Going to have a go at making a fiberglass seat!!

bluesmoke69 · « **Reply #26 on:** December 31, 2010, 10:25:13 PM »

Need to sand down to make it more even. Then I am going to coat it with something and sand again.

Used foam from Menards. Cut foam with table saw and hack saw blade. I made a few errors, but with supper 77 and more foam its all good.

looking good, making your own will give you much more satisfaction and be unique to your scoot.

I've heard guys use an electric carving knife to cut the foam too. And maybe a belt sander to shape it??

Good luck.

Thanks guys working going to school and married does not leave a lot of wrenching time. Not to mention -7 below wind chill, and no heat in garage. Trying to find something to lay on foam to sand and shape it more. I was thinking of drywall mud.

hmmm? dry wall mud is something I haven't tried yet..

Bike looks good and i really like the colour - any chance of bigger pics? - my eyesight's not what it used to be .

Yes I have to work on the pictures. I have a Mac and having a hard time with photo conversions.

Get a free acct at photobucket.com, upload to it, then copy and paste. Very simple.

Thanks for the bucket tips.

Was looking at my seat I am try to make and it sucks!! I thought to myself I need some foam with tighter grain. Then it pop into my head 2 part foam from the model store would work well. I then thought if I made a wood frame and filled it I could get my shape I want close perfect. So I was checking out seat threads and bam I found this thread wood cafe seat video. Thanks for the information, and the links. Hope to have some good work done by the weekend. To dam cold in the garage with no heat in the frozen tundra. LOL

I like the color you picked, I'm going with tangerine twist (bright orange) with black trim on my F1.

Question, what did it take to install the Comstar wheels and dual front brakes? I bought a set of the original Comstars for my F1 this Fall that came off of a '79 CB750F, won't get started on installing them until it starts getting warmer.

Just wondered how much work I may have gotten myself into.

It should be to bad. My comstar wheels were from 1981 CB750F. I also used a set for F2, or F3 forks in my triple trees. I had to shim the brakes on the front with some small SS washer, but no big problem. The rear was the same size as mine just bolt it in. Hope this helps you!!

Holubs · « **Reply #40 on:** January 06, 2011, 05:21:55 AM »

That does help, thanks. I haven't found a different set of forks yet, but the guy included all of the brake calipers from the '79 CB750F with the wheels, so I have those.

Some guys like the GL front ends. I like the looks of the 77-78 F front forks.

Holubs · « **Reply #42 on:** January 07, 2011, 10:35:09 AM »

I am not familiar with the GL forks, will have to get a look at a set of those.

I have 3 sets of F1 forks now for 2 bikes, I wonder if there is a way to mount the back side mount dual calipers on the front side of my original forks with the Comstar wheels?

I just caught the tread.

Great lookin' bike.

When building my custom seat, I built up the back with spray foam (window/door insulation) on the factory seat pan. There is virtually no smell, but it took a two days to fully dry. I used a bread knife to rough cut, then used rough grit sand paper to get a better shape. Once I was happy with the design, I covered it with Gorilla Tape. I left about 1/4" of metal on the bottom lip of the seat exposed for the fiberglass matting to grip well. After rough sanding the glass, I coated the fiberglass with body filler. Smoothed, primed, and covered.

Thanks for the information hope to get some more small things done. Maybe were can go for a ride this summer.

Trying to work out design for seat without cutting fender or fender brace.

bluesmoke69 · « **Reply #46 on:** January 09, 2011, 11:25:02 AM »

Thing did go that well this weekend, to cold to work in the garage. It's going to be hard to get the shape I want with the wood, because of the fender and storage hump. I am now thinking of getting another seat pan and doing some metal work.

noahspop · « **Reply #47 on:** January 10, 2011, 02:53:30 PM »

Did those dual calipers come with the bike? I have a F2, and it only has single.
I'm looking foward to the progression of your build.
Thanks for putting the pics in photo bucket.

bluesmoke69 · « **Reply #48 on:** January 10, 2011, 07:51:07 PM »

My F1 came with only one, but the front hub had holes in both side to run duals if you wanted to. The current wheels are from a 1981 CB750F. Hope this helps.

Pretty happy I told a friend of mine about my bike. He said that he has a kawasaki 750 triple, and cb360, and CB200 sitting in the weeds. He said just come get them in the spring when the snow is gone. For free!!!
