Why a Nasmyth?
Hi Ed,

It simplifies the mount considerably. I want to mount it on a mel bartels driven alt azimuth mount sitting on a stand which elevates it to a suitable height- a variation on the idea shown here (where they are using equatorial platforms instead)-

That's great Rod!

It's all about being comfortable when you are observing.
And I think that's what the Nasmyth design is all about.

Rocker Box

I did a bit today on the front of the rocker box. I started of by making a template out of 5mm ply so I could use it as a guide for the router.

With the template done I transferred the pattern on the front of the rocker box and drilled a few holes to make cutting with the jig saw easier. I didn't cut it right on the line but left a 3mm or 4mm overhang.

The way that I secured the template onto the board was with some double sided tape (it held very firm).

Using the flush bit on the router table, I took the excess material off and then used the radius bit to round all corners.

I think Ian and Rob might have got something out of it.

Thanks Phil, you would of had some reading to do
Ed,

I am really enjoying following the development of your scope. And you bet, I am getting a few ideas out of it and I will certainly be "stealing" some of them

Cheers,

The prize is the satisfaction in knowing that I can help someone along the way.
For me it's a complement seeing someone using something from this thread on their telescope.
If you can get something out of it......Please go for it!

Ed gets all his parts made by a blind man in upper uzbekistan

Ed I just wish this was all on a video - that you could have over dubbed the commentary and said what was happening when and why

I think everything so far has been outstanding, although the shapes for the rocker box have me thinking - was that to save on the overall weight of the unit?

It will all make sense when it is all put together. I wanted an artistic flair to the whole thing. It also allows for a bit of air circulation and if it reduces the weight so be it.

Every part of the telescope has to do it's job and the good part about designing your scope, is that you can experiment with the way it looks as well.

Hi Rob.
I've been extremely busy with other things the past couple of weeks but I hope to get back into it soon.

With a bit of spare time up my sleeve this long week end I continued on with the rocker box.
The most difficult part of the box was the sides because I chose to use sealed bearings (instead of Teflon and Formica) and the holes had to be made to accommodate them. I didn't want to much chipping on the edge of the bearing holes so I opted to make the holes first then the routing not the other way around, it worked quite well and with a bit of sanding it should come up nice.

Hi Ed,

Interesting that your using bearings instead of the standard teflon and
formica. I'm guessing your going to employ some sort of striction brake.
I'm about to think about the side bearing on my lil fella along with the
rocker box. But I'll be going with the standard teflon and formica, but
will be keeping an eye on how you go about it for ideas on my next
project : )

Good to see you at it again

regards,CS

Graham,

Didn't know the 1" formica at bunnings, will be over in Lismore on Friday so
I'll drop in and have a look. I'm using the original base board, actually I'm
using the plywood from the old setup the build the mirror box and rocker box
there seems to be some sort of avocado coloured laminex on the base board.
Apart from that I was thinking of buying some formica stardust @ $66 per
1200mm x 600mm sheet. But if I can get the 1" strips I'll have everything I
need to complete the job.

What do you have spare?

regards,CS
