Ratcatcher - Broken mono front fork

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Dear Sir/Madam

I have just acquired a Ratcatcher that needs a little TLC to get it back up and running.  The front mono fork tube has fractured at the top lug underneath the steering column.  My thoughts are to either replace the whole tube and re-glue to the lugs top and bottom or second option which might be quicker/easier would be to weld the old tube to the lug.  What is the best option and where could I get a suitable aluminium tube that will do the job?
Second point, one of the rear wheel bearings, in the lug at the back of the bike is grinding and needs replacing I believe.  Does anyone know where to get them from?

Many thanks & Regards

Daniel Vinson

	Please don't weld it!

	I'm not completely familiar with the design, but I guess it is aluminium tubes glued into cast aluminium lugs. A steerer tube is a very highly stressed component and welding aluminium will reduce its resistance to fatigue stresses. It may not even be a grade of aluminium that is suitable for welding. The heat of welding could also cause distortion and affect other glued joints. I would strongly recommend contacting Mike Burrows and ask his advice: 01603 721 700 WRT to bearings, www.simplybearings.co.uk are good. Either measure the existing bearings or ask Mike.
