Adjustable Leather Stitching Pony

I designed this because I really wanted one of those fancy stitching ponies, but I wasn’t about to drop $180+ on one of the adjustable ones, lol. I started designing my own. I wanted something compact but feature-rich: built-in magnets to hold my needles, smooth surfaces that wouldn’t catch or tangle my thread, and handles that stayed out of the way. After a few iterations, this is what I came up with - a pony that works with me, not against me. That “hole” in the front is there for a future addition. I'm going to be adding a handle extension to hold large pieces of leather out of the way. There are a lot of moving pieces here, I hope this helps you piece it together the right way. Most of my hardware I purchased from Lowe's, but I'll get you as much information as I can so you can buy your own: Parts: 2x: 9mm x 35mm Compression Spring 1x: 3/8-16 Hex Nut 1x: Hillman 3/8" x 3" - Half Thread Hex Bolt 2x: 5/16" x 2 ½" Hex Bolts 2x: 5/16" Hex Nuts 1x: 1-¼" Aluminum Threaded Post 1x: 1" Alu
