Expresso front wheel rebuild

I just chopped through all the spokes on my front wheel with a grinder.
Bearing caps screwed off easily (phew),
bearings are showing some slight wear,
as I have never cleaned or greased them in 70 thousand kms they have done OK.
Then I cooked the hub on my Trangia camping stove,
its perfect, sits in there like a cooking pot!

The outer races fell out with a tap.

Now to get the hub to the sandblasters.
I'll try and get a before and after pic.

Later
Mal

Hi She'llbe, How ya doing?

tried Soda-blast'n the rear hub,
it won't shift nothing but paint!

I've read the stories about grit impregnating alloy and such and reckon its fooey.
Dismantled and blasted my own heads and barrels and engine covers and fork lowers about ten years back.
No different than riding down a dusty road.
Patient and very thorough cleaning stages is all ya need.

Mind you I'd prefer wet blasting but no one does that around here

cheers
Mal

Hey Mal, if ya don't get the spokes back in, yer cood always concrete the hub in place.
Those rims make fer mighty fine boxing.

Speaking of wheels, I straightened out a front wheel that I recently got from Germany.
I used a computer aided system I found in the shed.
My old computer tower was just the right height to rest a screwdriver on to use as a dial indicator. :mrgreen:

Crikey Jeff, that's gettin' a bit bloody technical. Whad'll people think?

Gidday Mal. Glad to see you taking an interest again. Speaking of proper procedure and wheel bearings, I've just epoxied the outer race back into Brunhilde's rear hub. It was good for about 8000kms last time I did it. I suppose I'll eventually get around to getting it sleeved, but it sure is nice to be back on the road again. My personal race-track to school is a ball-tearer.

Shit that is hi-tech.

:idea: Last time I did that I screwed a piece of threaded rod into the rock wall. (threads were never the same again :o )

Here is a soda blaster on the cheap for those little jobs, can be used on carburators and possibly other small parts.

I used that method a couple of times with surprisingly good results. I helps to be able to buy the 5# boxes of soda though.

I got by for years with the same trick Charlie, used a loctite product specially for bearings. Mine had so much clearance I wrapped a feeler gauge around it to take up the slack!

Thnaks for the article on the soda-blaster jagarra. Neat and cheap. I like it!

Harbor Freight has it by the 40# bag.
