Best to find the straight, non-tapered section in the middle, that way one retains all the axle and brake fittings. Sleeves can locate inside or outside the frame, and should be tapered at the ends to prevent the stress all being at the ends of the sleeve.
This is something most anyone can do, except for bending the sleeves. All kinds of procedures are followed.
