glacially slow basement machine shop build

So I couldn't get the back gears to work. If you flip the lever to engage the countershaft the chuck won't spin like it's trying to be in two gears at once.

The only other thing I can move its this pin. Based on the motor and gear reduction setup this comes with I don't thing the back gear has been engaged since the 1960s and the transmission was used to control speed. I'm hesitant to just crank on it but my question is for anyone with a similar setup is should I try to twist this pin, slide it sideways or pry it upward?

The last two pics are the transmission setup. The frame the trans sits on is way taller than it needs to be so I'm gonna make a new one. It's a T96, probably from a Stude', with a homemade flat belt pulley replacing the output yoke and a gear reduction box of some sort on the input.

That pin should pull out then you can move it towards the center and disengage the front pulley from the low range gear/spindle.

Out as in move it in a direction parallel to the ways?
Looking at it on my computer not the patato, it might unscrew a little to loosen it up. It is slightly different than the ones I have dealt with.

Normally on older lathes they pull out (towards to tail stock) and slide toward the center of the spindle. You can see that the hole it is in is slotted. One side is locked in high and the other side freewheels so that the low range gear can do it's thing.

Since it has a square on it, it might have to get loosened some to move it.

I've stuck a wrench on it and given it some pretty solid left/right taps with a hammer to no effect. I couldn't really get under it to pry upwards well but sticking a tiny pry bar under the corners of the square didn't do anything either. I'll shoot some penetrating oil in and hit it harder later today.

Between the motor pulley ratio, the gear reduction before the trans and the flat belt pulley ratio I don't really need the back gear but I want it so I can ditch some of the existing gear reduction and get higher speed without losing low speed.
On my little baby Crafstman, there's a pin just like that locks the bull gear to the main pulley. It just slides in and out by hand on mine.....but my whole machine could probably fit on your carriage.

Given that it has a sqaure head, I'm leaning toward it being able to turn to loosen, and then slide inward to disengage. Might need to give it a little encouragement with some heat.
Using low range keeps the belt from slipping under heavy cuts since the gear reduction is done after the belt. Might be useful to have if you plan on some serious material removal.
Got it freed up. It just took more force than I wanted to give it seeing as it's over 120yo and they didn't exactly have readily available grade 8 hardware back then. Back gear engages and disengages as it should now. I spent today driving out to pick up a bulkhead for my friend who's house doesn't have one.

I still need to build a new motor mount, get the carriage on the lathe, slide it toward the wall and level it in before I can start using it. It sounds like a short list but each one of those is at least a day project and I've got at least a couple weekends of wrenching on the shitboxes queued up that I need to find time to do as well.
cool project. I feel sorry for you when you move.

At least he has a walk out basement. Last month I helped move a south bend 10 lathe, bench top mill, sanders polishers, big fucking table saw drill press half dozen cabinets and 40 years of hoarding out of a basement shop. 1 step at a time. glacially slow basement machine shop build
Funny you mention below grade basements. My friend who's been helping me with some of this stuff has a basement with no outside entrance and I just picked up a bulkhead for him. He does fine woodworking and some light metalworking one of our summer projects is to dig and pour him a bulkhead entrance so that he can accumulate basically the same list of tools you mentioned.

Of course since we're not lazy bottom dollar contractors we're gonna dig a full width hole, pour a flat floor and use removable wooden stairs so he can gantry cane things in and out.
I bent some tubes and started on the mounting bracket for the new motor mount this weekend. Sorry no pics, I'll take some when it's done.
