RE: How did you spend Sat. 03-17-12?
I spent that weekend in Portland and managed to run down to the Evergreen Air Museum in McMinville, OR. The Hughes H-4 Hercules AKA "The Spruce Goose" is one big bird. Lots of nice planes there..

RE: Getting kids involved in model aviation
Who says kids don't want to build.. My daughter has been a great helper and is interested in learning to fly. [img]http://images.rcuniverse.com/forum/upfiles/196377/Wu62210.jpg[/img] I think she's old enough now to learn without getting frustrated and quitting.. Any time I get the balsa box out she pops up asking to build a glider.. I think it really has allot to do with the kid.. some just don't have the interest to stick with it like my oldest step son.. He was never all that much into it and I think just went along to make me happy. Now my youngest son I have no doubts about.. He's 5 and has already declared that my Dirty Birdy is HIS plane and and wants to keep my T-rex in his room..

I didn't manage to get the glass and carbon down into the mounting lugs. The are mostly resin and air bubbles.. I put it in the mounting plate and managed to shear the small lugs off without much effort.. I may do a couple hub only layups to work out a method of filling these in..

RE: DIY propeller?
First test layup is in the bag.. Back half of the prop.. It took longer than I thought.. the resin was starting to kick just as I got the last piece of glass down.. I wasted a bit of time because I didn't have the tow pre cut.. everything else was cut and ready to roll. I'll remember that next time.. I'll do the front half tomorrow.

RE: DIY propeller?
Progress so far.. I finished the glass, made a foam board box last night and packed in 3/4 lb of sand mixed with 120g of resin. I topped that with a piece of 4oz and went to bed.. This morning I put on 3 more layers of 4oz and left it to cure. [img]http://www.pontiacs.org/pics/projects/byronp51/IMGP2337.JPG[/img] Now all I need to do is not touch it for 24 hours... easier said then done. I'm itchin to pull the parting board off.

RE: DIY propeller?
I'm going with pink foam as the material for the parting board so I setup a quick vertical foam cutter using my workmate, a fiberglass kite rod, car charger and some 33g wire.. works great. I decided the best way to make a template of the parting line from the prop was to cut out a foam copy and use a pair of dividers to scribe the parting line over to it.. I then traced paper templates and transferred them to the outer shells. then I cut along the parting line template with the hot wire.. I glued the foam to a sheet of 1/2 MDF, bolted the prop down and sanded to fit the parting line. I'll cover it in packing tape, wax it, bolt int he prop, use clay or cabosil & epoxy to fill in the little gaps and smooth it over.. Then add some hot glue registration dots and get on with the tooling coat. Comments and tips are always welcome..

RE: DIY propeller?
[quote]ORIGINAL: SCALECRAFT Make sure that the hub is solid enough to tighten without distortion. Also use continuous composites that tie the blade together from tip to hub.. Avoid small pieces of composite. Steve [/quote] No problem there. The shop did large projects. All the pieces I have are 4-5 square feet or larger... The 3k I have is a 40' roll of 4" wide plain weave. Some pieces of 12k twill were folded so I'll use some of it in the molds.. The current plan is to make a hollow mold prop.. Each half will be 3 layers of 3/4 oz glass. 3k plain weave carbon full length, 12k twill carbon full length then more layers of 12k progressively shorter back to the hub until the hub is solid.. 1 layer of 4oz glass, peel ply, blotting and then into the vac bag.. I may add in a few loops of Kevlar tow to hold it together in case of a prop strike. after the cure they will be joined using epoxy thickened with 404 and clamped together. The first piece I pull with be just glass and used to make a cuffed plug like the prop in the attached picture.

RE: DIY propeller?
OK all supplies on hand to make molds.. time to get started.. I have 1/2 gallon of 635 Cabosil West 404 West 423 graphite blue dye Partall #2 wax Partall #10 PVA Assorted weights of glass down to 3/4 oz. loads of 3k and 12k carbon acquired through a friend who works in a composite shop. (off cuts and end rolls) Just to throw a wrench in my plans I have surgery this Tuesday.. We'll see how fast I recover and get working on the molds. Anyone see an issue with using 12k carbon in the molds? I have a lot of off cuts that were stored folded so it's not in perfect shape.

RE: DIY propeller?
I ordered a 1/2 gallon of 635, some 4 oz e-glass, partall wax, pva, cabosil and some other stuff to make the molds.. I'll try a few layups with the 635 and see if I need to switch to west for the layups. I might make the first one just glass so I can make it a plug for a cuffed version. While I wait for that to arrive I'll get started on the parting board.
