When you said you couldn't get dog screws I said to myself "just make em!" Then the next sentence you said you did lol

Excellent video Paul ! i always wanted a boring head like that but had a gut feeling that buying a second hand unit may cause me some bother ! iirc Stefan Gotteswinter did a similar video possibly the same make and he didn't show how he got it re assembled again either so i think he had the same hassles you did ! i would also love a 3D taster but being a clumsy bugger i would probably drop it on its first use ! Man its good to see you back making videos !

What a really nice tool, lots she is able to do for you. We would like one day to have the Wohlhaupter UPA-2 as micro machinists that wold be our top size, so it is nice even though I understand the Japanese version it really is quit a tool to watch you share, thank you. A far cry different from the Criterion boring heads in America we grew up machining with. Lance & Patrick.

I see criterion boring heads up for sale for way more expensive than these super nice european/japanese automatic boring heads, after getting my wholhaupter upa3 I honestly cant understand why. Criterion feels like a toy compared to these.

Very nice addition for the shop Paul, my manual boring head dial is almost impossible to read... the engravings are very faint, cheers, Doug

I have the exact same model, buy it on ebay without any instructions. Thanks you to provide somes ;)

nice boring head Paul. FYI the top reversing pin holes line up with the interruption in the knurling of the lower graduated ring. Cheers

Thanks for that Phil.

Is the locking screw essential? If so do you think you could take a few pictures of it so that I can try to reporduce it? Excellent video!

Hello Paul, thank you for your nice video: today My Wohlhaupter UPA3 arrived, i have a question: the central locking ring have manu radial holes, why? And to use It? I have only to rotate the locking ring to stop the head after regulation or i have to adjust It? Thank you in Advance!! Alberto

That one is far different from my Wolhaupter. The ring on mine has about a dozen pins to engage the amount of feed depending on how many you push down. It also has a coarse adjustment using an allen key. I think mine is UPA-4?

We would love to acquire a UPA-2 for our little machining operation (costly) so you have a -4 wow nice to have, too big for us still nice for a knee mill we assume.

The UPA-4 and up have that feed system. I previously had a UPA-4, but despite what the seller told me,it had an integral INT40 shank, not a replaceable one and I sold it on.

Upa1,2 and 3 have single feedrate and automatic reverse. Upa 4 and larger have multiple feedrates but only manual reverse. Upa1/2/3 heads can be automaticly reversed without stopping the spindle pressing down the reverse button.

I have several Wohlhaupter heads but could never find out if the taper part is replaceable. You've dismounted this?

My Mizuguchi has a flange mounting. From what I was able to find out, the Wohlhaupters either have an integral shank, or one retained by a differential thread fastener.

Hi Guys, is a very interesting tool, the former boring heads were made whith the shank and the body of one piece, I don't know when Wohlhauter began to made de boring heads with interchangeable shanks, but I have a drawing from 1977 which explain how to change the shank. Actually the UPA 3 can use MT N°3 shank or ISO 30 shank, the UPA 4 can use either the MT N° 4 and ISO 40, the last one UPA 5 S6 can use MT N° 5, ISO 40 and ISO 50.

If any one needs the drawing explaining the mount and dismount the interchangeable shanks, just send the email and I will send the drawing.

Hi Paul, Stefan Gotteswinter has just had his taken apart to kzread.info/dash/bejne/f4SEsrGLnpmpZ8o.html , I got one almost the same mine is just a Lenz, incredible tight tolerances, very nice boring and facing heads.
