Making a decent bashplate

[Jeffrey SmithMember]

I wouldn’t worry about stress relieving it Blue, if you don’t get it right you will aneale the whole thing. Aluminium actually work hardens, that is the more you bend and shape it the harder it gets.

Another problem you can have bending it is if you overheat it, it will tear instead of bend. I had that problem at work once where I was bending 10mm Al around a jig with heat and it kept tearing, so I made the next one hotter and it tore even worse, so the next time I applied the minimum heat I could to pull it around with no problem.

sounds a bit light to me(street sighn) made one out of 6mm al plate for last bike and still cracked it but it was okay just welded it up .there are lots of different grades of aluminium and my b and b bashplate is 4mm and stronger than the one i made

spose you could put a black icecream container under there and call it a bash plate like ktm do

Quote “T6 temper 6061 has an ultimate tensile strength of at least 42,000 psi (290 MPa) and yield strength of at least 35,000 psi (241 MPa). In thicknesses of 0.250 inch (6.35 mm) or less, it has elongation of 8% or more; in thicker sections, it has elongation of 10%. T651 temper has similar mechanical properties.” Unquote.

I reckon it’ll do what da ya’s reckon, gunna try and make an integrated pipeguard with it too.

not promising any great shakes but I have surprised myself before…
