Right now I'm so new I don't know what I want to do yet haha. Small items for now, not making saddles or armor or anything that big or extravagant yet. I'm working on a Vape case at the moment and plans to make a belt or two, a camera strap, maybe some dog collars and leashes, belt pouches. That sort of thing.
I have a slab of granite I got from a countertop store already. Currently I'm literally working off of a folding TV tray so vibrations carry quite well. That's why I ask if maybe I'm overthinking. Would just a solidly built bench be sufficient in itself to cut the noise? Also how thick for the plywood? 3/4" sufficient? I noticed that's what Spyros mentioned he used. Is that about right? overkill? underkill?
For holes I have a simple hole punch for my smaller rivets and snaps that came with my beginner set. I also picked up a cheap Rotary Hole Punch from Harbor Freight. I know I'll want/need better later on, but to get me started it seems to work ok. As far as holes for stitching, I haven't gotten that far yet really. I've got a set of 4mm stitching chisels with my set.
