I have done my homework. I have issues aligning the guide bush it keeps shifting around 0.5 or 1mm. I have placed extra nut on each bolt to lock them together, but don't have much fate in it. Have you had experience with this issue? I can keep using one side where it is correct, but seems a bit dumb.. Should I just cut off the extra from the treads, because it leaves a big gap at the back. I will cut a sample riser tomorrow and mark the rebate for the treads. Should I route out now the rebate for each tread? The router bit I am using is 120.00 thick I know we agreed on 90.00, but what if I use the bit I already have? This shouldn't change anything just the thickness. The riser How to do the little lip? I could set up my small router table up in the snow No really, how do I cut it?
