Slider-ka caaryada balaastikada ah guud ahaan waxaa laga samayn karaa bir 45# ah, kaas oo la damiyo oo la qaboojiyo si loo kordhiyo iska caabbinta xirashada. Booska tiirka hagaha ee u janjeera wuxuu ku jiri karaa hore ama gadaal, kaas oo si dabacsan loo go'aamin karo iyadoo loo eegayo cabbirka caaryada. Si kastaba ha ahaatee, xagasha iyo dhererka tiirka hagaha ee u janjeera waa in lagu go'aamiyaa iyadoo loo eegayo masaafada dhaqaaqa ee slider-ka; guud ahaan, xagasha tiirka hagaha ee u janjeera waa 20° ama 25°. Go'aaminta xagal go'an waxay fududeyn kartaa soo saarista birta u janjeera ee u janjeera, si looga fogaado baahida loo qabo mar kasta. Si aad u sameyso geeso u janjeera oo leh xaglo kala duwan. Isticmaal sharciga cosine ee hawlaha trigonometric si aad u xisaabiso dhererka tiirka hagaha ee u janjeera.

Waxaa jira noocyo badan oo daawayn dusha sare ah oo caaryada ah, kuwa caadiga ah waa dusha siman iyo dusha sare ee calaamadaysan, kuwaas oo ah saamaynta dusha sare ee loo baahan yahay in la sameeyo iyadoo loo eegayo doorashada macaamiisha.
Heer kasta oo dhammaystir dusha sare ah oo warshadeenna ah ayaa la isticmaali karaa.

Saldhigga caaryada caadiga ah macnaheedu waa in saldhigga caaryada laga sameeyay walxaha P20, caaryadana laga sameeyay tignoolajiyada muraayadda. Guud ahaan waxaa loo isticmaalaa caaryada dhoofinta. Faa'iidada isticmaalkan ayaa ah haddii ay jirto dhibaato caaryada, si fudud ayaa loo hagaajin karaa iyadoo la beddelayo qaybaha, taas oo ka wanaagsan.
