| Cap bolt question |
| << < (2/3) > >> |
| AdeV:
Excellent, thanks chaps. I'll make the holes 16mm for now & either enlarge them or turn down the bolts if they won't fit. Look out for some sump progress tonight :) |
| buffalow bill:
Well, looking out for flying sumps, nothing here yet Ade. Still its only 6.45, time yet. :lol: :lol: :lol: Bill |
| kvom:
G-Wizard says 17.5x10 countersink. Head diameter is 16. |
| John Rudd:
So is this bolt a countersunk head or is it a standard cap head that requires a counterbore ? Gone to get me kevlar armour.... |
| AdeV:
Um, I suspect you're right John, I need a counterbore to hold the cap-head of the bolt... Damn these pesky machining terms. Look, I need a hole, that's big enough for the head to go into, but not all the way through.... the upright section is drilled 10mm clearance, the sump itself is drilled 8.5mm tapping (& then tapped m10) to take the cap-head bolt, that.... you get the picture... Anyway, a new sump post will be coming right up... just got to fettle the pictures & write the text. |
