When I looked again, after you mentioned it, I did see it was cordless. Eyes are getting a bit old to see quickly and notice things.

Mitre Clamp
I completed this mitre clamp at TAFE today, it was a fun little project and I'm happy with how it turned out.

Terrific idea Jack,
I cut a washer in half and use the cut diameter as a screwdriver then lose it and then cut another washer in half and then every now and then find these stray half washers in odd corners.
That hollow point screwdriver is great - wont easily lose it. Thankyou.

Thanks Bill, but I have to admit it's a copy of the one Mal at Australian Metalworking Hobbyist normally sells. He was out of stock and I'm impatient.

Having a go at a QCTP
Attempting a qctp - based on article in recent Model Engineers Workshop.
A bit messy, will learn as much as I can on this one, and and then do it again, hopefully better.
- Hacksaw made a better cut than bandsaw on the diagonal slit - however it can get a bit tedious and tiring on the arms.
Have gathered several plans for different varieties of qctp - after messing around with the dovetail today I reckon the easiest version is the fat round post with the drilled out rectangular toolholders. Google "Norman QCTP" and you will see a heap like this ....

Not too different from what came with the 9" Hercus - maybe the easiest of all is just to make a few more toolholders for the original Hercus toolpost ?
Anyway was curious enough to have a go and bought an el cheapo dovetail cutter to cut the mild steel.

Chuffed - QCTP works fine
Got the qctp up and running today.
............... and as an added bonus I finally got a decent finish from a round nose hss finishing tool - dont know why but that has eluded me for 3 years - I generally use a shear tool or a knife tool turned around to almost rub along the workpiece.
Next job - figure out a workflow to efficiently cut a few more toolholders, and see if I can grind a hss flycutter to rough out the dovetails.
Have seen posts of people using their boring heads as flycutters
See photos 16 to 19 on this page Mini-Maschinen brauchen Mini-Werkzeuge
Alternately is there anywhere I can buy one or two 60 degree inserts instead of a whole packet of 10 for $50ish ? Then I could make one of those very simple "insert flycutters" for dovetails.

Ideally, from what I have read you will need 15 degree clearance angle (TD??) or you might manage with 11 degree (TP??). This is why I have not made one of these yet. I have not been able to find a suitable insert. The clearance angle will depend on the cutter diameter, but the smaller the diameter the greater the angle that is required.

Bill, place your hand on the headstock while the spindle is turning and feel for vibrations. The finish is to a large degree determined by the minute vibrations in the headstock, I place a glass of water on the headstock and watch the wave patterns as a guide . There are RPM's where the vibrations will increase / decrease , something to do with harmonics ! Good Luck

Lots of drilling and tapping on this 20mm thick plate today.

Looks an interesting project, what's it going to be when it's finished?

That is it Kryn, It just makes it easier to clamp the part you want to machine on the rotary table and it leaves a gap below and I don't have to worry about damaging the table.

Thanks for that Trong, a real handy item to have around, certainly saves the R/T. Do you mind if I copy it later.
How did you go with the anchor rollers?

There is no patent on that Kryn. No further progress on the anchor roller since but the bars above is for the anchor coupling, that is to keep the rope stay on the front roller. I will do them all at once.
Regards,
Trong
