Project Checkbook; Chris' Small Project

And some more. i have to break these into individual posts or the server gets pissy.

And again.

I actually ran out of wood (hee-hee) last night, so I'll complete it this evening. I suck at compound curves, which is why the lower supports look a bit dodgy. It is very strong, though, and I think (hope) I can bend the material around it. Again, the back of the seat accepts up to a 4" taillight. I'm using a chrome jubby from a 34 Ford. Let's hope the seat is strong enough.

Chris, I for one, would be interested in an aluminum seat pan. If you are still interested in making them...

Looking great,I like it.

I free hand bent my pan out of an old heavy duty aluminum street sign.
Good thing is it is very strong and stiff,so I only need a rear underneath bracket to attach it to the frame(front to be held with battery strap or lip like a modern seat) as no other reinforcement is needed.

The bad is it's relatively heavy,so I may cut some holes in it and cover/seal the top of the pan with some rubber roofing sheeting I have to keep water/dirt/mud from getting to the underside of my seat foam.
 
I have quite the variety of material available...due to me being wishy-washy about this. The current plan is to make the seating portion out of 16ga 6061-T6 (which is hard). The bent section will be 18ga 6061-T6 and the rearmost section will be 16ga, as will the side skirts. I think there will need to be reenforcement.

The taillight will bolt to the rearmost part of the seat and the front part.

I also have 3/16" 6061 I can use in a bind. We'll see how well the first one comes out.

Steve:

I'll keep you in mind. I'll likely not start building spares until I see how the original performs.

Then, I traced the template onto 18ga 6061-T6 and cut it out, followed by dressing the cuts with the sanded until everything was baby bear. 6061-T6 doesn’t like to bend, so I held it into position whilst my wife drilled 1/8” holes into the ali, then put small wood screws in.

When welding steel, gaps in the material can, at times, be beneficial. Other times, the gaps can be compensated. When welding aluminum, however, the joints need to be very tight. Not all mine are perfect, so I’m a bit anxious of the result.

I have a great sheet metal fabricator that I’ve worked with before, so hopefully he can work with what I give him. If not, I’ll have to redo some portions of this seat. I think (hope) he’ll be fine.

For some reason, the seat looks like it has a dip in it. Looking at it in person (and feeling it) it's fine. I think it is a dirty spot in the aluminum.

Finally, I took the wheels to work with me today. I'm going to have the tires removed so I can clean them up this weekend. Surely, two of these three will clean up OK. My brother can do the ali rim/stainless spokes on his own time. I'm coaching soccer tonight, so no updates--probably until Monday.

I got a lot done over the weekend, but also had a huge setback. If you remember, this project is a gift to my little brother (well, he's 26), and his birthday is in the first part of April. I have a lot to get done this month, and I lose a week for spring holiday.

So I'm basically working my ass off in the garage and it's getting to be less and less fun and more and more like real work. I have a lot of respect for guys who work and in and day out using their hands. It's such a grind. As much as it would be fun to be a professional builder of some sort, I'll stick to my creative marketing/creative media full time gig.

Enough rant. i cannot weld aluminum with my little MIG welder, so I have a sheet metal guy I use for all aluminum welding. While i was there, he offered my a square wave Esab TIG. I've been saving for a while for a TIG, so I find out this week how much he wants for it. He wanted to think about it over the weekend. Hopefully it is a good price.

Here is the seat welded up:

And again. Obviously, the bottom needs to be trued and the welds sanded down. It will then get a good sand and a light polish. It came out much stronger than I estimated and much lighter too! It probably weighs 1.5lbs, so about as light as the DropBars seat I used to have.

Then, I got everything ready for powdercoat. It's all in my car to be dropped off during my lunch. Not pictured is the frame and tank. I sanded on the tank a bit to clean up some of the crap Italian welds. Hopefully, the alumicoat covers the rest of the imprefections.

Now, the really f-cked up bad news. I needed to clean the wheels off, so I took them to a local car wash. It worked, sorta. Then I tried some EZ-Off oven clear. It works great on anadized aluminum and even some of the pitted chrome. I figured, "What the hell?" and left it on for a few hours. Wrong decision. The wheels now look like a big piece of ozidized shit.

Here it is with the very vile EZ-Off.

So I did what any normal, frustrated man does in this situation: I drilled vent holes in the front brake. These are 3/4" and I really should have used 1". I don't have a 1" bit, so 3/4" it is. Something to note when drill big holes (Shit, I feel a rant coming on here)...

Use a reasonably-powered drill. When I old drill died a few months ago, I snuck a huge 1/2" 9amp Hitachi drill home. I threw it in with a bunch of other supplies when we updated our kitchen. (Note: I paid for this; I snuck it in the basket from my wife). Anyway, it is too powerful and loves to twist wrists to shreds when it grabs a workpiece--not so much steel, but certainly aluminum. Yes, I drilled up to 3/4" in 1/8" incraments, but the drill still loves break wrists. I hate it.

Rant off.
