Topic tags/keywords: circular saw base plate parallel zero clearance

I have an older Porter Cable circular saw that has always treated me well. Unfortunately I can’t say the same how I’ve treated her over the years. I’ve dropped her so many times that I shouldn’t be aloud around her any more. The base is no longer flat or square, nor does it run true with a straight edge (no longer parallel.) Do you think that I can make a new base plate for it? Any thoughts if so on where to start? I really haven’t seen too much about people making a new base for the CS, lots of cross cutting and ripping jigs though.

Thanks.

I see I didn’t much traction on this but I’ve had some time to think on it and this is what I’ve come with:

The idea is to use one of the DIY zero clearance jigs for a circular saw. If I were to undercut the fence on the jig to allow for the base to slide under the fence and add a hardwood fence to the saw … I could fix one end of the saw fence and allow for adjustment on the other end. Then I would be able to get the edge of the base (read as new fence) parallel to blade.

I’ve managed to get the edge of the base and blade parallel by shimming, but it’s only good for one depth, Max. And the shimming is not that great—definitely not a permanent solution by far but it’s getting me by at the moment.

Hey Chunk, did you do that drawing in AutoCAD? It looks good.

Yes to AutoCAD. Even though I’m an Electrical Engineer, I used AutoCAD like others might use a calculator. I always layout everything in AutoCAD first. It’s the best way of finding interferences. Lately, I’ve been drawing everything in 3D. I just layout a set of drawers for my garage workbench and I did the entire drawing in 3D including the finger joints for the drawers. Now if I just had the lumber to finish the construction…

The drafters at work all use Inventor. For me, AutoCAD is all that I need. I don’t need to do a lot of stuff in 3D for work and I’m at that age now where I’m not investing a lot of time to learn yet another “latest and greatest” software package.

Garage Workbench w/ New Drawers
This is the sort of stuff that I use AutoCAD for. pretty basic stuff, but it does tell me if the piece I have designed will fit or not.

I’ll make you a promise. If I can find a PC that has Inventor on it, I’ll give a try but there ain’t no way I’m shelling out the cash to purchase my own copy of Inventor when I already have my own copy of AutoCAD.
