@sammynq5 Correct, those aren't iron. You want
pancake plates. You should be able to fit around 4-5 10's per side with a 14" handle, so around 80-100lbs for the whole db.
I'd avoid any odd shaped plates with cutouts since you won't get as much on. I bought a couple of weird ones off Craigslist when I was just starting out and didn't know better, and they rattle and take up too much space.
Exactly, except the handles you linked are spinlocks. Those have threads, and the collars screw on to the ends and act like nuts on a screw.
Spring clip handles are plain unthreaded rod or round tube, and they use the grippy guys.
The spinlocks will work too. They're very secure, plus they come with collars. I actually have a Cap spinlock handle, the silver version of your link, and it's very solid. I just like spring clips better because it's faster to change weights, so that's what I use almost all the time.
It's all up to you. If you want to save $5, not have to buy collars separately, and get a slightly tighter fit, go with the spins. If you want faster and easier weight changes, plus maybe being able to fit an extra small plate on because of collar thickness, go with the springs.
Yeah, any 1" hole plate will fit. I got mine from Craigslist and Play It Again Sports. You want 4 2.5's, 4 5's, and the rest in 10's. Think the going rate these days is around $1 per lb for used. If money is tight, you can buy just enough for 1 db and do stuff like one arm lifts and goblet squats.
Pro tips:
- Double up on spring collars if you're doing any overhead lifting
- To get a really tight seal on spinlocks, put the db on the floor and spin the plates in opposite directions (handle will rotate clockwise)
- Later on, get another pair of handles so you don't have to change plates as much. Handles are very cheap at ~$20. Not needed for now though
- Always check weight limit before buying bars. Lots of snake oil in home gym equipment
- If you outgrow these, you can make 16-20" handles out of 1" cold rolled steel rod from a metals supplier website and a rubber motorcycle grip for the handle. But that's for much later
