VR overhead movement

[DJ2000]

Hi All,

still trying to get to the bottom of the this groove break at the start of the record at 45rpm on 12in, anyone thats got a vr can they check is there play in the overhead where the two round bars bolt into the feed screw? i.e can you rock it front to back movement? mine seems to have some play and it will rock/tilt a bit front to back, ill grab a video tomorrow when down the shop but have attached a photo of the bars that bolt to the feedscrew for ref

Just a thought, your dashpot spring should have screw clamps on either end to ensure the spring doesn't move at all, otherwise I think maybe it could spin slightly changing the tension. That's how mine is anyway.

Film the bit you mean though with the movement, would be good to see exactly what Is happening.

yea noticed they are done with jublie clamps on now to stop the spring moving around although it dont move much over time, have done a vid link is https://www.dropbox.com/s/t2drfuk0uqmrzd9/20200719_102948.mp4?dl=0

Can't speak in general, but mine is tight. Definitely no play like yours.

It's quite simple to tighten it though (bolts below).
Or disconnect it entirely and see if there's a nut disconnected.
I've disconnected and reconnected it once, so it's easy.

wonder if its something worked loose inside where the feedscrew is as the bolts are tight from the bottom, anyone else with a vr can check is it tight or can it rock a little when you move it?

My advise is, disconnect the arm from the bar. It's 5 minutes work and then you know.

taken it off,looks like the play is coming from the brass tube that spins round the feedscrew inside the overhead

Have you tilted the VR to find out if there's a disconnected part?

The brass part is tightened with a white plastic ring on both sides of the brass part. Can you see if this is still in it's place?
The plastic ring can be tightened with (another white plastic ring with) two little screws. It's very difficult to get there with a screwdriver though.

Can you post pictures or a vid?

Mine doesn't seem to have any give, feels tight front to back.

Not to hijack the thread but is anyone familiar with how to remove the overhead for maintenance/trouble shooting?

[DJ2000]

its all back together now ill take apart and grab some photos am back home now though, I did see a white plastic ring on the end on the right hand side with a black screw in but i dont remember seeing anything on the left side though should there be one on each end?

so what do the white rings on the end do, never delved inside that on the vr before

another tight one, hrm mines floppy

you should be able to oil up the feedscrew from the underside thats about all i have needed to do with mine apart from this current issue, you can unbolt the bit that hold the head on from the feedscrew really easy but not so sure about taking the rest apart one end has a bearing in and the motor end has what i can only assume is white bathroom tile filler in?

*Knocks on wood* I currently don't have any issues with mine but I'd love to know how to do in case I ever need it. I've been oiling it from underneath so far and it's seemed to work but I worry about the day I need to dig in to the overhead/feedscrews itself.

Maybe I'm overthinking this. Could always remove the sidebars from the main plate to get underneath easier.

On the left there's no ring with screws. I think the only thing this ring does is by locking, making the brass tube actually move, I think. If it wasn't there it wouldn't move.

Did you try to power up the VR now it's reassembled? Maybe it was simply a matter of disassembling and reassembling which does the trick.

[DJ2000]

ah I see, so is it the white ring thats threaded and the brass tube screws to the white ring? i would have thought the brass tube was threaded, must admit I didnt pay much attention to the white ring on the end. will take it apart this week and check those screws

I did put it all back together yea it had play still, done a re cal on everything but had the same issue of missing groove in places at 45rpm have found one workaround and thats have a heavier head its over 20g not ideal but stops the break, I cut two 12in like this before left today

[Discomo]

Just a side question- do you find 45 drasticaly better audio quality than 33? I can't even do that because of severe wow issues.

[DJ2000]

not much dif that i can hear to be honest, i would have cut it at 33 but customer wanted it at 45

Ok. Perhaps it's because of the given plastic used for the blanks that there's no difference? Good subject for another thread

Can’t say for sure. But it would be an explanation for the wobbly overhead, if this part got loose.

Keep us updated when you know more

[Tinplate]

The wobbly overhead is normal and correct VR behavior due to the design of the machine. These white rings are sliders that work with the guide. The guide in this case is the outer pipe. They are made of PTFE or some other sliding material. Due to the weight of the head, they slide along the rear edge of an elongated hole in the outer pipe. If someone's wobbly overhead is smaller, it means that his/her machine may have slightly larger ring sliders, it has no effect on the operation of the machine. To solve your problem, try to check if the tilting head suspension works smoothly. Also, try loosening the spring in the oil dumper (by turning the plastic nut counterclockwise). Then set the stylus pressure again. Just theorize. Best regards.
