This video shows revision 1 of the bike seat mod but also lots of clips with tips of aluminum welding tips using Tig.
A good friend of mine goes to a spin bike class and now wants her Trek bike to feel like the spin bike she uses at the gym.
That meant modifying her seat post and adding some gussets...but I agreed to give it a go and that video posted a couple of weeks ago.
This is Rev 1 and I hope its done because I have lots of bigger projects on the horizon. ( like a big steel tubing lifting fixture that is a good job for pulse spray mig)
Why doesnt she just get a new bike?
Shes is a small girl and just cant get the bike to feel right which most likely means she has the wrong size bike frame. She likes the way the spin bike at the gym fits her and that is what she wants out of her Trek bike.
She is happy with the way the bike feels now.
A lot of folks who knew something about bikes emailed and warned me that this was a bad idea and that she just needed a new bike.. but she has had the bike for 20 years, she is not likely to sell it and get a new one.
Something about the position of the knee related to the pedals...etc.
But the spin bike she uses has about 10 inches of adjustment on seat travel and she likes the way it feels.
I figured... what is the worst that can happen? It doesnt work and we buy a new seat post and start back at zero? no problem.
Anyway, revision 1 didn't make for much of a video so to make it more interesting, I added lots of other clips from previous videos showing some slow pulse at 0.7pps, and some lap joints, and butt joint tips.

This excercise will keep that filler rod hand busy.
