Tape lifter sleeves

[cjacek]

Guys,

If you were to illustrate the tape lifter sleeves one needed to make for your tape recorder, how technically would you do it, considering the rather low tolerances of such a task? How would you accurately describe the diameter of each lifter, for instance? I just can't see doing it with a measuring tape... If you were to make a mold of it, for example, how and with what would you do it, as that strikes me as a more sound option (at least for the diameter)? Any other tips on how you would get the tape lifter diameter down and accurate?

THANKS!

Calipers!

Every engineer has calipers lying around!

Thanks Dave!

Then I guess I'm not a true engineer! I'd better get me some of them calipers then!

Seriously, are all calipers created equal, from an accuracy of measurement standpoint ? Which ones should I look for ? Would an electronic readout one be recommended in favor of the others ..... ?

Digital calipers are more accurate, but analog calipers are warmer.

Haha, got'ya!

Nah, they're both relatively equal, but it's not the instrument, it's who's using it!

Got'ya again!

Hehe

Yeah, so it's mostly a matter of convenience then? Any typical caliper would work?

I have analog calipers, of course, but...

either type should do the trick!

Thankyouverymuch!

I just have a couple old calipers I've had for years, but these look nice.

What are you up to there Danielson? Keep us posted on how it turns out.

Thanks Tim!

I'm sending some measurements, along with photos, to ATR services for possible sleeves for my recorders and a price quote. I'll keep this thread updated asap.

Good deal... I've been thinking about that subject for a while. I too would like to come up with a semi-permanent solution before I wear down the other side of my lifters.

Just remember... " Keepa Balance."

Cool. Do you have a TSR-8? I can't remember if the lifter poles are the same diameter as the other Tascams, but I know the assembly itself is incompatible...

Do you have a TSR-8?

No, but I think the TASCAM 388 lifters are the same thickness as the TSR-8 ?

No, but I think the TASCAM 388 lifters are the same thickness as the TSR-8 ?

Without calipers I can't measure them, but they seem to be just a shade narrower than the 30-series lifter poles. The 388 may be the same as the TSR, I don't know.
