Thread: What Material for a rear tool post
19/10/2018 00:07:24

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.

Thread: Removing and re-chucking a part whilst thread cutting on Myford Super 7

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?

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

Thread: Tool i/d and Mitutoyo vernier advice please.

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.

25/08/2018 15:09:06

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

Thread: Resetting zero on Mitutoyo dial caliper
25/08/2018 14:41:28

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.

Thread: Tool i/d and Mitutoyo vernier advice please.
24/08/2018 17:20:37

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.

24/08/2018 13:32:09

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.

Thread: What did you do Today 2018
21/08/2018 17:05:13

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!

Thread: Metric threads on an ML7
21/08/2018 16:23:43

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.

Thread: LED Strplights
20/07/2018 21:08:01

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.

Thread: Boring Head
17/05/2018 12:48:38

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

Thread: Metal spinning without the need for skill, well almost without the need
08/05/2018 13:23:21

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"

Edited By JasonB on 08/05/2018 13:28:11

Bazyle, Doesn't everybody have a need for small dishes?smiley As the description under the video says these are repair parts and when finished they will not look like dishes at all, hopefully.

You are of course quite correct about titling, but a bit late now as it might confuse people. Following either link would give everybody easy access to my channel where they can find part 2 and other things that might prove interesting with more to come, as and when. The channel name is the same as my name, which seems simple enough.

08/05/2018 12:59:40

Ian SC, That was my thought too, and I think I was right.

08/05/2018 12:57:09

JasonB. You clearly have the knack but you and I know mild steel is pi** easy to spin. You may have noticed in the second part that I was making more than a one.off and also that the spun part is not actually in contact with the mandrel, something you do more easily with a roller in the toolpost.

Samsaranda, Proper spinning is a black art, till you give it a try that is, this technique is more than fit for purpose for the task in hand and as the video title implies anyone can have a go. A caveat would be I was spinning mild steel which does not need annealing, unlike brass or copper, and in real spinning the art is knowing when to anneal before it's too late and things go pear shaped.

Don't be fooled by the noise, that is a function of closeness of the camera and the microphone. I have heard a Warco and I can assure you a Bantam is very much quieter than the particular Warco I am thinking of.

Emgee, indeed the power feed increases the noise level but even when running it is not oppressive, especially if you use thick chain saw oil on the gears.

Jim Nic,You are welcome, I thought if the mysteries were dispelled more folks could have a go. The blanks are bog standard mild steel sheet about 0.8mm thick. Had it been a copper or copper based alloy it would probably have needed to be annealed several times during the process.

SB5, Although I put a hole in the discs they are for the second part of the operations, I will put up a video of that later when I get back to making the parts. As you can see from the video once even the slightest bend is formed it holds the disc in place adequately. Give it a go, but try MS rather that copper or brass till you get the hang of it. The advantage of a roller in the toolpost is you don't have to go down to the mandrel, you use the cross feed for OD sizing, which means you are unlikely to over stretch the metal which is a problem when learning the proper way of doing it. Oh and thanks for the compliment, much appreciated.

08/05/2018 00:39:49

Thanks for your concern, that's why I mentioned in the video about the paper. If it should get caught,very very low risk in the situation,no harm would be done. The cloth was only about 9 inches square and again should it have been caught in the jaws no possible harm would occur.
