Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
The Sefar roller frames mentioned are a prime example. I've got 6. One bolt or the socket it screws into has stripped. Other sockets were too shallow, either from insufficient tapping or from flash from the casting clogging them up. Had to put washers under the bolts, which then can interfere with the adjacent bolt.Savings? The price of the Sefar frames are only a couple of bucks cheaper than a Newman. I've got some 40 Newmans and I've never had a failure from any of them, either old blue ones or the dozen new ones I've bought.Suspect until proven is some sage advice, GD.
I've got 6 old Diamond Chase frames I've had for 9 years and have worked well enough. I don't think the threaded ends will sustain 40 ft/lbs of torque, but mine have held up so far. I was gonna sell them but I've got enough 86 mesh laying around to stretch them and I'm gonna use them for plastisol number transfers.
The newer Newmans are junk ( I stripped out 2 of them) and you can add Chase Diamond to the crappy roller frame list too, the actual bolts snap off and are a pain the butt to get flat. The old heavy blues are the best!
Surely the machine doesn't infringe on any patents, but if it does, there is pecedent set with Tajima versus Feiya. It's not legal precedent in the way we usually think of it, but it's persuasive at least. These two scenarios seem to parallel each other to a great degree, assuming the china sporty is as much of a copy as some might suspect.http://www.tajima.com/articles/details/03/14/index.html

Do the two scenarios seem similar or am I reading something into this that isn't really there. I personally think they are almost carbon copy scenarios, one being an embroidery machine, the other being a screen printing machine. I guess more needs to be known about the Chinese press and if it infringes on anything, but from the outside, it sure looks like it does. I'll go ahead and give the benefit of the doubt though and maybe the China Sporty only looks similar to the Sportsman.
