3" Boring Head Modifcation

[@EverettsWorkshop]

That boring head is still a work of art, and I never get tired of you making new tools and parts for tools!

Thanks mate, I enjoyed making this boring head, possibly a boring and face head build in the near future to😉, thanks for watching, cheers

I just love your videos mate. It's so nice to watch a fella working and telling you what he's doing without banging on forever or playing crash bang music over it. Beautiful work on the mill and the mic.

[@MattysWorkshop]

Gday, I try to keep the videos simple and straightforward, I don’t change for the camera mate, what you see is what you get, thanks for watching, cheers

[@artisanmakes]

Great video, the mod turned out great. I think you could have also kept the old shank and used a Morse taper collet to hold the boring head. I do it on my mill and it saves so much space. Cheers

[@MattysWorkshop]

Gday, I did think of a Morse taper collet but I’d have to buy it, I had the material and the time and it was more fun this way, thanks for watching, cheers

Less stickout, less vibration, anytime you can go to the spindle directly, the better, great Job, looks beautiful.

[@jackdawg4579]

When you were building that, there I was thinking - look at that bloody Matty and his fancy schmancy Cincinnati - got Z height to burn, being able to mount that onto a spindle that fits into his ER40 collet system like that... :)

[@MattysWorkshop]

Gday, I completely overlooked this in a big way, I don’t have much z height at all, that’s the biggest letdown of the Cincinnati unfortunately, thanks for watching mate, cheers

[@ShedBuiltStuff]

That’s a thing of beauty. Taps? I’m just a back yard yob (so know nothing) but I bought quality spiral taps which are brilliant. They are classed as bottoming taps but I have no trouble starting a tap with them manually. And they power tap no problem.

[@MattysWorkshop]

Gday, As soon as I get some spare coin I'll be investing in some decent HSS taps, Thanks for watching, Cheers

[@wrstew1272]

[@nortiousmaximus940]

as always, nice job, nice video, that is one cool tool, l'd put something like that on the shelf in my home to look at. keep up the good work.

[@MattysWorkshop]

Gday, thanks for the kind words mate, appreciate you watching, cheers

[@samrodian919]

Great job Matty! Don't worry about forgetting or not seeing the need to drop the ER40 arbor. We all have senior moments mate, some of us me included more than others lol I think I would have made the taper fit closer to the spindle having got button headed stainless screws and probably could have saved as much as 10-12 mm in the available table height. Plus's the fact that the button heads look fairly pleasing lol But as you say mate it is what it is and will work fine. Just use some locktite on the screws as I don't see you taking the arbor off any time soon, that gives you some security against any chatter, although I'd get some steel washers instead of the copper as they will no doubt crush and the bolts will loosen unless you check and tighten them at every usage. Cheers Matty from the UK. Sam

[@MattysWorkshop]

Thanks for watching, cheers

[@graemewhite5029]

Can't beat plenty of fresh air between the head and the table ! I had to weld up then remachine a worn out bore on our timber trailer's H link last week on my little Tom Senior, had to turn the head through 90° and machine it horizontally. Home made line borer's on the cards, but it would be easier if the lads just exercised the grease gun now and again !

[@MattysWorkshop]

Gday, I’d like to have a go at making a line borer one day, I think it would be an interesting project, thanks for watching, cheers

[@bostedtap8399]

The "tin was a mission to get into", brilliant Matty, the Stuarts micrometer blue was the preferred choice during my time here in the UK, still using a tin from the 80's, its in a bag with some felt. Got a new tin somewhere 🤔. Great improvement, both on reducing height, and future proofing for other tapers, very nice job all-round. Ref the Hangefers coolant, doesn't take long to lose its translucency, not a complaint in anyway shape or form. Great video, thanks for sharing. Regards John

[@graemewhite5029]

We used to go through a lot of Micrometer Blue in our toolroom, mostly used for putting on the earpiece of the shop phone or the eyepieces of our binocular microscope !

[@bostedtap8399]

@@graemewhite5029 Brilliant, I had that done to me, ref a Loupe 😜. On another occasion I put it on a guys car door handle who pissed me off, it was everywhere, face, steering wheel.

[@MattysWorkshop]

Gday John, the micrometer blue works good once you get into the tin, the coolant has discoloured faster then normal and that’s my fault, I normally have a heap of rags on the foot of the mill to catch the way oil, I took them out and didn’t put any back, now I have to put the skimmer in and clean it up, im getting lazy mate, thanks for watching, cheers

Good job Matty. Z height is always at a premium. ER collets are fine but ive now a few R8 collets to gain that extra gap from tool to job.

[@MattysWorkshop]

[@malliz1]

Great solution mate looks good

[@MattysWorkshop]

Thanks very much, appreciate you watching, cheers

[@marley589]

Hi Matty, all worked out in the end. I suppose the Elephant in the room is why the morse taper was not bored or threaded and the boring head spindle machined to suit. Although concentricity is not important when driving an eccentric tool, plain or tapered registers could have located a threaded connection. It was a huge billet just to have a 3" flange connection driving a relatively light machining operation. You would probably get another 1/2" clearance too. It's nice to make your own tooling, personally I would have modified a new soft stock MT3 arbor that costs much less than the huge billet, or an old MT3 drill. Using the bolt hole feature was useful but exactly the same co-ordinates could have been used on the X and Y axes either NSEW @ 28.75 & 0 or +/- 20.33 on both axes.

Very good result. Hindsight is always 20/20. Too late now, but could you not have turned down the original spigot on the boring head to say 20mm (I cant remember how big it was originally) and have bought a MT3 20mm collet to fit directly into the mill spindle. As far as I can see it would have achieved the same result, except it wouldnt have made such a good video!

5.1mm tapping drill is fine, I use this when it's not a high strength application, ref electrical, or low strength applications, personally 5.0mm is too small, taps clog up very easily. 5.2mm is too big for engineering applications. I think ISO standards call for 85% engagement, SAE standards are a little lower if memory serves. That's my 2 pence worth.

Every metric tapping chart I have, including Machinery Handbook, for normal engagement thread, says drill size equals thread OD minus pitch.

[@williammurfin6354]

@@chrisbaker3844 Well, do you have a P&N chart. I have it 30 years. The one I've got reads as to drill 6mm you need to drill a 5.1 mm hole or a 13/64 hole to tap for 6mm . ( in mild steel) I have always been instructed by fitters I worked with decades ago with if your drilling holes into harder material try to go up .1mm or.2mm of a size to allow it to tap harder material as to allow for the crap to get out and for easier cleaning as you tap.
