Got my new Dannmar lift installed. When I built the garage I was figuring on a symmetric lift. I ended up purchasing the asymmetric Dannmar 10ACX from Princess Auto. Easy to install and it works great. I have also attached a picture of the frame cradle pads I built. The factory ones were too expensive.

Very cool! what did you use on the bottom of the pad?

Never used them, but the reviews seem favorable, only downside could be they are 36 tooth

Works as you'd expect, only wish it was locking as well. Apparently you could retrofit the guts with 80-tooth components from Titan, but officially they said it doesn't work. :dunno:

I got stranded in multiple situation because of the sub 60 tooth count (wide arc), where I had to to go to an air ratchet at full throttle changing oil filter and removing a skid plate. 36 teeth is just way too low these days specially when you compare that to 168 tooth from propoint that is almost 1/4 or the arc length of the 36 tooth

Know your application, we have a few ratchets at work that are 20 tooth, still get the job done at the end of the day

I have a few 36 tooth Williams that are work horses. Those titans being as long as they are, the end of the handle will have to move a mile before each tooth click. I'm sure they gave them 36 teeth for strength because of their leverage.

Surface to surface I think that higher tooth count is generally stronger because of larger contact surface provided that the machining was done right

This makes a lot of sense to me. I can't find a link to back up my opinion but, less teeth = more strength and contact area, that's how I've always understood it

All I know is that higher splined axle shafts in a rear end are stronger than lower splines for the same axle diameter

When it comes to ratchets. There is also the factor of multiple pawl design which almost doubles the number of engaged teeth vs a single pawl

Don't think axle, think ring and pinion.

I'm not sure what you mean by rough machining. The 1st ratchets were crude tools that alleviated the need to remove a wrench from a fastener and reposition it. This was the primary goal of ratchets. They were 20 teeth or so until companies like SK started making 40 - 60 tooth versions.

When you think of the technology we have today and compare to a high speed roller bearing that has tolerances of .003" over temperature ranges of 300' or more and spinning at 10,000 rpm's supporting tons of force you have to wonder what took so long to make ratchets tighter. We are finally seeing precision made ratchets that can keep sufficient contact on 100 tooth multi tooth pawl designs to maintain strength and function. It's about time.

I got the the NANO PROpoint ratchets 168 teeth in 1/4" and 3/8"

As soon as I got home I took them apart

First of all they were not oiled with some traces if rust

But fitting 168 teeth on a 1/2" wide gear (used in the 1/4" ratchet) was extremely fine I have never seen any metal gear, knurl or machining done that fine before, maybe in a watch gear but that is brass with minimal loads on it

It was so fine that in order to feel the teeth you would have to do that with the edge of your nail, your skin just feels sandpaper

Whew, I hadn't heard of the 168 tooth rats. Guess I should have read posts from the front instead of starting on the last page.

You could also compare fine vs coarse threads where fine is stronger.

Remember that you have every tooth engaged on axle splines, and more but smaller threads on fine threaded nuts and bolts. Everything else equal, more smaller tooth engagements will be stronger. On a ratchet only one tooth may be engaged, the coarse one will be stronger. On better fine tooth ratchets, more than one tooth is engaged, so they may be stronger.
