Thanks Guys for all your help. I am glad there are good folk to share this hobby.

 

Do we have a book scoop?

Yes, save your money, it's not too far ahead now.

I finally made the time to get my crusty pink motor back together. Found the correct parts to get back to stock. Not that easy as the post protectors are specific to that Mura end bell and the brush hoods are also only found on Mura motors. The brushes I install are shunted as I believe they were.I have other untouched motors and both used shunted brushes. One where the shunts are broken off, one complete.

 

The second motor is one I did partially paint and color match along time ago, I figured while I had all my motor parts out I would finish that one too.

I plan on finding small button head screws to seal the deal. Any leads would be appreciated.

 

By the way they both sound strong. I learned a lot thank,s to you guys.

Nice, just like what was my first racing motor 1970.

Those PCH supplied Koford end bell screws are exactly what I use.  I love them!

[Martin]

Thanks guys,

to use those Koford screws, what drill do you use and then will I need a tap, or do they self tap?

Paint them silver and these will look the part and be easy to remove down the road.

[Bill from NH]

Those threads aren't machine screw threads, so no tap is needed.

[Martin]

Thanks Bill, are you saying they are self tapping? What size pilot hole do you drill?. Got to get this correct.

 

I could experiment on junk end bells if the info is not available.

[Bill from NH]

I enlarged the photo of the Koford screws & the threads are too coarse to be  a machine screw. I've never used the Koford screws, only some button heads sold by TQ. I think I used a 54 or 55 drill bit for those.  You could drill some differing test holes in some scrap plastic to see how the Kofords fit in various sizes. I keep an old Sears screwdriver handle around for test drillings.

Or you can use a pin vise.

[Martin]

Thanks guys, I will make a fixture to support the motor at the correct angle and then use my mini drill press. I will start the hole with a drill the size of the can hole. This makes sure you get the hole on center.

Martin, this eBay adjustable angle block and mini drill press makes drilling these holes easy and accurate:

 

 

I'm an end bell hardware geek so I use this gizmo from Micro-Mark to tap the holes at the Korrect angle:

Perfect Rick, I had that pic in mind but could not remember where (in your posts)I had seen it.  Will order one of those. Pretty handy.
