RE: rudders

Sandcasting is low tech , a local prop shop should be able to create a plug, cast it , then machine it to fit.

RE: rudders

If you have a rudder they can use that to make the mold, or you can make one out of plywood. It is not expensive to have something cast.

RE: rudders

I wonder if it's something that can be made on one of those slick new 3D printers.

RE: rudders

OK. We have a machine like in our engineering dept that but it is not called that.

Very expensive compared to making one from plywood or clay.

1st make a 3d CAD drawing.

2nd find somplace that has*a machine and one large enough for the job (ours would be too small to make a rudder).

Pay for the service. (I will find out what ours costs to run someting as large as a rudder and advise.)

Thanks for your comment.* I wish we had one to use for a mold.** A boat mechanic said he could get something close, and machine it to fit, but* it would be expensive.

( or photograph and dimension one to make a plywood model?)

RE: rudders

No problem, but it will take me a few days to get to the shop in MD to access the parts. Might put your request on the Californian forum & see if anyone has a 34 on the hard & could help out faster.

RE: rudders

I had given up hope: still no rudder solution.* If you can provide a photo and dimensions it would be very helpful.* Grateful for whatever.* Thanks.

RE: rudders

LOOK on the californian forum.* There was a discussion about rudders and sizes on a 34LRC.* You don't mention what model Californian you have.* In the rudder thread it was pretty obvious that some variation exists in rudders between model years and even within the same model year.* My boat is on the hard right now.* I believe by memory mine are 14" high x 10" wide.* I can check that on Wednesday when I'm working on the boat, if you like.* My rudders are somewhat rectangular, others are more rounded.* I have a picture of mine but unfortunately they are in the camera in the boat and not on my computer.* I bring it back Wednesday evening as well.*

Before you spend to have something custom made, look here:* http://www.deepblueyachtsupply.com/m...ering-hardware

I have had no experience yet with these people, but will have by the end of the week if they ship my cuttlass bearings and zincs I ordered this morning from them.

My rudders*are very close or identical to the spade shape model 10r20SS1.2

Others Californian ownershave what* looks like the standard* shape.

I don't know what my shaft size is but you should have the stuffing boxes to measure.

There is a lot of latitude in rudder designs that will work.*

RE: rudders

Ordered some shaft collars for my ongoing rudder issues from Deep Blue Yacht supply; prompt shipment; good quality items. Will most likely order from them again

RE: rudders

not rocket science...you don't have to have the exact same rudder as before.* Any rudder that has the same shaft length and diameter and approximate area will work...especially if lower than full planing speed (less than 20 knots or so).* The other consideration is if it has a lower bearing or is balanced...if not just get something close.*

Here's a US supplier that almost any marina store can order from...
