FOR SALE - Drew and Alan's sidecar build

[Fast Eddie]

Before or after you ploughed it into the wall at HD...??

snaking under brakes after hit wall at hampers..

noticed it at Wanganui Street race but ignored it and carried on assuming it was because of racing on public roads. But knew it was definitely different at Rnd1 NZ Nats at puna.. home track, knew how it should go and it was just so different. Felt really wierd.

Have done a lot of work on the chair since Nats but haven't taken it out since - hoping its better now.. if not will have to keep looking for damage or something off.

Time to dredge this thread up. We've started work on the chair again.

Yesterday I got the brake masters remounted on the left hand side. Ian wasn't happy with the brake set up as it was, because the push rod wasn't in a straight line which might have caused issues. So the push rod is now a pull rod to sort that out.

We battled with it to try and get enough lever travel, so that if one failed it would bottom out and the other would still work. But the Tiltons have 40mm of piston travel, even if we took the lever ratio down to 4 to one which is too wooden, that equates to just under 160mm of lever travel before the other master even thinks about coming on. (In real terms, it isn't that much because of the bias bar and lever points I know).

So I phoned Mr Staples and asked about putting a stopper on the masters. We discussed it at length, and it will work fine and be safe....But it's kinda moot as he pointed out, since we have the hand operated brake as a fail safe anyway. Meaning to comply with the rules he has set out, there isn't a requirement for the twin master system fail safes on our chair.

Sussed!

So it'll be brakes on the left, gears on the right now.

To the front end.

The single shock is getting the bums rush. I managed to score a pair of GSX1400 shocks for fuck all, and Robert Taylor says they're a decent quality unit. The single shock was cool, but even though we thought it was over engineered it turns out it was not. There were signs of things moving, that we didn't foresee.

The removable top plate on the forks is going, as are the tapered roller bearings. It's better practice to use those than deep groove ball bearings, but it too shows signs of moving in places we couldn't imagine. Seriously, the flex that goes on in the front end of a chair when it's on a track is fucken phenomenal! In the hole in our aluminium top plate for the steering stem, it looks like we tapped a thread into it.

If you don't want to use taper rollers, think about an angular contact bearing for at least the bottom.

Chur.... and you thought I rode 'loose' out of speed and effort...... in reality it was beacuse it's flexing like fuck!!!

Finished the brakes today. And started moving the knee cups.

Where you moving them to? down further? padded seat to you big poof

It's got flames though!!

With moving the brakes to the left, they fouled the knee cup. That one's gone up 10mm, and the right one down 20mm to level them up.

Seat pad was on it when we got it, and saves me crushing my nuts. So it can stay.

Not much danger of that happening they'd be kept in Jody's handbag anyway

I get to borrow them to race.

Been busy these last few days, and progress continues.

This is the front end with one of it's conventional two shocks mounted. By Christ it takes forever to get everything parallel and even when you remove all the mounting points to be replaced!

You might notice that everything is quite industrial in size and strength. Honestly, we just don't want the friggin things bending and flexing anymore. So it's probably a good kilo heavier than the previous version.

how does it work with the bolts in the slot?

We're putting an adjuster on them, similar to chain adjusters on bikes.

Late model stuff just has a rectangular plate you can change with different offsets in it to change the trail, rather than the chain adjuster your'e talking about why not a snail adjuster, be easier and faster to alter

I want the huge range of adjustment at the moment, so we can dial it in and figure out the range actually required.

It's coming along, but I dunno if we'll be ready for Ian to do the inspection on Saturday.

I see a trip to Wanganui in our future.
