10 E Knobs

[JPG40504]

The 10 E which I recently acquired had these 4 sizes of 1/2-13 knobs.

Where is each one intended to be used? The possible places are:

1) To lock in vertical position(drill press)

2) To lock down(at the tie bar/head rest)

3) To attach tail stock to either tie bar end or hinged end

4) To secure an extension table to the tail stock.

5) ?????

I went out to my ERs to double check and 3 of your 4 bolts are slightly different from mine. But given all of the slight revisions throughout the ER's lifetime, I don't guess that's a big surprise. But here's what I think you have from left to right with an explanation of how they are different from mine.

Extension table support bracket. Nobody knows why it's so long. Yours is just like mine.

Headrest lock. Mine is shaped exactly like the extension table support bolt, but 2" long instead of 3". The tie bar fits perfectly around this knob.

Tailstock to base arm plate. Mine is 1-1/2" and the bottom 1/8" of the shaft is not threaded. I'm actually not completely certain this is the correct location, but I don't know where else it would go.

Vertical (drill press) lock. Mine is 1-1/4" and the end is more rounded than yours.

Here's a picture of my 4 knobs/bolts. The far left one (extension table support bracket) is just like yours. The others are slightly different.

Use the little one to lock into vertical. And none of these lock the extension table on an E. An E uses a wing nut, but you already knew that didnt you? Did I pass the 10E test? Is there a prize??

Ahh! You see although I have a 10E, there are some ER parts included and some missing. It came with adjustable tailstock and extension table, but without the 'original(E)' non-adjustable tailstock with studs/wing nuts. The 'studded' tailstock still needs to be secured with one of these to the base.

No prize,but Thanks to you both!
