You'll save yourself a lot a sanding and filling problems now - if your sand them smooth now before gluing.
Look close at the picture.
Nearest the side of the sanding block you can see the right side of the ring edge is smooth and square.
When the rings are cut, they are rough and "wedge" shaped. the outside is a little narrower than the inside.
This picture better illustrates what I'm referring to.
The ring on the left is rough, the ring on the right has been sanded flat and square.
After sanding with 220 grit, seal and harden up the surface with some medium CA applied with a Q-tip.
Sand this down with 400 grit.
The sanded CA surface will be like glass.
Neatening up these exposed centering rings is a challenge in the Custom "Ion Pulsar" kit as well. But they look so nice!
ReplyDeleteHi Ray,
ReplyDeleteI've been sanding the rings square like this for a few years now. I knew if I glued the rings to the body tube first, the larger BT-55 tube would never line up!
