Help Needed - 15” x 6” Kelsey Hayes Wide Five Rim Repair

[Brian]

back in the 70's, here in New Zealand, hotrodders wanted wide wheels for their cars. there were companies that would spin the supplied rim[s] in their lathes, part off the outer part of the rim on the outer side, roll up some plate to suit the desired wheel width, and weld said ring to the wheel, and the parted off section of rim to the other side of the 'spacer ring' to complete the wheel. Indeed, I have repaired Kelsey Hayes bent spoke wheels with outer rim damage like you've pictured, by parting off the damaged portion and parting off the same portion from a good stock wheel, and welding the two together. dressed up, no-one would even know. [i could have widened said rims at the same time using the above method, but chose to maintain the stock width.
Another way to approach your job, would be to find other rims the same dimension as your current wheels, drill all the rivets out of both wheels and set up in a lathe the replacement rim on your wide 5 centre so it runs true, and with correct offset, and weld the two components together. i have done this operation too, but actually fitted wider rims onto my chosen centres [as opposed to using rings as described above.
