Agreed, but.... When I said plug for a mold, that was a bit misleading. It’s actually a plug for a buck to be used for panel beating...if it doesn’t work out as planned, then I can use it to make a mold. The plan B tank I have in mind (composite) doesn’t really lend itself to just glassing foam otherwise I would consider going that route...... but then I’ll already have the plug. At that point making a mold would be preferable just so I don’t have to sand fibreglass and deal with the mess and stink of bondo. I can pretty much do as I please around here as long as the bride doesn’t have to put up with any noxious fumes or stink, so worth it to keep the peace.
"Non urinat in ventum"
Spent the weekend modeling more designs and this one seemed to bend the best. The entire unit flexed together without any real hot spots.
Started tacking the braces
Need to get more 1/2" tubing

i like the work and design
at the attach\ment points the end pieces that the bolts go thru the best scenario is an outer ring of contact
simply using a chatterless countersink works fine
this pretty much eliminates what will happen eventually if not done
the surfaces will work ever so slightly over time and with the aluminum it will especially wear so that the joint wants to move andf rellies much less on the friction of contact but of the modulas of the bolts
so that the contact is an outer ring about 3/16'' wide
another way to do it is braze or silver solder some an warshers on to give a nice large diameter band of contact
having the an just slightly larger od than the end fitting diameter allows a beautiful tiny fillet of brass or silver and will not warp the warsher like a weld
then get you a set of shcs countersinks(piloted counterboring tool) to make the socket head cap screw attachment bolts be flush https://www.mscdirect.com/browse/tnp...yABEgLN5PD_BwE

finally found some time to work on the subframe. finished the last brace. i havent decided whether to do an undertail. if so, ill leave the rails parallel and hang the exhaust between with a cross brace.
Spent yesterday at the track. Beautiful day in the low 80's. Best trackday weather in a long time.
Got my tire wear situation sorted out. Went faster a little. Still slow.
Nothing fell off the bike. And kept it on the rubber.
