Elevator VG's - Curved Skin Leading Edge!

A new tool had to be made to put a bend/curve in the VG to match the curved leading edge profile of the elevator.

Add about 3/16"(setback) to the cut profile of the block... you can see the cut line on the block. The Block must be the same shape as the VG forming block... but 1/8" is added to the width. To form the block 2 pieces of 3/4" plywood are glued together to form one piece...

Sand the upper and lower mating surfaces and apply a coat of alcohol and 5 min epoxy mixed together to get a hard surface...

The lower block is glued to the square 3/4" base and then sandwiched between 2 blocks for support...

November 28, 2009
Note that the lower block MUST be 1/8" wider then the upper block due to the width of the Vg in bent form. The upper block is then made narrower by the width of the VG forming block. Should be about 1/8" narrower, trim until it matches the formed VG part...

There it is... a simple tool that works very well...

Formed VG in place in the tool... ready to be bent. A 2x3 about 6" long can be used with a 2 lb hammer to bend the Vg. DO NOT hammer the upper block directly with the hammer, use the 2x3 it works great...

A closer look at the bent VG Part, it looks pretty good. Compare to Zenith's VG Part in the next photo...

Zenith VG Part...
Compare the VG Part just made, to this VG Part... it is the one that Zenith is selling for a pretty hefty price...

VG making tools, can't get any simpler...

VG Part Patterns needed, you can use your own dimensions, but 60mm x 30mm x 35mm and 15mm high seem to work ok...

Wagner HVLP Control Spray Plus - Spray Gun

Here is a new tool for the tool box - my new Wagner HVLP Paint Spayer System. Great Spray Gun - can be used with all kinds of paint such as Waterborne Epoxy Primers, and Waterborne Polyurethane etc. There are some very nice but pretty expensive systems out there... this system was to good to pass up! It's a self-contained unit - no compressor needed!

Paid $79US from Gleem Paints. Runs off of 110V and feather light. Princess Auto had one that I was able to take a close look at... for $130 from China and it just could not compare to the quality of the Wagner HVLP system. I had a Wagner electric spray gun back in the 80's and it was one super unit but a little on the heavy side... this unit is 100% better and weights only 7.8lb for the total system! Once you get to using it and get it setup properly for the paint you are using... it is basically set for good, very consistent and no further adjustments! A huge benefit with the HVLP is there is hardly any overspray... which is wasted paint(high volume and low pressure), and with the price of some paints now a days... WOW!

Wagner HVLP - Control Spray Plus... paint sprayer system. NO compressor needed... has powerful single stage turbine control strong enough to spray interior Latex, Stains, Varnish, Enamels, Lacquers, Shellacs, and both water based and oil based! Has 3 spray patterns - horizontal, vertical and round! It has variable air pressure flow control and single stage turbine that can spray interior latex yet reduces overspray. Comes with a 20' hose, Lok-n-Go spray gun, 110V, 1 quart metal cup and a 1.5 quart plastic cup - weight of the whole system is only 7.8 lb

 

New Much Needed Tool: - 5' Bending Brake!

Built out of wood... 5' in length this much needed Bending brake will be well used for all of the 701 shorter parts fabrication, except the 8' parts for the Stabilizer and Elevator, Wing Rear Channel etc... Will build an 8' Brake when needed for those parts!

5' Bending Brake showing side view of the 5 clamps... 8 - "C" clamps are the best to use! This Bending Brake cost less then $50 and simple to make... all though I started building it 2 years ago! Other then that an 8' foot is needed for the rest of the 8' parts!

Front view of the new 5' Bending Brake... sitting on a 4' table! Started out with a 6' brake... but it was too long for this purpose and I did not need one that long for the shorter parts!

Rear view showing the 1" slots in the bending bed for the 8" - "C" clamps... Note also that the bending bed is 1+1/2" above the table mounted on a 2 x 6 - 10" long at each end... and 4 - 2 x 4 - 10" on 12" centers at each door hinge location! There are 6 - 3"(square) Stanley Steel Door Hinges mounted with 2+1/2" wood screws.

View of the top Radius Board - 1/8" radius and 45 degree slope... can make 45 degree bends no problem!

Another view of the bottom of the top Radius board... note the duct tape the full length. There is also a strip on the bed... why the duct tape? Simple... it holds the aluminum from slipping between the boards and... keeps the long parts from developing a - Banana shape!

End view of the top Radius board... 45 degree shape and 1/8" radius!
