Hi,
I thought I would share a conversion I did to a normal board bag to make it a roller bag as I couldn't find anything in any of the shops.
Might be of use to a few people.
I just used 2 old roller blade wheels/the bolts from the roller blade, some alloy channel, small piece of ply & a few screws
Took about an hour to cut cut the bottom wall out of the channel so the wheels would fit & fit everything together, didn't cost anything as I had the stuff lying around in the workshop.
Not meant to be pretty, just stop the airport staff dragging the board around
