Hi Spinner,
I have been using needle awl machines from Campbell Bosworth ( Randalls and Campbells) for over 30 odd years.
Not running a mass producing factory anymore I have "stolen" 4 of the machines from those days there and have set them up in my custom shop. One thing I have discovered is that ( and I have 3 operating in my shop............ yes I know its overkill but I could do it so I did ) the Union Lockstitch machines without a doubt will give the tightest looking stitch of the 3 makes. The lock brake mechanism on these Unions is a much better "invention" than what is used on the Campbells in my opinion. It is this solid BRAKE that holds the thread tight during the lock.Im sure that Art , I and others could write screeds about these machines and their applications. I have had the Super Bull as well but after spending some time with it myself in the factory and having spare parts made for special applications, I just eventually gave up and it became another boat anchor
From what I saw on the internet ( I live in Cape Town SA) and write ups, I really thought someone had come up with a NEW alternative to the needle awl machines........ only to find out that it was just another OVERSIZED domestic machine from the East that was revved up but still had the same inherent problems as all the other needle machines out there. If you want a machine to sew leather just dont look anywhere else other than the needle awls machines. The needle feed machines are easier to operate but that is the only advantage I see. Price is another factor but if you can afford them . Go for it!! At the top of the game is the Cyclone but that sells for around 10K and over and has a waiting period. The Unions are in the 5 to 6K when I looked last.I have been waiting a year now:) Anyone out there own a Cyclone?
Take care.
