The barrel fo my 14" Ektar!!???

[Gene McCluney]

Very nice - I love wood. Richard Ritter should be impressed. What about the expansion and contraction of the wood between the lens elements due to humidity?

Nate Potter

If he has that saturated with "oil" as he says, the surfaces should be impervious to atmospheric moisture changes.

[Turner Reich]

Very nice indeed, you should get years of use for the Walnut "hybrid".

[Jim Galli]

Oh sure. too good for shitpipe eh? Better check out the poor man's Protar elements. I can see them now in dazzling birdseye maple.

[Gustavo]

looks like we may have to send Jim to the special house !

[Murray]

Damn, holy krap, and Great Googly Moogly, Jim!

We've heard of nutcases. but a nutbarrel?

Amazing.

[Turner Reich]

Funny how Jim Galli uses the thread to promote another sale of his lenses. I wonder if he ever sold used cars?

Anyway the "barrel" of Walnut is superb, how will you attach the lens board, glue or wood flange?

[Jim Fitzgerald]

Ok, some more crazy stuff that I had not considered before I made this thing. I posted this on the APUG forum also and got the measurements for the F-stops from a Commercial Ektar. I made some waterhouse stops that go to F-64. The front element to the stops is about 33mm. and the overall length of this thing is about 74mm. I was told that the original is about 74.75mm. Not bad for just eyeballing this thing. Like I said give me Walnut and I can do almost anything. Maybe I should build a Walnut car that runs on sawdust and invade the lens mine at Galli's and get all of those lens elements lying around. Jim will be so amazed with the car (Maybe it will be a truck instead) that he will get out the 8x10 to shoot it and I can make my move! Now that is a plan!! Sorry Jim as nice as it would be to have those elements I'm going to have to stick with my $ 45.00 Ektar. I have a lens board for this by the way. The lens fits very snugly into the opening. If I need to secure it I can put a set screw into the barrel at the back of the board. Very simple and effective.

Quite cool, Jim, and I bet it looks just lovely on your walnut 11x14! I'd worry about the oil off-gassing and sliming the inside elements; not sure what that would do to the AR coating.

Did you thread the wood, or let the lens threads grab onto a smooth surface?

[Hollis]

I made a waterhouse stop out of a business card from a mexican restaurant and blacked out by sharpie. Not as cool as walnut though.

Hollis, I did the card thing for my stops also. I decided with the Voigtlander that it was worth the effort to make a set out of brass. The door kick plate I have works great. I designed the opening for the Ektar to accept the same size stops. I now have a complete eight piece set that works for for both lenses. I did at one time consider making the stops out of walnut also.
