Equipment can be very basic. You could use a workshop hammer and a screwdriver, however I would not recommend using those tools. If you have invested in a barrel and a barrel program then please purchase tools that can help you get the job done safely and correctly.

The next step is removing the hoops. I like to start with the Quarter hoop. Position the chisel or hoop driver at an upward angle and give a few solid taps to knock the hoop loose. (Pic shows a re-install angle, just hit the hoop on the other side and upwards). Now is a good time to say why I like using a masonry brick chisel. See the red rubber square? It is going to save your hand from the inevitable hammer miss hand hit. Trust me, some of these barrel hoops are not going to pop off very easy and you will need to use a good hammer swing. You will miss at some point.

To reinstall after cleaning or repairing it is sometimes helpful to use a ratchet strap to slightly tighten the staves back up. This can aid in hoop re-install, but I would caution to not over tighten the strap. The staves can be seriously damaged or even turned out of position enough to cause leakage problems.

Putting the barrel back together is simple but usually takes just a bit longer than taking it apart. Some brewers will coat the edge of the barrel head with beeswax so when it is re-installed there is a nice seal into the Croze. This is optional.

There you go, pretty simple process but it is understandably a bit daunting the first few times. Once you do this a few times you will find your own groove and what works best for you. For more info on barrel care check out these to posts:

Polymorphisms in the human leukocyte antigen (HLA) class I genes can cause the rejection of pluripotent stem cell (PSC)-derived products in allogeneic recipients. Disruption of the Beta-2 Microglobulin (B2M) gene eliminates surface expression of all class I molecules, but leaves the cells vulnerable to lysis by natural killer (NK) cells. Here we show that this 'missing-self' response can be prevented by forced expression of minimally polymorphic HLA-E molecules. We use adeno-associated virus (AAV)-mediated gene editing to knock in HLA-E genes at the B2M locus in human PSCs in a manner that confers inducible, regulated, surface expression of HLA-E single-chain dimers (fused to B2M) or trimers (fused to B2M and a peptide antigen), without surface expression of HLA-A, B or C. These HLA-engineered PSCs and their differentiated derivatives are not recognized as allogeneic by CD8+ T cells, do not bind anti-HLA antibodies and are resistant to NK-mediated lysis. Our approach provides a potential source of universal donor cells for applications where the differentiated derivatives lack HLA class II expression.
