Prop shafts, Rudders

[JordieS]

Hello everyone,

I have searched around on the forums a bit but can't find really what I want to know about Prop shafts.

Where do you people get your drive shafts, skegs and rudders?

Does anyone have any info on making the drive shaft hole and installing the shaft, seals etc? I have looked on Glen-L (the best so far) but would like to know more.

Thank you everyone again

As for purchasing stern gear I dont know your market , best to surf Goggle or Boatdesign net for many sources.

NSW Sydney,

Also I'd just like to learn bits about all the parts involved in an inboard setup and how they all come together

Thanks

Google Professional boat builder magazine. A while back they had some articles on shafting and alignment.

I use a flash light on the drive shaft plate coupling. It shines a light on the hull were a shaft would go. Any discrepencies in the flash lights accuracy can be avaraged by slowly turning the coupling.

A lot of boats I have been involved with during builds have used gear from P&W Marine - Brisbane. They will build to a design you supply (as I have done in the past) and have a lot of patterns available for skegs etc. Expensive, but are pretty reliable.

Depending on your application (you didn't tell us), I'm guessing that you could be looking at a simple tube with a pss seal or similar attached.

The application would be for a wooden or glass ski boat (not sure).

Thank you everyone your input is appreciated

I doubt p&w will be interested in a small job, they weren't for mine.
Instead I went to like http://www.marinecastings.com.au/

Wouldnt you position the shaft where it is supposed to go and then build around your fiberglass shaft?, at least, that's what I did while the hulls were upside down and easier to work on.

These blokes http://www.kmrolco.com/Kincaid_Marine_Rolco.html are the manufactures/suppliers of all the bits you will need running gear wise to build a boat in OZ. I have dealt with them and they are excellent. They have a downloadable comprehensive price list of parts on the link supplied above (yes their prices are available and upfront).

There is a reseller of skegs/shafts/propellers in north west Sydney that you may come across, I would not P on them if they were on fire!!!!!

I ended up making my own shaft from 431SS from interlloy in minto (Sydney) http://www.interlloy.com.au/our-prod...ainless-steel/ , this way I could make exactly what I wanted for less than half the price of a lesser grade shaft.

For "V" drive and the fff fast gear Argo manufacture and sell http://www.argorace.com.au/index.cfm?menukey=129

How hard was it to make your own shaft?

There is Porters in Parramata Sydney suppose to be the bees kness and did mine wihout any trouble --I think it is Porters, turn right after Mc donalds down the road with the chart and book shop on the corner.

I have access to a full machine shop and the standards for SAE and Morse prop shaft tapers/keyways/threads are available on the net.

I spoke with porters, but it would have been expensive and there was a wait!

Just looked for morse and sae shaft end dimensions, think there may have been a link through this site!

Glen-l sell most of the parts your looking for http://www.boatdesigns.com/Inboard-H...epartments/35/ the shipping was a bit much for me in Ireland so I made all my parts to get the angle of the shaft I built a jig of the hull and keeping the engine at the centre of gravity I was able to work out what angle strut to get the distance of the prop to the rudder and prop to the hull.







All worked out well

The best place is the Public library, I know it's old hat, there is so much in books that have been printed years ago and nothing has changed much in regards to prop shaft drilling, instal and various options for seals....
Also sigh up to 'Proboat" dot com, here there is heaps of info, search.
I'm an older boat builder that reads books as much as online 'print' Thing is, a book you can take with you for reading anytime and especially taking to the local merchant or engineer to chat over your own requirements and or options...
