making wheel spacers

#1 Post by oldmadbiker » Sat Sep 01, 2018 3:15 pm

hi all...i need to make a wheel spacer for a project im doing....
i was thinking of using aluminium tube and cutting using a mitre block....
looking online at tubing and they all state outside diameter...i want 25mm id so thats confusing me...
if i find a tube with 28mm od and a 3mm wall with that give me the 25mm id i need...
or should i find an engineering shop to make them for me....
cheers all

You need to do the maths again 28mm minus 3 minus 3 is 22mm

you know i was just thinking that......my head hurts
so if i went 28mm od with a thickness of 1.5mm i would end up with what i need.
is it ok to make it out of aluminium

Wall thickness of 3mm sounds a bit thin for a wheel spacer especially out of ally?

Depends if it is a "spacer" or a "sleeve". If it is a spacer, then I agree, 3mm sounds too thin. But there again, we don't know what it's for.....
Oh my God, what's happened? I don't know man...I just got here myself!

I would also say 3mm is too thin. 1.5mm (post above) definitely too thin

Best way is to get an engineering shop to machine to size out of mild steel.


(all the specares I have sen are steel).

Anyone with a lathe can turn these in stainless for you . I definitely wouldn't use aluminium for a wheel spacer .

measure the inner diameter of the bearing dust seals for external diameter of spacer

But I have promises to keep,
And miles to go before I sleep,

:stupid:

Measure inner diameter of dust seals for the OD of the spacer and measure the OD of the spindle for the ID of the spacers

You need to do the maths again 28mm minus 3 minus 3 is 22mm
However, as it is Alloy and liable to 'squash', then you would need to take the maleability into the equation: OD - (2x thickness) x~ (I don't have the correct symbol for the 'squish' factor) = ID :?

Your hair could get caught it it , this happened to girl I knew . I've never been comfortable around wood and metal working machines. Band saws give me the fear just thinking about them .

Me too
2018 BMW R nineT
“It’s shit. And as soon as I get home I’m going to buy one.”
That was a fellow journalist’s first impression of the BMW R nineT recently. It’s a pretty accurate summary; the R nineT is somewhat ill-mannered by modern motorcycle standards but also instantly, inarguably, infatuatingly wonderful.
