Or a web site that might help.If any body would like to see the drawning for clarity please email me and i can send it to you.

Conventions are different in various industries, but could it mean 'deep', like an X" dia. hole 1/4" deep?
Or, could you tell us what feature the 1/4" applies to?

dp on a drawing usually means "deep" as in depth of a hole. Could possibly be Diametral Pitch I suppose but not likely.

Thanks guys That makes scents. What the 1/4 referes to is C'BORE 1/2 x 1/4 DP., O' SIDE.
I am not sure what the O' is eather.
