Quote:Im ready to buy one. It just looks right. Any chance I can pick up at NEAF?
Quote:What are projected delivery times like? Looks like a nice unit!
Quote:Alvin,I forgot to ask two questions for Gregg. 1)My Teeter uses the ground board as part of the encoder system for my Sky Commander. Is this platform compatible, since you remove the ground board to use the platform?2) How does it deal with latitude?Thanks,Jim

Quote:I think it looks good ,but I am a little concerned with the polar axes side sticking out so far.It seems it would be a tripping hazard in the dark as well as a general nuisance.

He uses his Sky Commander with his 25" on it. He just needs to know the bolt size and thread count and he'll make the hole to match it.

Quote:Is there away to adjust the legs for uneven ground use?
Quote:Gregg,Welcome to CN and good luck with this platform. It looks like a real winner.I posted a question earlier as to whether the platform has adjustable latitude or is it built specifically for the observers location?Thanks,Jim
Quote:Jim,I think I'll still be making them in 2 years. I am also considering a retrofit kit for different latitudes. Since the platform comes apart easily, the front piece for the polar axis can removed with 4 screws and replaced, then the top assembly is easily removed and replaced, just remove the pivot screw. It should take less than 5 minutes to do. I will also have these parts in stock anyway for the different latitude platforms so I would just need to figure out the pricing.
Quote:What exactly has to be changed to support a higher or lower altitude beyond what shimming can accomplish? I would have thought just the curved part or am I missing something?
Quote:Quote:What exactly has to be changed to support a higher or lower altitude beyond what shimming can accomplish? I would have thought just the curved part or am I missing something?The easiest way to do this is to replace the upper arm assembly, but you're right it's basically the curved pieces in the back, but also the angles in the front of the upper arm assembly. I'm planning on having a few of these for my platform for when I travel. So far I've been shimming and last year at OSP it was a 6 degree shim which is too much really.
