Having fun and gaining more tools!
First class job, Jon. Nothing better than self-made tools. Thats our business. Regards.
Thanks
Thanks Jon
very good job jon..thanks for your time
Hi Tr, thanks for the comment and viewing my video. Cheers, Jon
great job great video John thank you for sharing
Nice to see the glue pot with brush at work. I 'm sure you like it very much.
Holder looks really good and ready to go.
I knew I recognised it... 😁 I thought there was only one oilcan with a beard. Now I know he has a brother in the UK. 😂
Hi Rusti, yup, your influence has spread to the lathe!! Very useful indeed, and yes, wouldn't be without it now. Cheers, Jon
That's a great addition for the lathe Jon. Nicely done.
Regards.
Steve.
Hi Steve, thanks for the comment and feedback, much appreciated mate. Cheers, Jon
Your boring bar holder came out quite nice Jon!
Hi Allen, thanks for the comment and feedback, much appreciated. Cheers, Jon
another great video mate, looking forward to the next.
Well done Jon. Stickers arrived - thank you. Sorry, I have been away and not keeping up with my favorite channels.
All The Best
Dan
No bother Dan, Cheers, Jon
Morning Jon. Beautifully design and executed. That’s a great micro boring bar holder. Thank you for sharing. 👏👏👍😀
Hi Andrew, thanks for the comment and feedback mate, much appreciated. Cheers, Jon
Great addition to the shop Jon, nice setups and machining 👌.
Ref BO1 material, the "O", letter O, refers to oil, for oil hardening.
Have a great Bank Holiday weekend.
Thanks for sharing
Hi John, thanks for the comment and hope you are well mate. Cheers, Jon
Gday Jon, the tool holder looks great and well planned out, having the option to change boring bar sizes quickly well be good, nice job mate, cheers
Hi Matty, thanks for the comment and feedback. Yep, a quick change in a quick change.... Who knew lol. Cheers, Jon
eyup Jon
Spot on, something to get your teeth in to on that job Jon, I know for a fact it took you 20 times longer than the 32:47mins.!!!!!
Turned out great.
Got your sticker, thanks very much, it came in the same mail bag as Olly's🤣🤣🤔🤔👍👍 i will stick it in to a future video, as i have 2 in the "can" ready to go, so will be in a couple of week, but thanks in advance, i know you have limited time, and appreciate you taking time out for me.
see you next time

Hi Kev, thanks for the comment and feedback. There is something else on its way to you as well, hopefully slightly more useful than a sticker😊. Let me know when it arrives just so I can stop cursing the PO. Cheers, Jon
Nice work Jon, always nice to have a large pile of tools on hand rather than making on an as needed basis. Enjoyed the video, cheers!
Hi Howder1951, thanks for the comment and feedback, it certainly is, you will soon see this being used on an upcoming project 👍. Cheers, Jon
Very nice work.
Great idea for the boring bar tool holder.
Nice video.
Thanks for sharing.
Take care, EM.
Hi Ed, thanks for the comment and feedback, much appreciated. Cheers, Jon
Nice work Jon. 🙂🙂
Handy little Tool.... some new on my "winter- season" projects!
Nice Video!
Keep it up!
Chris
Thanks Chris, well worth the effort, especially the small detailed work you do, it will be very useful. Cheers, Jon
Really like this idea Jon, will copy if you don't mind!
Cheers Neil
Hi Neil, thanks for the comment, and I don't mind at all, well worth the effort. Cheers, Jon
Good one Jon, Nicely done machining.... various size insert adapters keeps it flexible. Thanks for the eBay link I need to checkout those boring bars.
Cheers...ATB....Dean
No bother Dean, they work really well. Cheers, Jon
Good morning, Jon, nice crisp editing and lots of chips, it’s a winner in my book. 👍 The geometry of the Dickson form does seem complicated relative to other types, but you don’t seem intimidated by it. 😄
Hi Dudley, thanks for the comment and feedback. Lol, yes, it is a bit more involved geometry but never intimidated, the harder it is, the more fun you have! Cheers, Jon
Great stuff Jon. I think anyone using a medium/large lathe for smaller work could benefit from this idea. I've added it to my neverending todo list (you probably know the one.. 7 new items added, for every 1 item completed...). Mine's a sliding wedge style holder (aloris copy), with the boring bar tool block already made. I'd previously considered it a bit useless, because it's a very specific size. But making up a set of the adapter bars will be a great way to make use of it. Thanks for the idea.
Hi Craig, thanks for the comment. Yes, I have an upcoming project where I am going to be boring out to 6mm, so this is in preparation. Definitely needed on bigger lathes. Cheers, Jon
Only 7 to 1 ratio on the to do list....your in good shape 😂😂
@@TheAyrCaveShop 😂
Good job John. It takes ages to properly have all you want in a home workshop but It's getting there mate!
Hi Dermot, thanks for the comment. Yup, the list is never ending but that's half the fun I reckon. Cheers, Jon
Hi Jon, awesome video, I enjoyed it and learnt from it as usual! Very well presented!
Have to say tho Jon, you were missed last week, it didn't seem like a sunday morning without ya! 😉
Take care mate, regards Tony.
Hi Tony, thanks for the comment and feedback. Kind of nice to know I was missed, but may be absent from a few alternate Sundays going forward with other commitments etc. Will be doing my best to make up in quality what you lose in quantity though😇. Cheers, Jon
Hi Jon, no worries! I will look fwd to videos as and when they come along. Gotta sort out your commitments first and foremost! 👍
Take care and stay safe mate, regards Tony.
Great video Jon. I have the smaller Myford Dixon tool post I think a T1. I did make one tool holder just to see if I could. You made a better job of yours I think. Very well done. Cheers Nobby
Hi Nobby, thanks for the comment and feedback, much appreciated mate. Cheers, Jon
Hi John, you made the machining of the T2 holder look very easy, very impressive.
Thanks Tony, much appreciated. Cheers, Jon
Hi Jon, nice work! Did something similar on my smaller QCTH. I had a 20mm bar so made the block to take that, had the QCTH end water cut, made life easy! I then made up bar holders for 6 to 16mm bars, Joe Pie posted a video on the idea, freed up several tool holders for other things! Thinking I may be able to work it up to take a slotting tool as a bolt in/on addition….. Cheers Kerrin
Hi Kerrin, thanks for the comment and feedback. Yes, slotting tools would work well in this type of holder. Cheers, Jon
Excellent work. Just catching up as was down in London last weekend. Liked the way you tackled the dickson geometry.
Thanks Carl, it was certainly a lot easier than my last attempt 🤣🤣🤣
Good one . I need to make a heap of the same holders one day . Did you think of putting a dowel perpendicular through the bore of the holder . It locates the small boring tools with a bevel cut on the ends to automatically set the centre orientation . Great job . 👍
Hi Max, thanks for the comment. Thats not a bad shout, I may make the mod in future, thanks for that. Cheers, Jon
This video is timely I have just bought a 6mm carbide boring bar with carbide replaceable tips.
Thanks Mark
Very interesting Jon, when I made my T2 holders I set the angle of the head the same as you I was also reluctant as I had the vertical position spot on, I managed to pick up a T2 Dixon holder that takes an MT2 taper for drilling via the Carrage, not tried it yet, but have some more mild steel so think I’ll give your boring bar holder a go, would be interested to know where you purchased the micro boring bars from, nice one mr Jon
Hi Terry, thanks for the comment, this is a much easier method than my 1st attempt, just the tramming grief to deal with. I will put a link in the description in the next day or so to the Ebay reference. Cheers, Jon
Great machining again Jon. That will be a useful tool for those small diameters.
No problem moving the milling head as long as it is easy to tram in again. How long does that take to do?
Hi John, thanks for the comment and feedback. Tramming the head on these Chinese Mills is no fun, they are mega top heavy and unbalanced so every time you tighten the nuts, everything moves, it's a good 20 to 30 mins job which is why I generally avoid it if possible. Cheers, Jon
Ohhh! Sounds like there is a new workshop coming. Any information you would like to give us?
Hi Bill, thanks for the comment. Lol, no details yet, just pipe dreams. When I retire from full time work we will be relocating so a move is on the cards in the next few years (don't get too excited just yet lol). Cheers, Jon
@Jon's Workshop I'm a number of years in front of you. We are looking to downsize now. Finding somewhere with either a suitably sized workshop or with space for one is proving difficult. They do exist, but the house hasn't met with the much better half's approval. My other problem is that I have the luxury of 3 phase, I put in 30 years ago. We'll keep on looking.
Defiantly a plus having multi adapters, why to go Jon. I am sending out an email this morning to check the mailing address there, Bear.
Nice job Jon! One day I will be able to understand absolute and incremental, given the awful instructions you get with Chinese instruction manuals lol but probably not before I can no longer stand in front of a machine
Hi Sam, lol. Would it be helpful if I did a tips video on it? Cheers, Jon
@@jonsworkshop yes mate it would. In good old understandable English please!
Would you mind sharing some more details on those micro-boring bars? Brand, maybe where thye are for sale? They look like nice ones.
Hi Mats, thanks for the comment. I will add a link to the description in the next day or so, thanks for watching. Cheers, Jon
I hate moving the head. It's a bitch to re tram. I keep thinking about bolting a bar to the side of the column with another bolt pushing onto the head to help re tram for that micro adjustment. times like that you wish you had room for a bridgeport 😁
Hi Paul, thanks for the comment. Yeah, these Chinese jobs are very poorly designed, totally top heavy and unbalanced which makes tramming a pig. I reckon I could do 6 Bridgeports in the time it takes to do one of these! Cheers, Jon
@@jonsworkshop any ideas for making it easier?
G'Day Jon,, good result, i have seen others doing this but liked yours the best. do you have coolant on your lathe or mill??😀
Hi Graedon, thanks for the comment. No, not yet, will be adding some misters soon hopefully. Cheers, Jon
Hi Jon. Could you please tell me were you purchased the hand held oiler for the shaper.
Hi RB, thanks for the comment. Mine was a kind subscriber donation, but here is an Ebay item ID to one that looks very similar, if not identical: 273914427129 Cheers, Jon
Seems like a lot of movement of the table on the shaper....
Hi Nick, thanks for the comment. It's the whole machine moving on its wheels, I have still to site it properly on its feet and rewire etc. Definitely not the table based on parallelism checks I have done, although I must admit it does look like it on video. Cheers, Jon
What chemical black product do you use ? Very nice finished product !
Hi Tom, thanks for the comment and question. In two weeks time I will be releasing a video that goes into depth to answer this (I get asked it often). Saves me having to keep writing it all out etc. Cheers, Jon
Looking forward to seeing & learning from it
