Thread: Stainless steel hexagon bar in whitworth head sizes

I get my stainless hex from AMB since they are just down the road from me. All stock is listed in mm, but that doesn't mean to say it's all metric. wink

Well if you need something to knock the rust off one of these lathes, you could try this hammer

Dunno Sean, but on the strength of this thread, third from end posting, I bought one a couple of days ago, though not had chance to try it out yet.

Sorry- routine is left click on table, then right click and choose edit table, then set column width - try 30.

Neil, been having a play with that on the test thread, before I saw your answer.

I think the forum software bases the size display on the contents of the table.

I found specifying column width caused a problem, but specifying Table width seems to work OK

14cm seems to fit in the display box on the forum OK; well that's using Opera as the browser anyway.

 

Well that's weird. my first version of this reply wrapped my text to the right of your table, so I added 3 line feeds, only to find my text a mile below your table. I then deleted the 3 line feeds in "Edit Post", just like when I added them, only now it displays reasonably.

It would seem that What You See in preview, or Edit Post isn't what you get when you submit post or save changes.

Well that's even weirder, I haven't changed the text size.

Well that seemed to work as a pasted table from Word, using the "Paste from Word" radio button at the top.

Preserves the three different justifications as well, at least in the preview, shame the table is too wide on the submitted post.

Looks like you need to specify the table width rather than the column width

Thread: 2 odd items?
13/05/2017 18:40:20

I did wonder if it was an early safety lamp, possibly later sold as a heater.

The first ones ware all gauze rather than glass, as normally seen in the later miner's lamps.

Thanks for the offer Bill, but sadly I'm in Mid Wales !

However I do go motorcycle racing at Darley Moor Circuit occasionally...... well to watch the Classic 50cc racing club anyway !

If I'm up your way I'll give you a shout.

Please do, you'll be most welcome. Not be to that circuit for years, but looking forward to a re-visit with a camera sometime this summer.

A friend of mine used to race them years ago, apparently peak power @ 16,000rpm but engine expired @ 16.600rpm

Ebay No. 122485824478

Many thanks, now had I looked in my "Watched Items" list, rather than searching then whole of ebay, I might have re-found it before you posted.

Maybe need more coffee in the mornings

I find it intriguing because it has belt drive to both the headstock and tailstock.

I wondered that, but the headstock end pulley seems domed, as for a belt drive, but the tailstock end seems flat.

I did wonder if it was to allow a friction drive of the tailstock for a rubber wheel, perhaps driving, rather than driven??

Is the listing still up?

Nick, where in the country are you?

If it's within sensible travelling distance of Buxton Derbyshire, come and look at one in the flesh and drink coffee.

I saw it myself, but can't find the listing now.

I wondered if it was for grinding between centres?

Thread: Rivnuts?
13/05/2017 10:38:45

Certainly not a gimmick; I only have the tool you see in the photo, but it works fine up to 6mm.

If access is tight, you can make up a one off tool using a nut and allen bolt to compress the insert.

I just wish that the chap who built my Marlin kit car had discovered them, rather than using loose nuts and washers that need a major stripdown to get anything off.

All the best

Just spotted this on Gumtree for £250, which I guess is worth it even to break for parts.

Not seen it personally and have no connection with the seller.

Thread: Myford Super 7 accuracy problems.
10/05/2017 01:22:22

This may well open a can of worms, but have a look at Rollie's Dad's method of lathe alignment,

It's essentially the same method I used, before I was even aware of it, where, in my case, I employed a 2MT test bar and a dial gauge. Because you are only using a clock gauge, there are no cutting forces to consider.

In my case I couldn't afford a proper certified test bar, but found a brand new, beautifully machined and ground 2MT extension sleeve for £5 from a government surplus store.

I used that to set up the twist in the bed, though using the screw threads on the Myford raising block, rather than sheets of paper. Because it's 2MT, I didn't even need to use a chuck.

I then added a 2MT stub arbour to the 2MT extension, which allowed me to set it up between centres, and was thus able to set the tailstock offset correctly.

When I then used the "dogbone" testpiece mentioned above, with a very light cut, everything came out closer than I could measure with a micrometer, albeit not a 10,000" one.

"Levelling" the lathe is advantageous, but not vital. I've no personal experience of it, but from what I can gather, it's more important with large lathes in industry where the sheer size can allow the bed to distort under its own weight, if the cast in concrete floor mounts aren't perfectly level. I this case the precision level is used across the bed, at both ends in the same way that a wood worker would use "winding sticks" to check for a twist in the workpiece.

Sorry, too far from me in Buxton/Sheffield.

Are you sure you have all the windings the correct way round?

Lets call the old connections A,B,C, and their relevant star points As, Bs, & Cs.

I believe the delta connections should be;

As-B, Bs-C, Cs-A with the inverter supplying those connection points.

I've not yet done this myself, but have brought my motor up here to do the job.

09/05/2017 13:30:16

Jason, any idea why it's died?

It may end up being easier to get it mended, with it wired as star, and get a suitable inverter to drive it.

Whereabouts in the country are you?

Thread: Cycling Battery packs
07/05/2017 10:58:23

According to the links, the Imax B6 does up to 15 cells.

I have a 19.2v pack I'd like to improve a bit as new ones are a small fortune, so does anyone have any recommendations for a reconditioning charges for 16+ cells please. (Sealey CP3004 1/2" impact driver)

Failing that I may try one of these B6 chargers and dive into the battery pack and split it into two halves.

I appreciate I could re-cell it for about £45

Thanks

Bill

Thread: Removing Stud Extractor
06/05/2017 13:18:10

Posted by Andrew Tinsley on 06/05/2017 12:35:12:

Whenever I mix acetone with ATF fluid, they immediately separate into two layers. What brand name ATF are you using, so I can try it as a penetrating agent. It is highly spoken of, but I never had any success in mixing the two.

Andrew.

It does separate, but I just keep it in a small resealable bottle and shake vigorously before use.

Seems to work well enough compared to other commercial products, but obviously has the same limitations.

Here's an interesting link. referring to a comparative test, apparently from April 2007 "Machinist's Workshop" magazine comparison.

Have you given it a good soaking in a freeing agent and left it to rest for a while.

Plusgas is highly recommended, but I use a 50/50 mix of ATF and Acetone.

Obviously the acetone evaporates off quite quickly, but keep dribbling it into the thread over a day or three, whilst regularly tapping the end of the bolt/stud. Think about which way it was loaded before it sheared; tapping it "end on" might help loosen it. Similarly tightening slightly before trying to release it might assist too.

I'm with John on the things you screw into a hole in the stud; as he says, they're prone to expanding it, the if they get enough grip, when they finally break in the hole, you're left with a hardened plug to try and extract.

The Bolt Extractors on this page from Irwin are well thought of by the bike and Landrover fraternity, if you have enough of the bolt sticking out..

Also, you mention Adjustable Spanner, do you mean small stilsons, or are you using an adjustable on the end of a stud extractor?
