No. The towers are not strong enough to support the strain.  I still have a problem with the motor.

I figured I finish the scene and then when I have time go back and rebuild the towers. The wireing is in place.

I to love the morning scene.  Only one problem.  I cant seem to duplicate it.

It was shot with a flood light turned facinng the back wall. The AV was set to 32. 10 second on the opening of the Shutter. The second pic was shot with the lamp turned directly on the scene. Same AV, same 10 seconds Of course I tryed to go back to the lamp on the wall. unfortunitly it was nice and clear.

Anyone who might know what I did right or may be wrong with an answer wil be wonderful.

Thanks in advance

Harold

Harold,

Thanks for the come back,,can't help with camera thing,,,but I do like the way it looks..

Some food for thought,,,,Did you ever take apart,a tube type radio? The kind that the freq. needle moves across the face of the radio Horizontally?? In there you will find,pully's and string,with a spring tensioner..It may spark you with some Idea's for your lift.....Just a Thought!!

Cheers,

Frank

That's an interesting suggestion.  Prototype chair lifts have large concrete block counterweights to add tension and counteract the weight of skiers, particularly of skiers like me.

What part of the towers isn't up to the job?  I would think that the brass tubing would be stiff enough.

The problem is in the crossbars. They were made using styrene tubes with a brass rod going through them for the rollers. I can not get a strong conection between the styrene ang the Brass Tower bases. I will go back and rebuild the crossbars with all brass.

I took apart an old printer and was able to get the Spring pulley for the top. I will only have to replace the bottom motor.  In the meantime I am finishing  the town with new roads and lights.

Any ideas on my screwed up photo?

 The morning one looks like it might be a touch underexposed - maybe your timing was off? Or you may have THOUGHT you had it on f/32. It's a lot less sharp than the clear photos, could have even been some slight vibration of the camera.

I'm thinking the photo was actually overexposed.  Maybe you had some other light coming in from the side, so that the meter didn't see it?

Try shooting through a piece of gauze, or a misted piece of glass.

Harold,

Perhap's you can build them double walled,,,one tube slightly,smaller,or larger,whatever the case may be,that fit inside one another,for added stress strength..  The Camera Idea's given sound viable..

Frank

The inside tubing is double walled. I put a brass tube through the styrene and followed with a solid rod. 

The only problem is the connection from the styrene to the brass.  If I get laze  ( Which I usually don't ) I will just cut out the area directly above the tower base to make the connection.

Harold,

As a side note,

When I mentioned the tube type radio,,it was not only the pulleys that are in there,but how they keep the string in the pulleys with tension on them,so they don't slip around the main pulley...that was my main idea,when I brought it up...As Always,keep plugging..

Cheers,

Frank
