Home made Torx T-9 insturment

Recently dropped a FRS walkie talkie, which now transmits but without any TX audio. I'm curious what's inside.

The Harbor Freight security bit set has T8 and T10. And as Goldilocks said about the porridge, one is too small and one is too large.

Torx sets are about $5 or less on Ebay, with the obligatory

2 week wait from Hong Kong.

With a small allen wrench, and some time on the bench grinder, I was able to make an oddly shaped tip, which was supposed to be smaller allen wrench tip. Didn't work out as well as I'd hoped. But, it did remove the necessary screws.

I also opened up a nonworking set I got off Ebay, which had corroded alkaline batteries. The contacts were beyond repair, or at least beyond my own abilities.

You bought the wrong set. They sell a set of six small 'star' bits that includes T-9. It's not always available, but I bought two sets the last time I saw them. I don't have the stock number handy, since all my tool notes were on that Seagate drive that died. So far, I've recovered about 32 GB of files between the failed hard drive and the corrupted backups. There is at least another 20 GB that I haven't been able to recover. :(

I bought a hand full of Torx bits at a flea market about 10 years ago that were mounted in uncut round ACE keys so you could carry them on a key ring, I still have a few T-7, T-8 and T-9 left. They had about 25 pounds, but they were too expensive to buy all of them.

Glad you got it open, but for future reference, Harbor Fright has three sets, an orange one, a yellow one, and a red one.

The orange one with the green-and-black handle, flex shaft, and magnifier is the only one with T9, as well as small metric allens and some others.

The yellow one with the orange and black handle and the tweezers has small SAE allens but no small metric. It also has some weirdies like the 5-pointer that you need to get some Sony stuff open.

Both the yellow and the orange are small sizes. The red set 100 piece set with no handle has the larger sizes--it overlaps the other two a little bit.

This explains why I've never felt the need for a set of small Torx, I bought the orange set when it first came out and at half off. Has met the need for opening up cases for several years now. Only problem is that the plastic case hinges gave out, it's got a rubber band latch now. I did have to order a T1 one time to get into an IBM Thinkpad. Nobody local carried anything that small, T5 was it.

O.K. A surface grinder and a small index head can work wonders on making small (or non-standard) Allen wrenches. SWMBO has a Tarus

5-shot .38 Special with the protective lock built into the hammer. It came with two "keys", which were 0.100" Security Allen wrenches with black plastic handles to go on your key ring. My ring I wear on my belt, and the plastic broke so my copy was lost, so I had to make a replacement -- with an aluminum handle so it will stay with me.

I guess that a metric country would think that an imperial size in a non-standard size would be secure enough -- but it is also a pain. There is now way that I'm going to order another from them and have the same failure. :-)

Hmm ... sounds like the set I got from MicroCenter (the computer box store), except that while the bottom half of the box is orange (the top is clear), the handle is orange and black instead.

It has four rows of bits, straight, Philips, torx (including T9, but not security T9 if you need that) and Allen (they call them hex) in metric sizes.

The flexible shaft looks like a lifesaver waiting for the right project, but it and the magnifier together are a pain, because the flex shaft is stored bent, and tries to pop out when you open the case, and the magnifier has to rest on top of it so the case can close, and tries to launch when the flex shaft pops straight. :-)

If I need a security torx in these sizes which is not in my current collection (I think that I've got them all covered in 1/4" shank ones of better quality anyway), I can always pop it in a hex collet in the lathe and drill the "security" clearance hole.

Enjoy, DoN.
