Default Metal cutting bandsaw blades

Yes Dave the nominal blade size is 1700mm I can get 1715mm for wood
from most
anywhere its quite a common size but cant seem to find any metal
cutting blades this size
Ive a job to do which involves cutting some 1/2 alum plate been advised
to try 6-10 TPI wood blades however I tried a brand new 14 TPI wood
blade last night this lasted for 3 or 4 straight cuts then the cut was
like spagetti junction.So i would rather get the tool for the job .The
ajustment range is not enough for 1615mm and I can see that this is a
common size for metal cutting from your web links. Think I will have to
find somewhere that will make half a dozen up for me.

I'd bet a nickel that those 14 tpi blades were jammed right full with
overheated aluminum as a result of being unable to clear the chips.
Makes for a poor cut.

Have you actually tried the wood blades at wood speeds? Try a 4 or 5
tpi blade running fast and see if it does not work as well for you as it
always has for me. Three teeth in the material is a great rule of thumb
to use on a gravity fed saw, but with a reasonabble person running the
saw (and not ramming the stock into the blade) the coarser pitch works
very well indeed. Have you a table saw? They work very well too.
