Ti-mo

I thought I should probably make a build thread rather than taking up space in the ‘what did you mod’ thread.

AFAIK mokuti = timascus so I have named this ti-mo = titanium (head and tail) + mokume (body). Inspiration from Tain Love

So I’ve had this mokume bar for a while now. I ordered 2 off 125mm*26mm (copper / nickel) mokume. The pieces I ordered must have been the last of the sellable bar because I received the end piece as well (free Party ). I used that end piece in this build. You can see in 1-2 of the pics the end which is all lumpy and jagged. On top of that the copper does not show on one side, so it looks plain silver. I didn’t get a before shot sorry, and now that I have machined it, it is difficult to make out that it is mokume at all. The copper needs to patina to really show nicely.

First thing I did was bore out the body, as close to the jagged end as I dared, and thread the end. I then made a pill and then started on the head. I did all the internal work before making and fitting a bezel.

With the bezel screwed on I mounted the head in the lathe and finished the outside. The engraver motor clashed with the jaws of the chuck so I could not run the grooves all the way to the back end of the head. I later had the same issue with the tail.

Once the body and head were fitted I cut the body to length and threaded the tail end. I wanted to thread it exactly the same as the other end. No particular reason other than test my skill. I wasn’t paying enough attention and failed Tired It’s close but not close enough to it fit both head and tail universally.

As with the head I did the internals of the tail first then moved to the outside finish. You can clearly see in this pic where I ran out of room for the engraver and grooves stop short of the work piece. I actually haven’t finished the grooves yet, so it’s still mounted in the lathe as I write this.

More to come…

I have no skills in this area and can not see or understand what is going on – but it looks fascinating!
Great light.

That looks beautiful pink. Sure wish I could do something like that.

Looking good mate.
Is it hard to transition from Aluminum to a harder metal like titanium? I guess stock removal will be slower?I

Nice work the design looks great Thumbs Up

What will you use to make the texture (layers?) of the mokume stand out?

About time this torch had its own thread. SmileBeer
I wasn’t game to ask why the steel was crappy on the end but you have now answered my un asked question.
Love the style and look. Personally I would not run the grooves to the end as i prefer the look of all the work being internal if that makes sense.
How did you go doing the cooling fins and what tool did you use?
Orsm job so far mate and looking forward to the completion.

I feel exactly that way when some of these guys talk about building drivers or writing code LOL

It’s not the first time I’ve cut ti. However this time I did need to replace some index bits and resharpen drill bits and HSS bits. I didn’t realize they were dull when cutting aluminium but ti is much less forgiving. When the bit is sharp and used correctly (height, angle etc…) then it cuts quite nicely. It is a must to use lots of lube. Aluminium cuts better with lube but ti needs the lube to keep it cool. I did like Dale and started a fire at one point. Didn’t ruin anything but I was definitely surprised when it happened. I do like using ti because it has helped me learn when I’ve got it right. Roughing out is slower but not by a lot (in my experience).

I don’t think I have the patience to wait for natural patina so I’ll look into forced patina. From memory some guys were using dishwashing liquid to bring it out??

My initial thought on the grooves was to mount the complete host in the lathe to groove the body and tail so they all lined up perfectly with the head grooves. I kinda forgot that when I was making the tail. At the time I made the tail I thought “I can cut the grooves now while the part is perfectly concentric”. I may be able to shave a little off the tube threads to try and line up the grooves, we’ll see.

I did the cooling fins with a 2.3mm HSS parting tool. Had to give it a quick touch on the grinder to keep it sharp but otherwise was no problem.

Cheers Beer

Your a better machinist than I. My HSS parting of tool has not been used for years as I never really had any success with it. To wide, not enough rigidity and not enough ability from me to get around the first two problems.
Nice effort.

A better machinist…? I find that hard to believe. Do you use a carbide parting tool?

Yep. Cheap 2mm carbide.
This one.

When I finished the grooves on the tail it still looked a bit over weight. I didn’t envision holes in the tail but that’s what I got. I am worried the tail (and head) might look too busy and detract from the mokume body.

Next is making a switch retaining ring. Then I’ll be at a bit of a cross roads. I think it looks pretty cool with a straight body as is. In which case I might have enough space to bore out the body some more to use 21700 cells. However my initial thoughts were to have a tapered, rippled or curvy body to pronounce the mokume grain.

… I’m still thinking my initial idea.

It doesn’t really show up in the pic but the grooves on the tail are not quite as deep (and wide) as on the head, I thought I had this suss’d Facepalm So many things let me know how much I still have to learn about machining Silly

I think it looks really wonderful as it is now Love , but considering the battery tube is made of mokume I can understand that it deserves emphasizing with a suitable texture Smile

Thanks djozz, I think I’ll go ahead with shaping the body somehow.

Switch retainer is done.

Beautiful work! I’m looking forward to seeing the body with some shaping.

Awesome work in TI. Some etching in the mokume will make my drool puddle bigger than it already is.

Yes, similar to that but not nearly as nice. The twist is… well… less twisty and as I mentioned in the OP one side doesn’t show any copper. Pic with one of the bars for reference.

My brother has a bead blaster. Shall I spray the ti ?

I was going to do this but am in 2 minds about it now.

I wasn’t happy with the switch retaining ring so I made that again today. It makes the switch that little bit harder to press.

Before

after

After that I assembled it with orings in place to check for water tightness in my water feature in the backyard. I’m not 100% on the bezel orings and might make some adjustment there but it otherwise survived the dunking without ingress. Of course, tried for a glamour shot…. but you know …. Facepalm

It’s a pity the layering can’t be seen all the way around. I really like the look of it Davie

Outstanding Pink! Not in the same league? Of course not, you’ve created a new one! Tremendous amount of detail work, jealous as all get out over here…

I have a short bar of Mokume Gane and a short bare of Timascus, haven’t decided exactly what to do with them. Won’t be anywhere near what you’ve achieved with this one I know…

I think me and Steve are going to drink some brewskies and beat ourselves up over how we fail… Beer

I wouldn’t abrasive blast the Ti.
I would complain to the seller bout the uniformity of the pattern. I know Mokume ain’t cheap. Might get a replacement for another build.

It still is a work of art. Love it…
