Re: homemade outboard

One must work at ones own pace, so dont feel preusured to complete on my or anyone elses account ;p

Personaly, I would use a hacksaw to cut the bolts down to size, then a fine tooth file to smooth it all up pretty like. You can also taper the end of the bolt a little wile cleaning it up with the file, wont hurt anything, and is easy with a large margin for error.

About the flat nut on the round ABS thing. It shouldnt look too bad, I think you will have to resort to RTV silicone or something similure for a seal. If you are really concerned with a flush meeting of nut to abs there you can always cut yourself some custom spacers flat on top for the nut, and slightly curved on bottom for the ABS out of wood or some other available materiel.

On to the taping of the shaft.. Small typo here, that should be TAP not tape hehehe.. I am not sure of the diamerters you are dealing with. But what I was trying to say was If the shaft is suficiently larger then the hole on your prop. You might be able to drill the shaft and tap it out to recieve your bolt through the prop into the shaft. One drawback to using this method, You will not be able to lock the bolt in place, you will be relying solely on 1 bolt without a cotter pin. a locking washer or 2 might help.. it is possible to drill through the shaft & bolt and put a cotter pin in behind the prop but still through the shaft and bolt if this method is employed, But this is not a recomended way, Just an alternate way. Something that would work if it had too. ( if the shaft is big enough. In my experience, as long as you have 1/16th of a inch sidewall after taping, you will be alright, if it is less, the sidewall might giveway under load ). Personly I think reducing the shaft diamerter and using s dye on it is the best method, it allows for you to be able to lock the prop on with a pin. Hmmmm... It occures to me here that you can always tap the hole smaller then the prop hole if need be, and use spacers on the bolt build it up to the prop hole thickness. but as stated, this is not the best way, Just A way. If I have failed to decribe this good enough I can knock you a picture together

I was just sitting here thinking I feel just like my old shop teacher here, He used to present several ways to do something but let us decide which was to be used.

Sidenote here. buddy of mine, also adept in making adatchments. ( no typo there) an Adatchment is a term we coined a few years ago wile creating animitronics for a haunted house. An Adatchment is a part, usualy an handmade custom adapter that connects 2 or more things that dont go together, In order to make them do what You want them too, reguardless of what the parts were originaly designed for.
Anyway, after discusing this prodject with him a few different times as we have progressed here, He is now looking at making a Jet water drive for his rubber raft. That should be a challenge. weight is a real issue in a rubber raft. Im thinking weed eater here as a powerplant, but I am still undecided. Either that or a chain saw. but thats another story. If he persues it this summer Ill start a new thread for its discusion.

-ever forward
