Luke's Garage & Gas Station

[Stuart]

Another area of my focus has been a modification to the winch I'm using in the outdoor repair area next to the garage. 

In my research I discovered that in the 1930's prior to the advent of hydraulic lifts a typical method of working under a vehicle was to simply hoist the front end up in the air and then prop some tall jack stands under the wheels to keep the mechanic safe during repair work.



The winch I am using has a hand crank and a gear system to increase the lifting advantage.  This system works okay, along with the block and tackle pully arrangement on the hoist, but, once the vehicle is up in the air, simply releasing the pawl to bring the vehicle back down to ground level while trying to provide a smooth decent would be extremally difficult and hazardous.  To allow a controlled lowering of a raised vehicle, I am adding a band type braking system to the opposite side of my winch.

This is a bit of a fee-lance effort.  I don't have a prototype to refer to, just some photos of various braking systems but I think my method is at least plausible.

I used SketchUp to draw this up in 3D and will see how skilled I am at printing this with my equipment.







My 1/12th scale winch.  This is a white metal kit from Ozark Miniatures, if I remember correctly.

Fantastic!

The founders of Ozark, the Hergets, would have loved to see your work. -- Russ

That looks great - I like it!
You seem to have got to grips with CAD and 3D printing very quickly!

[Stuart]

Thanks Ray, Russ and Frithjof.

Frithjof - Actually I have had a pretty long term relationship with CAD systems through the years.  What's new to me is the 3D printing process.  Fortunately, with the advantage of on-line tutorials and the help of generous guidance from forum members such as Lawrence and Volker, the learning curve has been less steep.

Thanks for all contributions each member brings to this forum.  Whether it relates directly to my particular circumstances or not, each of you provide a certain amount of inspiration to carry on and excel in this particular art form.

The brake should be printable, though I would use real wire for the rods.

[Stuart]

Thanks Lawrence, I was thinking the same thing with regard to using wire for the rods.

[Stuart]

The brake lever and brake band have been printed and temporarily applied to the winch just to see how it all works out.

Perfect. -- Russ

Those look really sharp!
