Diamomd tool holder

[ken heppenerParticipant @kenheppener64998]

Hi George….I placed my order on the 5th of this month and I’m still waiting for it to arrive…..Reading all the reports it still sounds as if it’s worth waiting for….Regards Ken.

Yes, the George Thomas article on the adjustable dials makes for good reading,but really you need to  supliment it with the graduating tool.

Hi Ken, The time that I had to wait was somewhere about the same,as I was away on holiday I am not sure how many days it took but it should be with you any day now and it should be worth the wait .  PS I got an email from Eccentric when they posted it

I placed my order on the 5th of this month and I’m still waiting for it to arrive..

 

Mine was ordered on the 5th August and I’ve had a message from my wife to say it has been delivered – total cost was £57.47 assuming there will be no further customs charges (are they charged for items imported from Australia to the UK?).

 

I ordered the smallest T6 size for my Taig lathe. Does anyone have an online UK source for the recommended M42 grade, 8% cobalt HSS square 1/8″ tool blanks?

Hi George and all readers….I got the tool holder a few days ago and I must admit it is a please to use…..I have never been all that great at sharpening tools free hand and now with this little tool jig that comes with it I am assured of a keen shart edge every time….It’s one of the best things that came into my workshop….Regards Ken.

Hi Ken,

Another convert to the cause!

I don’t know anybody who, having looked closely and has the wit to understood the concept, is not taken with the idea.

 

I now have a special holder just for threading, it allows the thread to be cut much closer to the chuck, see previous threads for problem.  I will post pictures as and when I think it can’t be improved, or see it at MEX at Sandown on the SMEE stand in December.

anyone got any drawings for making these?

 

[chris stephensParticipant @chrisstephens63393]

Hi Jim,

Do you mean Tangent holders in general or the threading version?

Hi There

I have an article about making a tangential turning tool.

I hope to include it in the next Model Engineers’ Workshop issue, No 156

regards David

Hi Ken, As I said before you would not be disapointed with the cutter,I found out to, that the sharping was very easy and a pleasure to do, as I myself was not an expert at  getting the sharping perfect most of the times, so in the meantime Happy Turning.

colin, I purchased a diamond tool from bay .com in america a few years ago & the customs stiffed me up for about £20 plus I had to collect it from p.o. sorting office & they charged me £4 for the privilege. I love the tool & tend to sharpen it more than normal tools as it’s so quick & easy making a better finish on the work,it’s not so good on brass as it’s got too much top rake.

[Colin ReedParticipant @colinreed51485]

Hi Graham

 

I also have been stung recently with import duties and fees when I bought a motorcycle tank from the States. I think I may be OK with the diamond tool holder I purchased from Eccentric Engineering as it had a declared value of 20 aud on the import slip. I’m sure there are no duties payable if the value is less than something like £15.

Hi Colin, hope you receive it o-k, mine was for the myford, which I have had for some time, what I didn’t mention was I ordered the larger one for the colchester a week before I went to australia & had it delivered to my relations over there & picked it up whilst there & brought it home myself. kind regards Graham.

[Jim KParticipant @jimk]

Hi Chris

I meant the tangential holder drawings, Dave might have solved it with his comment

 

[chris stephensParticipant @chrisstephens63393]

Hi Jim,

I await with interest the promised article on Tangential holders, I wonder what style David proposes to show?  There are also more than one style of tool sharpening jig, some easier than others!

hi all just to add my comments on the diamond tool holder. ordered one from gary in aus on the 24th and it arrived today . the concept seems great and first impressions after some straight forward turning and facing are that it is just that. . easy to sharpen and cuts really well . lots of playing still to do when time allows.  might i also add that  i enjoy this forum and model engineers workshop.

                                                regards andy

[andy mulhollandParticipant @andymulholland30577]

hi again . some questions and thoughts on the diamond tool holder.  if i wanted to grind the tool with a bit more clearence on the cutting angles what angle would you alter on the grinding jig supplied. would increasing the angle of the ramped slot have this effect.

  the other point i was wondering about concerns the limited approach to the chuck when threading because of the angle the holder has to be set at. if the threading tool was ground on  a round tool bit it could be rotated slightly in the holder. would this help or  am i missing something.  anyone any thoughts.

                                                   regards andy

[chris stephensParticipant @chrisstephens63393]

Hi Andy,

I have not had a close look at a “professionally” made tool holder, other than on You-tube so unfortunately I cannot say if they give you enough clearence but HSS is cheap enough to play around with and see what differences make

You are perfectly correct about the “near chuck experience” and if you come to Sandown MEX in December, have a look on the SMEE stand and all being well I shall have a few variations on the theme, including a dedicated screw cutting holder. I should be there to explain how you can make one, depending on what equipment you have.

chris stephens 

[andy mulhollandParticipant @andymulholland30577]

thanks Chris i will have an play with a few variants of grinding jigs when time allows. unfortunately i doubt  i’ll make sandown , circumstances are such that i’m pretty much confined to home, but i’ll keep an eye out on the forum and the promised article in mew  hope you get to where you want to be with your tangential tool holders and maby one day il get to see your work.

                                             regards andy

OK gents, I’m now sold on the idea. Placed my order with Gary this morning so we shall wait and see

I have made mine now, and I must say that it works very well. I have a little chester lathe ansd I can take a 2mm cut on steel bar without problems.

Because the forces are downwards, there is virtually no chatter, and the finish is good.

Only one error in the making of the sharpening jig, I made it the wrong way round!!!!

Oh well, nobody’s perfect.

Hi Keith,

I hate say I told you so, but…………..etc etc and welcome to the converted, your mission now is to spread the word.

 

Marvelous idea isn’t it, I really cannot see why it is not more well known, yes I can, in industry carbide  came along. Oh well, at least we hobbyists can still use them to good effect.

I made a holder the other day to take 6mm Sq. carbide tool, not too succesful I am afraid.

I think the tool needs to a be a good bit steeper to give the carbide more support.

Bought a Diamond tollholder in 1994 before I left Oz. I cuts like magic on my 918 type lathe. I later noticed a very similar device with screwed height adjustment in a Percival Marshall book of my Dad’s dating from the 1930’s. Used round HSS and showed how negative rake could be used on Brass etc. There is nothing new under the sun eh! I had never thought of using round HSS in the Diamond however so I will give it a try. Will make finishing cuts much easier.

Hi Andries, we had some bronze pully wheels to make for the rigging on my sons boat & the radius was just about right for  the 1/4” hss round, it did the job great without having to grind up a form tool specially for the job.

Dear Mr Editor Sir,

I have just looked at the number of views on various subjects and I note that this subject has the highest number, beating most by a factor of ten or so. I think, therefore, it is time you published your construction article and gave even more publicity to these “wonders of engineering”
