I need to design some adjustable guides that will move on a lead screw with a hand crank. The problem I have is I don't have enough room to come straight out of the lead screw with a hand wheel. I need it to be 90 deg from the lead screw. I can't seem to find a right angle drive for a hand wheel. All I find are for motors which I won't be anywhere near the rpm. Any suggestions on where to source?

What are your objections to adapting a hand wheel to something that might not usually operate with one?
I am assuming a 1:1 gear ratio. Is this correct? How strong does this mechanism need to be? Are you lifting a truck or lifting a microscope stage?

Worm gear.

I'm not opposed to adapting I just couldn't find a gear box that wasn't expensive or made to mount to a motor. 1:1 ratio with same direction output. Its for centering a .080 thick sheet coil into the press right before the die. We haven't sized the rollers yet but on similar but much more heavy duty centering guide we have 2 osborn rollers per side with a radial load of 1620 lbs.

Sounds like you might want one of these? Handwheel connected worm gear turning an acme nut?
Same site has miter gear boxes, ie 1:1 ratio too.
