I thought I'd better do this as a new post instead of putting it with the guy version of a seat lift. They'd probably toss it right out!
Here's what I ended up doing cause the hardware store did not have any urethane 1/4" washers. They only carried faucet washers and the thickest one was 1/8 on an inch at $1.29 each. You can calculate how much that would have cost me, not to mention making the holes bigger on 24 washers, seeing they only had a small puka in them. They didn't even have 24 of them.
Here is what I did:
I cut 2 1 1/4 inch dowel pieces (1 1/16 width), drilled a 1/2 inch wide puka about 1/2 inch deep (for the rubber thingies underneath tank bracket) and 1/4 all the way through for the bolt.
Then I glued the washers on them.
Then I had some chrome looking metal tape very stiff and hard to handle and wrapped it around the wood a few times for looks and support. And then of course I did the girly thing of adding some 3mm rhinestones in cobalt blue fabric paint on the top and bottom edge.
E voila! my version of a seat lift!
I also put a little strip of rubber underneath the rubber cushions. Oh boy!! what a difference in height! good thing I have long legs!
Now I'm wondering if my turns are going to feel different with the seat being higher. I'd better go slow first.
