The last step before removing all of Ms. Rusty’s paint by bead blasting is to protect threaded and machined areas. I’m choosing to use heat resistant tape and silicone plugs so they can stay in place during the powder coating step, which requires Ms. Rusty to bake in an oven at high temps to cure.
The flat areas are best covered by the heat resistant tape, as shown in the photo below.
One particular area that was tough to cover was the exposed surface in the bobbin area.
To cover this I cut a piece of tape larger than the area to be covered and placed in over the hole.
Then using an Exacto knife, the excess tape is cut away
Plugging holes was relatively easy using the variety of plugs I recently purchased (see previous post). I used the caps to fill in longer holes like the one shown here:
However, some longer holes were an odd size and instead required the use of two plugs. This next photo shows how one plug was the right size in diameter, but wasn’t long enough to completely fill the hole.
So I took two identical plugs and cut them in half so I had two shorter plugs of the same diameter.
For added protection, I covered/plugged several of the interior holes. I’m not sure these will be actually exposed to sand blasting or powder, but I figure it’s better to be safe than sorry.
For those of you interested, here are 12 photos of Ms. Rusty from multiple angles so you can see what holes were plugged and/or covered.
Top on my agenda for tomorrow – blast and coat Ms. Rusty!!
