Cutting RHS lengthwise

mardi 16 décembre 2014

Greetings all,



I needed to make some "U shaped pieces" that were 75 mm wide, 100 mm tall and 125 mm deep (6 mm thick).

To do this I cut 125mm long pieces from some 125 x 75 RHS and then cut them lengthwise as shown using my trusty little horizontal bandsaw.



So that I could leave it cutting unattended, to stop the blade just falling through the gap in the middle I packed the gap with a piece of wood.

What surprised me was how long it too cut through the wood, and the resulting fine soggy wet sawdust clogged the filter on my coolant return line so that the coolant/lube came close to overflowing the return tank (a length of household guttering).



I'm just wondering what else can be use in this situation.

I could have stood the block up onto its narrow end but then my saw wouldn't have done it in one pass and I would have had to flip it over.

Thanks
