Judging from the replies so far, there are not many DIY experts here.
What you are looking at is the average contact glue which is rubber based and thinner solvent. The glue must be spread thin and evenly fully on both surfaces to be stck together . A flat plastic spreader is sometimes suppled but can get from DIY shop. You do not squeeze the glue on without then spreading it out by hand...otherwise guaranteed it won't stick properly and airpockets will form.
When both glue surface are almostdry but still tacky, put the 2 surfaces together and apply some presure. The bond will be permanent.
BTW for this size of such a project do not buy the tube or cylinder type glue. Get the half gallon or gallon tin....far cheaperand easier to apply and spread. Youir DIY shop can advise on the best brand available for the job in hand.
Life is not about just playing drums....get your hands dirty some time.
