« Part 7: Cleaning Tubes Part 8 of Shopsmith Restoration series Part 9: Electrolysis for Rust Removal »

A few days ago I tried to dismantle my Goldie’s quill assembly with zero success. I seriously wanted to dismantle this to clean it up properly – I’m sure a bath in degreaser would not be good for the bearing.

First I removed the whole quill from the headstock.
Next I removed the set screw from the spindle knob, but I couldn’t take the knob off the spindle. I managed to turn the knob on the spindle with tools, but it was very tight, and wouldn’t pull off.

So I asked the ShopSmith Forum members for some pointers. Which I got.

Here are a couple of pictures.
On this one you can see the score marks on the shaft that (I think) were the main reason the knob would not come off.

Check the crud inside the housing

In this pic you can see the corrosion I will need to remove, as well as the wonky clip on the housing.

I supported the housing with the spindle facing up and the spline facing down unsupported, and whacked the daylights out of the shaft sending it down out of the housing and bearing at the same time, but I had to ensure that I don’t damage the end of the shaft.

That’s why I have “soft” mallets in my arsenal. For this job I used an aluminium mallet. The mallet gets all dinged before it harms steel.

In terms of “whacking tools”, here are my favourites shown from left to right in order of force required.
Short handled claw hammer, Rubber mallet, Nylon faced mallet, Aluminium mallet, 4 pound hammer.

.

.
Today I removed the bearing from the housing and degreased and cleaned the parts (excluding the bearing).

The bearing feels very good with no apparent slop or play, and smooth rotation without grating or excessive free running.

As you can see, my cleaning brush will soon have to be retired.

That’s in need of a good going over! Is the first time that You tried to tahe it apart? Glad that You had some help from the forum . It’s a great time to replace any damaged parts, and seals and the like Do You have a good parts store that can match up bearings” I always fear that it i don’t get it together soon after dismantle, that I would not be good at rebuilding. Good Luck

You’re going to have that old “greenie” gleaming and humming in due time. Keep up the good work.

Are you planning to cut an access hole on the back side of the headstock housing? This will make periodic maintenance much easier. The older sand cast housings did not have this access.

Andrew - So do I :-)

OldDutchman - I was gifted this machine and a clone a month or so ago. It was in such bad shape I have to rebuild it before even thinking of using it. Unfortunately, finding a good parts store out in the country is not possible.

David - It had better be worth it. In fact I think it already is – I love mechanical tinkering, and it’s going to give me some awesome wood machines that I’ve been coveting.

8iowa - This is actually a 62 or 63 Goldie so the access is already there. In fact, I even have an extra access hole in the belt cover between the way tubes.

It’s fun watching someone going through the same things I’ve been through, although your machine appears in worse shape than any I’ve redone. I gotta give you credit…I think I’d have just kept this one as a parts machine. But, the worse they look at the start, the sweeter the feeling when you finish. Keep us posted. -SST

SSTom – My parts machine is a clone, and is in equally bad shape. Apart from anything else, SS’s are extremely rare in S.A. and shipping one from the US would melt my credit card.

Andrew – I still work on it most days, but nothing spectacular is happening. It’s mostly cleaning and filing small mechanical parts, and WAITING desperately for the ordered spares to arrive. My motor is blown, and it is out for a repair quote at the moment. When that is cleared up, I’ll post progress again.
