Fu tubes

I've just spent a happy afternoon repositioning my Fu tubes after realising I had fallen onto the steering column fouling trap.

Drew,

Don't know how far you've got and can't tell from your photo archive.

But it's worth leaving FU1/2 until your wishbones are done and you're attaching the wishbone brackets. As you've found FU1/2 are so hard to get right, it's worth using wishbone placement as your guide to get them right.

Making a jig as per my photo archive will help you.

Sorry if you've already got past this point and I'm teaching you to suck eggs!

Cheers,
James

Geez James,

You've so many pics/folders cand you give a clue where the jig is

Thanks for that Steve.

I missed Nige's post.

Don't let's forget maybe that's why uncle Ron called them FU tubes.

Thanks for the replies. James, I already knew about your jigs idea. Very good, infact I made one too. However, I positioned the bottom of the Fu toubes too far inward and the tops too much outward. The result was the bottom of the Fu tube fouled the steering shaft.

It's so easy to get them wrong . One of my brackets needed a bit of 3mm strip behind it to get it right- even with the jig!

Fitting the wishbones can help you get the brackets right, you can use a small line and plumb to get your 22*mm castor if you thread the string through the upper threaded BJ part.

HTH,
James

* assuming you're using book wishbones/dimensions
