My Micro Hydro

[JimClark]

I think it might be easier to just shape the foam and glue it in so the sponson will be solid foam. But we will see if it is too hard to shape frames it will be

ah, understood

[Sneasle]

Lookie what came in the mail today :)

[Sneasle]

and a few more...

[JimClark]

How many boats you building. I hope to have frame templates done this weekend.

I've got hulls for 6

2 mini partiots
2 turbine hydros
1 shovel
1 scat cat tunnel

Will probably build a few hydromites in the near future as well since short kits are available.

[JimClark]

It is a whole Micro race team

[Sneasle]

Yup. I've got 6 hulls and 4 radio's total. I plan on running them all on my MX-3s, but come 4th of july at the lake, assuming nice weather, I plan on having a nice race set up for the family.


I got my Epoxy and Marble dust filler in today as well.. now I just need to get my electronics ordered and the plywood so I can get these hulls moving.

[JimClark]

Marble dust?

[Sneasle]

Ya, it's a type of filler for epoxy resins. Haven't used it before but it was very cheap. 3lbs of filler material for $5.50, but shipping bumped the price some.. thankfully I ordered it with the epoxy so it made shipping more bearable.

[JimClark]

Ok in addition to starting to work on the frames I decided I wanted to trim the overlapping flange as much as possible on the sides as I need the space to put the graphics and I think it will look much better. There was one problem in that the top contacted the bottom in only two places just behind the sponsons and at the transom along the after plane of the hull. So I decdided to add some 1/32nd plywood to the after plane sides that were shaped so I would now have full contact with the top and would allow me to add a nice glue surface to the plywood. Only problem is I need to add more plastic or plywood so ship it out flush with the afterplane sides. Shouldn't be a problem and it should look just like it is all one piece when I am done.

Jim I noticed that in the mold and added more material in that spot and raised the top of the bottom mold behind the turn fin. Sorry I did not catch it sooner.

[JimClark]

Randy what do you think of using a 062 wiredrive for the shaft of the micro.

I have been trying to build my test boat to make sure the strut does not need to be too deep for a wire drive. Every time I just about get a kit done for me the good fortune of a customer coming threw the door and wanting a hardware set. On the old micro hydro the strut was not that deep and a wire drive would work fine. This boat the sponson's are a little deeper about 1/8 of an inch. It is a real short shaft and you do not want too much bend in it. To be safe use a flex shaft.

[JimClark]

Kind of what I thought I was just trying to do it with materials I already had.

Thanks Randy
