We all have auto-loading projectors but have many members seen a Japanese Hokushin SC-10 in action?
I have one of these and film friends are always astounded to see it loading a film.
I bought it on eBay. It wouldn't work correctly but my engineer soon fixed it.
The model shown in the video is an earlier mauve model with one tone control. Mine is blue and has two tone controls.
The commentary is Japanese (?) but that is not a problem as the visuals are very clear.

I must admit I didn't see that loading system coming!
Very clever [Smile]

I used to own one. It was very kind to film but being only two claw and rather noisy, I got rid of it. Loved the loading mechanism. Very cleverly thought out.

There is no need to trim the film which is placed under a spring clip and held in position by pins through the perforations.
I don't consider that mine is in anyway noisy. It, of course, has had a service.

Wow that is really cool! A friend of mine has a Hokushin 16mm projector but it is different than the model in the video. His loads in more of a standard manner....I've never seen one like that. Thanks for sharing.

The automatic threading is quite extraordinary. It does break at some point since there is quite a lot of power needed to move the arm, film and lens at the same time.
Edwin van Eck has created the part using his famous 3D printer. Hokushin Threading gear if you ever need one the link is above.

I had one of these a while ago that I bought from the late great John Ferrari. Fascinating to watch the threading mechanism and a good performing projector.

Take always care for you fingers. Many users got injured by threading arm. There is no safty-clutch employed!

But is is a nice maschine and very relaiable. Visitors are always impressed to see threading arm in action.

That's the craziest auto threading I have ever seen! I watched it 4 times. It's so smooth running. Thanks for posting the link.

There's one on eBay now but it doesn't have the crazy auto thread arm.

That Hokushin as posted on EBay is worthless really as the loading arm has been removed and the BIG black knob seen on the lamphouse cover is fitted to the shaft that SHOULD carry the loading arm.
My guess is that the loading mech gear inside has broken & the seller or a past user has simply removed it to flog off a unit that can only be loaded manually...NO big deal but the machine is certainly NOT worth what the buyer is asking.
For quite some years I used a pair of those units doing mobile 16mm shows & I found them to have better light due to the shape of the shutter than the TQIII Bell & Howells I also had. Plus they were far easier to load on the run quickly and very easy to unlace if ever needed to in a hurry.
I did 20min reel changes using a control box I made up that switched lamps over as well as the audio as the changeover cues came along often pushing the image to 5M wide outdoors using the ELC lamp GE Multi Mirror type. Had a stand on the back of my ute that the machines sat on with a pair of big column speakers either side of the screen fed with a 30W per side stereo amp & would park the ute about 30m from the screen & away we would go.
Sometimes screening to 200 people.
Never ONCE did those Hokushins let me down & the kids were fascinated by the Circa Load action to thread up.
Only negative was the crude framing that moved the image up and down on screen so any adjustment there meant you had to either raise or lower the projection angle..other than that they were bullet proof.

Hello all,

For a 16mm film lover, I am fabricating the plastic gears for the Hokushin SC-10 projector. The first 3 are ready know and I am putting these on our webshop.

I have one question, does someone know the spare-part number of the original gear? I don't have the service manual for this projector yet.

Posted by Edwin van Eck (Member # 4690) on August 30, 2017, 09:41 AM:

And launched today the newly fabricated anamorphic lens adaptor for this nice projector!
