What would be the best short throw lens for a SuperSimplex in both anamorphic and flat? What I need it for would be my Acme dallies projector. I'm looking and a screen about 20 to 25 (at the ABSOLUTE most) wide by say 15 to 18 ft. at under 50 ft throw. I'm also looking at used if possible 'cause as always, money is tight especially mow. Any suggestions would be greatly appreciated. Thanks-Steve [Cool]

Isco Blue Star for the anamorphic... You can set it really well down to about 15 feet For the other lenses either the red or blue series is excellent. Rare to find rm used though.

Also be sure to install Positrol sprockets in the Super to keep any side weave under check. Also, Hopefully you don't literally mean you're using a Simplex Acme that it's at least a Super Simplex....

Dumb question, Mark: what's a Positrol sprocket?

Would this be used as an intermittent sprocket? Speaking of that, off the topic, can you still get pinned intermittent sprockets. I've been having a hard time finding an intermittent with a decent sprocket (most are pinned on). The only intermittent that I have with a screwed on sprocket, the damn flywheel is seized on the shaft.

True, pulling flywheels off on a Super intermittent ass'y can be horrible at times. Had to soak one down with Liquid Wrench one time to finally get the thing to break free when you get the lock screw loosened, shove the screwdriver in the center while trying to hand turn the flywheel.

Can your INT sprocket be turned around to wear on the other side of the teeth being the taper pin variety? For I heard that Super parts are getting hard to find anywhere.

On your question on "Positrol Sprocket" - check this page from Lavezzi

Use a gear puller.

Tim; you can't...it's threaded on and you must turn the screw with a screwdriver. Louis

Don't think the positrol is available for the Super intermittant.

IIRC that flywheel pulley is a left-hand thread too..so be careful. [Smile]

I've tried pretty much what was suggested. I should try soaking the end in liquid wrench. I have about 6 intermittents, all good, but the sprockets are pinned and I've tried flipping them in the past. Never really works well.

No Mark, I just spaced out, It is a Super, I MEANT to say Atlas not Acme dallies projector. Yes, you had mentioned installing Positrol sprockets in my Super once or twice before and the recommendation has NOT fallen on deaf ears, I, of course, will heed your mentoring and do that as cash becomes available. The Isco Blue sounds EXACTLY like what I'm looking for, and will do what I want it to even in confined spaces but I'm a bit concerned it may be out of my price range or at least take a while for me to gather up the cash to afford it ESPECIALLY if it's not likely to be found used. Do you have any other recommendations that would work maybe as a stop gap measure until I could gather the cash up for the Blue?

Nope, they're right handed threads - left to remove the flywheel off the shaft.

It's the slotted shaft where you turn left if you hold the flywheel to tighten. But, I go easier with holding the screwdriver and turning the flywheel right to adjust.

Positrols are available for feed/holdback and intermittett. However your intermittent must have a 5/16" diameter star shaft. These sprockets have a vkf tooth on one side and a wider special tooth on the other side that fits the full width of the peed. Hence there is no measurable sideweave that can be measured visibly. I used positrols on all my dailies units for many years with spectacular results.... There was zero problems with millions of tape splices either single or double sided. There also used to be positrols for the X-L but I don' know if they are still available or not...

Mark, look at the Lavezzi catalog again. They DO NOT have the positrols for the pinned style intermittant sprocket..looks like they do not have the pinned style available anymore either..better try Wolk.

The positrol IS available for the XL still...Part # L2SP31

A properly aligned Super will have NO issues of side weave so a positrol is a waste of money, even if it could be had. I do wish they made the VKF profile for a pinned sprocket though, now that would be worth the extra money.

Steve, replace the sprocket, make sure the lateral guide rollers in the trap are aligned perfectly with the sprocket (get the alignment guage from Lavezzi, part # AG-1)and make sure that the lateral guide rollers both turn freely with no side slop and that the spring-loaded roller can move freely. A TINY drop of Simplex oil on each end bearing and the center of the shaft where the two rollers spread apart will keep 'em happy.

Thanks Monte, I stand corrected. It has been years since I had my Super..and I wish I'd never gotten rid of it.

I always felt the super was not the best for registration if the gate tension was reduced to a sensible level now the E7 had a rock stable image with almost no tension
Some of the BL anamorphs can be disasembled and the slots lengthened to reduce their focal range

When I think of all the Simplexes and Powers I walked away from over the years and let get tossed in the trash, it pains me. I'd love to have an old Standard and a 6B for posterity.
