Nice one Ginge, looking good, the seat back is fun as you feel you need three pairs of hands all at the same time
i hope you don,t mind me asking but has the build table dropped slightly under the nose area of the chassis? as there seems to be a small gap between the table & the bottom rails at the front end , might be the camera angle too,
as for fully welding, its best to leave it until you have all the diagonals & the "RS" parts tacked into place, also make sure you alternate where you fully weld, go from side to side/front to back etc to minimise any heat distortion from fully welding
when you "think" its all fully welded i,ll bet you a pint you,ll find one you missed
i know i did
nice progress, i bet the kids & Mrs are impressed.
