Interlude #12: The Making of the Hook Stick Extension Grabber Thing | In The Lab With Jay Jay

This post is part of my video blog and you can find more information about this video over here.

You can support this channel on Patreon: patreon.com/JohnElliotV

In this video we put a hook on a stick so I can reach stuff that is high on my pegboard.

In this video I mention Ali the Dazzling and the Star Wars Kid. The wood shop channel I enjoy is Workshop Companion.

We use the Deep Hole Long Nib Pen to mark the points for drilling.

We use the Rockwell RD2971 18V Drill Driver Kit Drill for drilling.

We use the Bosch IXO VI Electric Screwdriver to drive in my screws.

My pegboard hooks are these ones: HORUSDY 120-Piece PegBoard Hooks Set, Peg Board Assortment 12 Different Types of Hooks for Garage Organizer Bins Shop Display Hanging.

We use the 14500pa Cordless Hand Held Vacuum to tidy up after ourselves.

We use the Yum Cha 10pc File & Rasp Set Metal File for filing.

We use the Plato Model 170 Wire Cutter for cutting our string.

The KVM I mention toward the end of the video is my AOOCOO 4K@30Hz HDMI USB 2.0 8-Port HDMI KVM.

If you’re interested in HDMI specs there is heaps of info on the Wikipedia HDMI page.

The monitor I mention toward the end of the video is the UPERFECT 15.6″ HDMI LCD. It’s physically small, but high resolution. I stop using this monitor because I was having trouble making it work with my new KVM and my studio workstation ‘verve‘.

The new component drawers I am getting for the new space on my pegboard are these: Jaycar HB6330 33 Drawer Parts Cabinet
