    Yeah, thats my Wohlhaupter UPA3 universal boring and facing head (automatic).
    Since I bought it's proven indispensible - extremely versatile (a bit bulky at times for the size of the machine - but still brilliant).

    It was sweeping maybe 4 inches or so in Dia, probably had no more than a couple of hundred RPM on at the time, with a keen tool and a moderate feed - it was producing a terrificly fine finish, the trick is to keep it that way when all is done (Ally marks soo bloody easily when handling)


    It was missing a few bits out of the set when I purchased it out of ebay.de, but luckily there happened to be an item lot of Kuroda spares (enough to complete the set & more) that came up on italian ebay at the same time - I made the bloke an offer to end early.

    I think then for windage adjustment the shooter held off a judged amount into the wind?
    I've seen some American side mount designs of the same era, where they had a simple amount of correction in addition to this

    what power is the Dolomite, I'd be interested to see what you've come up with.

    I'm about to learn all about external adjustment etc, the next project on the drawing board is a Model 70 CRF w/ 8x Unertl & micrometer mounts.
    Here is a pic of the Dolomit 6 x 42/49. Please note I AM NOT RESPONSIBLE for butchering the mounting rails.... this low brow accomplishment was 'achieved' by its previous owner.



    The mounting I came up with had a plate with the usual dovetail bits on the bottom (Weaver) and a separate plate which had a pivot at the front end and lug which fitted into a radial slot on the lower plate. The top plate was to be swiveled by rotating a cap screw at the back of the contraption to move the top plate left and right, and then locked in position by tightening the cap screw in the front pivot and two more cap screws at the rear. The top plate would have dovetails to suit the Dolomit front and centre mountings.

    Unfortunately the computer that this file was on suffered a power surge, otherwise I could have easily supplied a jpeg for a more 'visual' explanation. I might have a back up on a memory stick...... somewhere.... ... but I could always draw it up again, if the missus and kids could leave me alone for an hour

    Are micrometer mountings available commercially? I did toy with a detent mechanism on the 'windage' screw... at the time I realised that a great deal of research (probably at the range) would be necessary to help calculate the division of the machined grooves if it were to have any similarity to the adjustment of the elevation turret... no doubt more research is required, and probably a lot of fine tuning once I get around to building the thing.

    Thanks Glen,
    Tubal Cain shows a boring head for fly cutting in his book "milling operations on the lathe" After your endorsement I'm going to buy one. It won't be as flash as yours though!

    Wow, I see Gunsmithing got it's own forum - lets not muff this up with politics!

    Your mount idea sounds good, I like it
    -probably have your front pivot a meaningfull 12mm spigot or bigger and have the fit to the top plate a really close slip fit and then the 2 rear capscrews sound good.
    -It depends if you want to take the odd really long shot without holding over? To ensure all the scopes internal elevation adjustment isnt used up just getting it to zero you could taper the lower plate of your mount (research on the specs of your scope and a lot of luck will determine by how much . I machined a 25moa taper into mine.

    Probably have a look on ebay for a cheap micrometer head and mount this, would be eminently more usefull & adaptable than playing around with existing micrometer mounts (you'll see why). The only new manufacture ones I know of these days are made by leatherwood and are reproductions of the Lyman/Unertl mounts - based around a 3/4" scope tube. I don't know if you are familiar with the system, but upon firing the scope was allowed to free travel forward under recoil forces until it came to rest against a stop and then was drawn back to "battery" by spring pressure (or by hand if the spring wasn't installed). a guide rib on the top of the tube and being supported/suspended (spring pressure forcing the tube against the 2 mike heads) in the the mount stopped it from rotating or losing POA under all this commotion. It is this setup I intend to use for my repro Model 70 build - but you would be able to see why it wouldn't be readily adaptable.

    If you can recover your drawings i'd like to see them.

    The auto feature is nice it allows you to cut int'l circlip gooves, do spot faces, counter bores with clean bottoms etc and if your feeling adventurous tapered/conical holes (but I've not bothered).
    But auto is certainly not essential and an ordinary boring/facing head still has much of the versatility and usually in a more compact package. Any thoughts as to what you may get?

    Glen,

    There is a small FZA boring head on German Ebay at the moment. Greg Q has one and thought that I could use one. Alas, the 20mm arbor stops me in my tracks.
    Might be a handy thing for when the UPA-3 gets in the way.

    Jack, cant comment too much on that as I've not used one - @ 12mm you might want to check, which dia shank boring bars you got that intend to use with it.
    The collect/adaptors give some options.

    Bob.
    yeah when you passed on it, good ol Greg forwarded the link on to me - I've sent the seller a message regarding postage. Ends tonight and it currently about that $100.
    I too will need to purchase a collet for it, as the R5 ones I have only go to 5/8". I'll need to chase the ones that do away with the adaptor and fit straight to the No# 4 taper

    I had been looking out for an FZA with the No4 taper and drawbar thread, but having a straight shack would open up a few options for use with the lathe I suppose.

    Don't get me started...

    May I say thanks to the Mods for creating a separate category.... I believe that Australians are somewhat more mature and laid back than Americans ..... there shouldn't be too many dramas. Non-shooters may learn something about machining techniques etc.

    Interesting idea with the micrometer... and very interesting commercial unit... something similar to scoped Winchesters you see in westerns... I think Clint Eastwood had one in 'Josey Wales'. I didn't think such things existed.

    I will have a look at the PC... I think I need to replace the hard drive and I should be able to recover the data by slaving the original.

    Got him!

    Did a little more over the weekend on the project, cut a further shoulder on the barrel and fitted the sandwiched recoil lug (very schmick fit) and thankfully maintained same head-space.
    Will be busy with site work related stuff for a week or so now - but after that, the next free day and it'l be on again

    I got talking to the ebay seller that I bought the FZA boring head off,
    has a few pretty nice machine tools in his workshop :

    He's also got a 13 manual, if your interested Bob?

    Very nice Glen,

    The other machine is a versatile Hommel UWG2. Here is a link to an old thread featuring a beautiful Hommel dividing head along with the usual sidetracking. I'll blame Gregory.

    If your interest is piqued there's more here. UWG-Hommel | Galerie » ASTOBA » Bild 8
    I'm sure there is a similar English site. I'll keep looking.

    BT

    PS. My mill came with an original manual.

    a "schaublin-style" lathe from habegger (from switzerland too) ( Habegger - Neotor Lathes ) neotor ,
    2 astoba uw1 universal "all in one" machines ( look at www.uw1.ch ),
    4 hommel uwgs (pic), 2 watchmakers lathes and a lorch lathe.

    I loved old machines.
    But the deckel is not really " old" , it is build in 1987.There is a big "wohlhaupter" bohring head (pic), so i never use the smaller " deckel FZA.That is th reason why i sold it.

    I've invited frank to join up and tell you all about it, so fingers crossed.

    Been talking a bit more with Frank (a real interesting bloke) and he has sent a few more pictures of his gear and his work.
    I figured some of you may be interested
