Perfect slide finger. Try different sized deep well sockets to find a good inside diameter. I found a 13/16 es perfect for my ring finger, but it needed to bend at that first joint to chord. I later moved to a copper pipe and cut a notch at the bottom to let it flex better on my finger, a trick I learned from a brass rock slide I have had for a long time: https://therockslide.com/shop/polished-brass-rock-slide/#tab-reviews Now those are great slides, and I still use it on my acoustic. But I moved to 8.5-40 strings on my electrics, and it was heavy enough to make me hit the frets regularly, so I began making my own with really thin brass pipe from Amazon: https://www.amazon.com/dp/B0DXQ4CSBW?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1&th=1 I have huge fingers so you might need 20mm or even 19mm. But that cutout makes all the difference. The final usable length should be about a mm greater than your 12th fret string spacing from the top of the cutout to the other end. That’s of course if you want to play all 6 strings at once (country blues and some really old delta stuff). If you don’t, then you can go even shorter. It for the price, you get enough brass for three slides, so go crazy. One thing to consider when you’re making it, start a half inch longer than you think you’d need, because if you use a standard pipe cutter, the ends will be rolled in and you’ll have some sanding. And if you use a hacksaw or a cutting wheel, you’ll still need to sand to remover the burrs. Thin copper will cut you if you leave the edges sharp.
