Well, the table is on its feet now. The caster jacks work, but not well. A number of problems have come up – which Norm failed to mention or caution me about. There needs to be some slackl/space between the various pieces that make up the retractable casters… Norm says the caster panels should tuck under (and be suported by) the end stretchers (which they’re hinged to) – but without a little slack there, the caster panel doesn’t flop all the way down (which in turn prevents the caster jacks from flopping into place.) Likewise, a little space is needed (between the bottoms of the front/rear stretchers and the tops of the caster jacks) when attaching the two via hinges.
Anyway, as it is right now, when you lift the end of the table, the caster jacks don’t want to drop all the way into place. Their stasis is to hang about 10 to 15 degrees off of vertical:
That may not be a big deal – the casters still drop and are held in place and it rolls around as it’s designed to—but what is a big deal is that it’s really tough to raise the casters by pulling on the rope. This became even more true once I moved the MDF top in place.
The slide-out support for the flip-up work surface is done, though…
The shop-made drawer-glide with self-adhesive UHMW (Woodcraft “Slick Strips”) bearings are smooth and work really well. (I need to get a picture from the other end so the glide mechanisms can be seen.)
Tomorrow, I’ll be mounting the top and installing the flip-up shelf and maybe making the lift jack. (It’s pretty heavy with the top resting on it – difficult for a 76-year-old guy to lift the end so the caster jacks will drop into place.) I also need to install the lower shelf – and figure a way to make those retractable casters work more smoothly/with less effort.
