Izidingo eziyinhloko zekhoyili yokungenisa engamathani angama-50 esithandweni somlilo esiphakathi:

1. Izinto zekhoyili eziyinhloko: 62x50x10 ithubhu yethusi elingunxande, ukuphenduka okungu-32; ikhoyili elisizayo? 50 × 4 ithubhu yensimbi engagqwali (304), 3 ijika phezulu nangaphansi

2. Isikhala sembobo sesikulufu sokubopha ikholomu ye-bakelite kufanele sihlangabezane nezimfuneko zomdwebo, futhi iphutha lokuqoqana ngu-≤±2mm. Isikulufu sokubopha siyithusi M16x105

3. Insika ye-Bakelite 2 iyihlangothi lokungena ikhoyili, ucezu olu-1, kanti okunye kuyizinsika ze-bakelite 1,17

4. Amalunga amanzi okupholisa ikhoyili angama-?45 pagoda joints, ubude 150; imibuthano emithathu engenhla nephansi yenziwe ngensimbi engagqwali engu-304, ethambekele phakathi lapho ishiselwa, elungele ukufakwa kwepayipi, kanti enye i-T2 yethusi.

5. Ikhoyili kufanele iqinisekise ukushintshashintsha kokufaka nokusebenza kukagesi.
