JD... I've seen them slip slightly... and create big problems.

so which do you adjust? the gears on the claw? or the shutter blade itself... adjusting the gear is making big incremental jumps... not fine tuning.

and I only find this phase problem with variable shutters on the REX.

I talking bout this >>>>

Other than the obvious Out-of-phase problems. is there a way to determine that your shutter is perfectly in phase?

I shot some camera tests and and some scenes revealed a phase issue and some were ok.... weird!

why would this be?

Arthur!

Thanks Tyler,

Hum... been watching ebay for quite sometime already... I can just make one with a couple of 7 pin Amphenol connectors and and button switch.

Thanks again!

I know of several but they seem hard to find..

Had a "time flow" once... wasn't easy to use nor simple to figure the setting status.

Anybody?

Arthur!

Right... I've seen all the electronics inside the EBM... I was referring to additional electronics inside the handle grip where an ON/OFF button is located. or is it simple pass through.

Thank you Roberto... I will try this then... my fear was there might be some sort of electronic inside... not knowing since I had not taken it apart... yet.

thanks again.

Arthur!

...OK, I'm working with Bolex EBM in a studio setting...the camera body will mount directly to the tripod or dolly.

I'm not using the handle grip that has the on/off button on it.

MY Question is:

Can I plug in my generic power supply (12.2VDC) directly into the camera? The on/off switch will be in-line on the cable going from the power supply to the camera?

This configuration will help me run the camera remotely. so what is wrong with the setup?

Thanks for your support...

Arthur!

Also recoat the worked surfaces or you may get internal reflections off the top and bottom edges onto adjacent frames.

Do you mean paint the inside edges matte black?

Arthur!

I made it out of a thin gauge sheet of the material, optical grade resin. very delicate to work with... damages easy... but I'd like to see the lines thinner...

I have the first prototype installed on a Bolex REX... eliminated the mask and have a line on the ground glass defining the exposed gate area.

I think the lines should be thinner...

Thanks Dom...

 

Is there scratching between the perfs or is it only the processing marks you're talking about? Can you see any bruising from the claw dragging back over the film?

I wanted to post a clip but the files were to big...

The Lab says it is not scratching... but subsequent test will determine that... as far as I see there's no surface damage in the film from the claw...

Yes, I have a jig, but like I mentioned but the focus was the main objective of this test... Also that was the last of my test film stock... now to buy more new stock.

Another still on checking focus

OK... the test is back... now remember this test was to see if there would be any bowing in the film and cause out focus areas... I used some older... very older crap film for the test so there are some process marks visible along the edge... The lab said it was just the effect of old film stock.... The GATE is a bit high, but I'm almost sure that is slop is the attaching of the gate... this was not calibrated at all... but that's next.

So, anything else needs adjusting?

Swap for keeps... just looking for viewfinder parts to make a periscope viewfinder for a Bolex.

Hello Tyler... So let me ask... why are EBM's not so popular??? it seem springs are just more convenient is that it???

that's electronic? or optical?

Hey Macks... any viewfinders?

Is that colour ? Wittnerchrome 200D is the only one i've found without markings.

Both color and B/W... just not sure the name... updates to follow!

The Movement Has Started!

Thank you Doug!!!

well, I've found a source for 16mm film with no edge markings at all... I've not received it yet but keeping my fingers crossed.

Hello Macks...

have any bolex cameras? lenses? what do you have?

Anyone interested is swapping cameras... Super16 Bolex REX5 for a Nikon 7200...?

Arthur!

OK filming is completed... in the soup now... if this all works out I'm calling it "Cinema16".... anyone have a problem with that?

Results back on April 4th... will post them... stay tuned!

I simply milled it out of steel...

Hey is this legal? I was going for an Ultra 16 gate,,, but I think I over achieved... I got this 6.25mm X 14mm with a nice 2.24 to 1 ratio.

What problems do you think are headed my way?

A!
