I am now at the stage to start assembling my 10V, but have to drill and tap the studs , has any one got any tips on how i can achieve equal spacings and hoe to line up the stud holes on the standard to correspond with the ones in the cylinder.
Hope the above makes sence, any tips will be greatly appreciated.
If you have a mill with DRO then drilling using co-ordinates is probably the best way, it can also be done using the handwheel dials if you allow for any backlash. Zeuz book has the formulas for working out PCD spacings.
If You only have a lathe & drill press then one way is to make a simple jig. This would take the form of a "washer" with the 4 tapping size holes drilled in it, these can be set out by stepping out the spacing using dividers. Mark the washer with which side goes against the cylinder so any errors in marking out will not be an issue
To drill the cylinder & A frame you need a stub of metal thats a good fit in the bore and the washer and this will keep the two concentric. Clamp the washer to the part, drill tapping size and in the case of teh standard then open out to clearance.
