Drag racing seat

Agricultural that seat may be, but it works. Good to see that another is trialing it also.

Thanks Rob I would have liked to have stayed to try to back it up but not possible. Left on a high note and F.I.G.J.A.M.ed to a few bike savy boys at work,much to their disgust no doubt.

Well, progress update. prevailed upon a mate who has a workshop with a lathe and mill, so now have prototype brackets made and hopefully a prototype seat done tomorrow.
Brackets look OK. Used the original set screws, which hold a bar, and the seat fits onto the bar at the front and the key lock at the back. Zackery the same as a hump or back seat fitting, but full length. Made the jig to fit the back bracket and I'll do the front when I get a trail seat. I'll post photoos. So far cost around the $700 for parts, mould and a carton of TED (for the lathe and mill work). Bit of welding tomorrow at the ship builders and hopefully a trial run soon.

cheers for keeping us posted Bear mate, I'm just glad that hump is being put to such good use.







dont forget to tell me when you've got a few ready ok

Actually the hump is looking a bit sad. When they made the mould the resin reacted and the hump got stuck in there. It can out OK, but needs a total repaint.
I will wait till I get a hump to paint and then do the lot.
The trial seat is due out early next week, and I've now mabnufactured all the bits needed for fixtures.
The trial seat will be used to sort out where any reinforcing etc might be needed so will probably not get around to painting till it's finalised.
I'm determined to use it at the bike day in Feb though!
So far the costs, except for the mould, are low. We'll see what he wants to knock out a "production" seat!

[BEAR]

Well, mould looks good and they popped out a trial seat for me yesterday.

Heres the difference in the seats, one a standard seat with cut foam, the other "the seat".


Back brackets are a duplicate of the original design but in aluminium, so key works just the same.

The bar in the picture is shown fitted at the front where the original seat bolts fitted. Irt's just a 10mm bar threaded each end and necked down where the tank hinges.

Looks a bit flimsy but the seat is supported at the extreme ends , so no bending. Just need to cut slots in these to replicate the nylon parts of the original seat (at the back)

Now I have to resin all the bits together and have a trial fit. Clean edges and bingo.
So fitting will require the normal allen ky for the seat, then re-use those screws to fix the bar in. Then slide the seat on to the bar and push down like the normal hump does at the back.

Ooops, used the photo of the original plug, here's the seat fitted.

Mate that's some great work you have done there. The thing

looks nice and low. How many will you have to sell to cover

the set up cost

It would look cool painted in your body colour

Keep the up dates coming Regards Richard

So far it's cost me about $700, but I have to work with the glasser now on the final design. The prototype is probably way too well done and could be a bit lighter and cheaper. So when he gives me a cost I can work out a sale price. I can do the brackets for nothing but some costs I'm stuck with.
Hope to get it pretty well siorted late next week.
Cheers
