west coasters have to consider earthquakes as well as slippage in racks. 1)In the old days for permanent installs drilling first with a small bit = to avoid cracking and then up in size and finally a self-tapping screw = could be used to stop single tube rotation. 2) I had and sold an unknown brand (too narrow for my situation) where = the two part end couplings had matching serrated plastic teeth so you set = the angle while loose and then tightened the two parts of the coupling at = the angle you wanted.. I thought that was a brilliant detail, but no company name was on the coupling or tubes. If your 3d printing keep that in mind. lorne -----Original Message----- From: Andre Majorel [mailto:xxx-xxxxx@xxxxxx.xx]=20 Sent: April-24-18 11:20 PM To: xxxxxxxx@xxxxxxxxx.xxx Subject: Re: [AH] A frame stands / Jaspers etc On 2018-04-23 23:20 -0400, Michael E Caloroso wrote: > > The 1.5" aluminum tubing with those metal T-clamps will hold any=20 > > synth you put on it I'm quite certain. >=20 > Don't count on it.

You could take an = old bicycle inner tube, cut wide rings into it, thread the tube into the = rings and tighten the clamps over them. -- Andr=E9 Majorel http://www.teaser.fr/~amajorel/
