I found that black ABS (as supplied by MB) needed a higher temperature to make it bond to it. But when it did bond it would bond so strongly I ended up using chisels, but still ended up destroying base after base.<br /><br />When it comes to drilling the aperture, I've found the method that leads to the fewest micro-drills breaking(which tends to leave a chunk of the drill bit blocking the hole it has drilled). The way I do it is to drill a hole about a mm deep, and if this isn't deep enough to break through into the 3.5mm hole on the other side. Then use a disc sander to wear away the surface until the hole just drilled is almost gone, then try again. This way the hole depth is kept to a minimum and you don't get constant drill bits snapping off.Peter Hillierhttp://www.freeasinsteins.comnoreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-65413246490608056542010-05-24T17:03:05.049+01:002010-05-24T17:03:05.049+01:00No I sort of drill as far as I dare because if I g...No I sort of drill as far as I dare because if I go too far it is ruined and it is not easy to measure. My guess would be a longer final aperture would increase the pressure for a given feed rate so would increase the die swell. <br /><br />I did experiments a long time ago that showed that smaller apertures give more relative die swell when other parameters are the same. I have never been too sure what the effect of the length is though.nopheadhttps://www.blogger.com/profile/12801535866788103677noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-63611433498088167672010-05-24T16:35:57.621+01:002010-05-24T16:35:57.621+01:00Thanks for another very interesting post.

Which (do you think) is longer? And which has the higher length:diameter ratio?Leo Deardenhttps://www.blogger.com/profile/04947654308614394044noreply@blogger.com
