Looking good again Norman. As an aside, I've noticed in some of your builds you use pozidrive countersunk screws quite a bit, may I suggest you seek out some Torx versions next time you need to stock up on fasteners as the drivers don't cam out like they can on cross point screws. |
| Manxmodder:
Good work Norman,coming along nicely. I would second Arbalist's suggestion on Torx head screws as they really are a far better engineered screw driving head than any of the cross head variety.......OZ. |
| NormanV:
I agree with both of you that pozidrive are not particularly good. I am not familiar with Torx but my first choice would be Allen socket head screws. Unfortunately pozidrive is what I have and that is what I will use until they are finished. |
| Arbalist:
I try to avoid socket hex countersunk screws in the small sizes as I've had the sockets round off. This has required me to drill out a few fasteners. I believe the problem is that sometimes countersink screws can self tighten with vibration as I certainly haven't over tightened them. Just one random supplier of Torx screws: http://www.accuscrews.co.uk/32-hexalobular-countersunk-screws |

When I built a vertical head for my Aciera many years ago I did a trial assembly of a bearing retainer/seal housing with M6 countersunk socket screws. Two minutes later I couldn't get them out with the correct 4mm Allen key which ended up rounding off. I resorted to drilling the heads off. I used slotted screws in the end. The same can apply to button headed socket screws which have smaller sockets than a normal cap head screw. Phil. |
