Lumpy
What is Lumpy's rudder made out of????
Sanding had very litle effect on it.
Had to use a grinder!
It looks like that rock hard, gray epoxy!
Once I had flattend the port side, I found that it still came no where near to having the ruddered centered on the screw. (Prop for you non naval types) Found out the the rudder post hole is on an angle.
Pressed the rudder post tube out of the hull and filled the hole with a dowl rod and wood filler.
Will re-drill the rudder post hole with the drill press, and make sure that it is centererd on the screw. then re-install the rudder post tube. That should solve my turning problem.

Re: Lumpy
The rudder very well might be made out of gray epoxy putty... William is very fond of the stuff and it wouldn't surprise me if Mike used it too.
Wood filler usually does not hold up well to water. You might want to consider using something else... Once you get the rudder post where you want it you might also want to reinforce that whole area. There are starting to get to be a lot of cracks, holes, etc. around there. It might be a good use for epoxy putty.
Re: Lumpy
Thanks, Will Do.
Re: Lumpy
OK, I have some 1/4 dowl rod on hand.
I will use the drill press and a 1/4 drill to remove the old post, then use "Gorrilla Glue" to hold the new 1/4 dowl in place.
Once it sets, I will use the drill press again to make a new hole for the rudder post, centered on the rudder. (Of course using a drill the same size as the old brass rudder post.)
I will also beef up the brace for the rudder stop.
Then drill a new hole for the stop so that it will not crack the wood when inserted.
Re: Lumpy
I'm having trouble getting a picture... So the rudder post will be a wood dowel with a brass tube down the middle? Is that right?
Is it going to be easy to hold the boat strait and steady to drill through it? Would it be easier to drill the parts outside of the boat and then square them up while the epoxy is setting up around them? (I honestly don't know) I have a hard time imagining how I would hold any of my boats steady under a drill press... Lumpy is pretty small though...
Re: Lumpy
Yes, that is correct.
I had glassed the non penetrable bottom of Lumpy's hull. So she can take some firm handling there.
I shall drill the center of the dowel outside of the hull.
Then press it into place after I have drilled the dowel sized hole in Lumpy’s stern, centered on the screw.
Re: Lumpy
Sounds good! You should take some pictures when you are done
Re: Lumpy
UGH! Change of plans;
The Barkada will be here over the weekend so I will have to put Lumpy's repair on the side and clean up the basement.
There will be a BIG fight (Manny Pacquiao), and they all want to watch it on my television for some reason.
Re: Lumpy
<joking> At this rate I'm going to have Nassau's cannons done before you get Lumpy's rudder back in! </joking>
It will be great if you and Mary can bring the old Lumpster to the Maker Faire at the end of April. Its a great little ship and I think your perspective as a relatively new skipper will be great for people to hear.
Re: Lumpy
My Sweet Mary is working this weekend.
That should give me a chance to work on Lumpy's rudder.
Re: Lumpy
Got the drill press out.
And have been working on a jig to hold Lumpy so that the drill will be perfectly vertical.
Will post photos soon.
Re: Lumpy
How soon?
Good luck with the repairs - it will be good to see the lumpster on the water again
Re: Lumpy
Not as soon as I would like.
We are hosting a Mother's day dinner in May, and I have been tasked with creating the invitation cards, RSVP cards, and the graphics for the program and envelops.
I have just finished up with what I hope are the last changes to the invitation and RSVP cards. One the design is approved, I shall start putting them in production.
I hope to have a chance to work on Lumpy tomorrrow.
Re: Lumpy
It looks like the operation was a success!
I will be reassembling Lumpy's rudder as soon as the glue drys.
I did take a number of photos, but it looks like I have forgotten how to post them.
As soon as I get it figured out, I will post them with the full story.
Re: Lumpy
Congrats! You should post a new article with the pictures too!
Re: Lumpy
OPS!
Looks like I need to work with this web site more.
I did post 15 photos, but they are in the Ship directory under the heading of Lumpy.
I see that they are not in order!
Re: Lumpy
I see that the photos are in reverse order for the operation on Lumpy's rudder post.
I plan to put her back together this week so that I can do a test sail in the local pond next weekend.
Re: Lumpy
IIRC the photo galleries show the most recent pictures first...
Re: Lumpy
Polished the rudder axel, gave it a coat of grease and inserted it into the rudder post.
Next, I will drill a new hole for the rudder stop, and put in a screw instead of hammering a nail that could split that beam.
Re: Lumpy
What is this "rudder stop"? If you are talking about what I think you are talking about, why not use a collar with a setscrew?
Re: Lumpy
What I am calling a rudder stop, is a phyical barrier that prevents the rudder from contacting the screw. IE limit the range of rudder movement left and right.
Lumpy had a nail was hammered into the brace above the keel to limit the range of the rudder. It had split the wood of the brace. Nails tend to split wood, where as a drilled hole with a screw does not.
Re: Lumpy
Lumpy continues to look better and better - Mike would be proud of what you have accomplished!
Drew: a mechanical stop to limit the range of travel for the rudder. Its nice to have a mechanical one in case your radio settings get messed up.
Re: Lumpy
I plan to give the rudder a new coat of paint this weekend.
I also hope to get her in the water to see how well she can turn now.
Re: Lumpy
How did it go?
Re: Lumpy
The "Honey Do" list trumped any progress with Lumpy.
Shooting for next weekend.
Re: Lumpy
Had some time to work on Lumpy today.
Gave the rudder s light coat of pain.
I have the screw soaking in paint thinner. I am removing all of the old paint from it before I re-install it.
Still need to pick up some boot tape.
I still wish that foam came in rods as well as sheets.
I hope to have Lumpy operational tomorrow.
Just s little concerned that I may have made the rudder too thin....
Re: Lumpy
OUCH! oh wait... you said light coat... ouch
Re: Lumpy
LMAF. . .
As my mind ties BDSM into working with Lumpy!
I have really been "Whipping" her into shape.
I've really tightened the "Screw" on her.
I've clamped her in a "Vice".
Etc.
Once I regained my composure, I realized that I had I missed a "T".
Re: Lumpy
Just learned that is was a good thing that I cleaned the paint from Lumpy's screw.
It turns out that the paint was all that was holding two of the blades in place!!!!
Thus Lumpy will not be returning to active status today.
Re: Lumpy
I was about to break out the torch and solder he blades back on when I thought that I should ask if there is anything special I should be aware of when the brass blades back on, or is it just straight and simple brass soldering?
Re: Lumpy
Should be as 'simple' as soldering large brass parts together. What will you use for a torch?
Re: Lumpy
Just picked up a "Mini" torch over the weekend.
I found my lead free solder, now just as soon as I can find my flux, I will try it out.
Re: Lumpy
Putting the blades back on the hub was easier said than done.
It seemed like just as soon as I was place one blade on the others would fall off!
In the end, I attached all four at the same time!
Placed a rubber band around the parameter to hold the blades in place while I applied the heat to the hub.
Re: Lumpy
Gave the motor controller a coat of "Hard as nails". I plan to do it the reciever to night.
I know, this should have been done a long time ago!
UGH! My thumb slipped when I was moving the MOG around in her transpot box and put a nice large crack in the hull! Feel that I should have her ready to sail unarmed. Too bad that none of the recievers worked with the JR Transmitter.
Re: Lumpy
Is that the 4channel JR radio I gave Mark Bunting? If so, that's a 72mhz radio and would require either a universal receiver or one with positive shift.

Re: Lumpy
Yes it is.
My local Hobby shop spent a month trying to mate it to a reciever.
We went through several recievers, most of them were JR brand.
Purchased JR brand crystals, but could never get an operational rig!
Next purchased a spectrum Tr and Rx.
The JR is now collecting dust.
I suspect that thr Tr might be faulty.

Spektrum really has revolutionized the RC world. FM/PPM is ancient history to me.
