|Thread: Searching for an Off-The-Shelf, Light-Duty, Rack & Pinion|
More great suggestions. Many thanks to all of you.
Thank you all for these excellent suggestions. I couldn't have come to a better place for advice.
I'm asking for suggestions, please, for an off-the-shelf, light-duty, rack & pinion.
It's for my Misses to raise & lower the roof of her camper-van, which isn't motorised.
The distance of travel is just under a metre, so a 1m rack would be perfect.
The maximum load would be 25kg, so I reckon a rack based on 6-8mm square bar would be more than adequate in steel(?), or 15-20mm square in nylon or hard plastic.
The tricky part could be the pinion. I'd like it to be held, fixed, onto the rack (except when screwed right off the end).
I plan for her to to drive it up & down with her battery-powered electric drill, with the right bit coupled to the pinion.
I'm not a mech-eng, so I haven't done any maths on this but my gut feel is that it's a viable plan. Any comments appreciated, especially where I might get the rack & pinion. I have access to a workshop, so I can adapt & improvise to a degree.
Many thanks, Martin.
