Wheel rims scrap?

[Simon_Head]

Hi

I am a newbie to wheel building.

I probably have done something wrong in having some conloy constrictors rims polished before wheel building. It looks as if this process has distorted the rims.

There are no kinks in the rims but a wheel builder says they could not be built into wheels as they are not round true and not lateral true. He says that this could not be resolved by wheel building.

Is there a pre process available to re true them both circular and laterally prior to wheel building?

Or should I just take his word and scrap them?

Any comments totally appreciated!

Kind regards

If they are oval then the spokes will pull them round, a little bit of manipulation beforhand can help. put cushion on the floor and press down on the top of the oval to make them more round lateral twists do the same by applying opposing force.. I'm not sure what the wheelbuilder is saying ? Supercahmpion medale D'or came from the factory nowhere near round!

Polishing might have over heated the rim and distorted it locally, so lots of small distortions. These might not be possible to pull out by building. Measuring carefully and manipulation *might* bring it back, but i guess your builder is saying that the time taken for him to do it would make the build far too expensive (probably more so than the value of the rims).

Have a DIY at rounding them up, it'll not cost you anything, then see if he'll build with the freshly straightened rims.

Failing that, try a better wheel builder, there are a hell of a lot of them out there who merely assemble the components rather than actually building a wheel.

Re:

He sounds like he's talking rubbish. They polish up really well and are strong rims. They can be built to be true. Make sure there's no dents in the braking surface and you need to use spoke washers with spokes. Check the join and rivets are ok and not loose. Depending on where you are there are a number of good wheel builders around.

Re:

Thank you all for your replies.

A couple of them were new old stock- the rivets and braking surfaces were excellent. Does anyone know of a good wheel builder in the Manchester area who could sort them out?

I also have some Dunlop light weight stainless wheels I think could also do with the same treatment.

Thanks

On my Roger Queen build I used the same rims had them polished & they were distorted but once built they run very true & these were 28/28 combo. If you not building them yourself make sure you get a good wheel builder with a good track record & knows what he's doing.

Anyone know of such a wheel builder in the Lancashire/Cheshire/Stoke area?

Hello Simon,

First the SS dunlops: If you have a flat surface to check them any deviation from the surface will be very difficult or impossible to correct. It would mean that have either been accidentally damaged or perhaps someone chopped the spokes out when the wheel was fully tensioned. A bit of up and down deviation should be OK.

The Conloys were always lumpy and varied in width, I was not surprised when they closed. Careful work can improve them, but they were never very true in compared with the expectations of a modern user.
Not helped by the problem of fitting 5 speed block in a 4.5 inch rear end, which meant the gear side spokes were nearly vertical.

A worse problem was having to stuff the well of the rim where the tube had to expand down the narrow gap between the wire beads. There was a tendency to blow holes in the inner tube which got worse when we had butyl tubes in the mid 50's.

This is part of the reason why tubulars were used then. My first tubular tyres in 1949 were Constrictors on beautiful laminated Maple rims, I rode these in all weathers. Look up the old catalogues, these had no stitching.

Some of you may know I was a retailer and repairer from 1954 to 1966, and personally built thousands of wheels.
