Stinkeys trike ?

[stinkey]

Cheers dude..sometimes I sense your getting despondent with your pop build mate ? Keep at it..you can always take time away and carry on another day.?

[Manky Monkey]

Yeah, gets that way sometimes. 

[stinkey]

Managed to spend a bit of time and mocked up the M/C bracket..had to buy a new reel of welding wire and got some gas too..roll on tomorrow ..

[Plasticpig]

looking good.

[stinkey]

Cheers mr pig..glad you like..in an ideal world I wouldn't have the throttle and brake M/C where they are ? But I have to make this rideable for both the Mrs and myself..

[stinkey]

After spending a couple of hours attempting to chop some wood..I managed to mock up the brake pedal..will need to get the correct size bushes and the correct pushrod for this landrover M/C ?

That's a big master cylinder. Couldn't you use a smaller Girling one like a lot of us have used on Reliant trikes, & mount it the other way round, tucked between the footboard & frame, with a drop arm below the pedal to push backwards into the cylinder?

I have the small Girling mounted forwards but rear mounting and adding a bellcrank allows easy pedal ratio adjustment.
Are you running dual circuit brakes ?
You may want to rethink that pedal ratio. Aim for about 6:1.

Hi guys after using a smaller master cylinder on martins trike..which to be honest was crap..I thought let's try doing a split system using a land rover M/C..I must admit I was surprised at the size of it ? ( ooh er missus ! )..so one line to the front and other to the back..so trying to keep it simple..and I thought I'm bound to get a response to this..he.he..it's only mocked up and tacked..so I'm open to good suggestions and ideas ?

no room inside the frame Andy ..I'm trying to keep everything up high as poss..springers do like to bounce sometimes..and I may yet have to fit a front shock or extra springs ? But all suggestions humbly accepted 

[Olds]

Have you thought of mounting the master cylinder beside the gearbox or prop, with a rod and crank linkage ? Should be room inside the frame there and the reservoir would be protected from being knocked.

[stinkey]

To be honest I can't be bothered to start running linkages and bell cranks etc..I just want to keep it simple ( like me ) iv got the radius arms from the rear wishbones to chassis to fit yet and the electric box will be fitted under the prop shaft,so not much room there ? It is only mocked up..so plenty of fiddling to do yet guys..and at least it helps fill out this side of the trike compared to the other side ?
I'm sure it will all change by end of the week ? And I am listening to your ideas guys..muchas grasias...6-1 ratio ? 

[stinkey]

And I also have to account for her ladyships smaller feet..compared to my clodhoppers ?

[Olds]

6-1 ratio ? 

Pedal ratio = leverage
Ratio of the difference in distance from the pivot point to the foot pad and the point where the master cylinder push rod attaches.
The greater this difference is, the greater the force acting on the master cylinder for a set amount of pedal pressure.
At a 6:1 ratio a 60 lb force on the pedal equals a 360 lb push on the master cylinder (6 x 60 = 360)
Think 6:1 should be thought of as a minimum. Not sure about your particular application, as I believe the master cylinder may be one normally used with servo brakes and I am unsure as to it bore.

I popped into see how martins doing with his trike today..shame about the chequer plate..
