I'm looking for some 5/8"-3/4" x 1/4" (or thereabouts) thick Ti. I only need a couple of inches of the bar. Anyone have a cheap source for me. TIA :bow:

Oh, that is gonna be fun to machine...

McMaster has it:

But it ain't gonna be cheap, and you have to buy a foot of it...

McMaster is kinda pricey. Some Ti doesn't machine all that bad. Drilling it can be problematic though.

Yep, drilling titanium is a nightmare, and welding it even more so. Moreover, titanium alloy is very expensive, like iron and aluminum it must be alloyed with other elements for most applications it is used for.

Dave, titanium joe looks like a good resource. I also found a place that sells Ti for knifemaking.

I have bought aluminum bar stock from them with good results and at a great price.

Regarding the difficulty of machining Ti, as I recall, Mark is a machinist by trade so he knows the score.

After 24 years , perhaps he should give up and get a powerful laser cutter/driller. I suppose that they exist.

I made some roller furling devices for a sailboat . Ti requires slow speeds (24 years?), a rigid setup , sharp tools , coolant. It work hardens . My father got some beautiful tube surplus , about one inch bore. He used some of it as towel racks on the sailboat he built . It is now hauling tourists in Puerto Vallarta, Mexico. Google "Ingrid ketch Victress".

Another source for Ti I would recommend it Shapiro Supply in St. Louis, MO. I was just there today to pick up some great aluminum tubing for a scope project.

Mark,

Can I ask what you are using the Ti for?

Greg, the Ti is for boat parts on my r/c sailboat. It has an aluminum mast step that is getting a fair amount of corrosion on it, and the support for the spreaders is SS, so I'd like to make it out of Ti and save some weight.

My current project is to make a couple of punch sets out of A2. The punches will be used to cut "hatch patches" for my International One Meter boat. The patch material is an adhesive backed fabric, and the punches will be used with an arbor press to cut the patches out like you would use a cookie cutter.

The punches worked. The circular one worked the best, and the other punch needed some help. I think the tools were getting dull and I ended up with too much of a flat on the second punch, so I re-ran the 20 degree cutter a little deeper. I need to get some more sailcloth material to see if the modification helped the situation. I was using a 2 ton arbor press to do the punching. We have a 30 ton hydraulic press at work as well, but I'd rather cut the material than crush it.

Ron, I thought about that, but I'm concerned that the heat would damage the adhesive backing. That and the fact that I don't have much room for storing the contraption.
