I was wondering where the rattling noise was coming from yesterday, found this this morning - I dont think im that hard on my bike, least not as hard as you off road riders are on yours. Must be flexy frames on these bikes. I just made a steel copy to keep me going for now.
I never thought to state where it came from on the bike Its one of the front ones, behind the front wheel. Theyre 4mm aluminium. Does anyone have a suggestion of what would be a good grade of aluminium to make some of these mounts from?
This is a mid strength structural grade available in small quantities. You don't want to get it hot cutting / drilling as it's heat treated. You could also look for a local company that does water jet cutting to suggest a grade and cut them when they next do a job in that thickness. https://www.ebay.co.uk/itm/Aluminiu...hash=item286b32394a:m:mwzeRlSnzwFkD-EYw8PbpUg
Perfect, thanks ill get both plates out of a 100x150mm coupon of that I can get them done without getting them too hot to touch
I dont think its frame flexing,more engine vibrations related. All other engine mounting bolts were tight? I have lost a few bolts and nuts in past...
Just got them finished this afternoon, took longer than i should have making them because i got a bit OCD getting them to match the originals, plus i wasnt in a great hurry to get them finished. I just sawed the basic shapes out, removed the bulk of excess with a die grinder with carbide burr then finished of with files I will put it down to vibration, ive had the top mount plate come loose before
