The three ring logo is for "Ballentine Ale". Some will and some won't recognize the logo because "Ballentine" closed it's Brewery in 1972.

"Billy G" :whistle:
Ya' spelled it wrong!

It's "Ballantine".

Actually I know I spelled it wrong. I did it on purpose so people who did not like the Boring Head would still have something to say without bashing the project.

Steve;

The boring head has quite a few jobs under its belt now. It performs flawlessly every time. I use it more that its big brothers. I am toying with the idea of making an even smaller one.

Thank You for taking some of the mystery out of the boring head. With your excellent step by step instructions, I almost feel like I could make one. It is near the top of the list for a winter project. If it was meant for light duty, would aluminum work, or is brass a minimum requirement for strength?

Cheers,

Tom

I used brass because I grabbed it first. :lmao: I have easily made .040 cuts with it. Use whatever you have. The prints are in post #16 in PDF.

Be careful if you use aluminum, especially 6061 as it tends to gall when you slide it together. You could try anodizing it, or using some anti seize compound, both will help. You could also make either side of the dovetail from steel or brass, and you will get less "sticking".

I made a small boring head (not as small as Bill's, mine was 2" od) early on modeled after this one {url}http://homepage3.nifty.com/amigos/boring_head/boring_head-e.htm{/url}. I also used 10L14, and it worked just fine and is easy to machine.

Would 1018 be suitable? I have ready access to hot or cold rolled stuff, but nothing much else. At least, not that I'm willing to shell out money for till I am sure I can do the work. :)

Thank You so much for the wonderful build! This forum has given me the drive to make chips. Sometimes making me even want to fix my mistakes.

Bill--very nice job and It's rewarding when you get a lot of compliments and the finished product works so good----I know it is small, but when I bought my lathe back in the late 80s along with all the extra tooling was a very small boring head. after seeing pictures of yours completed--I went to my extras drawer and dug the little boring head out---I'm not sure if the lathe owner made the little boring head or someone else, but it is sure a precision job---no markings on it at all and it has a 1/2" shaft--I'm not sure if is a short taper on the shaft or if it is threaded on the end----I have not taken it off the sleave which is 2" long 1" OD and 3/4" ID and 1/2" id where shaft enters. the end of the boring bar shaft is approx 1/4" when I see it 1 1/8" in the end, which tells me that it may be turned down to 1/4" and threaded---Anyway knowing that you are thinking of making a smaller boring bar made me think about this one----the boring head is 1" long by 7/8" od and the sides are 5/8" wide--it has two 1/4" holes for the boring bars and is on a dovetail slide---if I had made one this perfect out of steel I sure would have at least put my inits on it---be sure and sign yours, and thanks again for the nice thread----Dave

Those are just fine. That is non other that a Moore Ultra or a perfect clone. That is only the second one I have ever seen. The other one is here in Ct. I will see if I can get more info for you. That is definitely a keeper.

Bill--wouldn't it have some markings on it if was a Moore Ultra ? I have an older (82) machinist friend that says it was probably homemade by a perfectionist ---Dave

Look in the empty hole on the bottom. If there is an "M" in it, it is real. The outside hole will have a "U" in it. Now if there are no stamps then it is the most perfect reproduction of anything I have ever seen. Nice tool either way.

Bill--all I see on the inside of the large hole is the 1/4" end with center from the boring head shaft.--do you know if they would have turned the BH shaft down on end and threaded it ---the only thing else I could think of would be a taper on the BH shaft from 1/2" to 1/4".--there are no set screws in the front of the sleeve to hold the BH shaft in, but there are two set screws in the back 3/4" ID section of the sleeve to mount on 3/4" shaft.--Does the Moore Ultra have a threaded 7/8" long shaft on it ?--do you know if the Moore Ultra had a sleeved shaft come with it at all ?--also do you know when they made them ? --I got this one used in approx 1988 or 1989--I hate to try and unsrew the shaft from the 1"ID 2" long sleeve untill I'm sure that it is threaded on------somehow though I don't think it would be on a taper without a tang that was round. --Dave

The Moore is a taper fit on the shaft. Yours does appear to be a straight shaft. If you don't have to take it apart, leave it intact. It looks to be threaded on. It's a tough call.

Bill---well curiousity got the best of me and I was sure it was a threaded shaft--so I carefully put a little twist on the 1" sleeve while holding the boring head in a crescent wrench not to scratch it--well it came unscrewed just like it should--and it does have a short tapered shaft with threads on the end like I guessed----real professionally done----well then I figured I might as well disaaablade pics 034.jpgaaablade pics 002.jpgaaablade pics 006.jpgaaablade pics 010.jpgaaablade pics 011.jpgaaablade pics 030.jpgaaablade pics 031.jpgaaablade pics 032.jpgaaablade pics 033.jpgmantle the little boring head and take some pictures for you---it was very difficult to get real good pictures but I'll send you nine to look at----sure is a cute little bugger----somehow I think you will be making one like this someday----you definately have the skills and tools and patience----------------------------Dave------------------------:))

That is one beautiful piece of work. That taper is for a small Jig Bore. Amazing.

:lmao: For the most part I am in the shop 80% of the time. The other 20% is spent thinking about being in the shop. It was only on this project that time was limited. :lmao:
