Friday lunch prattle

[Bushmiller]

Sounds like I missed a great session.

Did someone record it and put it on youtube?

Doug

I think Youtube may be too sensible. Facebook may be more appropriate bu I am reliably advised you need a phone for that.

Following on from our chat, when you have a log that is a little difficult to manhandle to the saw table, this is a solution:

Not quite as big but an interesting mill nevertheless.

In that case maybe I had better not turn up - you might never finish a project again if you take my advice

I will see what happens on the day. If the traffic on the ring road is better than last week I will make it.

I wont be there again as I am going fishing. Might try to do it with a phone from the beach.

[Simplicity]

I will hopefully be there,
If i learn as much as I did last Friday, I would nearly consider it sacrilege to not attend.

Cheers Matt.

C U 2morrow. (Practising my phone speak for the day when I get a phone.)

No fishing, too windy and wet. So you will have my company, sorry.

My solution to Simon's puzzle.

Black is the fence
Blue is the blade
Red is the stock

Set blade to correct angle and fence to correct width to cut through at centre line of stock or a bit less. Will work with any polygon, calculate your own angles
Cut one corner off, flip and repeat cut.
Straighten blade, move fence to cut of the desired thickness of moulding.
Repeat as required. The wide stock allows safe cuts to be made and hands well away from spinning things with teeth.

My practical test of Doug's solution, angles set around 30 deg, 16mm MDF.
I didn't get the blade fully centered on the angle cuts and ripped the 90 deg a little wider than I planned

This offcut when if fell off, fell over and just caught the front of the blade but didn't go flying... a ZCI would make it safer I suspect

Phil,I think it is best to cut a little short of the centre on the first two cuts. Cutting short will leave a small flat on the end between the angled cut which is a good thing for a couple of reasons.

Firstly, a flat area will allow for the corner you are filling not to be quite perfect.
Secondly, it would allow you to flip the board over and cut the two angles on the other side without adjusting the fence or the blade. Then you would have two identical moldings ready to rip cut off the sides.

Yes, I would be using a ZCI if I did it on the tablesaw but I would probably do it on my 21 inch bandsaw as it cuts pretty clean.

My apologies for not making it today!

I lost the morning due too rain, an spent the afternoon catching up.

Cheers Matt.

Ahh good! I just couldn't get my brain around that on the fly, so gave up and used no-more-gaps

For an octagon-shaped pergola, the internal angle is 135°, so the table saw would be set at 67.5° (which I guess is 22.5° indicated)

Will have a play tonight, just to see how it goes. I might route a grove in the last face for a bit of detail - I guess I should cut a 135 degree notch in the bottom of a temporary push block, so I can hold the (now thin) strip safely on the router table?

I'd just cut the groove on the table saw whilst you have the saw set at 22.5 ... lower the blade so you take just enough to make the push block and then cut the V with a slight over lap. this allows a kerf wide hollow to form

Test worked well, but wife is off painting a mural on the art-studio wall now, so my opportunity has passed.

Off topic: don’t you hate it when using reclaimed timber for something, and you get to the final cut, and it’s an inch short? I guess that’s a bunch of pre-rabbetted stock for the next project, ha!
