Home made frames

Oh so it was actually an old Raleigh frame in the first place then?? blimey, I thought you made the hole frame.

must've been tricky trying to put on a sliding dropout/disc mount on an old steel frame that doesn't know such thing exist in the first place.

how safe it is to weld in a disc mount on an old fork?

With a bit of reinceforment for ladys riding style should be ok
but in general it dosent sound safe...
The frame has got new chain/seat stays
