I'd like to see if there is any people out there that may be interested in either a replacement
or back up rudder cage and mounting brackets.
Due to a recent collision with an uncharted rock I damaged my unit (broke the lower pivot point).
Cost won't be real cheap (I'm estimating about $500.00 ea) but it will be as close to an exact replacement as anyone could get.
If there is enough people interested price would also come down (please don't use the number noted until all the details are in place).
I'll check every few days to see if anyone is interested.
Thanks in advance.

What does the $500 dollars get you? I ripped my rudder cage/scabbord off the back of the boat two summers ago (which destroyed the hinge brackets) and had the old brackets repaired by welding, plus made a new set out of welded 1/4 inch aluminum angle that appear to be tougher than the original for about $125.00.

My 500 "guestimate" is what I see as a worse case price. Figured I would get replies from those that were interested only in a replacement unit instead of those that opt for attempting a repair.
I do understand the cost to repair can be cheaper but considering it's probably one of the most important components on the boat I'm going to do it right. Ours failed in 3-4 ft seas I'm keeping a spare on board too!!
Got too many $$$ invested in my 73 PD to not repair it to original condition. Also can't afford another failure while underway (weld is not as reliable) hence my direction.
If there's no interest I'm going to have 2 assy's made (one backup) and get out of it.
My intent is/was to help out other PD owners that may be in a similar situation.

Give us an idea of how you will design it. Standard size stainless bars and sheetmetal, how joined etc.

Depending on the price I might be interested as well. My scabbard has also been repaired. I talked to a guy who sailed his Dawson to Venezuela and his broke near Cuba. He had a hard time getting it welded properly in Cuba due to fact that it was made out of some sort of unusual alloy. Soes anyone know if this is true and how to affect a repair if needed?

The scabbord is nothing but an aluminum weldment. If it fails, you should be able to weld it back together using the original piece or a replacement piece and have it just as strong as when it was new. However, I would recommend checking it over for cracks as their may be other hidden flaws that exist, but are difficult to see.
Regarding the rudder hinge brackets, if you are worried about the aluminum being strong enough, it would be very easy to make a set out of cold steel and then keep them painted to prevent rust. You could even put a bronze bushing in them for the rudder pin. If you wanted to go the Heavy Duty expensive route, you could have them machined out of a block of stainless steel and I think this would cost in the neighborhood of $500.00. The factory aluminum brackets lasted 22 years though so I think that is all I need. LL

I had a new cage made in stainless, rather than the casting originally used. This has been satisfactory. But if I had it to do again, I would use some sort of tip-up design rather than the slide-up design. cdherz44@yahoo.com |

Yes - it is called 'Aluminum' and is probably an exotic alloy on Cuba LOL. There are only a few Communist countries left ... perhaps soon Wal-Mart and our beloved Govt. will be finished building the Chinese economy and military. Then maybe they will help Cuba for a while and Cuban welders will have access to TIG technology. Seriously, any competent (US-Based?) welding shop should be able to deal with this. I will try to get photos of the reinforcements the local welder made to mine (which is now 32 years old). -Tom |

First time since I've been back on the site in a while (sorry)
It appears there are 2 people other than myself interested. Based on that I'll look into it in more detail. For the others, sorry if I've stirred up a hornet's nest (not my intent).
This proposition is clearly not for all on this site. Repairs to some are considered adequate and that is fine. I personally prefer a new replacement part that is fully heat treated and matches the OE part both physically and structurally.
For those interested:
The part I'm looking to do will be the same as the original (unpainted)and with oil-lite bushings at the pivot points (cage only).
I'm planning to canabalize my cage to create the new parts and then
the finished part. Everything will be heat treated like the original too. I hope this defines a bit clearer what I'm planning.
I'll post cost specifics once they become available.
Thanks.

To those interested the material is a sand casting aluminum alloy.
It appears to be either a 356 or 356A grade. Key once again is it's post heat treated adding considerable wear and strength.
Welding casting grade alloys can be done with TIG (and an experienced welder of course).

The final step would be Clear Anodize, I assume ??

I was out sailing this weekend and saw this rudder scabbard that looked very simple and might work for a Dawson. It was from a Beneteau 24.  Download Attachment: 10-06-07_1444.jpg8.41 KB |
