I'm not worried about them fitting their brackets, Wayne. I've not made brackets yet.
No, I tell a lie, I made brackets x2 a long time ago, but they wouldn't fit anything bigger than a broom. Call them a test run.

The sight asembly is 90% together now.

I still need one last, but significant piece. It's the one that makes the lateral adjustment possible. If I can't find one, I have to make one. I really don't want to do that.

Its looking very good Tony , you will find its quite a cumbersome and awkward thing once its together and very easily damaged and knocked.
I would recommend making up a temporary stand if its going to be in storage for a while .

Tony. I notice on the hand spike photos Rob posted, that the machined, tapered end goes quite some distance into the steel pipe. At least to the 9 inch mark, or a little further. Seems held in place by two pairs of rivets: one set at the 9 inch mark and a second set 90 degrees offset, closer to the end. I suspect these inserts needed to be far enough up the tubes to cover the point of maximum torque on these hand spikes to avoid kinking the tubes in difficult situations.

The brass end caps would not be so critical, with just one pair of rivets retaining them. These are probably at the mid point of the brass bit that fits into the tube.

Hi Rob, How many do you have available? I need 2 for the long 25 and 2 for the short 25 but would be happy to just purchase one if you have one or all 4 for sale. If you only have 1 available I will machine up the others.
Regards Rick.

I have a pair of these but they are my patterns if I need to reproduce any so they are not for sale ,sorry.

If you can drum up enough interest over there it is worth pulling one apart to have the inserts made up. The end caps were brass or aluminium.

I could possibly contact my machinist and find out the cost of running some more up as I am sure he will have the program saved.

Rob, I hope yours doesn't need repair, because if it is the same as mine, it will be a very porous magnesium that is ridiculously hard to well....apparently. My fellow said he kept blowing holes in mine, no matter how low he ran the amperage. He used TIG welding, and spent several hours+, and also preheated the surface to gain maximum weld. Despite this, he said he has a horror time, because cracking would occur with cooling. The difference in cooling down between the two dissimilar metals stressed the weld.

Another undesirable complication is that the sector piece inside hits the strengthening I had to apply for reinforcing of the repair patch. This greatly reduces the extent the sector ca travel. I believe I've lost about 45 degrees of movement. I do have a plan to retake some of that loss, by making change to the sector itself. That is assuming it can be welded. For that reason, I am looking for another of those pieces to make the change to. If I use my own, and cock it up, then I'm stuffed! Best to use another to play with, so if you have another of those, we should talk!

I will make a stand for the assembly, but will hold off for a little while, until I know whether I can get that last piece i need or have to make one. The former, I hope.

David, the quantity (and quality) of the information I've received from you guys should be a tremendous help in making that system. Your help is appreciated. Until i get my act together, I will have a little play with tidying up a ground anchor/spade cover I bought from Holland, or is tha Netherlands these days? My cover has some significant dents on it, but is very usable. The attaching threaded rod & wingnuts are still present and in reasonably good shape. As stated earlier, I'm grateful for every piece I buy, and i believe it was Rob N. that said original parts in non-perfect condition is FAR BETTER than starting from scratch. The spade cover, amongst a multitude of other parts, is not something I could EVER make!

For now, my sight carrier assembly is sitting on a couple of rags on my living room floor, for want of a safer place to put it. I think I have about a fortnight before my Wife gets sick of it being there. The canvas cover for it, will be made shortly. That's one of those 'inside' jobs that I can do, provided Mrs B allows me access to her sewing machine again. That is by no means guaranteed.

[David Dunlop]

Do I sense a 'date night' for Mrs. B might be in the works, Tony?

Jeezus man, we went out for lunch on saturday. Surely that's enough?!?!

Maybe I'll just buy my own domestic sewing machine.
