well i stripped it again, put it back together couldnt see anything wrong, it spins freely then when i put the layshaft in it gets realy realy tight when a gear is selected, also i guess the selecter forkes are hard to move by hand, i had a screw driver through the rod and pulled and pushed and realy yanked to get the syncro hubs to engage and disengage, im not sure if the tightness is from the new bulkrings or something else, if its the bulkrings how do i remidy it? whats the best way to check the gearbox function while its on the bench, i dont want to put it on the motor and then in the car if theres something wrong

This is not uncommon with new baulkrings, usually it's the 3rd gear baulk as this is being 'squashed' while the gearbox has not been torqued up, but the best practice is to find the 'skinniest' baulkring for 3rd.

Once the box is torqued up put the unit into reverse gear, and you should be able to turn the input gear anticlockwise by hand. If you can't it's too tight and you may need to change a baulkring, either for a different new one or a good used one, this will be the 3rd baulkring.

Just got to this stage of my gearbox build. Your guides are excellent! As predicted there is this tightness/binding of 3rd/4th baulk rings (a new set). How is it that the baulks are being 'squashed', but torquing up will eliminate this?

When you build the gearset into the box the third and first motion shafts are pushed together when tapping in the bearings. Once you torque the box these two shafts are then pulled apart, thus increasing the gap between the third gear and the synchro hub and more room for the baulkring.

 

Best check to see if a box will turn, put it into reverse and turn the input gear anti-clockwise.

 

Pleased you found the guides useful.

is your layshaft true?  A while ago i thought i heard of some off centre ones getting about.... grab and release type motion.. ?

This is prior to the layshaft being in. So it definitely sounds like torquing up is going to solve it.
