Thread: Cleaning glass.
16/10/2021 13:07:31

Slightly soapy water, a good, clean microfibre cloth and kitchen roll to dry.

It works for me, but do keep the water & cloth clean to prevent the dirt going back onto the glass.

Thread: Small bandsaw needed

Is it the join in the blade that's causing the movement?

This Cutmax was linked to on another thread. I think it's a rebadged Nebes 125mm cutting capacity saw like the one in my album.

Thread: Paint stripper

Not paint stripper, but Bahco Tungsten Carbide scrapers are now my go to for paint removal on cast iron, the 625 is probably the most useful, you'll wonder how you got by without one when you use one.

I removed a few layers of paint from these castings with ease, it comes off in one scrape, as it comes off in dry chips it's probably one of the least messy methods of paint removal.

The blurring around the last picture makes it look like a miniature version of the real thing.

Wilko own brand paint stripper removed some epoxy two-part enamel very well for me. Put plenty on, leave it there longer than recommended and keep knudging it into the nooks & crannies.

It was far more effective than the premium brand I tried.

Thread: Unwanted Taper
04/10/2021 12:39:34

It should be straightforward to get this right if the headstock is separate from the bed.

Use your level across the bed at headstock & tailstock end and shim to read the same - this will verify that the bed is straight and untwisted. It's the starting point for everything else.

A test cut without tailstock support will show the taper that's causing problems for you, so it's necessary to loosen the headstock mounting bolts and carefully reposition it until its axis runs parallel with the bed. Very light cuts with a sharp tool will confirm the adjustment.

If the headstock & bed are in one piece then you have a harder problem to solve.

Thread: Clock Stand with a difference

The cylindrical square should be your friend here.

Mount the square and the column/base close to one another on a good surface plate, in such a way that they can't easily move about - maybe add some weights. Then measure the distance between them at top & bottom, with gauge blocks or similar to determine how out of square things are. Then you can make your fine adjustments from there.

Thread: M6 thread locking/stiff screw
01/10/2021 17:14:07

I would imagine nail varnish would work too - just apply it as show in Michael's post above.

Thread: Bench top band saw
01/10/2021 13:31:58

The Cutmax looks like a re-badged Nebes, which is what I have and is a very good saw indeed.

The Nebes cuts consistantly, is well built and very quiet in use.

As it also has iron wheels with no rubber coating it can be use wet or dry too.

Martin.

Thread: M6 thread locking/stiff screw
01/10/2021 10:30:50

I've used a spot or two of super glue on the screw with good results.

Just apply to the thread and let it harden before screwing it in.

Thread: What Material for this Application Please?
01/10/2021 10:21:52

Tricoya waterproof MDF would probably do the job. You could finish it in almost any way you like.

Thread: CNC Lathe Scratch Build
29/09/2021 11:32:48

There's a whole range of these CNC lathe controls here.

I notice UK ebay has a GSK980TDc available for a little over £1000 at the moment, but some of the buttons have Chinese characters - still worth a look, I think.

Martin.

28/09/2021 15:53:03

Are you sure?

This is from the manual I downloaded.

Get the GSK980TDc manual here.

28/09/2021 12:46:39

Surely this would do it? smiley

Could this open-source project be useful?

That looks interesting, John.

There's also a 'Polarizing Converter' that may be of some use to Joe here. There is no 'C' axis label available, but if the basic conversion is OK, then it might be a simple Search & Replace in Notepad.

Martin.

It looks like Centroid make a C-Axis controller, but at a price. You'd be looking at around $2300 for the board & software.

This is from the PlanetCNC gcode reference - I don't know if it's of any help, I'm just posting if you weren't aware.

G15 - Polar Coordinate Cancel
Usage: G15
Cancel polar mode coordinate positioning.
Parameters:
#<_polarmode> - (RW) current polar mode
G16 - Polar Coordinate Enable
Usage: G16
Enable polar mode coordinate positioning. In the polar coordinate mode movement end points are
specified as a radius and angle. Origin is determined by the absolute/incremental position mode
setting.
The current plane setting determines which word is radius and which is angle.
G17 – XY Plane – X is radius, Y is angle
G18 – ZX Plane – Z is radius, X is angle
G19 – YZ Plane – Y is radius, Z is angle
Parameters:
#<_polarmode> - (RW) current polar mode
Example:
(square with corners -30,-30 and 30,30)
G0 X0 Y0
G16
G00 X42.4264 Y225
G01 X42.4264 Y135
G01 X42.4264 Y45

I'm very pleased with my Nebes 125 band saw. It's motor is nice and quiet - almost sewing machine quiet and the build quality is reassuring.

It was expensive, but feels like it would last a lifetime.

Bought before leaving the Common Market, it came from here: with free delivery.

Some pictures can be seen in my album.

Martin.

Edited By blowlamp on 20/09/2021 11:02:43

If I have to ask the price then I probably can't afford it.

Peter

I think the price isn't showing because it must be out of stock at the moment.

I paid €547.74 back in November 2020 and that was delivered from Italy to my door here in blighty.
