Tascam 32 reel table wobbling / adjustment ? need help.

[fgonza2]

Hi, i am trying to setup my tascam 32. There is tape rubbing and a visible wobbling on the left reel. Not sure if this can be fixe only with height adjustment. Apparently the motor shaft is not bent. So there are five screws on the tascam 32 reel table; 2 that are perpendicular to the shaft, the ones the manual says to use for heigh adjustment, and there's the three on the surface of the reel table. So i remove all of them and the reel table won't come out. It is loose i can vary the height, but there is something blocking the extraction. So if anybody is familiar with this machine. i will appreciate your help, so my questions are:

1. Is this wobbling fixable ? or do i need to replace the reel table. The shaft is not bent (motor shaft)
2. How do i remove the reel table ? do i gain any thing by doing so ? to check if it is bent or not ?

thanks,

I had the same problem on some of my TSR-8's. The problem is that the reel table was machined out of spec from the factory, it is too tight, that is why it wont come off after you removed the 3 screws. It was jammed on at the factory and never seated correctly hence the wobble. Can you post some pictures?

i just closed the recorder. let me open it again and take some pics. But the pictures won't say much, basically the table comes out probably an inch or so, so i could adjust height if i wanted to, but it won't come off, looks like it hits something when i try to put it out. By the way i have a TSR-8 to that is in very good condition but the left reel wobbles as well. I will probably like to fix that one too but haven't tried to remove that one, how did you fixed yours ? any hints on how to remove the reel table and how to fix it ?

THanks

I used a Pulley Puller from an automotive store and carefully pulled the reel table of of the jammed hub. They can be remachined at a machine shop. One of them I fixed myself by carefully filing.

thanks, can you send a picture of the pulley puller that you used ? just for reference so i try to buy something similar. i am not familiar with those.

thanks

I may have some, I will look. I can see how the hub fit tight in the reel table, do you see the scoring/line where it was forced? That looks like the right puller, I put a screw in the reel table first for the center of the pulley puller to seat on. The way you have it the center part is pushing on the reel table and the 3 forks are pulling on it, you need to have the center part pushing on the motor shaft. I put in a screw in the hole but it wasnt threaded to the reel table, it just went in loose and seated on the motor shaft to provide the anchor point for the pulley puller. Well now you will know when it come time to fix the wobbly TSR-8 reel table. What are the numbers on your reel table?

yes, i know what you mean with the center and pull from by having support ob the shaft. That is exactly what i did, i used a long allen screw so it goes inside all the way until stopping in the shaft at the bottom of the hole. Used a lightly thinner screw so it doesn't get tangled in the thread. see attached zoomed in picture, where you can see it, it is the same color as the puller that's why it's hard to see on the original picture. So now i am afraid the TSR-8 may follow the same fate if i try this. Any other ideas that may avoid this situation ?

I don't see any numbers on the reel table anywhere, the only thing is that it says: "NISSIN" no other writings/numbers anywhere besides that.

Let me know if you have any of those reel tables. thanks

Oh I see, good thinking. So it broke because it was jammed on the hub so tight. I dont know why they continued to allow this to happen, They must have known they were jammimg the reel table on. I am pretty sure I have a reel table. I have to check when I go out to the studio today.

I found these 2, I have to see if they are spares or not. I have a friend on e-bay who might have some also.

Thanks, can you sell those to me ? would like to get two assuming it can be adapted also for the TSR-8. Can you PM details ? price + shipping ? or also your ebay friend. thanks a lot

removing reel table without puller

I found I couldn't adjust the left table height. The table appeared to be frozen on the shaft of the reel motor although there was no evidence of corrosion anywhere. I back out both set screws completely (more on this in a moment) and carefully injected a few drops of oil into the set screw holes with a hypodermic syringe and let it sit overnight. Then, holding the bottom end of the reel motor shaft firmly with locking pliers (use cushion on the jaws to avoid scoring the shaft -- there is enough clearance for side access to the shaft without removing the reel motor), rock the table back and forth pulling it at the same time. It may take a bit of force to get the table to turn on the shaft at first. Once you get it past the flat on the shaft, add a couple more drops of oil in one of the set screw holes and then work it off the rest of the way.
Polish the shaft with crocus cloth. Cut or tear a strip of 600 grit wet or dry and roll it tight so it fits in the bore of the table, add a few drops of oil to the bore. Use both a rotating and in-out movement of the wet or dry roll to lap the bore and remove any scores from the hardened motor shaft. Clean the bore with isopropyl or a flourinated solvent. Lightly coat the inside of the bore with oil and it should fit onto the motor shaft without too much effort.
Now, pick a set screw hole and position it over the flat on the motor shaft. Put the cup tip set screw in that hole and the other set screw, tipped with a spring loaded ball, in the other; this setscrew bears directly on the shaft diameter.

thanks for the detailed instructions. I used heat (with a hairdryer) and that helped remove one. However i have a second machine that has the same problem, will try the oil method.

Now, the problem that i have now is to remove the shaft holder from the aluminum table (where the reel sits). The shaft holder is where the manufacturing issue is on these reel tables are. so it has to be removed and rectified, but the shaft holder (the gray die cast piece) is so pushed in so hard that it doesn't come out, too much force will shatter it to pieces. Any ideas here ?

thanks

Can anyone tell me specifically what machining was done to the hubs? I want to fix mine.

Thanks,

Tom

take the reel table out. then separate the shaft holder from the reel table itself. Then take the shaft holder and put it on a lathe to flatten it on top and the sides, so it has a flat but snug fit back in the reel table.
