Toolholders for tripan toolpost
« on: July 04, 2013, 09:08:43 PM »
Hello folks,

I just obtained a nice Tripan 111 toolpost with one toolholder on ebay, so i decided to make eight more toolholders.

For those not familiar with the Tripan, here is a picture of it:


I decided to use a prehardened toolsteel for those holders. I got enough material to make eight of them:


First on to the shaper, machine the outer contour:




The dovetail will also be machined on the shaper, but i roughed it out on the mill:


Back on the shaper, i finished the dovetail:



Measuring the with of the doveteil:


Nice fit:


After the dovetails where machined, each of the two profile pieces was cut into four individual toolholder blanks. Heading on to the milling machine, the slots for the toolbit where roughed out:


The slots where finished with a nice 6 flute carbide endmill:


The countersink for the height adjustment nut was also cut:


Two of the holders were designated to be boring tool holders, so they where drilled and reamed to accept 12mm tooling:



The height adjustment nuts where machined in two pieces, the nut itself from free cutting steel and the collar from drill rod (will be hardened later on):


The nuts blackened and the collars hardened:


Put together with a bit of Loctite 648:


I made the nuts from two pieces as I didnt want to knurl drill rod :D

The boring bar holders where split on the bandsaw:


Everything got a nice coat with a cold blue, some gun oil and a light touch off with scotch brite to give it a used look:



One original toolholder, eight copies :D


I am pretty happy how they came along :)

Now i need to turn the screws (with a square head) and make a suitable square-head-wrench for them...

So you should be! They look very professional.....   :thumbup:

I've never seen a Tripan toolpost before. Took me a minute to work out how it locates.  :scratch:

Well done Stefan!   :clap: :clap:

Hi Stefang

Great job - those holders look really tidy.

Just a quick question - you mention you used prehardened toolsteel to make the holders and it looked like it machined really well - did you use all carbide tooling?

Cheers

Paul

Hi there, Stephang,

That batch looks to be a very useful addition to your workshop.   :thumbup:   :thumbup:   :thumbup:  The shaper and mill are both enviable facilities.

I'm not familiar with the Tripan toolpost   :scratch:   :scratch:   :scratch:  How does the actuation get from the hexagonal spindle, past the large mounting hole, to the interchangeable tool-holder?
Best regards,

Pete W.

Very well done Stefang!  :thumbup: :thumbup: :thumbup:

By the way, that cold blue you used, what sort of chemical is that and what is its original purpose?

Cold blue is for blueing guns.. instead of heating and putting em into a oilbath you rub that chemical stuff on em. =)

I have a Tripan 111 tool post myself in need of extra tool holders. Downloaded their catalogue to see what they have. They are still in the market but a little expensive.
One interesting feature of these tool posts is that, the bigger ones can accommodate the lower size tool holder.

Thank you guys  :beer:

nice to see the shaper being used.

I like to run the shaper, cheapest way to remove steel, and pretty precise

Just a quick question - you mention you used prehardened toolsteel to make the holders and it looked like it machined really well - did you use all carbide tooling?

Its a steel for plastic mold application, its hardened and tempered to a hardness of 33HRC, it can be machined with highspeed tooling, but for milling i prefer carbide tooling. Its also very short chipping, but on the shaper and for drilling/tapping I used cutting Oil.

Quote
How does the actuation get from the hexagonal spindle, past the large mounting hole, to the interchangeable tool-holder?
Its a cam action, and the cam has a slot the size of the mounting hole and enought length to clear it when moving. But i will take it apart and take pictures, as its a but stiff, i think the grease in it hardened a bit.

Quote
By the way, that cold blue you used, what sort of chemical is that and what is its original purpose?

As neotech said, its to blue/blacken steel :)
I use that soup:

But I think they all are the same, based on selenium.

Even more expensive than the multifix toolholders. But the tripan holders are pretty easy to make in a homeshop..other than the multifix ones :D

PeterE,
This is the bluing I use.  It is a liquid or cream.  I apply it with a q-tip.  It works instantly.  You may go over old work and it will blend in well.  The cream is of a little lighter shade.  Then a light wipe of gun oil.  Do not know about the shipping.  If I can help contact me.  srmckuhen@att.net.

Stefang,
I followed your Bonelle T&CG build because of the shaper work.  I have since completed my own Bonelle using an Atlas  shaper and a Rhodes slotter.  I have tried carbide bits but always break them because of the interrupted cuts.
Several months ago there was a Rhodes 3 1/2 x 7 shaper and 3 slotter machine complete with vise, rotary table and all other fixtures and attachments on EBay.
I tried to bid just to have all the extras but it was soon out of my budget.  Some one bought it, I hope he is wise enough to keep it complete.
Thank you for the shaper pictures.  I can imagine the swoosh of the ram.

Nice work, well done.

I have do admit that I never finished the bonelle TCG, i sold it to a good friend who finished it. I got a real tool&cutter grinder that doubles as a small surface grinder for myself :)

You can use softer carbide grades on the shaper and also lathe inserts for interrupted cuts. But I get the best results with high speed steel...

A slotter would be a nice addition to the shop, but floor space is precious :D

Thanks everyone about tips on the cold blue.

Due to its originally intended use I think it is best to get it close to where I live.
