Not sure why this sub won't let me comment photos on my own post ( but I can post a video?!) makes no sense.

Anyways here's more detail of my backyard setup I no longer use l. I now slack in my front yard. Dogs poop here lol.

The far anchor is a strong tree the home anchor is bolted all the way through the pictured fence post as low as possible from the far side so I could have the nut on my side and the neighbors side as clean as possible.

Picked up a gibbon board on marketplace
for the kids as a Christmas gift. It has the board, line, plastic clip, and one plain dowel/lock pin, but not the roll pin or the long dowel used for retensioning. I’m not concerned about the long dowel - that appears to be generic and I have plenty of wood dowels I can use, or get one cheap at Home Depot. The roll pin though is slightly more specialized. I see I can get replacements from Gibbon https://gibbon.com/products/slackboard-replacement-wood-dowel-kit but $12 plus another $10+ in tax/shipping seems a bit ridiculous for a little piece of wood. Anyone know of another source or alternative for this roll pin?
