If one has thrown away the shipping box for the CGEM, how should one go about packing it for shipping?

Thanks

Bart,

I've reduced both my RA and DEC rates to 5. It takes a little more time for the mount to complete a goto, but it is quieter. I've not had any problems using these reduced rates so far. Good luck.

The simplest way is to find a good sturdy box (double thickness if possible) that is a good bit larger than the mount (20x20x12 is good). Wrap the mount head in at least a couple of layers of large bubble wrap and wrap the hand controller in bubble wrap as well. Cushion everything as well as possible using peanuts or other packing material in the box. You want the mount to move around as little as possible.

The only way I would allow a pack-and-ship place to do it is if they are going to use the one-shot foam packs that expand to conform to the item being shipped. Otherwise they will just drop it in a box of peanuts which is insufficient.

If you want to get hard core, then what I do sometimes is get a good box and line it with styrofoam that you can get in sheets from Home Depot. Doing it this way, you can make a custom-formed box for the mount.

Finally, if you have a Pelican case (or similar) that you store the mount in, it can be shipped in that case. However, shipping may cost a little more this way.

Could I be biting off more than I can chew by thinking I could DIY?




Sounds like you made your decision to hypertune and I don't know about the CGEM but here's my 2c.

I got a LXD75 a week ago and was immediately frustrated with its performance, just for visual. I'm fairly mechanically inclined so with the help of the internet guides went for it. After 4 days of working on it for a few hours a day then taking it out at night to play with I have it set up ok with what I think is a balance of minimal lash, minimal play and minimal drag. It's definitely not perfect but it would take full disassembly and a lot more work to make any better. I did replace a few screws.

The trickiest part of the operation other than just figuring out how it all worked was that a lot of the performance gain came down to fiddling with torques on screws. In the end I'm glad I did it myself because I'm kind of expecting that I'm going to have to periodically keep tweaking things to keep it working well and I know what to do now. Also someday I'll probably have another mount and it seems I can expect I'll have to do the same again with it.

Good luck either way,

Doug

Thanks Ed, I thought it might be something like this and you've got the best possible pieces/ parts in the kit already.
Apologies for calling the washers 'nylon', I knew they were Teflon and just made a tired mistake.
They really do work fine, its only my imagination which has them compressing or getting scraped up and needing replacememt down the road. On my EQ6 the surface which the bearings ride on is rough and pitted. Not super bad but the casting has bubbles in it and some of the holes are exposed with rough edges not suitable for any bearing really. I used JB Weld on them like you might use bondo to smooth the surface, fill in the couple of pits and get any snags smoothed off and that worked ok. I cant help but think there is a better solution for washers with some creative thinking like on the above post mentions thrust bearings.
Still not complaining though Ed.. I'm super happy with the positive changes I've made with my mount and this Hypertune kit. The fine tuning/ adjustments to the slack in both axis' was priceless as were the new bearings and all of it... All slack is gone and I had a good noticable amount!

About the tripod.. I'm on a pier now days. Did you mix me up with someone asking about the tripod? Be sure to get back to that guy:-)
I should be able to post some images in the CCD forum really soon, perhaps by this weekend so keep eyes open for that. Thanks again, its a wonderful product!
Dan

You're right. I sent that PM to the wrong person. I thought it was a little strange that I was sending it to you in the first place.

The holes in the casting are definitely common. As long as the surface is smooth to the touch (i.e., no noticeable snags) I don't think they represent a problem. If there are snags though, then the surface definitely needs to be smoothed out and you are correct that something like a body filler would probably do a good job if the holes are really bad. I haven't run into any that bad yet and I would hope that those would not normally make it through QC in the first place.

Hi there !
I just tweaked my CG5-GT as well, and noticed something.
Sorry I dont have the cash at the moment to get the proper hypertune kit yet, but here's my finding, and a few subsequent questions :
I strated remounting the DEC shaft and noticed the plastic washers wouldnt really fit where they should have for some reason. The one at the bottom of the teethed wheel was OK, but the one on top just would get squashed when I put the shaft back into its housing.
So I just removed the plastic washers alltogether, applying quiet some amount of grease instead. And guess what ? The shaft is turning WAY more smoothly than with the plastic washers...
So here's a question though : I have noticed that the little screw that allows to lock the numbered dial at the bottom of the dec axis, just where the counter-weight bar goes, if screwed in just a tad bit too much, would rub against the lower part of the dec shaft, so that after 1/2 turn of the axis, it would just stuck the mount. Unscrewing it a little solved the problem.
The funny thing is that i dont rememeber it was doing this before i took the mount appart. Not that i really paid attention to it beforehand, but i was just wondering if I had done anything wrong.
What other problem did I run into ? Puting de DEC part back together. Unless I put a LOT of lithium grease that i've been using for this, the teethed wheel and-or the 6006 type bearing wheel would get stuck into the housing. A real pain to unstuck. I'm not sure i didnt damade this sealed bearing in the process and was wondering if that could be purchased somewhere as well ? Any reference - site you could point me to ?

Best regards,

Ed,
Have you considered making a punch and die set to punch out brass shims from shim stock? I made one out of a piece of Lexan and aluminum for .002 to .010" and steel for .010 and up. Just a thought.

I've have looked into this in the past but my need to be able to cut custom sizes and shapes keep me with the blade cutting and Teflon. There really would be no added benefit to go with brass and the materials cost as well as the equipment costs (punch press) and the increased production time (punching one spacer at a time) just don't support it. I am also able to maximize the use of the Teflon by cutting different spacers and bearing within each other to reduce waste but makes for complicated dies (that's were laser cutting would be better). I have farmed some things like this out in the past but that is quite expensive.

Ed,
I didn't consider different shapes. The dies for that would be expensive.
Another thought is water jet. In the past I bought a lot of custom hydraulic seals from a company called Seal Jet. Not even sure they are around now. They could cut most plastics.

I have finally gotten the drive completely adjusted on my CGEM, and I have to say, it seems to be incredibly smooth, now.

What it took was having power on and doing slews while adjusting the drive set screws (side with the drive bumps loosens, far side set screw on the round area tightens). What it really needed was to have the four cover bolts loosened to allow the drive to move. They are shipped gorilla tight (never get bolts this tight). With them gently snug, it was possible to have the drive backlash free, yet free spinning in about 5 minutes. Then tighten the bolts down in a diagonal pattern to keep it from moving. I spun itg through a few 360s to make sure everything was happy.

Do you really need to send it off and pay $325 for that?

Water jet cutting is certainly another method to use for things like plastics and if I move up in equipment it is a likely method I would consider. That is one of the methods I looked at for cutting the foam for camera insulation but I went with a local company that did die cutting instead. A water jet cutter is a significant investment and, more important, I currently don't have the space for it. I like to be able to make things myself for cost reasons but particularly for turn around time reasons. If I need something for a customer that I don't have I can cut it now. It can take a fair amount of time to get things from another company. In addition, one-off parts, even when they only require a little bit of CADD programming can be very expensive. There are pluses and minuses to each method but as my business expands I'm sure that the equipment I use will expand as well. I already have a 3-car/no-car garage/shop that my wife loves (and that doesn't include all the stuff that has taken over the house).

If that's all it entailed, I felt confident making the adjustment, and I didn't mind voiding the warranty by doing so, then I certainly wouldn't pay for it. I'm glad your mount required so little work. That's one less that I have to worry about.

For anyone that wants complete instructions on how to adjust the worm gear on the CGEM and Atlas/EQ6 mounts, I have posted them in a pdf file on the appropriate Yahoo groups. No charge.

There are a lot of us who don't have free time to play with mounts. Sending it off to get the job done right, by folks who know what they are doing is a good investment.

That is great advice if you consider the expertise a guy like Ed has developed doing the different types of mounts he has hypertuned. If you are not comfortable the with type of work or do not have the time and or tools, the expense of shipping the mount off to an expert to do the work is a wise choice and will save you some angst! Well worth the extra $ IMHO.

What I describe doesn't void the warranty. No parts are taken apart, no bearings unseated. All it is is a little bit of adjustment.

It does not void the warranty if you don't tell anyone about it. If you decide to make those adjustments, be sure to not tell them if you have to send the mount in later. I guaranty you that they will consider the warranty void. I think that is wrong since the mount is clearly meant to be adjusted in that fashion but that is their position. I'm sure that is because you can damage the motors (if nothing else) by doing it wrong.

For anyone considering making the adjustment, as soon as the gears bind, STOP SLEWING. It is possible to tear the teeth off of one of the gears in the motor gear box if you continue to slew the axis with the worm and ring gear bound.

When this became my full time employment (not by choice at the time but I'm glad for it since I like this a lot more than what I use to do), certain sacrafices had to be made. The garage is one of them. I'm just glad I have the space I have since this economy really doesn't support leasing or buying more. Now I have to get the air conditioner installed out their so I don't have to roast as much this summer as I did last summer.

The CGE is in many respects and easier mount to work on since it is a better design in most respects. The tough part is getting the worm gear alignment right since it does not have a good system for that. I have the filming done for a video but I haven't had the time to do the editing yet. Another thing on my long list of things to do. I'm also working on a cable upgrade for it with the prototypes being manufactured right now.
