    Hopefully start work on this project next week, ive come up with a design for the telescopic part and ordered 20 bearings, main importance is no movement unlike a ham radio tower,

    The bearing will fit inside a cage made from four pieces of box section this will also be part of the hinge and leveling system, box section will run through the rollers and hold it 100% stable with dish on the top :).

    Ive been busy with other projects but hopefully i can get the tilt and telescopic part made and bolted to the base next week, the garden looks bare since the DH went,

    I have a few bits to start the fabrication i will have to pick a few parts up one being a 6x6 inch box section that will be part of the raising mechanism,

    Basically something like this

    Will be bolted onto the front of my existing movable base.

    Tested the sensor today it works fine then built the H-H back up, i need to drill the chain tension hole bigger and shorten the chain, i can give it a test and do any tweaks if necessary.

    Managed to find time to test the H/H today works like a dream nearly 3 minuets from one end of the arc to the other, i wanted it a bit slower but i am happy enough to leave it like this, i need to shorten a few bolts and do a few little tweaks apart from that its just about done.

    Over the last few months ive been collecting suitable used steel for the job in hand, basically the black box section will be made into a square cage using threaded rod, a bearings will be installed on every threaded rod x20 for the raising mechanism, the dish will be attached to the bigger square box section and slide up/down on the bearings.

    Hi spent a few hours on this project today, cut the box section to 7ft lengths cleaned it up then started drilling the many holes, ive decided to have a spacing of 3ft holding the dish pole i will double up on bearings top and bottom and single bearings in the centre,

    This is as far as i got today, i need to drill same again x2 for the bearings then at a later date after testing another set at the bottom for the tilting mechanism winch to attach to, this part of the meccano set will bolt to extra steel concreted in the ground for extra stability when the dish is up high for extreme DX at the ends of the arc.

    A few pictures of today's progress.

    @lincsat Hi Ian a couple of queries please, mesh, there is a right/wrong way to install it, if your just using C band it doesn't really matter but i will be using KU as well the pictures on page one of this thread are not clear and ideas please

    At first glance it looks the same any way up, running your hand down both sides you can feel it smoother on one side,

    On closer inspection you can see the steps in the side without the weld
    Mesh.PNG

    Above is smooth -------------------------------------------------------------------You can see the steps this side

    I can only presume the smoother side faces the satellite the holes do look slightly smaller as well i will measure the differences and report back

    Also the LNB any ideas of the frequency range please its a Precision blue thunders many thanks.
