Morgan Pivot Polisher Sherline adapter base.

[Albert Rambaud]

Could someone please measure the center to center distance of the two mounting holes on the Morgan Pivot polisher Sherline adapter plate. these are the two holes on the left and they are clearance holes for 6-32 screws. Any help would be greatly appreciated.

I don't have one to measure, but If your looking to mount it, Harbor freight has a set of hole transfer punches for $11.00

Place the punch in the hole, give it a tap & it will leave a dimple on your mounting plate indicating where to drill.

BLKBEARD,

Thank you for the information. My problem is that my pivot polisher only has the one hole for the clampdown screw and was too early for the Sherline adapter plate. I do not have the plate either. I will have to locate the other hole and drill a tap drill size and then tap a 6-32 thread. I have contacted the Morgan Clock Co and he is very swamped and may not be able to find the adapter plate they sell for a while if at all. If some one had this plate and could give me the dimensions I could drill and tap the hole and if the Morgan Clock Co does have the part it will screw right on.

It doesn't look overly complicated to make a plate.
You could drill and tap it to fit.

Tinker,

Thank you. Yes I have duplicated the plate to fit my Sherline cross slide. In fact I have made an adapter to fit the lathe with the motor for the polisher attached. The spindle to the right of the polisher is there to keep the polisher true since I only have one screw through the bottom of the plate to the polisher. This works great on my Sherline but it limits the polisher in case I wanted to use it on my jewelers lathe. I want to duplicate the holes on the bottom of the polisher as close to original in case I happen upon a original plate. My motto is to alter the replacement piece, not the original part.

That makes sense. I tend to think function first but
you have a very good reason to want the measurement.
I looks to be a great tool.

I have had a Morgan pivot polisher for a few years and sadly it stopped working a week ago.

How does the Morgan pivot polisher compare to the Rolimat? I know the Rolimat is more expensive but does it actually do a better job?

Brutusamiga,

I really like my Morgan pivot polisher. It really does a good job for me. How did you like the job yours did? Do you have the polisher with the brushless motor attached. If you do there is an easy fix. Purchase a brushless motor controller on eBay or amazon. If you wish more detailed information email me. By the way do you have the Morgan/Sherline adapter plate.

If you can post a video of your pivot polisher in action sometime, I'd be interested to see it. I just checked youtube quickly and came up empty.

Thanks

 

[Albert Rambaud]

I will post something tonight

There are important technical advantages in how the Rollimat operates compared to the traditional pivot polishers. Using the Rollimat, the clock wheel remains stationary, while the carbide wheel rotates around it. As a result, clock wheels with pinions or the brass gear near the pivot are easily done without fear of breaking a pivot. The clock wheel is not chucked into a lathe. So wheels such as a warning wheel with a pin sticking out is not at risk. There are several you tube videos on the motorized version. We have a very short video on Hand Rollimat we carry. It is designed to be hand cranked, but we attached a small lathe motor to it. We believe the advantage to this model is that there is more control over the speed and the work. It is also about a thousand dollars less expensive than the regular motorized Rollimat. If interested in seeing it, kindly contact me at butterworth@butterworthclocks.com
