OK here are my first observations and Don feel free to chip in your findings. First I should say I have never been a fan of cheap tools, you get what you pay for most of the time in my experience. The machine looks pretty good especially for the price. Interestingly the machine badge on the side says Sheppach but it is of course made in China. All went together easily and as Don says it can take pinned or unpinned blades .....maybe. First problem I encountered was that the supplied hex/allen key is the wrong size. Probabaly that is just because it has been cheaply stamped out but no great problem just use a better one. Second problem is that with the correct Allen key the blade clamping grub screws jut do not clamp the blade. The reason is that the blade guides have not been properly threaded so the grub screw does not go in far enough to contact the receiving retaining screw on the other side. Also there are no brass heads either ( we have discussed those before) so it is steel to steel or would be if it reached. I tapped out the top blade guide after dismantling the retaining screw and with a bit of fettling it now clamps but the bottom one will be more of a challenge since I am not sure if I can get the tap in without dismantling the whole machine. Would be OK if I had a bottom tap but I don't at the moment.
Fitting pinned blades this is less of an issue and it is pinned blades that are supplied.
I fitting one of those in, set the table ( it is alloy not cast iron but for this price one cannot expect more.) The table has a stop retaining screw which you can adjust and set to ensure it is at right angles.
The machine is quiet and smooth running, so problem at all. I did a quick cut on a blank and it was clean and cut well.
So, my initial thoughts are for the money this looks pretty good. If I can get the bottom clamp sorted out and fit some decent blades I think it will be a good introduction to scroll sawing, which incidentaly I have never done before. I have always just used a fret saw.
