Would 18 TPI be ok for cutting the chassis or too harsh?
Cheers,

Hard going through thin wall. It'll cut quick, but you'll struggle to keep the line. Use 32tpi, more effort but better cuts. I use a variety of angle grinders myself, both 4.5 and 9 inch, lot easier on the forearms.

Thanks - will look get some 32's and 24's.
(But think of the benefits of strong forearms!).

24 tpi are common (can be found most places like 18) and seem to vety work well on 16 swg from my past experiance.

I used multitooth ones, the teeth vary from 18 to 28 over every inch, they seem to stay sharp for ages and you can use them on almost anything

The usual rule of thumb is at least 2 teeth in the piece at any time, so for 1.6mm (1/16" ) you'll need 32 tpi.

...I left out the "preferably 3 teeth" bit of the recommendation! Even at an angle, you'll only get 2 teeth in the work on 1.6mm stock.

Dave - you just know it's coming...

Oh yes...

I use 24 tpi.. Work well i find. Worth getting good quality blades though.

I tend to prefer a nice coarse 18 which rips through the stuff really quick. A bit of tweaking on the bench grinder is sometimes needed afterwards but this is less painful than spending twice as long cutting in the first place for accuracy (only to find you still need to take it to the bench grinder!).

The good thing about finer blades is that there are more teeth to break off the blade before its unuseable, whalst you learn to handle a hack saw.


By the way 10 tpi and a hydaulic damper to control the blade, I think a bandsaw is on the wish list, 16g stands no chance.

Also a lot easier to cut square or mitre accurately
