You mean you don't have a tailstock camera mount? All the cool kids have one... --jhawk  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 04-15-2007 05:14 PM                     Yea, the brushes for the 2M262 motors are the 1R234 - both from Grainger Wholesale. ..just follow the instruction on seating the brushes before using the motor (which the instructions for seating the brushes are on the back of the package blister for the brushes), or the motor won't be up to speed right at the beginning. Trick I use if I have a motor that died and the com is jet black and needs to be burnished back to copper, it to take a drill (cordless is more handier), remove the drive tire wheel assembly to make the drill attachment much easier,take off the collar off the motor shaft, put the shaft in the chuck of the drill, and with brushes removed turn the drill on and take some fine emory cloth to burnish up the com back to copper. It's a cheap way to lathe a com back to shine, but it works pretty good.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-15-2007 06:37 PM                     quote: Monte L Fullmer or the motor won't be up to speed right at the beginning. Actually none of the Strong/Potts(and pans) motors new or after rebuild run with the same tourque that they used to. This is due to a manufacturing change in the armature assy. itself. This necessitates changing the sleve on the end of the motor shaft which is threaded to a different diameter sleve depending on how it times out. I believe there is a Stong Service Bulliten on this change.

I have had to replace several of these over the past few years and have gotten replacement NTN bearings from Grainger, but they're not rubber sealed. I would also add that a "press" is also handy when trying to remove the bearing(s) from the shaft.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 04-16-2007 01:29 AM                     quote: Mark Gulbrandsen believe there is a Stong Service Bulletin on this change. Yea, I forgot about that update bulletin..that the 1/2" x 2" sleeve has to be used on these new mods since the rotation speed of these newer Ametek/LAMB motor has changed. (then, I forgot to mention on using that emory cloth, is to clean out the grooves with either a brush or compressed air..sorry on that, Gord..)  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-16-2007 03:58 AM                     quote: Jeremy Weigel Where do you get your rubber sealed bearings for the Neumade motors.

The windings are slightly different and the bearing is a better grade because of the sideways load. The Grainger motor will work, but you might have to readjust the payout head for proper speed. Now if you move that payout head to another deck, it might make the motor run too fast or slow. Also, note that the 'square' frame motor has been replaced with a 'round' frame type from Bodine. It's a better quality motor. The downside though is you must use a different mounting brackets for the top and bottom. The new top bracket is 11-0116022 and the bottom is 11-0116003 Rev F or later.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 04-16-2007 09:54 AM                     John, Actually the "Grainger Motor" we were referring to is the one for the Strong/Potts(and pans) platter. We get our Neumade motors from you.
