| Subject: | Fitting an un-drilled panel onto blind tabs |
Kolber guys (and girls),
In the spirit of offering helpful tips, as Doug (Dnul) just did, I
offer this hopefully helpful tip to fit a panel onto hidden tabs.
Here's the scenario; Suppose you have to make a custom panel that
fits very tightly in a difficult-to-get-to
place, like say, a floor panel. Once you have cut and trimmed, and
filed, and sanded=85.and you've finally got your panel
that precise shape that fit's like a glove, your mounting points (tabs)
are now hidden, and you no longer have a decent
vantage point to view where the mounting holes should be drilled. What
to do, what to do???
Here's what I came up with;
An un-drilled floor panel that I recently made for my GlaStar was
placed in position. I could see the mounting tabs
beneath the panel from the front of the plane, but no where near
accurate enough to be to place a locating pen mark
on the topside to drill the holes.
So!! I took an old 3/16" bolt, chucked it into my drill, and turned
on my bench grinder. I spun the bolt head against
the grinder creating a pin-pointed top. It sort of looks like a rivet,
but instead of the head being rounded, it came to sharp point.
Then, I lifted up the floor panel, dropped the pointy-headed bolt in
place, re-positioned the floor panel exactly where I wanted
it to be located. Then, I took a small block of wood, roughly centered
it above the first tab, on top of the panel and TAP! Next,
removed the panel, looked for the tiny dent, and then centered punched
it a little better, and drilled it out to 3/16".
After placing the floor panel back into position in the floor, I
dropped in a bolt=85.exactly locating the panel where I wanted
it! But, before I had set it in place, I dropped that pointy-headed
bolt into a tab on the opposite side of the panel. Then TAP!
Voila'!! Second bolt hole dent. Removed panel, center punched second
hole, drilled 3/16", and re-installed.
Once you have two bolt holes drilled, and the 2 locating bolts
inserted through the panel and their corresponding tabs (on opposite
sides of your panel), that sucker is EXACTLY positioned where it needs
to be, and then you just keep on working your way
around the remaining tabs, dropping in that pointy-headed bolt per each
next tab to tap a small locating dent on the panel's underside.
I think my custom-made floor panel had about 8-9 bolts to hold it
secure. Each one of those holes was as exact as they could be.
It was as if I had access to underneath the tabs to drill them.
I think this method offers several variations of uses to allow the
builder to make very precisely located blind panels. Below is a
duplicate
of the bolt I ground down. It needn't be any fancier than a beat up old
bolt, ground down to a sharp point!! BTW, the 1/8" height that it
holds
the panel up is a non-factor.

Variation of Ducati SS's method: Lay two same diameter tubes side by side, take
a steel ruler and lay it on both tubes, drag it along the top of both tubes.
The steel will leave a light scuff mark.

I should get a 3/8" dia aluminum tube 8 and 3/4 inch long to hook the springs to
so they're stretched 1 and 3/4 inches to get to the pedals in neutral since
that is what the plans call for.

To drill the center of a tube use a "V" block. Simply lower the drill on the drill
press down to the bottom of the "V" to position for center.

| Subject: | Re: Latex Pain Forum |
If you already have reached the Poly Spray stage, you've already added all
the weight to the fabric covering that you need, otherwise to save money
why not do as Appendix A of the Poly Fiber manual suggests and go with one
of the three PolyTone colors that have the silver in them and no Poly Spray
is required. You save money and weight.
If you're going to do latex paint, research what the successful
experimenters have come up with. Latex has UV protection built in and will
do the same thing that Poly Spray does.
Using Poly Brush and Poly Spray and then overcoating with Latex is probably
the worst of all worlds in terms of covering weight.
As for doing repairs of Latex coated fabrics, good old commercial Goof Off
will take the latex off to get down to bare cloth.
Some find it hard to believe how much weight can be added with coatings. My
Mk III is 35 to 50 lb. overweight because an auto painter slobbered on so
much AeroThane until the fabric weave was completely filled.
Light Kolbs fly better. The closer you can get to 500 lb. empty weight the
happier you will be with your airplane.

| Subject: | Re: Rudder Spring Length FireFly Question |
Doug, From the picture it looks like either A) the tube that fixes the end
of the springs is too short, or B) the springs are too long. You need to
have the springs in the relaxed length when that rudder pedal is fully
depressed, not when the pedals are equal, i.e. rudder centered.
