The Equivalent North American Meaning of a Bare Fit

[carrdo]

Hi All,

LBSC in the construction article on the boiler blowdown valves I am making uses the term "a bare fit" several times in the text. Does this mean a close fit or...? Is this an English/Scottish term for all of you having a UK background?

I'd ignore it; it's a hang over from the days when most people didn't have access to micrometers but relied on plain calipers and rules. Just make it to size, or maybe a thou or two smaller if the part needs to fit in a hole.

It's prolly related to bare naked.

Perhaps the same as “Close Running Fit?”

"Just barely fits" ?

Or in your case "bear naked"

"Just barely fits" ?

So somewhere between a Locational Clearance and Locational Transition?

Might stand for "barely fits", "may need a hammer". I was told long ago when Easthope was putting engines together they had 2 hammers for installing pistons, the small one for "nice or loose" pistons, a 10lb. one for" tighter fits".

I would think that a blowdown valve would be a close fit
