Jennings pull question

[pj waelti]

I have a jennings gooseneck with a rockola jackpot conversion front. It seems to me the handle pulls hard. I have a couple mills slots and the pull is substantially easier.
actully I have a bursting cherry and a repro golden nugget that pulls like butter. Am I missing something here or does jennings just pull harder? Thanks PJ

I had a similar problem with a Pace conversion gooseneck. Adjusted the spin trip dog inward, and it helped considerably. That piece that's locked in place by the big hex nut and square head bolt. Moved it further away from the pivoting dog, simple enough.

will check that out thanks. PJ

Picture says it better

Tried that, but still pulls alot harder than my mills machines.. maybe I'm used to the longer mills handles? pj

Not the length of the handle I feel ... I am thinking an adjustment as mentioned the trip dog, might be needed. Also lubrication of the handle and its components could help too. All the parts that reset or move with every handle pull should be checked.

I guess I'll have to recheck my work..I did readjust the dog. and lubed all the moving parts that work when the handle is pulled.. the bad thing is I don't have another machine to compare with other than mills..pj

Are those pics of your machine? Looks like it has been blasted clean. If this is done to all the parts ( best if done with with Walnuts) then the whole mech will need to be relubed. Should of been done at the time of blasting. It could be very possibly why the linkage and ams are not moving freely.
Please let me know.

Those pics are two different machines I have. I didn't blast either one...both of these were remarkably clean when I got them, although the Duke was almost perfect, with virtually no rust on anything. Must have just got lucky.

I have another Jennings gooseneck 10c machine that is even cleaner inside, but it's one that got damaged by UPS, with a hairline crack on the top casting. So, eventually I'll find a replacement casting, and make that one 100%.

And for some reason I can't figure out, the handle pull on the 10c machine is easier than the same mech on the 5c machine shown in the picture. Otherwise, both mechanisms are pretty much identical.

My experience has been that an early gooseneck will usually pull harder than a Bursting Cherry or any of the Silent machines of the 30's and the early cast iron machines pull hardest of all. Once they are adjusted properly, they are what they are. The early stuff is just cruder than the later.
