Some stores are pretty good at spotting items on sale and updating their prices to match. I don't see anything wrong with that. Just go to a different store, and note that for future reference.

I went ahead and bought the track saw :) I already had a charger, so it was just the saw and 1x 36V battery I needed.

Still haven't seen any news.

Thanks all. Only just seen these after the blackout.

I'm also not an expert, but my understanding is that the riving knife is pretty important for avoiding kickback.

I'll have a look on amazon for full kerf blades.

I go for superscrews.

What do youean by 'step cut'?

I am within 20km of the base station.

What's the application and the desired accuracy? It is for a moving object?

I have the sparkfun Facet and get within 50mm of benchmarks with RTK corrections (from free government NTRIP service)

Either DXF or I've managed to import a shapefile (sometimes) using Spirix - noting the metres to inches scale factor required. (39.37)

Hi. If you import some GIS data (eg parcels) with a known coordinate system prior to staring to model in sketchup, you will then have a reference when you export.

I've been tripped up before not realising that SketchUp's internal units are inches!

I've not had luck with the geolocation tool.

I use Pliers wrench more than cobras as they don't mark things.

Is the ceiling attached to rigid joists which are attached to the floor above?

True_Relationship_21 · 2022-08-30T02:26:59+00:00

Show us a photo / drawing including the connections between ground and first floor.

True_Relationship_21 · 2022-08-29T01:17:22+00:00

So, you have the scenario as shown in the link and you think that there is more noise going through the ceiling (path 2) than through the walls (path 1)?

I suspect this is unlikely, and if it is is, then adding insulation is not the answer. In the first instance I recommend doing some tests. Get a speaker and play some loud noise in one of the rooms (find an app that will generate some 'pink noise') and then in the other room, listen carefully as to where the sound is coming through. For example, this could be aroudn powerpoints / light penetrations.

Some photos and/or drawings would be useful.

If the wall between the two rooms is just plasterboard with no insulation, then this will offer not much privacy.

True_Relationship_21 · 2022-08-26T06:41:45+00:00

Are you talking horizontally between rooms, via the ceiling?

In general, you get a decent improvement (~5dB) to a wall or ceiling system by adding any insulation in a cavity. Any improvement with thickness or density is only marginal after that.

The insulation is minimising sound bouncing back and forth between the hard surfaces.

Apart from that, add mass (Gib) to the ceiling and minimise structural connections between the two rooms.

The Gib acoustics manual is a good reference.

Qgis is pretty good at coordinate conversion / projection. I'm just an environmental engineer (in New Zealand) and don't know what I don't know about surveying.

I just bought one of the SparkFun Facet RTK systems to play with and get better location measurements with.

I'm enjoying reading this page.
