Thread: T Handle Allen Key Sets

Can you comment?

I suspect MC is talking about the type of T handle wrench that has only one business end, i.e. at the foot of the T. Presumably these do not always have the short arm of an ordinary allen wrench hiding somewhat redundantly inside the plastic handle.

Come to think of it, if I'm right, I'd be interested to know what they do have.

I think they must have had a metal shank inside a moulded plastic handle but they were returned to the company and I did not take any apart to investigate the construction.

The set currently offered have the "short end" poking out of the handle so presumably have an Allan key hidden inside the plastic.


Thank you both.

Clearly, there is more than one way to make these; the screwdriver type, which I favour for light work, obviously has the shank moulded into the handle and, of course, no short leg. I have one or two vintage Unbrako brand tees with forged handles and the shank located by a set screw in a hex recess in the forging; not pretty but they are strong.

For a cheap, simple tool however the standard Allen key takes some beating.

I had a set of T-handled Hex Wrenches from a local firm in Standon (which has now closed its Trade Counter and only supplies by Mail Order).

I found that one of the handles turned but NOT the hex shaft - so I took it back where it was refubded without argument.


I admit to being surprised by this unfortunate experience as my impression was that these "tee handled" tools are essentially ordinary Allen wrenches wrapped in a plastic tee-shaped handle so that the hex shaft is obliged to turn with the handle.

Can you comment?

A nostalgic note: years ago I had a conversation with the Verdict rep at a show as a result of which he sent me a couple of these FOC including the useful elephant's foot.

A good lens and white card background will help with failing eyesight or, like Dan Gelbart on YT, you can use a camera and monitor.

I like the Bondhus ball-ended drivers.

Vintage Unbrako seem good quality.

Thank you.

I gather from Wiki that the MAPP story is a bit complicated.

Is that gas mixture - see Screwfix website - hotter than the ordinary Calor propane?

Thread: Fitting a Drill Chuck Confusion
05/05/2021 21:10:40

I recently commissioned a keyless chuck with B16 taper hole in back, was struck by how far the thick end of the taper arbor projected from the chuck so went to the trouble of turning my own arbor.

The point is apparent from the OP's photo.

GHT's tests were on two of his own four way indexing tool posts and, for comparison, on the Myford ditto: four tenths for the "worse" GHT and twelve tenths for the Myford.

GHT's test job (in brass) involved both cross slide movements and tool swaps but, of course, the latter would not be prone to chip contamination. Details in his articles from ME or his Workshop Manual.

One of his reasons for favouring the four way was that he professed never to have met any QCTP user with more than four tool holders; I gather that there are some today with ten times that number!

This topic is outside my knowledge but I have a vintage leaflet from the Aerial Manufacturers Association entitled The Enthusiast's Guide to FM Radio Reception which I could send you.

It is going to be expensive getting a large number of QC tool holders.

I have some twenty tools lined up on a shelf above my Harrison 140, each sitting on their own packing piece, specifically milled for height for that tool (sorry, I realise you don't have a mill). OK, took me a day to do them all but now that's it, and very low cost. That four sided head is a delight to use and quicker to swap between four tools than QC holders. The indexing balls under my tool post work very well and if I rotate from one tool back to my DRO set facing cutter it is typically within a thou of the correct diameter - about the same as QC tool swaps.


A refreshing change to find a champion of the indexed four way toolpost as opposed to the pick-off QCTP!

At the end of GHT's description of his tool posts for the Myford he set out the results of a series of tests for repeatability showing a maximum deviation of about four tenths of a thou.

What about the coating, if any?

Thread: Boring 16mm hole in stainless bar

I don't know CT90 but it sounds good.

Plus one for Hopper's speed point - I actually wondered if you meant the reference to back gear.

Another point is that some suggest a pilot drill no bigger than the chisel point on the final size drill and no intermediate drills if the machine will stand it; this is said to be kinder to the flutes of the larger drill particularly if it is carbon as opposed to HSS (or cobalt).

If you are going to drill rather than bore the ideal would be a three flute core drill (a suitable boring bar would be cheaper and more versatile).

03/05/2021 22:46:57


I take it you are using a suitable cutting oil?

I would expect to be able to cut 316 with "ordinary" HSS and doubt that cobalt is essential.

Thread: Quick step mill
02/05/2021 11:08:17


Thank you for your helpful further comments. I admit I had failed to note that the instructions do say to invert the machine.

To quote from the promotional colour leaflet "In 1991 a version of the Quick Step Mill, designed for the larger lathe, won the top award in a design competition organised by the Worshipful Company of Turners. This machine created a demand for a smaller version suitable for the 3 1/2" centre lathe and for those lathes not equipped with a quick change toolpost."

There was some information about the QSM in MEW for October 1998.

If the gearbox is filled to the plug level with the machine upright there will be far too much oil in the gearbox.

This is a first-class bit of kit, with its own built-in vertical slide. My only objection is that its weight being well forward tends to bind the cross-slide dovetails.

Do you mean that the oil level should be checked with the spindle horizontal and the body upright?

The prize-winning forerunner to the QSM was, I believe, a larger and heavier machine.

01/05/2021 10:54:24

This point has been raised before here - do a top right of page search for quick step.

I *think* the filler plug is the hex screw above and to the right of the pulley from the gearbox. Please post when you find the answer!

Thread: Finding a penknife

Might the stainless knife nonetheless be magnetic and could it be fished out with a magnet on a string?

Victorinox used to do a knife like the one you describe ie not a "swami".
