pardon me for asking.... just what are we looking at? Is that a hull? :shock:

Or maybe it's the plug for a mold you are making?

thanks for posting the photos dblj. :)

how the heck

Postby Randy Jr » Sun Feb 24, 2008 3:09 am

how the heck do you guys do that every time... when i cant post someone else can...

and It's a cheap wood/glass hull made after the lake buggy plans for people that can afford expinsive airboats and its filled with foam so if i bust it somehow it wont sink and i wont loose my motor/prop ect...

If i recall correctly maybe $100 on wood/glue/screws
Got lucky eought to get a kawa 25hp for free
and all my metal i have scraps just laying around im useing
but i hav to admit the prop kicked my ass at $470 witch i know is cheap for a prop im just a broke ass :-P

so minus labor i prob got... 800 bucks in it? and all i have left to buy pullys for the belt drive


Thanks for posting the pictres by the way dude greatly apreciated.. i finished welding up my prop mount this afternoon out of some old rusty scrap metal we have laying around now i have to sand blast it sometime this week and paint i up with a rattle can..

I see it now. It's thin plywood with furring strips on top of it.
at first glance, it looked like the hull was made out of a bunch of 2x12's and it looked on the heavy side.

I see it now. plywood webbing. Lightweight. Nice.

There is a thread around here someplace about how to post photos.
There is a definite trick to it - simple, but it's a computer - so no typos allowed.
Maybe it's in 'site related'.

good luck!

Back in the old days, wood boats were a common thing.

I got to ask how much does it weigh?

oh man

Postby Randy Jr » Sun Feb 24, 2008 10:59 am

oh man i dont remember i forget the weight in the plans but when i get it totally completed ima drive it to the truck stop or the race track and get a weight on it... with 2 people i can pick it up and put it off and on the trailer so i figure if i take four guys with me when i weigh it i can just weight it and trailer pick it up an sit it to the side then weigh te trailer alone and get an exact weight on the boat... i'm realistic i dont even expect it to run fast at all im thinkin 10mph but where i fish it couldn't be a mile from our boat ramp... we just have alot of shallows i cant get threw to get to the good catfish holes cause the water go's down to like 2-6 inches and the ol jon boat and the outboard just cant hanle it

I've seen talk on here that the old timers would run a sheet of stainless steel on their hull bottoms, like poly is used for today.
It would obviously add to your weight, but would add A LOT of durability to add something even as thin as 28ga.
Even 28ga in SS it is extremely tough (and rigid) stuff !!
5 x 12 is a standard sheet dimension.

Just a thought in case you find that you get too much wear on the bottom.

ill keep that in mind

Postby Randy Jr » Sun Feb 24, 2008 12:00 pm

ill keep that in mind i'll tell u what i wish i did was instead of the plywood bottem just used a thick poly as the bottem just in place of the wood would have been a good bottem and i could have left that wood weight out but.. u saw my budget above :P hard to buy poly for that lol

I told you the pictures where easy :lol: nice to see you found your way back to the site

3600 rpm engine and 3100 rpm prop you need a 1.2:1 ratio ( some thing like a 3.25" bottom pulley and a 4" top )

Wood is extremely light and strong when it's used to it's full potential. Don't forget that one of the largest airplanes ever built was made
out of wood ...... the Spruce Goose.

Chesapeake Light Craft ( CLC-boats.com ) has a 17' 9" Wherry rowboat in their catalog that weighs 65 pounds!

hey dude long time no see yeah old computer crashed and i forgot website and passwords and junk but im back now... just got home bout to goto sleep so i wont be tired at work tonight but ima put a couple more pictures up real quick... thanks for the ratio i think i might have messed up getting a composite prop.. the wooden one would have been lower rpms and i could have used a better reduction What do you think??
here's a few pictures one is just me and my girl friend and the others are my prop stand...

ya I want to know that answer to :lol:


Randy ,
the composite props are always better because there less maintenance and hold up better plus they are adjustable etc etc the 3100 rpm figure they give you is the MAX but it will start pushing below that number except war drive witch need to stay up in higher RPMs. I assumed you have a two blade ordered but multiple blades would give you push at much lower rpm thus you would need a big ratio reduction to swing them . I would suggest that you look at Cog belt pulleys instead on V belt pulleys witch at some point you will have slippage problems withe the V belts IMHO. You could maybe push your ratio up to maybe as high as 1.5 and adjust more pitch in the prop also

prop

Postby Randy Jr » Mon Feb 25, 2008 9:39 pm

i ordered it from arrow prop it a three blade prop made for low hp engines like the kawa 25.. its adjustable but it comes with pitch blocks so i would imagie if i wanted to adjust it i would have to order some more sets of pitch blocks i dont know for sure but when i ordered the prop they asked me what reduction i would be running it on and i told them 1.69 x1 just becaue they told me last year that is the reduction i would need to put on a wooden prop so i assumed i would be the same for the same length compostie then i read on their site that the composit opps at 3100 rpms so i dunno what im gona do... and i was gona do like a 3 V belt pullys i dont know how easy it will be for me to find cog pullys around here especialy at a price i can aford :P " my buddyslooking for a belt for his harley right now $200 just for the belt" i dont wanta get into something like that for a 800$ boat :-P if u know what i mean i just might have to accept some slipping im gone to work guys talk to you later :P

While in general belts are proabably better, have you thought about motorcycle/dirt bike/ATV chain & sprockets?
The Harley belt drive & pullys would be great, maby a used set off flea-bay or a MC swap meet?
I would really like to know what the hull weighs, looks heavy duty!
