as you can see...the bore for the HL axle is larger than the 21st century wheel...it was suggested to me ...to bore the hole
Clearly that was not a good idea... as boring the hole would have left a paper thin wall...and a weak axle mount
Luckily when I was in the hardware store purchasing the make shift spindle to spin the wheel... I also searched for a viable answer.. and found this
a pre drilled...white metal sleeve meant for crimping on hanger wire
...it fit perfectly... and the length was primo for making two axles

with just a tad bit of clearance... the axle bearings were cut to length...all twelve finished and ready for
installation
Happy Building
