....but i'm gonna try  ::)

So, some old KHE effort, that i came across quite a while back, and has been sitting in my garden for the best part of a year.

Before i got it, it had been sat in the original owners mums garage since about '98ish. One owner, never been apart from new.

And to be fair, wasn't exactly blessed with the best parts.

But being a tight arse, i'm gonna re-use what i can  :daumenhoch:

Pics.....

So, as you can see, pretty fookin rusty.

insectbones:
Stripping it down was easy, nothing stuck except the seatpost.

A squirt of WD40 in and around the post, and a jerry-rigged vice, consisting of a metal pole thats been there for 30 years if not more, and a stem placed in it, soon got it free  :)

And then into a citric acid bath it goes...

One thing i learnt though......cd chainwheels, in a CA bath....strips the 'grooves' right off of it...had a load of ginger pubes floating in the bath, and a wanked chainwheel....

This stuff, used 3/4 of the tub in the bath. don't know how many litres of water, but enough to cover the frame by a cm  :daumenhoch:

Most of the frame was clean by 48hrs.....but left it in another 12 hrs to get into the bad rust under the top tube/seat tube area  :daumenhoch:
