19mm adaptor bracket for XCS Plates

Nope, sent him numerous emails, never got a reply,.. which I thought unusual.

 

If Jerry Hill or anyone wants to make them or anyone else, I'd love to hear.

 

I still use my bracket weekly and it's been a life saver so many times.

Richard,

 

I know that these proved to be too expensive for you to make a run for sale, but did you ever hear back from Tom Gleason. I'd be very interested in a 15mm version for the kit. Thanks.

I could probably have my race shop build a few sets, I'd need a set of drawings

I'm speaking to someone about this now and hopefully we can go ahead and have a production run of these brackets made at a reasonable cost very shortly.

 

I'll keep this thread alive.

 

until very soon...

 

Rick.

 

 

I might have a solution, just give me a day or so to explore it.

The machine shop already had a surplus of Titanium going for a reasonable cost so it seems, and I had no good founded objection to the proposal, and for this application and at that thickness, it's more than adequate, and if anything only has advantages in terms of weight saved. The bars are still aluminium.

Good news -

 

The big green wire eroding machine is busy cutting the XCS adaptors out from 6mm titanium plate as we speak.

 

Should be done today, photos to follow.

 

 

Why would you use a spring metal when 7075 or even 6061 T6 AL is fine?

Well aluminium has a tendancy to wear away over time, it requires anodising, which scratches off, and its not as light as titanium.

 

My machine shop mostly make F1 parts, and we have loads of 6mm titanium sheet. It dosn't add much to the cost, and its much lighter and more durable.

I'm not going to agree with ANY of that.

 

Anodizing does not scratch off if done correctly, and if you hard coat the AL part you will have ZERO wear, not that it's going to wear in the first place.

 

If you look at the material specifics you'll find out that for our uses there is no need to use Ti in anything but springs.

 

Modulus Yield Point Specific Gravity

Aluminum 10-11 11-59 168.5

Steel 30 46-162 490

Titanium 15-16.5 40-120 280

 

Modulus is Stiffness

Yield point is in thousands of pounds per square inch

Specific Gravity is weight

 

Aluminum is 60% the weight of Ti and 34% the weight of steel

Ti is 57% the weight of steel

 

Even if you design the Ti part to have the same yield point of aluminum the part is still going to be heavier than AL.

 

Ti is used in F1 to gain the stiffness and strength offered by steel but at a lighter weight. It is also used for Flexure joints in suspension rather than rod ends and heim joints

 

Rather than trying to blow smoke as to why you're using Ti, just say that it's what you have laying around. For steadicam brackets there is ZERO reason to build them out of Ti. Al is perfectly fine

Well Im just saying that titanium is stiff and durable, lighter and in our case, abundant.

 

We use blocks of titanium the size of house bricks to hold the doors open, why not use it for something? All the F1 parts have to be made from logged and coded materials, so they usually end up ordering in new material for every job, which means loads of off cuts. Might as well do something with it, and if it means the end product is lighter than one made from aluminium, then so much the better.

You're missing the point, it's NOT lighter in our applications

Sorry Eric, have re-read your post and saw the bit about aluminium vs titanium for weight. Even if the titanium one is a little bit heavier, I still think its a nice thing to do, since we can. My guys at the machine shop who are 30 year experienced machinists recommended titanium for durability, and I have to listen to them. The cost is minimal, and they know what they are talking about. I have a very good relationship with them and they are not saying this so they can charge me more!

 

If you want your one made from aluminium, I am sure we can do you a special, if titanium isn't good enough for you!

 

 

Photos of the plates will come tomorrow.

While titanium alloys tend to be heavier than aluminum alloys the extra strength means that the parts can be made with less metal. If this is being taken into account then the resulting parts could be lighter while also being stronger, stiffer and more wear resistant.

 

A perfect example of this would be camping cookware. The titanium tends to weigh less than the aluminum because they make it so thin yet it is less prone to denting, etc...

 

Scuba tanks are another good example. Even without using titanium steel scuba tanks are able to be made lighter than aluminum ones because the wall thickness can be made significantly thinner.

 

All that being said I think titanium is a great material for a lot of what we do if used properly. The limiting factor is normally the material cost and the increased machining costs.
