Rool off roof

Eric Watkins

Hi Dennis,

just following up on your recommendation on wheels and track.

I’ve looked at the site the wheels come in three sizes and at the price you quote I would think these are the 50mm diameter V wheels. The other diameters being 60mm and 78 mm  se

My Observatory is 3.6 x 4.2 m. with a Pent roof which is felted. Based on your experience which sized wheel would you recommend.

The track you mentioned has a round rather than inverted V guide.  Does this except the V groove wheels.

Many thanks,
