Three Dee Thread

[Lorenzo]

Let's go back to the lateral stand rubber;
a liquid silicone H.T. rubber + the colouring dye ( silicone comes in the Brown colour) Is not justifiable at the moment, so for now a (three) Viton high temp o-ring will do nicely, tank you.

This Is the general idea IMG_20231202_233547.jpg

And this Is It, for now IMG_20231202_204401.jpg

For folks with Honda CB1100F and CX650 Turbo, a guy at CB1100F.net is making the, can not be found, trip meter reset knobs. Making them from alum., exact size, shape, color, uses same mounting screw. The OEM's were plastic and I think within the past 40 yrs. all, including NOS, have crumbled and fallen apart.

That's exactly the principale, replicate parta no longer available.

And this Is another approach; using this technology to make the mould for the final part:

From this short video, you can glean a better view:

And for the enthusiastics, this is a preview of the printing head path; I could keep watching for ages...

[Lorenzo]

Must confess this part, despite looking relatively simple, it's going the upward steepy way, but we're almost there...

While printing

It seems we eventually got there !

the airbox face being curved and with differing angles, made It a Little daunting;

[Lorenzo]

printing done;
you can see, in the left side of this pic, a sort of wedge, the slicing software add, as it sees fit, as a strategy of making possible to print in overhangs. IMG_20240401_231456.jpg

from the side, it can be appreciated the fitting of the edge, very adherent to the box contour:

All of the criss-cross patterned area (the support) will have to be removed and the surface refined.

[Lorenzo]

It's Amazing how, by changing the side in which the object Is printed, we can control the exterior outcome of the print itself. In this case, the support material, tedious to remove, will be on the back, so not visibile, thus requiring less finissage. IMG_20240404_174214.jpg
