Recommend engineer, Tawa, tiny job

[pzkpfw]

Hi,

It was too late to add swingarm sliders to my motorvationusa order, and no-one seems interested in the ones I bought (for too much?) and turned out to be a little big, so I've to keep them and make them fit.

I'm a little un-co so probably should get a professional to do the job:

I need a flat spot ground onto the side of the body of the sliders. Just a mm or two deep, and about 15mm up the shank.

Any recommendations for an engineering workshop in the Tawa-ish area who'd do this kind of thing tidily but without charging more than the things are worth?

Thanks,

I don't know anything about anything Souf of the Bombays (is it even the same country?), but if you were up here in the land of the undead I'd recommend these guys to you:

They did a very good (and cheap) job of grinding a hard stainless steel tap for me http://www.kiwibiker.co.nz/forums/showpost.php?p=977580&postcount=36 . Old bastard who knows what he's doing. Of course that doesn't help you much, but might be useful for somebody else.

If you can explain in a little more detail what you want doing I maybe able to do it for you for nothing (have lathe and mill for machining).

That'd be awesome. With an "O".

Does the picture attached explain it well enough? (Can't find isometric view on PC and can't find compass in house, sorry).

Just need a flat spot (6 mm x 1 mm) put on the bike-end of the bobbin (claimed to be anodized Aluminium). The bit it screws onto is not flush with the side of the swingarm, and the bobbin is just slightly too wide. The slice to take off is to allow the bobbin to clear the swingarm and mount hard up against the flange (tag?).

I'd give it a go myself with a vice and my angle-grinder, but with the bobbin being a cylinder I'm sure I'd screw it up.

(The 1 mm deep slice is much less than appears in my diagram.)

No problem, though it could be easier to turn them down by this amount all the way round, up to you, if you just want a flat put on I can do that also.
I work on the Terrace in Wellington, do you work in the city?, if so I,ll e-mail you my work number and we can sort something out.

They're on (with some lock-tight) and fit perfectly.

They do clear the swingarm slightly - which sounded like a good thing (made good sense).

The "tags" they bolt on to are short pieces of cylinder - which are the same diameter as the shafts of the bobbins now are; looks good and in hind-sight is what I should have been trying for in the first place.

So - all perfect.

If I can ever return the favour please just ask.

Cheers,
