Guys I have a 2005 ballnut that i did the proverbial ball dropping trick months ago. I've just gone to put it back together to find that i still have all the balls, problem is one of the orange direction changing plugs is missing? I don't know how as i have not touched it. Can't find it anywhere. Does anybody have spare one going cheap from an old one they can sell me? i don't want to have to buy another nut for the sake of a plug :sorrow:

Cheers

Paul

I think you'll be lucky to find one, unless someone has an empty 2005 nut.

They're a tricky shape, but all the plastic bit does is guide the bearings from one channel, over one to the next... so it shouldn't be that difficult to make something that works. Would be interesting to try it, but probably best to just buy one.

Ive got that 1610 ballnut with most of the pieces your welcome to parts of that if its of any use. I suspect its entirely different though... being 16mm

The plastic bits are different sizes, since the channels they interact with are different dimensions...so assorted empty nuts are much help here. I've not got any 2005 nuts since it's rarely the best size screw to use.

Thanks guys, i have a working 1605 and check, the pitch is the same so maybe close? just hope i don't loose the balls out of that one finding out.

Ok just gone and had a look and the 1605 i could not risk taking it apart to look. What is interesting is the existing ones in the 20mm nut have 2505/1, 2505/2 embossed on the plugs. I will assume i have number 3 missing. The 2005 also has only 3 plugs and the 1605 has 4.? does it make a difference.

Gary if you are reading this could you shed any light?

Cheers

PS

the holes are the same size for the plugs on 16 and 20?

did you get them from me?
I have a box of about 50 nuts that need assembling, but are mainly the 1605 and 1610 size. are the ball returns blue or orange?

Hi Gary these are Orange and these came from the over seas shopping arcade i'm afraid ( too good a deal at the time). Do you see any difference between the returns (as long as the pitch is the same) from 16 to 25?

How come you have so many, do you dismantle them intentionally for cleaning? I've found that a surprising number of the one's I've had from China contain small bits of swarf, which is rather worrying.

I don't have many? The 1605 are on my router, the 2005 are for my mill. These have been spotless and the ones i've bought from Gary are definitely spotless. i lost the balls on the 2005 whilst transfering from the screw to some tube. I ordered a single screw with 2 nuts on it and needed to cut up the screw and mount it in the lathe.

As you have pointed out they are a load of crap and most of my time can be checking them and cleaning them.
Kind of given up on them now and will most likely discontinuing the Chinese ballnuts and standardizing on the better quality Gten range.
Its not just the swarf, but the tolerances of the balls, the crappy wipers and basic build quality.
