite flanges fitted and while I'm at it I want to lose the bolts on a coaster Tuff and use rivets instead
I'll post any more info from my engineer as soon I as get an answer too

Nice one :daumenhoch:

The problem you guys will have here, is that you need an orbital riveting machine to fit them.
Its not like a normal rivet where the heads are bashed over, the press tool is rotating, on an angle about the rivet.
The machine allows for different speeds and pressures, depending upon the application.
Skyway used a Taumel Orbital rivetting machine.

So could they not be done by hand :(

this explains it all if it works :daumenhoch:

That's the exact answer I'm looking for . . . thanks Shaun :daumenhoch:
Making new rivets is no problem but the machine required to set them properly is another ball game and very expensive by the looks of that PDF download
Cheers guys

Yeah but there must be a machine shop or college that has one that we could use...
-
Good point Chris and at last we have the name of the tool we need to use
Getting hold of my engineer these days is almost impossible but I'll keep trying :daumenhoch:

Here is a pic of the head of the machine, to give you an idea.
If you know someone who works in a machine shop, you could get them to make the bush, with an angled hole, and to make you a rivet.
It may be possible to then use it in a pillar drill, there is loads of them around.

Iv got a pillar drill at work ;D

If we sort this out, bring your Tuff's round mine & I will sort them out ;)

i got one in me garage lol

As you know Chris i have replaced a hub using the old rivots , what i done was drill and tap the cut off end of the old rivot ,and used a bolt to fasten the hub in , the bolt was dressed to look like a rivot head , i wrecked a few rivots trying to get the holes drilled into the rivots as the wall ends up thin but it works , although i wouldn't go mad on it , its only for show .I have tried replacing a hub with steel rivots i had made , but it resulted in me cracking the wheel (just a old wrecker anyway) so be careful trying to press steel rivots in ! The other idea i had but never tried was to get some alloy rivots made which would be much easier to compress , but i wouldn't recommend thrashing them .

i reckon if it was just for show you could get a flat head steel nail and round the pointy end off with a ball pein hammer i wouldnt trust it to ride on though

This is the TAUMEL ORBITAL HEAD FORMING MACHINE which costs $7,500.00 in the States :shocked:

It looks like it's capable of pleening several rivets simultaneously

excellent...thats the one we need...buy two between us all
top stuff

Now that’s what I call a :bump:

Now that’s what I call a :bump:
Fook yea, thread revival and a half!! What's the deal here then??! Is that pic from the 80's?? Is that an original Skyway rivet machine?

That is an original Skyway Rivet Machine, photo taken in the past few years and is owned by Warren Eales in Country Victoria, Australia.
