seven years later I wanted to apologize about this post. It is not a stupid design as the rest of the thread eventually showed. I just could...
Riverboy, Geeze, forgot I even posted this. No I haven't put any fins on. It's getting snowmobile season, so it will be next spring before any...
After I posted yesterday, I bought a second hand 6-7/8-inch impeller to try. Right now it's 6-5/8. My '86 Evinrude 48spl is a good runner but I...
tunnel design pics Here's those pics I promised. The aluminum plate the welder used is a little thicker than the original. You can see the air...
Jet tunnel Hey, if anyone on this thread is still interested, I successfully installed a tunnel on my old tin flat-bottom jonboat. I made...
Terry, I thought about experimenting by drilling and tapping some holes in some of my dive weights, and then puling on them, but never got to it....
Dang! Wish I knew that first. Well I'm not done; I have five more to do if I want to sister all the bolts. I can fix those. I guess I can pull the...
Just some more notes I thought of: The bronze(655 everdure) was very tough(impossible) to use a thread die to cut the threads with. We had to...
follow up Here's what finally happened. I ordered 3/4" silicon bronze round stock from Alaskan Copper in Seattle. Nice folks, They cut it to 12"...

Thanks for the reply. I think I highjacked this thread. I was thinking that "correct in ballast placement" covered keeping VCG correct. I...

last post Thanks all for responding to this thread. I am much more informed about this and confident of the outcome now. I will not get to...
I am thinking now perhaps I need to pull a stud to confirm the thread size and if they are machine threads in good shape, then I should just...
Tom, The machines get shut off at happy hour:D wardd, It sounds just like drilling in uhmwpe—that stuff can grab you tool too. I like he...
Thanks again, I bet if Dick Valdes wrote up some notes and self published a book featuring all the old designs he worked on, he could sell one to...

the keel I'm back. I was putting new shocks in the car so I didn't get a chance to look at the thread til now. Wow! some interesting input....
Yea, The thought of making a mechanical connection with something as soft as cheddar cheese is alarming for sure. But it seems that is what the...
recycled shaft I found out today that my machinist buddy has an old 1-1/4" bronze boat shaft that we will probably cut three studs from. We...
