Testing the fit

The van conversion is moving along. Due to insurance requirements I had to pull seats from the passenger compartment, so this was the starting position:

The intent is to lift the bed high enough to allow for storage underneath, but I’m nervous about stability. Here’s the first attempt:
Unfortunately by the time I got the unit set up a storm was rolling in, so the image is a little dark, but I think the main idea is clear. The base is over 30″ high, with a further 6″ for the foam mattress, so I will need to provide a step or two in order for Daniella to climb aboard (I’ll need a little help myself!).

I will have to raise the mattress another inch or so – it’s a double, and is just slightly longer than the inside of the van is wide, so I can either raise the mattress so that it encroaches on the window “sill” area very slightly or cut the mattress to fit the limited space available. Cutting is irreversible, so that isn’t really an option.

This part of the project allowed me to give my router table a workout, and it worked out quite well, along with the Porter & Cable 1 1/4 HP router. I can’t say the same for the Bosch palm router I used for other parts of the project, as the collet came loose a couple of times, allowing the bit to drop slightly while I was cutting a slot. Perhaps the bit’s shank was a little undersized so that the collet couldn’t tighten properly. In any case, the net result was a ragged cut, and I’ll have to do a little work to smooth it out.

So far I’ve managed to keep everything removable, so in a pinch the van can be restored to its original condition with the exception of one row of passenger seating. That will change once I start adding electrical connections, but I will continue trying to keep changes minimal.

If it matters, construction is in 1×2 maple and 12mm maple plywood, and is currently held together entirely by glue and friction fitting in slots routed into the 1x2s. The mattress base is built from 1×4 maple spanned by a set of slats from IKEA. I’ll peg everything later, and probably reinforce the interior corners with further bracing.

Stay tuned…there will be more!

Increasing mobility

When I first moved to my present house skies were typical for an outer suburb – not very dark, but acceptable. After a while I built an observatory because I was having difficulty seeing Polaris and setting up and aligning was taking longer and longer. My thinking was that with a permanently aligned scope I would be able to do more on shorter notice.

As a notion it wasn’t totally wrong, but I forgot the astronomer’s curse, and no sooner had I committed to a permanent observatory than construction of a major shopping mall began a couple of miles away – to match the searchlights that sprang up from a flying-saucer-shaped cineplex a couple of miles to the south. Skies have gone downhill even more since then, and I’m looking at other options – specifically, at ways to get to distant observing sites, spend the night (or a couple), and return home in daylight.

So far, I’ve decided that a modified Sprinter van will fit the requirements. The van has been purchased – see the picture below – and I am fumbling for a design which will work. I’m building a preliminary version which will become the end design if things work out, or be further modified if they don’t.

My new-to-me 2007 Dodge Sprinter 144-inch wheelbase passenger van

The design will have to have storage sufficient for loading up at least one scope, mount, and associated cameras and accessories, sleeping space for two people (Daniella will be with me occasionally, and the van won’t be exclusively for astronomy), and enough ancilliary support to allow independent living for a day or two. Some of the sites I am considering have food, power, and washrooms available, some do not – so I will try to prepare for those which do not. Few (none, really) of the sites are happy with noisy generators, so any power I bring with me will have to be very quiet (ruling out the relatively inexpensive diesel and gasoline generators I have seen). Space is limited in the van, so the full washrooms (shower and toilet facility combined into one enclosure) seen in commercial conversions will be tough to squeeze in. And finally, Daniella wants to accommodate two or even three additional passengers for times when we are using the van to visit other family members around the continent. Oh, and I want to minimize the number of times I have to punch a hole in the outside of the van. I think these are tough specs, and I not at all sure I can meet them all. More later….
