Tim,
Any updates on production status?
Any updates on production status?
ttriolo said:Like others, I'm blown away by your amazing CAD modeling skills. I work with animators at NASA and I don't see this quality of detail in their work. Well done! Your design is impeccable, totally in keeping with the Leica look and feel of quality and craftsmanship. I'm definitely buying one .... oh, but first I have to purchase an M8.
TS ISAAC said:Since my last post there has been progress, but also some slowing as I prepare for production. At this stage I am seeking the best of enamel finishes, and have been through a learning curve with my shop, as we work through the nuisances of painting brass.
Thumbs Up model 1 and model 3 have received a few design refinements and those modifications to the design are seen in photos at the end of this post. The small opening to provide clearance for the hot shoe of the M8 has been changed from a through hole to a pocket only which is visible from the back side. This gives the Thumbs Up a smoother appearance when in position on the Leica M8, in my opinion.
The photos depict the Thumbs Up in a temporary CNC setup as we experiment with various depths of engraving the lettering. 0.35 mm deep seems to serve the purpose best, providing sufficient depth so the black paint wont fill in the letters but rather, will leave some room for the white paint. Deeper would be good for painting but produce excessive wear on the delicate 0.25mm diameter end mill that forms the letters. The CNC machine shown is not the final production set up, but just a display photo to show the model 1 and model 3 together in all their shiny glory. There are two Thumbs Up before being cleaned up, and polished.
The second photo shows the polished parts. Although pretty, the parts will then be sprayed with glass beads using high pressure air, to produce a uniform dull surface texture. After the glass bead process, the Thumbs Up will be submerged in hydrochloric acid to further etch the surfaces. This etching provides additional roughness at a microscopic level. This etching provides additional surface area to which the paint can adhere. It is that painting stage we now seek to perfect, prior to formal production start up.
Vicmortelmans,
I do not own a Leica II or III and have not yet modeled a II or III in CAD. Send me yours and I will give it a go!
The Thumbs Up will attach to the III, but will not fit flush to the top cap of the camera. It may partially block access to the shutter release, when viewed from the rear. It is my design intention to see the Thumbs Up fit the M4 and M6 as well as the M8. You can see a prototype Model 1 on an M6 in a previous photo. Your point is well taken however, as it the Thumbs Up would serve the owner well, on a Leica II or III. I am eager to give that a try myself.
JBTran,
I have thought about alternative finishes, but first I will prefect the black painted version. The black finish currently looks quite good on silver and black cameras in my opinion. Perhaps others like you would appreciate a chromed finish. I have also considered a clear coated poslished brass version. Any interest in that? Fininshing in silver paint or with chrome plating are possible, but the number of possible versions to stock would quickly double. How many should I produce?
Thank you Ttriolo
for your remarkable compliment. My CAD models and prototypes are most definitely for low earth orbit use, but if you know someone that wants to take one higher, I feel certain it would work. M8's in space.....can I take mine?
The 3D camera models did take considerable time to produce, and they quickly became an essential starting point to ensure a proper fit of the Thumbs Up to the M8. Once the 3D models are complete, they can be used in many ways. I enjoy looking back at some of my earlier versions if the Thumbs Up, and to see the design evolve with the suggestions from here in RFF.
Etrigan63,
let me recommend you get a Thumbs Up first, before buying any other piece of photographic equipment, as a catalyst for your other camera plans. To answer your question, I imagine the Luigi case may require a special design change to include my Thumbs Up.
GregGebhardt,
I have a collection of my prototypes now, and each seems to offer greater ability to hold the camera, with little effort. Both long and short versions offer the same improvement on my M8. It seems more a personal choice which version to use. Many thanks for your comment.

Above, a Thumbs Up model 1 and model 3, soaked in coolant oil in the CNC machine. We were testing the engraving depths of the lettering here and settled on 0.35mm depth.

Above: an imperfect Thumbs Up model 3, used for polishing tests. Note the poorly formed curved end and some excess polishing there. Although not a good CNC part, it served well for polishing trials.
