Re: Quarter Hitch somewhat rough altitude movement
That grittiness you feel I noticed from day one until now more than a decade later! Ignore it! I took the HH ( and SkyCommader DSC ) in a backpack ? (plus my SV90TBV in a checked Storm case) to OzSky in March 2009, along with a 36mm Celestron ortho, a 24 mm Pan and the then new Ethos 13; (and I also checked my Berlebach UNI 18 tripod, CRAZY Eh?) The Richest Field views were amazing in Coonabarabran, NSW. The mount just is near perfect for 60-90 mm f/7 or faster scopes (or a small 5” IntesMicro Maksutov which I once owned ). I did place a small riser between the top of the Berlebach Uni18 and the base of the HH to get near vertical mount clearance for my 90 mm f/7 SV90 TBV: I repeated that adventure in 2014 but wised-up and purchased a new Gitzo, Systemic-5 ?GT 5562LTS that weighs 6 lbs and collapses to 18” ( now unfortunately discontinued ).?

Makes sense to me. The slow motion controls feel fine, just a little rough when hand pushing the dovetail saddle assembly. I haven't yet mounted a scope, and I suspect that with some weight and lever arm I won't notice the push-to roughness as much,
Thanks for the advice. Lovely little mounts, super rigid! |

Re: Questions for QH/HH owners about my recently acquired Quarter Hitch
They are meant to function as three legs of a tripod and these three nylon contact points are meant to be the only points of contact between the base of the HH mount and whatever supporting structure ( pier or tripod ) you are using. This is per Charles Riddle. ? I own one of the first HH mounts ever made and had many discussions him on his mechanical designs. The original HH is a marvel… don’t try to improve on it! I treat mine with loving kindness. I use it with my SV90TBV.? At ridiculous high power with an Ethos 3.7mm I can manually track Saturn and Jupiter for hours!

Re: Quarter Hitch somewhat rough altitude movement
I’d leave it ALONE! The issue is with the mechanical ?“wearing” of the “hard” anodised surfaces. When using the slo-mo controls this sense of “roughness” is unnoticeable. ? You are likely to DAMAGE the contact surfaces by making them out of round. Then the slo-mo controls may not produce smooth, clean vibration-free and backlash-free movement. ?( and nothing you do after that will restore that functionality ).? Forget about this and just use the mount as is. On Thu, Mar 2, 2023 at 11:05 AM Mark Manner <mark.manner@...> wrote: Hi, I have a new to me quarter hitch mount.

And if so, any suggestions for what to use to do it? |

Hi, I have a new to me quarter hitch mount. It is very nice, super smooth in the azimuth, and smooth in altitude with the slow motion. However, it is a bit rough when hand pushing in altitude.

Thanks for the help, and the respository of information on here. |
