I am not a machinist but in fact a welder and a pipe fitter. Having said that, I can honestly say that this is quite possibly the best piece of hand machining I have ever seen. Incisive in design and flawless in fabrication. You Sir are a true Craftsman in every sense of the word. Kudos to you.

Translation: 0.01 - 0.04: External conical turning (tapers) 0.05 - 0.07: Conical holes (tapers) 0.08 - 0.11: Cylindrical holes and flat facing 0.13 - 0.18: Internal radii - External radii 0.33 - 0.36: Boring and facing head - Tapered, cylindrical and spherical 0.41 - 1.04: After this brief introduction, we'll begin mounting the head. I hope to show clearly how it's made and how it works. This is not my idea: I just copied an American head from the 50's, though its dimensions and design concept have been somewhat modified. As far as radius cutting is concerned, let's just call it an experiment. 1.05 - 1.24: Let's start from the main body. First, we'll insert the shaft that carries motion from the upper to the lower part. In the upper part we have a 16-tooth gear, whereas on the opposite end we have a worm screw. The shaft is mounted by pushing it into a brass bushing with a bit of grease. 1.35 - 2.11: Next we block the whole thing axially. Now we insert the 47-tooth idle wheel that engages the gear I've just mounted. Now we'll mount the upper 46-tooth gear wheel. This wheel is kind of special: its tooth profile has been modified so that the external diameter and the interaxial distance with respect to the sleeve's gear, as we'll see later, are the same as those of the wheel below it, which has an additional tooth. We use a locating pin to prevent rotation. 2.15 - 2.51: This 16-tooth spur gear placed inside the sleeve will orbit around and simultaneously engage both central wheels. Motion is transmitted to a gear which has nothing to do with the boring head itself: it's just there to show more clearly the movement of the central wheels (after I close the sleeve, you won't be able to see anything). I reality, the roles are inverted: the gear rotates and the sleeve remains stationary. Under this conditions, it would be quite hard to show a simulation. 2.52 - 3.00: Let's have a look at a 3D animation that shows the lower part with the worm screw and the rack. 3.05 - 4.10: Let's mount a shaft to the upper part and fasten it with a screw. Now let's mount the wheel that will engage the worm. The wheel is not fixed to the shaft: it trasmits torque through friction only, thanks to the clamping nut at the back. This arrangement has two advantages: first, it allows for a kind of variable friction clutch; second, it allows us to manually rotate the output pinion independently of the gear transmission. In fact, the pinion has an hexagonal profile so that it can easily be rotated with a spanner. Let's have a look now at the first accessory that allows us to do tapers and countersinks. The main piece has a rack at th back that engages the pinion at the centre. The flange allows the following cam to rotate around the centre. 4.25 - 4.38: Now we can fasten it at any desired angle. The gear ratio has been calculated to push the slide 0.04mm per turn. 4.42 - 4.46: Let's do some manual adjustments. 5.18 - 5.34: Now let's look at the radius-cutting attachment. The flange is the same for both adaptors, and they can easily be replaced just by loosening two nuts. Motion is always transmitted by the pinion to the wheels, that will rotate in the same direction. The wheels have been cut so that when the locating pins are inserted, the slots are perfectly aligned. This is necessary in order to control the excentricity. We insert a wedge pin in each disc. As you can see, the discs are different: the disc on the left can be regulated with a screw, whereas the disc on the right is idle, so it can adapt to the rotation of the other disc. Now we mount the tool carrier... 7.11 - 7.13 : Now we mount the two backlash-adjusting shims... and finally the tool holder. 8.19: Let's do some manual adjustments. 9.01: Excentricity: 20mm 9.39: Excentricity: 5mm 10:15: Let's do some boring on aluminium pieces. We have an internal taper, an internal radius and an external taper. The internal radius will be cut in several passes. I'll use another boring head to take most of the material off, taking care to stay within the desired profile. Then I'll do a couple of finishing passes. You can see on the drawing the depth of each pass. 12.45: Excentricity: 8mm 16.11: Since I don't have a right-hand boring bar, I'll use a left-hand one and "pull-bore" the piece.

Fantastic. I've looked at the Tree boring head for some time as there are some operations in which I can't use the lathe to turn tapered bores. I think I'll have a go at designing one but around half the overall size than this. All the best from the UK.

Exactly what I was thinking, can't afford the $1000 for the 'real facing/boring one, especially when it may only be used every 2 years or so. It's a fascinating machine in it's own right though. Maybe its a watch/clockmakers invention?

Da meccanico a meccanico, eccellente lavoro, credimi. Anche se gran parte del congegno non è idea tua vale lo stesso discorso. Avendo a disposizione una fresa più grossa, con almeno un cono ISO30 potresti rendere più rigido l'assieme e ottenere anche una finitura di tutto rispetto. Meriteresti almeno 10 volte le visualizzazioni che hai avuto!

A sledge hammer to crack a wallnut......sigh, does no one have any simpler ideas for a facing head? Many years ago there was a design and castings available in the Model Engineer........a UK magazine for model makers......... to make a boring head, but more so, with a star wheel on the incremental screw you had a simple facing head. I suppose one of those cheap EBAY boring heads could, with a bit of cunning design, be persuaded to become a facing head too. The problem with the EBAY boring head is that the screw moves out with the slide which is not what you want to happen for a redesign to become a facing head. Now, there is a boring head around that was/is made for the Bridgeport mill, probably by them, and that one could be modified to do facing with a star wheel on the advance screw.......I have one and might have a look to see if it's doable.
