First, let’s test it out. Ideally we’d like to use it, so we’re making plates with different offsets to check the dimensions. (Both ended up in the trash.)
Having a shearing machine and punch press is really handy for times like this. <\/p>\n\n\n\n

Once you know the dimensions, the rest goes quickly.
I always want people to remember that the first one is always the hardest. <\/p>\n\n\n\n

I would have preferred to finish it with spot welding, but it wouldn’t fit, so I docked it together with TIG welding.
<\/p>\n\n\n\n

<\/p>\n\n\n\n

Four completed! (‘\u03c9’)\u30ce Wait, not two? Or six?
Two would sit really poorly,
and six would stick out too much, so we went with four. <\/p>\n\n\n\n

The owner also wanted the rear reservoir tank to be bolted down.
There’s no threaded hole to pull from, and most of it is painted anyway…
So we went with a piggyback strategy using the offset bracket we made earlier.

Round bar is the most versatile\u2014best choice ever! (‘\u03c9’)\u30ce <\/p>\n\n\n\n

It looks like it’s sticking out, but it’s actually sitting snugly in the sidecover, so don’t worry. <\/p>\n\n\n\n

We made it from SUS304 stainless steel, 2mm thick, so it’s pretty solid and secure.
The bolt head sticks out about one head’s worth. <\/p>\n\n\n\n

Is this good enough? All done! (‘\u03c9’)\u30ce
