Bonded tubes looks great but connection is not strong enough. I prepared connections for laminating extra layers of carbon fibre. I removed sharp edges using filler. Filler is created by mixing epoxy with microbaloons (microscopic glass balls):
Next connections was strengthened by carbon fiber (nylon tape was used as press and after curing removed):
For ‘cosmetic’ reason I continued using filler and sanded connections for nice looking shape. It is important to sand only filler and carbon fiber leave untached:
