Winner Ultra-Small Boring Head

[donthack]

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.

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.

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

Thank you. If you could would you post a picture of you boring head. If it's what I think it is it is ultra precision.

Bill--I had a hard time taking good pictures of it and get all the nice detail in since it is finished so good and probably picked up the camera flash---anyway here are some for you to look at---Dave

 

[Bill Gruby]

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.
