The hatch covers get put on today and spreader bar cross bracing cables installed. I may have to shave a little off each end of the airfoil spreader bar to make up for the 1/16 th aluminum pieces at each end. Will have photos when done. Have come up with an idea on how to minimize any water spray thru the air intakes, that may be picked up from the float splashes. Photos to follow.

Re: Aviation Design Turbo Beaver on floats

Didn't get as much done as planed but here is one of the two, cover plates with holes drilled and countersunk for #1 screws to make them a flush mount. Will have to spray the black screws ; silver. Not all screw installed yet.
Also decided that I will bevel the edges around the plate a bit ; to make them more flush looking.

The x-bracing will be done tomorrow as got interrupted by honey-do list; gotta keep them happy ! right ?

Re: Aviation Design Turbo Beaver on floats

Here are the photos of float cross bracing using turnbuckles to tighten . Better than their design to tighten and then try and clip on the clevises.... almost impossible. Click on pics to enlarge.

Re: Aviation Design Turbo Beaver on floats

Here is the fuse hoisted on my electric winch... Works like a hot damn. Slow operation to fine tune winching and gearing holds perfect.. Has reversible switch so full power up or down. Last picture are the floats bolted but not cross rigging wired. The reverse is done to install the wheeled gear. A very easy, one man operation

On to installing the rest of the pulleys, steering system and water rudder retraction system... Geeze, and I though I was almost done.

Re: Aviation Design Turbo Beaver on floats

I think you should adopt me. I'm very handy, and come with my own spouse, she also builds, and we've got an RV, happy to relocate to Kelowna! I'm super jealous, this is indeed a dream project.

Re: Aviation Design Turbo Beaver on floats

Looking good Len.

Will be great to see it fly in the fall at Shuswap Float fly. That will definitely be a "new sound" on the beach.

Cheers,

PaulD

Re: Aviation Design Turbo Beaver on floats

Working on the pulleys and brackets now and attachment points from some pictures sent to me. The supplied pulleys are too large for scale in my opinion so these are about 2/3 rds of those. Then there is the hookup to to lift the water rudders (so I don't have to buy the beer ... Lol).

Yesterday, made up a new charge harness for the A123 batteries that will do a charge and balance thru the battery balance connector . The rate will be much lower than thru the battery +-leads but that's ok .

Re: Aviation Design Turbo Beaver on floats

Didn't get much done today.... got a few more pulleys made today and put some screen over the cowl inlets to break up any water splashing off the floats. Not sure but think that misting will not be as troublesome.
Had a few lookie visitors and that broke up the day .

Re: Aviation Design Turbo Beaver on floats

Have installed the Powerbox evolution , hooked up the receiver and programmed the receiver throttle to the ECU. Looks good.... was hoping to do my first propane start
on the Wren before getting any further.... Due to some club commitments for today ; the start may have to be delayed till tomorrow ; if not then Monday as camping this weekend....Gotta keep the other half happy !.
Will get at least one prop balanced today. Using 2 bladed wood props for wheel operation per recommendation of Wren; in case of any tip over. C/F will be used on water.

Also installed a pair of Dubro 5.5 in. wheels ( thanks to Al S. from Edmonton) that have foam inside and are a much better tire to absorb rough ground running. The original tires had little to no compressibility. They would have been fine for a hard surface. Machined up new axles as well to fit.
The third picture I have replaced the steel 5mm fully threaded bolts with smooth brass and then last bit
threaded for self locking nylock nut. not fully tightened in picture. Did this to minimise any thread wear on the aluminum fittings.

Angus M. ( original owner) did a great job in the original build so just tidying up a few things to the way I like.

Wiring will be bundled and nylon strapped to clean up. More to follow.

Back to float steering work early next week. I can begin to see a little light at the end of the tunnel.
