View Full Version : Enlarging the spindle hole in an LP?

I have a copy of Massive Attack's 100th Window where the spindle hole is really too small to even attempt to fit it.
What is a sensible way of enlarging it? I can pick up 7.3mm drill bits for a couple of quid, and an adjustable reamer for about a tenner.

Any thoughts/experience that people would like to share?

I've noticed this more and more. My box set of Bowie's 'Who can I be now?' needed every hole enlarged (ohhhh matron :eyebrows:). If it's just a tiny bit tight I use the outside of a BIC pen (the old style yellow ones) and gently ream the hole. but an adjustable reamer or correct size drill would do the job.

A tapered reamer should do it, coupled with restraint.
That, and making sure that the material you ream falls away from the record :)

I just use the tapered wooden handle of a paintbrush I have.

I am reminded of a user on another forum who put his Knosti in his cordless drill to spin the discs dry!! :eyebrows:

You could drill them out :D

Done this a few times, carefully, with a penknife blade, turned slowly and carefully, checked and if necessary turned again until hole fits spindle smoothly

I have just ordered a couple of 7.3 mm drill bits. I may take the .004" off then, but will measure them before I use them to make sure they are not too big.

I use a 7.3mm drill bit, but I have been known to use the pointed end of a potato peeler which works just as well. :D

Does the job extremely well.
I purchased a tapered reamer (7 to 9mm) off the Bay for just this purpose. It has only been used for this task, so is very sharp and has to be used gently, so as not to remove too much material. A couple of light back and forth rotations is usually enough.

Hi Ken, Do you have a link to the item you bought?

I bought it about 3 years ago, along with a ratchet "T" holder, so I don't have a link.

This is similar to what I have:

Using multi flute slow taper reamer keeps the hole round and centred and as you can see, cheap as chips.

EDIT: I've taken the link out, item was too large, you need a 1:50 taper reamer with diameter of around 6.5mm. I think a 7mm is the size, I will see if I can find one.

Its a 6.5mm 1:50 taper that is needed, which goes from 6.4mm dia to 8.78mm dia. Can't see that size for sale at the moment, a 6mm will do as it goes up to 8mm max. It will be 110/120mm long approx. They usually quote the max dia and nominal size at the small end which it will fit into.

Yep, that will work as well.

This 6mm one should be perfect: http://www.ebay.fr/itm/3mm-to-20mm-Straight-Flute-Taper-Pin-Reamer-Select-Size-/282116417510?var=&hash=item41af72e7e6:m:msp0SIsFUrmJd1iQDGr1FGw as it (apparently) goes up to 7.3mm.

It needs to be a bit bigger, my spindle measures 7.3 and you would be at the very top of the taper. The spindle needs a small amount if clearance or it will still be a very tight fit. Hence me suggesting 6.5mm but a 7mm will also work(narrow end dimension), you will be working at the narrow end of the taper with that. Mine is 7mm and the reamer only goes in about 15mm when the hole is the right size. To be honest some of the cheaper reamers with a faster taper would be good enough for the job, something like this:

Personally I would use a small rat tail file. I've got a few I've used for modeling and instrument work, but a round file from a mini file set works so easily, and is super cheap. Just stroke the file in curved stokes, working your way around, so that it's even as you go. I have also taken a thin pencil and wrapped stick on sand paper to it, that will also clean and enlarge a hole with a bit of control.

That looks like just the thing I need, cheers.
