I am happy to see all the weight you are going to ask that mount to manage. I just thought of something you can put a gas tank in there rather than the scope to get things sortted with suitable weight... it would look strange but how convenient.
I have build one large mount (fork configuration) out of an old bed frame and wheel bearings and I should know not to try again really but as you know a mount to carry our little darlings capable of astrophotos is not cheap...I want to carry the 12 inch and 2 six inch scopes so a commercial mount would be over $20,000 I expect.
I will try and post the plans at some stage but in terms of real work its a pile of steel and bearings at the moment

Alex,

Most of the good home-made stuff begins as a pile of bits and pieces and junk. It's up to us to turn it into Astro Art.

You will usually find that the majority of home-made items are made with overkill in mind, so if you make a home made mount to carry a 12", it will probably carry a 14 - 16".

I think Darren (wombat) was looking at making a home made fork mount for his 12" as well.

If you want some very solid heavy duty axis bearing use car hubs. If they can carry the weight of a car they can carry a telescope!!!

Mine has Holden hubs and bearings on both axis and they glide so smooooothly.

I look forward to seeing your plans and watch it develop.

HOORAY!

Here is the finished product.

I couldn't take a pic of it all set up on the mount coz it's raining.

The rubber lining inside the rings is from Clark Rubber. I tried several densities at the shop until I found the right one.

I am very happy with the finished product and it ended up cheaper than I expected.


THE COST:

LPG Bottle rings - $55
Base Cradle & all welding - $40
Etch Primer & Black Paint - $20
Hinge (1 cut in half) - $4
Lock bolts & wingnuts - $2
Rubber - $22
2 Dovetail lock screws - 50c

TOTAL - $143.50

We sure are Astrew!

For those that want to make their own set-up like this, here is a close-up of the ring locks.

I used 1/2" bolts with the heads cut off, positioned in the brackets I made using the car exhaust clamp cut in halves, then drilled with a 5mm drill and pinned with 5mm Split-Pins. It is plenty strong enough!

Thanks Bert.

Answer to your question: Symmetry

Hope you are happy with the finished product
Bit different to what it used to look like. Thanks for giving me the opportunity of restoring such a fine mount.
