Crimping too that doesn’t go tight enough

Hello,

I have a cheap Velleman crimper for BNC's but it doesn't crimp anymore like it should. I can press the handles against each other while the beak isn't closed completely. Is there a way to adjust this . See attachment for picture.

It is never a good choice to buy cheap tools.
My best recommendation is to buy a good tool. However it may be a temporary and not recommended solution: take out two pieces that come together to make the climp, and file out necessary in both flat surfaces, with a metal file to achieve to higher pressure
Good luck!

Hi there Guido,
Can you determine which part is worn or bent ?
If its one of the pins, it may be possible to replace it.
If the handles are bent, perhaps disassemble, remove the grips and straighten in a vice.
Is there a way to pack shims behind the jaws ?
Maybe pare down the inside of the plastic handles to allow them to get closer together.
Perhaps drill holes further out in the jaw plates, or closer together in the nose for the jaw retaining screws.
That's all my ideas for now ! I hope you may find something useful.

Hi Guido,
Your pic certainly shows the problem.
I will repeat the suggestions already provided plus:
1) If you have no other option - find where the slack or distortion has developed & attempt to correct.
2) Assuming you are a hobbyist & wish to avoid expensive pro quality tools; you could buy another low cost tool. In my experience they will do the job but they are less reliable & need vigilance to check that the crimp is always made successfully.
3) If this is in any way a mission critical application please do as suggested & buy a pro quality tool.
Good luck

adjust the ratchet and see what happens, the ratchet adjuster cam is the part just to the left of the upper yellow grip in the photo.

Thanks for the reply.
Of course it would have been better to buy better quality, but the step between a 25 and a 150 Euros tool is just not justified for hobby purposes. File out material is not what I need, on the contrary. I rather need extra.

Tried that already Sarah. It has only a very minor effect and I think it is just to put more tension on the spring.

In the mean time, I have removed the plastic on the handles and it seems to work again. Not nice but for the time being it has to do the job.

In the mean time I have bought this one :

Unbelievable cheap. Even if this wears out again after 2 years or so, it's worth the price. It's weight is the same as the previous one an it works great.
