I'm not much on the tech side so I just reply separately. You can copy and paste parts from different posts and if you want to show it's a quote you can type in a left bracket sign then the word QUOTE and then the right bracket sign, paste the text you copied, and then type in the left bracket sign again, then the / mark, then the word QUOTE again followed by the right bracket sign. You'll have to add the members name when you do that if you are quoting different members. It doesn't automatically add it as the system does when you use the Reply with Quote function. Sometimes I when I want to break up a long post and reply to individual parts I'll use that quote trick. For example -
Quote:
Chuck, you are a moderator, am I replying to all my replies individually?
. I copied and pasted that from your post.

When I want to set a circ saw so that it just cuts through something I just set it down on the material and lower it until it bottoms out on what I'm supporting with.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Copy & paste is clunky on ipad, and I got so many replies, in fact many came in while I was trying to reply.
Through cuts are easy, it's the less than through cuts. I hope to finish and post pix in a few days.

Dale: If you want to quote more than one person, first hit the "multi-quote" option on all the people you want to quote, but on the last one, simply hit the "quote" option. This will put all the quotes into one reply.

Lightbulb You need a Guide Wedge

Find a piece of scrap which is
w) roughly the same width as (the distance between the edge of the plate of your circular saw and the blade), say 5 inches,
l) 24 inches long (the distance between the first and last slot) and
t) 2 1/2 inches thick (the difference between the minimum and maximum depth cut).

Now taper this down (along its length) so that the width and length remain the same, but the thickness reduces from 2 1/2 inches (on one 5 inch edge) to zero (on the other 5 inch end).
On the 5 inch by 24 inch face, draw 24 gauge lines, 1 inch apart, parallel to the 5 inch edge. The guide wedge is now complete and ready for use.

Set the depth of cut on the CS to the maximum slot depth and make the first cut. Check the depth of the slot and adjust if necessary. Leave the depth at this setting for the remaining cuts.

Before lining up the CS for the second slot, put the guide wedge on top of the workpiece, slightly to the left of the second slot (so you don't cut through the guide block), long edge parallel with the direction of cut, thin end nearest you, with the first gauge line aligned with the edge of workpiece. Cut the second slot. It will be 1/16 inch shallower than the first cut.

Move the guide wedge towards you, so that the second gauge line is aligned with the front of the workpiece and move it just to the left of the third slot, then cut the third slot.

Rinse and repeat.

The more cuts you make, the thicker the wedge at the front of the workpiece and so the shallower the cut.

At some point, the part sticking out over the edge of the workpiece will be heavier than the part still on top of the workpiece, and it will be ready to overbalance, so just spin it round 180 degrees and start pushing it back in again - be sure to mark which slot you are on before you start this move.

Basically, it just a taper which lifts the base of the CS by 1/16 inch for every 1 inch it is inserted.

Each cut will be very, very slightly shallower at the back than at the front, but we are probably only talking a few thou.

To change the increment to 1/8, either mark only 12 guide lines 2 inches apart, or mark all 24 but only use the even-numbered guide lines.

This is just theoretical. I haven't built one before, but I think that its should work. If you try this out, please let me know the outcome.

When my time comes, I want to die like my grandfather did - quietly, and in his sleep - not kicking and screaming like the passengers in his car.

Thanks, David, at first reading I can't say as I understand it, but I did print it, and
will study it. I think I saw something like it, but it was very expensive, and only a
limited number were being produced, and the increments were way to coarse.
I am working on a bigger project so I am just making cuts as the need arises, but
it is working great. Every half inch will be 1/16 deeper. In just 3 cuts I found the
saw had to be raised 1/64 ? By the time this is done I will need a new blade!

If it's working for you, Dale, that's all that matters.
It's not so much that a circ. saw isn't accurate once set, it's more like the adjustment mechanics are pretty crude and never really designed for making minute depth corrections.
If you come up with a quick accurate solution, let us know!

I start by setting up as you outlined, then making a test cut. Those test cuts were always 1/64 too deep. Finding
1/64 shim was a problem, but I found the plastic box the Veritas edge marker was right on! Sudden idea, I could
cut a set of blocks 1/64 oversize, naw, too clunky! I shall perservere.
Dale.

A lot of guys use old playing cards as shims. Measure one and just do multiples.

In the enhanced mobile view (as seen on my iPhone) each post has a check box in the top right corner (see thumbnail pics at the bottom of this post). Touch that box to make a check mark appear. Then you will see some options appear above that. Touch the quotation sign (shown circled in red in one of my pics). This allows you to quote a post and reply to it. You can check off multiple boxes in several replies and then tap the quotations and be replying to all of them at once. I believe you know what to do from there. After you get as far as I described it’s just a normal post from there forward.
