Case Savers questions
 

Dear all,

if a case saver outer diameter 14mm x 2.0 will be installed in a 7R housing
isn´t there a risk that the cylinder gasket flange get to narrow.

These kind of case savers as listed at pelican requires a tapped prepared bore.

Is the process as followed.
Bore 12.1 mm and the use a three step tap and perform the M14 thread. But a M14 metric has a slope of 1.5. Why has the case saver a slope of 2.0

would be a 13mm be enough. That would leave 1,5 mm wall thickness.

Hope you can brighten my mind.

It does get close to the edge by hand, if you use a mill you can cheat a little and give yourself a bit more room, I have 14mm taps from 1.0mm to 2.0 pitch, nothing really odd about that?

hello
that's what i've done
i asked the same question a few monthes ago, worked fine

Thank you Phillip.
Was the outside diameter M14 x 2.0 for the case savers.
And do you did the work.
Did they use an interference bore or tapped M14 and with loctide glued in the bold.

hello
a machine shop did the job
they tappered to fit a M14x2 case saver. (first bored to diameter 12 and then tappered)

And did you never thought that the surface for the cylinder foot gasket gets to small.

The this copper ones.

that's rather small, but that works
you may ask another people, i believe they'll tell you this is a "common" operation.
