Author Topic: Strong/Ballantyne shipping out busted bobbins!? Dan Lyons Jedi Master Film Handler Posts: 698 From: Seal Beach, CA Registered: Sep 2002 posted 06-20-2003 02:33 PM                     My order from Strong came today, some of which were the parts to rebuild my busted framing coupler. However, the new bobbin they sent me has 1 crack, and 1 place that looks like it will snap with the slightest touch. Both of these are on opposite sides of the same "slot". This is the very reason I ordered a new one, my old bobbin was cracked like this all around in all 3 slots. Is there no quality control at Strong? Is this part considered to be "good enough" or usuable? I await your expert opinions before contacting my dealer.

Did you get it drop shipped from Strong, or did it come from a dealer's stock? Give them (or perhaps your dealer) a call and let them know what you have. I have had nothing but good experiences with Strong. They stand behind their products 100%  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 06-20-2003 02:46 PM                     Danny, Thats definately not right. Perhaps it was a used bobbin sent to you by whoever sent it....

BTW, the shipment came directly from Ballantyne in Omaha, no way this could have been a used one.

Thompson The Weenie Man Posts: 4718 From: Mount Vernon WA USA Registered: Nov 2000 posted 06-20-2003 06:07 PM                     I never install bobbins that are cracked. I simply do not trust them. But yet, I never received one from Strong International that was busted.  |  IP: Logged Randy Bowden Expert Film Handler Posts: 146 From: Portland, OR, USA Registered: Aug 2000 posted 06-20-2003 08:57 PM                     Don you are 100% absolutely right! Nothing wrong with that coupler, I have installed quite a few that look just like it.  |  IP: Logged Don Sneed Master Film Handler Posts: 451 From: Texas City, TX, USA Registered: Aug 2001 posted 06-20-2003 11:03 PM                        Dan trust me there is nothing wrong with the spline in the picture, question: you do know about the "DOT" on the end of the of the spline, & which way it came out of the coupler ??  |  IP: Logged Dan Lyons Jedi Master Film Handler Posts: 698 From: Seal Beach, CA Registered: Sep 2002 posted 06-21-2003 12:54 PM                     Just an update. Strong is shipping me out a replacement next week. As far as the "dot", I never noticed it; however I do know the correct way to reinstall these.

After all, this could be a benefit for alot more people here than just Dan. I believe this is Dans first major rebuild and any technical help anyone might give him I'm sure would be well apreciated...... I commend Dan on tackling it. For a first machine to attempt, he did not pick and easy one.........

Here is a trick....before installing the sprocket assy & intermittent, install the coupler on each shaft three or four times each to seat the spline grooves to the grooves on the shafts, this will make it much more easy to install on the machine...I install the intermittent first (do not tighten down the movement all the way), I re install the framing handle & put the coupler on the sprocket shaft & use the framing to seat the coupler to the intermittent, you may have to turn the sprocket a little to find the groove...once install, I tighten the sprocket assy & intermittent while turning the shutter by hand to feel for any binds...if a bind is felt, back off the intermittent screws & start to re tighten slowly while turning the shutter blade over unitl all is tight & no bind...the trick is to seat the coupler on the shafts before installing, this will prevent damage to the spline & make the installation much easier & faster...good luck !!  |  IP: Logged Dan Lyons Jedi Master Film Handler Posts: 698 From: Seal Beach, CA Registered: Sep 2002 posted 06-22-2003 04:54 PM                     Thanks guys. I agree that this is a tricky machine, but it was within my budget compared to other machines. Well, not all, but I have no interest in messing with a hundred year old Simplex. As far as that DoT goes, It needs to be closest to the outboard arm for the shafts to slide in correctly. Danny  |  IP: Logged
