Hi all, my fear is that there will be no more exhibitions. A show relies on two things, punters and trade stands. If punters are scared off by close contact, no shows. Traders by now are either out of business or have come to rely on the 'net for business and will no longer accept the inconvenience and costs of attending events, again no shows. I understand organisers are understandably risk averse but someone has to show faith or lose the lot, but perhaps the end has been on the cards since so many traders already abandoned us, and this china flu may be the final nail in the coffin. I do hope i am wrong as we have lost so many already.

For a really fine cut finish there is little to beat a shear tool and counter intuitively cutting in reverse direction. Cuts in the tenths of thou range are entirely feasible, and obviously that means they cut cleanly which helps the finish even on awkward metals.

For a really good appearance, roller burnishing is hard to beat and there are several videos on the net to demonstrate the process, i in fact have one myself showing a very simple set up.

Dial calipers have a nasty habit of jumping if dropped, the fix for Mitutoyo is simple and by coincidence I have a video of it on my youtube channel. Just ignore the badgers, it's in there somewhere. 😴

Do i understand correctly that you drilled a hole through the stuck sleeve, if so put a bar through the hole and beat soundly on a drift down the quill. I'm probably getting it wrong so dont shoot the messenger.

To make my rear tool post for my Bantam I used a top slide and part of the cross slide from , I think, a Boxford. It's useful because it still has its indexable four way tool post.

You will please notice it makes no mention of where the inserts are made, only tools, bars, blades etc.

For fine adjustment of threads you might find a hand held thread chaser of some benefit. No need for realigning part with a leadscrew or even running super true in the chuck.As another benefit you can also get correct thread form on rounded Whitworth threads. Do Tracy Tools still do their chaser sets?

Do

Gordon, Not a chance, you just loose two pieces.

indeed, and if there are any muggs, sorry, potential purchasers out there I will sell them one for half that.( UK only & TandCs apply)😂

Thank you Michael we try. As long as one chap(ess) can learn from it, it was worth showing the world my grubby fingers.

Clearly the seller has a great sense of humour! Mine is a short length of 0.9mm stainless wire not too carefully bent to a square at one end.

As promised a video has been posted on youtube, the link is in a separate thread to allow easier searching for future readers, but just in case the link is here too

As promised on another thread here is the video, I have put the link here as a new thread in case the other thread is not followed by all.

I have come across calipers marked Mitutoyo that do not have the feature, whether they are cheap knock-offs or older versions I cannot say.

Holy crap, $20 with postage! This is another of those cases where if you have a need for one, caliper user and a clumsy bugger who keeps dropping things, guilty as charged, then you should be able to make your own for less than pennies.

I will video its use and post a link soon-ish, biggest delay will be damn slow whiffy connection.

Sorry to contradict you Micheal but to zero the dial you use the special tool (that bit of wire with a square bent at one end) that came with the caliper. Turning the dial is just for very minor alignment. I was only thinking about putting up a video on how to do it earlier this week as so many folks seem to not know how it is done.

What did I do today? Well by my estimation I took a couple years of my life by boring and sleeving the oil pump housing on a BMW boxer crankcase. Close tolerance work leads to nerve racking and palpitations, hence life shortening, it pays well but is really worth it?

I can see why some folk take to drink, even though I have done it before and should have learned by now, guess that makes me an old dog.Ho hum!

Cannot give complete answer, but could they be 0BA rather than M6 both being 6x1mm?

edit, not very quick on the keyboard today, or, great minds think alike, your choice.

Got a couple for my shop and, once I read the blurb, found you don't need the standard fitting and only need to supply mains to one end for them to work.So, 6 spring Terry clips, 3 more tubes, some chocolate block and a bit of wire and I now need sunglasses to operate my mill.

Second for tramming your head, the boring head is probably longer than the drill so will be more to one side.

I have loaded a few pictures, in a video, of the kit in pieces to make it easy to see the way it was made. Please excuse the dreadful music, blame microsoft. the out of focus part I take full credit for..

for Bazyle, or anyone with a computer that blocks links, the title is "metal spinning roller in pieces"
