Looking very neat so far. Useful pointer for the mount fittings, too.

Graham from Astotec has mailed me, EQ6 top plate should be with me on Friday. I think this is a much better setup than my original plan which was to put a "billetparts" EQ6 adapter on the top plate

Less is best :clouds2:

I can see the sense in putting it somewhere nice and warm where there's easy access to power, but I'm not sure how you're going to get to see any of the sky.

I like those wheels and track. Where did you get them from?

An interesting thread petrol and one I'm sure many will benefit from. I agree with Chris that system looks good and I would be interested to know where yougot the idea from.

The wheels are from a second hand video dolly (tracking) system I bought some time ago but never used. Other than that, I know nothing about it. I do however have quite a bit of spare track if anyone wants it. I’m sure it would be fairly easy for someone with a lathe to make some nylon wheels.

Blank pier plate from Astrotec has arrived. Have to say I am very impressed

Fitted the EQ6, this is better than my original plan of 2 plates and an adapter on the top plate

Very neat, very strong, very nice.

You know that there is absolutely no need to have a level mount? You'd actually have a stiffer system if you just bolted the mount to the steel plate on the pier top.

Those rollers are great.

Hi Olly, coming from you that means an awful lot to me. I often look at your pics in awe :rolleyes: I did know there is no need to level the mount as I read it in one of your posts :icon_scratch: I can’t however fathom out how to use just one plate. The problem is that this tube would have to be inside the pier.

Posted Image

Also the distance between the threaded bar inside the pier is less than the diameter of the EQ6 base.

Posted Image

This would cause the bolts to foul. I did consider using only 1 plate but came to the conclusion that the diameter of the pier would have to be huge in order to accommodate this arrangement. I might be missing something simple though :clouds2:

The weak point as far as I can see are the 4 threaded bars that go into the pier. I am planning on spraying the plates then filling this void with resin and setting the bottom plate on it before it cures. I assume this will improve rigidity?

Posted Image

I don’t intend leveling the mount properly, which is why I went for the 6 bolt mounting between the plates. Rigid over level.

As far as progress goes, I have cut the wooden blocks to go between the concrete pads and the main joists. I will fit a DPC (Damp proof course) to these but for added protection, I am soaking them in preservative

Posted Image

My main concern is how to fit the door; no idea what to do :icon_scratch:Tomorrow is spraying day. I know how to do that so an easy day

Thanks for looking,

Pete

That is looking stunning Peter.
You have put in a lot of hard work there.
When it is finished it is going to be a first rate set up.
Well done you should be very proud.

Thanks for the feedback :) More done today

Brackets to hold the base secure

Fitted a foam collar around the pier base, this is more for insulation than movement isolation. Measured and cut to size

Double sided tape on the back

Underfloor insulation – I cut the polystyrene sheets slightly too big and used a board to fit them

Cut them with this serrated knife

Built the frames tonight using 60 X 30 PAR timber. Screwed it all together with 4 X 75mm Deck screws.

Posted Image

3X 100mm solid brass hinges for the door. These are pretty big but there will be a fair bit of load on them

Posted Image

Have to say these really are “silky smooth” probably due to the washered design. I got them from B&Q, they sell loads of hinges and it’s hard to sort the good from the bad but if anyone wants some the packet looks like this

Screwed the frame on

Posted Image

Wood frame screwed to top. I have something a bit special planned for the roof, I’m not sure exactly how it’s going to work out yet but I can always screw some blocks on to increase the overhang on the sides

Posted Image

Then it jack-knifed

Posted Image

Well it’s a bit tight to the fence so I tipped it on its side to get the visqueen vapor barrier on. No joins, one piece did 3 sides. Nailed on with galvanized clout nails

Posted Image

Checked for clearance, 200p
