Drilling an access hole in a Greenie

pmateosian · Post by **pmateosian** » Sun Dec 20, 2009 10:15 pm

I read several posts about drilling an access hole in the very early Mark V's that didn't have one. I took a stab at it and am going to attempt to post pictures. I used a standard bi-metal 3 1/8 inch hole saw, starting with a small centering hole layed out on the center line of the existing small holes that held the retaining tabs of the Shopsmith name plate. I then threaded some 10 / 32 threads on the existing tabs and fastened it back with an aluminum bar and two nuts. Not sure how easy these will be to get off for service, but it's my first try. If that doesn't work I'll use a gob of silicone or something like that. This is my 3rd shopsmith project. The first was a 10 er that belonged to my father in law. The next two are "greenies" that I picked up for 125 each. One of my greenies came with an access hole the other didn't. Both work, but I am tearing them down to have a look inside.

Welcome to the forum. Nice photos of your project. To get away from having to access the nuts in order to remove you access plate, take a look at how I accomplished this using a rubber grommet. Food for thought.

It looks good!! I know the tear down feeling from being in the middle of rebuild of mine. There is a tremendous amount of information here, and I am still in awe of it all. I will be doing a 10ER next as soon as I find a set of legs and casters for it. Then I want a Goldie or a Greenie or maybe even one of each to make a mini and a shorty out of!!!

Merry Christmas

I like the grommet idea. Is that an electrical supply specialty item or something that can be found at Lowes?

It's electrical supply but possibly a Lowe's , HD item also. McMaster has them also. Scroll down this page a little.

This will work well for you. Remember, the grommet acts like a spring and pushes the opposite post up against the side of the hole. With the threads you added to the posts, the opposite post will 'dig in' nicely.

I had tried using 2 grommets but was never able to get the second on engaged. I probably could have figured it out eventually had I kept trying but quickly dismissed the idea when I saw that the logo plate was being held on with the one.

I also used a 3 1/8" metal cutting hole saw. I use a flat 1" X 3 1/4" alluminum bar piece and drill and tap the bar for #10 24 screws that I use at the top and bottom of the original Logo cover in the center of the half moons.

As a byproduct, I have been able to take the plug removed from the headstock and with a hammer and little JB Weld to level it on the edges, they may a great jig saw table insert (3").
