Topic: wheels laced up inside out

[Scott]

Hi there
I just got my wheels back from the bloke who laced them up for me.
He got the spokes that normally come on the outside of the hub on the inside instead.  And vise versa.
Does this make any difference except for looks

Thanks
Scott

Hi Scott,

The inner & outer spokes have a different bend to them at the head. If they've been installed incorrectly I would rectify it now, before going any further. If the spokes are over stressed they will break. Who did the work for you? It's hard to comprehend how they could get it wrong??

If you can't get original wheel builder to fix his error, I can recommend 'Chivo's' at Parramatta. He does a great job at a very fair price.

Are you sure?  because that is almost impossible to do without bending the spokes....Larry

[Scott]

I'll take another look more carefully this time and see what I can work out.

Also the rear wheel wasn't drilled properly so those spokes are slightly bent, more of a curve really

I did the same kind of thing the first time I laced a 500 wheel.. without breaking any spokes.... as pictured
It was impossible to true it and get spokes all to same tension

eh !!!!!  ... was this a stock hub .. if so I can believe it wasnt drilled correctly

[lucky]

Better do it right.
When the brakes take hold, a lot of force gets applied.

If the stock rear hub was used with a new rim, it could have been a rim drilled for discs instead of drums.  That would be alarming as well, as the
spokes would be bending near the threads.    Still hard to believe that a rim builder would mix-up the spokes - but, it happens.  Definitley get that
thing double-checked.

if you starts in the vrong hole..then vill the spokes direksion be different..there are often  wear marks from the spokes in the hub..so they have to line up to the old spokes..odervise the wearmarks can be seen

[strynboen]

all spokes sits korrekt..its just the hub..who are turned one hole

[Jayelwin]

What bike are we talking about? I've got brand new DID rims and spokes for my '74 CB750 and I'm starting to panic.

[Scott]

It's a CB750 K2.
When I put the new wheel up against the existing wheel on the bike the way it should go (bearing retainer on the left) the spokes are coming out from the wrong side of the hub. The hub to rim angle on the spokes is fine but it is just the way that the spokes exit the hub.

Now if I turn the wheel around so that the bearing retainer is on the right hand side of the bike every thing looks OK

[Scott]

The rear rim was drilled slightly wrong from the place I bought it.
It came from Central Wheel works in the UK.  The guy I originally sent my wheels to here in Sydney for lacing pointed this out and said most dudes would just put them together anyway.  He wanted to counter sink the holes so that the spokes would not have a curve in them near the rim.  After having my rims and hubs for 5 weeks and not making a start on them after promising to have them done in 2 to 3 weeks I went and picked them up and took them somewhere else.

This bloke put them together for me in one week and was alot cheaper.  So if I can get a photo of the curve I will post it up here. It doesn't look too bad to me but I'm not a wheel builder and the first guy who is an expert didn't say they must be modifed, it was just that it would look beter as I understood him

It is very easy if you do it in the right way with new rim and spokes. Just  tighten them evenly step by step around the rim and measure the result with a marker pen + dial indicator wheel spinning on its axis.

Start with the spokes that enters from outside on both sides of the hub and rim. Then the other enter the hub from inside.

Scott,

The link that PeWe has given above is awesome. I used that same reference when I laced up my wheels. It was easy following the tutorial. Can you post up a picture so we can all see the problem? The spokes should basically be 'grouped' in lots of 4 if done correctly. Whereabouts in Sydney are you? Like I said earlier, Chivo's are great to deal with, very old school service.....I laced them up & then Chivo trued the rims & fitted Metzeler tyres/tubes/rim tape/balance etc all for about $240-280?/wheel from memory. Did them in about 3 days too!

[PeWe]

Yes, that thread helped me too when I got problems to get it right. I could not figure out what I did wrong since I had done it several times during the 80's. Important to start with correct spokes. If not the spokes will block each other.

The rims have sharp edges where the weld is grinded on the inside. I sanded the edges and painted with what I had, silver spray. I think I reduced risk for flat tire.

EDIT: I used 2 car axle stands for the wheel axis when truing it.  The wheel between them.

[iron_worker]

The spokes should NEVER have to bend. You're inducing a LOT of excess stress on the spokes this way. The spokes are very strong in tension but very weak in compression and bending. I wouldn't even think of running it like that. You're just asking for your wheel to fly apart at high speeds. 

Besides the fact that truing the wheel will be next to impossible like that.

Thanks Disco
Sorry for the slow reply Fridays get a bit rushed around here sometimes.

I've used Chivo before and agree he is a good bloke and a fair price.

Now if I was to talk about the spoke next to the tube valve hole going in a clockwise direction looking at the bike from the right.  This spoke on the new rim is laced up to the outside of the hub using the spoke with the sharper bend (90 degree bend) where it enters the hub. 

From my understanding this is the correct type of spoke to use on the outside of the hub.  The problem is that this hole position on my old rims goes to the inside of the hub

Hi there Iron Worker

I'll try to get a photo of the curve in the rear spokes.  I struggle more than anyone in history trying to get a photo from a camera or phone onto the computer, but I think this one is worth the effort.

I've got to go to work now and will make an effort when I get home to post the picture.

Thanks heaps for replys so far.  I appreciate your time
Scott

Thanks PeWe
I took a quick look at that thread link and I will have a proper read soon.

Thanks for your time
Scott
