Talking of blades , I've been trying to cut about 25 feet ( 48 x 4inch lengths out of 9 inch rounds of scrap ) 30 mm thick Delrin on the bench saw this afternoon . Aim was to do three or four as prototypes this afternoon and settle on what worked best .Got another blade to try on the mitre saw. The 24 tooth one supplied with it gives more tear-out on the back edge than I want, so ordered a 40 tooth Sabrecut blade to try. I've been quite impressed with the quality of any other type of blade I've had of theirs. Runs true, nice cut etc. Can't fault it. An added bonus is, (with this being a 210mm blade rather than a 216mm, as came with the saw), the laser guide is actually on the cut line now. It was out by a mm or two before. This is the one I ordered.

It's green.
I'm making the inserts to fit in the square rungs of a ladder racking system I'm using for Alison's Bonsai staging display . center drilling one end and slitting the drilled end back a couple of inches in a + pair of cuts so when I run an 8 mm dia decking screw in the slots it expands the plug and allows me to fix a front lip on the ladder rack ends fronts & rears to stop plants getting blown off them at a couple of hundred of £'s damage a pop , includes the hand made special ceramic pots as well as the plant .
I could have cut it quicker with a used wooden lollipop stick I'm sure ..it was slow and hard going , ( not what I expected on a reasonably new rip blade ) with me slowly feeding it in .
I stopped the saw , got a magnifying glass & had a look at the grind and set ... hmmmm ...interesting ...... several of the brazed in teeth are in the wrong sequence of cut . either they've been installed incorrectly or they have been Chinese ground , there is little or no set on the teeth and the set that is viewable is LLLL R, LLRRl, etc , there's no set sequence to them , not just in one area of the blade but over the whole circumference . I aquired a couple of spare new unused blades a few days ago for it , so tomorrow if they look better I'll change it out.
Had to press on with the bad blade as I'm cleaning things up in the lathe's four jaw chuck for a precise fit as well as using the router bench to put radius on the edges on all four long edges .
