Coffin Tank - Fini

 Well I hope to get it mounted and filled tomorrow.  To bad the weather has turned for the worst.

Seat, Tank, and Bars

So Sorry it's taken so long.  But my bars and tank are done, and I have few pictures here.  This is my redone seat.  So the seat pan that I have been riding around for almost a year is actually the back up pan. The original as done and it looked so stinking stupid I could not live with it.  I was put in contact with a guy named Randy in Springville at Tumbleweed Leather.  He did a bang up job, just what I wanted in the first place. If you need leather work hit this dude up, he is legit!!

 The Tank here is all welded up.  I was placing the petcock in the spot I needed it.  Interestingly it was more thought provoking than expected.  Depending on the angle I put it at would determined how much I could use as a reserve or not.  I had to actually think well do I want to have a decent reserve or basically none at all.

 So I had welded the tunnel on a piece of flat and then tacked that into the tank.  I used my shops air grinder with a cutting disc to trim it out.  I looking into using Brady's nibbler, but time was of the essence.

 Tunnel freed at last.

 I little extra grind work, and then I went back around all the welds, now from what would of been the inside, and I didn't use any filler.  In industry it would be called a backing run, just welding the back side of the weld.  For some thing that will have to hold fluid this should be a must.

 Give me fuel, Give me fire, Give me a gas cap that is centered and I'll be happy.

Don't ask where my camera has been but this is the tank done, check Brady's facebook photo's of his day in the shop with me. But he'd got some good pics of this tank finished.  This here is the front mounts, I went for the hook under in the front to leverage it down.

 Here is the back mount.  I tell ya having the CNC cutter is awesome for some one off parts.

I use a liner called Red Kote, and I love it.  You can get it in a kit like Tank Kreem if you like.  But I have had no problems with it, but make sure you have great ventilation this stuff will knock you out.

The old tank mounted back on cuz I wanted to break the new bars in around the schools parking lot.  50mph straight aways, no biggie.  I love how the feel, the are so much better than the old ones.  Let me tell you this, all you that make bars out there, more power to you!  I had all the material cut I just needed to cope the uprights and it took me from 9 till 4 to get this set all welded and polished.  I was getting pretty pissed at times, just not lining up, not staying straight, errrr I almost threw them across the shop and said forget it.  Sorry this is the only picture of the bars, I was not in the documenting mood at the time, but I think they look good and they ride Great.  Brady's got the clear coat hook up, so hopefully not too much longer and we are in business.

So here are the pictures I have been promising

Just a little peep show of the TIG

Tunnel is being cut to size

Tank was trimmed an inch and then tunneled

It FITS!

What do you think?

Tank Progress

Well I was able to cut out the panels for my tank, and weld them together.  I have pics on my phone but I'll get them uploaded sometime before never.  I think I have a new idea to use some of this new TIG brazing I picked up to out line the tank and of course my lightning bolt.  But we shall see.

Some Tunnel Action

So how do we take a piece of flat 18 gauge sheet steel, and make it into a tunnel for a new gas tank on a old Honda motorcycle?  A lot of beating, real hard beating!

Flat 18 Ga.

Beat it, strap it down.

Grabbed a plastic hammer from the shop

It started getting hard towards the neck.

The SS zip tie broke so I just got some cheap wire I had lying around and fastened her down

Over all I don't think this turned out bad.

So yeah only took an hour and half to do this.  I had the piece about 5"x24" but that was about 6" to long.  I had no way of cutting it till I found some cold chisels in my tool box.  I struck a line and it broke right in half and now it was 5"x18".  I wish I wouldn't of had to beat the crap out of my back bone, I muffed up that paint something fierce, also you never know what structural damage was caused.  I don't think it affected the integrity of the backbones steel because it was a soft hammer and not metal on metal but you never know.  So now sometime by the end of this week or next I'll cut the tank out, but I would like to ask should I cut out all separate panels and weld them up individually or try and keep as much as possible in flat development and bend it up?

Thanks for looking.

Help Me Decide?

 So I have been trying to get an Idea for what looks best on my bike.  I am doing a coffin tank cuz I don't have fancy wheels and hammers to do curves.  My hard spot is the back bone, I can't decide what looks good with the crap square of a mess tube.  so here are my choices.  Mainly two are really similar and mounted with a shallow tunnel, and the other design will be more deep tunnel.  Either one can be modified, I have it saved in Solidworks and can change depth and length with ease.  So please give me some feedback and suggestions.

Thanks!

Help me choose.  The left one might be stretched 2in. and the right would be shrunk 2in.

Random

I peeped these over at bubble visor, definitely not the norm. I think they are super rad.

Then I saw this chopped Harley tank and thought it was super fantastic.  See more at kemosabe and the lodge 

Flat Development

I thought it would be easiest to weld across that seam than the other way.  Each Half will be bent into shape and then welded together. I just need to make the tunnel.

Oh and "I am Batman"  only because they look like bats.

Gas tank Final

Or at least for now.  What do you think, I actually modified the dimensions to about the size of my current tank.

So these are a few tanks I peeped today on the net.  I really like the far left one.

Gas tanks?

Which one do you think I should go with? or spend most of my time working on for my bike?

Thanks.
