Certainly the tube is 750mm long making it the same as a standard eq6 pro tripod at lowest setting , ordered from https://www.metals4u.co.uk/mild-steel/c6/tube/c2239/tube/c56/139mm-od-x-5mm/p8864 now phone up to order as you will need cut to length, you pay for a meter but they will email you the order then pay through link on email PLEASE state though that ends must be square cut as first order wasn`t very good but they sorted it pronto ,very good service ,
Base plate , top plate , and fins were ordered through https://www.lasermaster.co.uk/easy-order very easy to order, base plate choose washer type,material thickness 10mm mild steel 300mm dia then specify how big centre hole i did 55mm then in comments box i asked for six holes equally spaced 15mm dia, 35mm in from edge to centre of hole ,
Top plate as above washer type 10mm mild steel ,12mm centre hole 175 mm in diameter though i matched this to my pier plate (holes for pier plate to be drilled by me at a later date )
Fins x3 (i had a friend do me a drawing) chose rectangular 8mm mild steel 140mm x75mm i then sent a drawing in DWG format see attachments (there is three formats lasermaster use the DWG format )
Owl hole is 85mm in dia and 90 mm down from top of tube to centre of hole , and was cut using an 85 mm hole saw , i drilled a 6mm hole first through tube ,i already had holesaw but similar to this https://www.bltdirect.com/85mm-holesaw-drill-bit-accessory?adcid=pla&gclid=EAIaIQobChMI2diG0ZCa1gIVpr_tCh1cPQwlEAQYASABEgLYPPD_BwE you will also need the arbor aswell https://www.bltdirect.com/arbour-for-32-125mm-holesaw-accessory DRILL SLOWLY
