Sorry Chip for my error. I also tried two Belleville washers small end to small end, but there was barely room in an OPW for that, so I don't recommend that. The force remains 7 pounds max but the

Joe, The video you attached shows your Oldham coupler gap is too large and possibly the retaining grub screws are loose based on the clicking noise and obvious gaps shown. There should be no obvious

Hi Michael, No, you misunderstood my post. The Bellevue discs used singly or in pairs requires that the large end of the spring disc presses against the outer bearing shell, not -[](- against the

8" at 1457mm. It was a good night! Consistent except for occasional turbulence. I'll post PHD2 logs later. Now to shoot darks...

I'd be interested to see your guidelogs when you finish this session. I recall you are shooting a 12" or 14" ota? wrote: -- Brian Brian Valente portfolio brianvalentephotography.com

Decent seeing tonight, but the PEC and mechanical stuff is playing into this:

Joe you covered a lot of ground there my friend. i definitely get you're frustrated and it sucks to spend a lot of time on a hobby that is just endless frustration I think if you look back on our

No-one here works for HGM (Scott’s company) nor do we have any means to influence him. Are you anywhere near Michael Herman? I’ve sure there’s a good chance he could adjust that for you. David.

Joe i didn't suggest you don't have mechanical issues, i just asked what your backlash was You also suggested you have northern backlash issues, which doesn't make any sense, mechanical or otherwise

First, back up the T handle screw a few turns and loose those two cap screws with an 1/8 Allan key then you should be able to lift the OPW housing/cover vertically. The only thing hold the cover is

HI (again) Joe! Usually people discover DEC backlash when moving south (i.e., calibrating via PHD). Backlash is not direction specific, it's when you reverse direction in guiding that it becomes

My graphs pre and post PEC from last night are below. I am feeling pretty good about the PE corrected result, and am tired of futzing with the mount mechanics, so unless someone else sees something

You have exposed the coupler. Terrific. As you rotate the motor, the coupler will turn. Just stop at positions where you can tighten the 2 setscrews per metal part.... if they are already tight, and

Hi Michael, My original layout 2-piece worm block straight drive G11 worked very well with two Bellevue springs arranged with the small ends facing each other. I got my lowest most consistent measured

Thanks Micheal. John Hobbs hobbs_john@...

Pardon the very rough sketch on my cellphone! I hope the curve of the Belleville washer is meaningful. The larger outer edge should push on the (sliding) bearing. That bearing inner rotating part

Michael: From these posts I am confused as to which way the Bellville washer goes. Please post or show me a drawing of the block with the washer and how it points; small end pointing to the Oldham

I forgot to mention one additional thing, a point of clarification on something Michael said:? on the Gen II OPW, even though there are screws in the OPW cover to 'fix' the bearing blocks in place,
