Dnk Posted October 24, 2012 Author Share Posted October 24, 2012 I was looking at the Starrett ones and they look like they should do the job nicely and not stupid money either. Link to comment Share on other sites More sharing options...
hackin_n_bashin Posted October 24, 2012 Share Posted October 24, 2012 Dunk, I wouldn't touch your bonnet with a hole saw, any way of you marking the holes, and popping over my way when your ready? I have a hydraulic press with a 20mm cutting tool that leaves a perfect circle. I would lend it to you, but we use it every day Link to comment Share on other sites More sharing options...
hackin_n_bashin Posted October 24, 2012 Share Posted October 24, 2012 Oh, and I've got 20, 22.5 and 25mm tools if you know the size Link to comment Share on other sites More sharing options...

Dnk Posted October 24, 2012 Author Share Posted October 24, 2012 (edited) The size is pretty open and purely to leave a nice radius instead of sharp corners. As long as i take it nice and easy a hole saw should do the job but i'll have a practice in the middle of the vent and if it doesn't work i'll give you a shout. I shall be going round all the edges with my die grinder afterwards to smooth out any roughness Edited October 24, 2012 by Dnk (see edit history) Link to comment Share on other sites More sharing options...
Ibrar Jabbar Posted October 24, 2012 Share Posted October 24, 2012 Cone cutter will do the trick if it's only 20mm, You can use my Snap On kit if you need mate. Link to comment Share on other sites More sharing options...
