Restructuring And Related Activities [Abstract]
Restructuring and Separation Costs	M. Restructuring and Separation Costs In response to challenging conditions primarily in the oil and gas markets, we have taken various actions during Fiscal 2016 to continue to align our workforce with future production requirements.  In Fiscal 2016, we incurred approximately $7.9 million of separation costs, of which $3.8 million were separation costs related to the departure of our former Chief Executive Officer in December 2015.  Additionally in Fiscal 2016, we incurred approximately $0.5 million of restructuring costs related to a Canadian facility that we leased and exited in the third quarter of Fiscal 2015.  Of the $7.9 million in separation costs recorded in Fiscal 2016, $6.8 million has been paid and the remaining $1.1 million will be paid over the next fiscal year.   In Fiscal 2015, we incurred $3.4 million of restructuring and separation costs.  Of this, $2.6 million were separation and severance costs associated with headcount reductions in Canada and certain U.S. operations, as well as the departure of our former Chief Operating Officer.  The remaining $0.8 million was related to the exit of one of our previously occupied leased facilities in Acheson, Alberta, Canada and the write-off of associated leasehold improvements.  The lease does not expire until October 2019; however, we have sublet the facility through the remaining term of the lease.
