Thread: Parting-off Tools for Small Lathe
15/12/2020 10:39:27

If you do decide on a rear-mount toolpost, be mindful that the cutting forces will be pulling upwards on the flanges of the single T slot - you will need to spread the load as much as possible to prevent them tearing out.. ..especially if the tool is placed over to the side of the slide..

..might it be better to tap some mounting holes, or make a steel pallet to mount it on..?

Just to shake you out of your reminiscences, these are what they are trying to control

Amazon UK 2.25" Heavy Gauge Wire Darts .40 Caliber

'Outdoor Sports equipment, apparently.. ..I guess most of you were teenage engineers once, if you can imagine what the possibilities are for making these a serious weapon, you can bet that it's already been done..

I should say that until this thread came up. I had no prior knowledge that such things were considered a plaything...

"There's also a hole in the side which is meant to have a set screw and a small ball bearing. I think this is there to take up slack of the bore wears,"

Small ball bearings are not used to take up 'slack' in a bore, they would quickly indent any shaft and make it 'brinelled' - they are used generally, especially when backed up by a spring, as a detent mechanism but also maybe used as a locator in rare circumstances. Is there a corresponding drill 'pop', or two, in the shaft?

I think it's meant to have "setrscrew - ball bearing - setscrew" ..in the sense that the inner screw sets the adjustment, and the ball prevents it from being turned by the outer locking screw...

..another satisfied user of the JBTholder as per Rod & Jason.. ..they work well on the ML, and I do have to say that carbide insert tooling is what's in the toolpost for a rapidly increasing majority of general turning work that I do.. ..if you haven't yet tried CCGT inserts, I really would suggest buying a couple of those to trial in your existing holders as well..

Thread: Thread cutting problem

Might be worth checking that tightening the screw(s) isn't causing the die to cock in the holder, preventing it from sitting completely flat - I've come across dies with poorly formed or incorrectly positioned screw seats now & again..

..Thinking back a while there was a thread where the various changes in sources of the Vertex R/Ts was discussed at length so all those with good ones how long have you had them?..

Mine is a very recent one - the 'Test Report' gives the date July 28 2020 - had it long enough to have used it in both H and V for making small IC parts, flats/angles on tooling, and odd-jobbing where I've wanted to swap jobs still in-the-chuck from lathe-to-mill etc., but not long enough to have done any hard radial milling....

FWIW - the worm adjustment is sufficient to completely remove any backlash if required (though I prefer to back it off a bit) and the rotation is as acceptably smooth and even all the way round as one coud wish for in a cheap table. It doesn't feel as if there is any gross binding, burring, poor mating of worm & wheel, or foundry debris inside.

'Flatness', 'Parallelism' & 'Concentricity' all seem good - I had to dress-back one small bruise on the corner of the base when I first took it out of the box, since when it's been fine - by that I mean that I haven't noticed any errors/inconsistencies even making very small parts on a mill with DRO.. ..as a general rule, I rely on any faults revealing themselves to me through use, rather than go seeking them..

I wouldn't feel any apprehension in side- or slot-milling steel on it, within the normal expectations of "hobby" work..

I'd be genuinely interested to hear the circumstances under which other tables have failed.

I'd buy another..

For the record / in a nutshell.. the mechanism feels very good (for the money). The exterior finish isn't markedly better than other far-eastern equipment I have, but all the graduations are consistent, crisp and clear.. I'd guess that the money goes into the mechanism and grinding, and that the economies are made in the paint and fastenings / minor ancillaries.

I have a Soba dividing set for it - the quality of that acceptably good, the plates (thick CI) very crisply finished, with properly formed & chamfered, consistent & even holes. The brass sector arms are well-fitted and neatly made, likewise the plunger assembly and it's bracket. The fits with the mating parts of the Vertex table are comfortably snug & in perfect alignment.

I have a fair bit of Far-Eastern tooling from various (deliberately) UK suppliers - it's consistently of useable quality - there seems to be at least some healthy competition at any given price-point - I'd have thought a £250 Soba table to be more-or-less comparable to a £250 Vertex one? ..

..the pattern of both squares (the one in the box, and bigger one to left of the V blocks) - with bevelled edges and notch - is a "precision" pattern rather than "workshop" pattern - you should look at them carefully, unless you are sure they are just cheap c**p.. ..Do they have any marks/DIN stamps?

Thread: Bench Drill identification
21/11/2020 18:14:09

Is that hole threaded? ..it looks exactly what I'd expect if some former owner has used it to jack the chuck off it's taper before.. ..the 'witness' further in looks as if the end of a bolt has borne on the end of the taper within.

Pretty sure that the other Meddings "lightweight" offering, the Driltru, has a male Jacobs Taper on the end of the spindle. Certain that the smaller Pollards do.

I'd always thought that screwed chucks only really became widespread on pistol drills?

Might be worth slackening and "fiddling" the jaw plates, even if you have to remount it on the table and clock it in - it's worth taking a little trouble now to establish a known "good" datum for the future, surely? ..not sure what kind of wiggle room there is, if you slacken them off, you'll be able to see if it looks possible, or is a complete non-starter, before committing, I guess..

...I will use either M1.0 or 14 BA cheesehead to secure the cam shaft. I want to find a good quality supply of steel screws first(non-stainless, I'll be blueing them). When I find them, I'll buy the appropriate taps. If anyone has any advice on this, I would be grateful...

Steve

EKP SUPPLIES and BA-BOLTS are two suppliers that list plain steel cheesehead down to 14BA.. ..others might too, those just sprang to mind..

I have and do use EKP, satisfactory fit & finish on the larger BA stuff I've had - I've seen BA-B recommended before, so probably fine as well.. ..there may be others..

Thread: Warco WM18
03/11/2020 10:38:17

By way of a "bump", this thread has a few pictures that might be useful for a quick visual comparison;

WM18 Power Feed

..or perhaps some "leads" for correspondence..

If it's any further help, I see the Warco unit suits a number of different models which are all listed under the same part number, so I'm guessing that there's some rationalisation of feedscrew sizes etc. across the range - are the handle (shaft) ends on your '30 17mm? - certainly the Warco Major's (listed as a suitable recipient for the kit) are.

If one can establish that the wormwheel will fit the shaft, that would be one of the more potentially-troublesome variables out of the way..

The feedscrew brackets/bearing housings look rather more variable - Whether fitting for all models is a simple like-for-like replacement of parts seems to be a moot point perhaps..?
