Guide rail alingement

[petiegolfer]

I have been watching everything to do with this with great interest and have one method in the pipeline.

It uses:

-the incra 52" bar
-3/4" incra tracks and sliders in a MFT1080
-it uses the squareing useing the "hole principal"
-it uses the garanteed cut to blade edge system ie the Domino one...but can be tailored for a new blade perfectly in seconds
-it is good for 1080 sized material an will be perfect for small rips

It will be sorted in initial form at the weekend and I should have the camera up an running again for pics

Have another idea as well but it is top secret!

Ok everybody is waking up, good morning

Top secret idea isn't really....

The theory is parallel motion:

-Corwins jig did it yesterday.
-Imagine a big drawing board...the guide rail being the // motion bar.
-the saw obviously runs up and down the bar
-work piece is squared on a fence similar to the 1/4inch idea by Qwas?
-the guide rail is squared off that
-measuring can be taken care of with one of Johnes sticks

Methods for // motion...
-pulleys and wires..moving parts etc but very simple
-mitre sliders in 3/4 track...will it stay square over 5foot?
-will have to sort out methods of attaching guide rail
-do you have the sliders flush with the bench surface and then the guide rail locates on them with a height adjuster.
-could the mitre tracks help with something else...

Expansion of the idea...
-if the direction of motion is along the 8ft axis of a board you can cut across the 4foot axis
-how do you cut along the 8ft axis....you create a jig which slides up and down the guide rail and the saw mounts on it on a short piece of guide rail ie saw length piece
-are you still with me...the saw mounts to cut along the 8ft length...ie perpendicular to the guide rail
-if the guide rail slides in tracks then the 4ft axis will be accurate the jig can be moved up an down it to rip over the 8ft length.

I don't know if this is too complicated and to much hassle to sort out for a full 8 ft sheet...I don't have the time or the space to do at the moment..for anyone wanting to have a full sized table it may be worth the effort.

I have the bits off an old drawing board and will try to dummy something up on my MFT. There is even a portable method which may just be worth a go at thinking about it some more.

Let me know what you guys think any way.

I'm also finishing an improved version of the fence I described elsewhere (MFT guide rail alignement thread).
also using Incra tracks (only the 36" one, because a 52" would cost me 170 USD since not readilty available
in France). It seems to offer the same features as those described here, plus a few other goodies more
related with work organization .... secret, secret, secret 

Will describe it later when I'm finished with a table restoration job and my MFT is picture friendly.

I just brought a 52 and it cost me ?60....$120? For what Im doing I only need the one.

My system will give full table width ability and perfect repitition. Its initially going to be made out of mdf but I will get a buddy to machine up some metal components at some stage.

Look forward to see your ideas...I really like the buzzz of everyone imagineering!

I have 4 - 52" laying around, maybe I will play with the idea a bit.

This sounds like an interesting project. Looking forward to some pics

Piers. where did you buy this 52" track in the UK ?

There 170 USD is about USD 60 for the track and USD 110 for shipment from the US,
and this does not account for VAT and import taxes which would add USD 20.
It might be cheaper to ship it from the UK !

I got mine from here

I get components for golf clubs from the US...my buddy there sends me things that have been "Recalibrated" or "fixed under warranty"...

If you know what I mean
