Whizzerdude,

I'd have to ask you if flexing is not a problem then use 20- to 16 gauge, if you don't want any flexing go with 10 or 11 gauge. Been awhile since anyone replied with a suggestion so I thought I'd offer my suggestion.

How did your seat pan turn out?

C.H.

Were you naughty or nice last year, did the Holiday Season bring any of you any new Welding goodies?

Big Boy Toy's Wish List:
1. Maybe a new Welder Tig / Mig / Stick

2. Maybe a new Welding Helmut

3. Maybe new welding accessories ie safety gear etc...

Well maybe you'll get a nice Tax Refund and purchase that long sought welder or welding accessories.

Maybe if you don't mind you could share some pic's of your shop and equipment with us.

C.H.

A big thank you to you Crazy Horse! It's been so long since I posted this I forgot that I did. I never did get an answer until now. I'm new to metal working and this really helps. Flexing is my problem.
My first attemp resulted in the seat pan pushing the back fender onto the tire and a 100% lock up at a good speed. The little tabs for the wires under the fender caught up on the tread of the tire and locked it up solid. I never knew I could swivel my hips like that but I didn't go down. I was running WFO at the time so that was a good thing.
I've been watching some YouTube vides on making fiberglass pans but I'm new to that too. I may wind up with the only wooden seat in town. I'm a retired carpenter. lol.
I can't use a conventional bike seat because in my attemp to gat a bobber look for it, I lopped off the top of the seat post on the frame to lower it. You can cut it off but you can't cut it on. Big mistake.

Carpentry skills can be an asset, JMO. Let us know how this turns out when you've finally decided on a metal or wooden or fiberglass designed seat pan. It all sounds very interesting to me.

Will do. I've been painting the fork after welding and have to get the bike back up on it's wheels before I go for a shape for the seat. It's going to be awhile

I say wood is a good way to go for a seat pan. I have seen a few people use a skateboard deck.

I posted a few pictures of a wood frame... A seat should be easy... Lol

OG,
Have you considered making a seat pan frame from something like 3/8" steel round stock then using wood/plywood for the pan. Of course I'm assuming you plan to add foam or something to absorb the road bumps and unholstery. I've made a couple of chopper/bobber seats using this method and they seem to work fine.

2door. I have given something on that order some thought. It's good to know it would work before I start. I still need to get the front end back on the bike. I don't think the paint on the fork is quite dry enough yet. I'm going to start on it next week I hope.
I still have half of a leather jacket from the thrift store left for the upholstery, Jell pads from the knees of a wet suit and foam. It was a mighty rough ride on my first attempt
