    Mini bench

    Have you got any guide rail clamps or similar? Something like these. If so, another option would be to drill some holes near the bottom of each foot and slide the (narrow) end of the guide rail clamp into the hole. Something like this: You could obviously also add stretchers to prevent...

    Portable (bench-top) Workbench

    I made a little bit more progress tonight. I started by drilling out the holes in the foot and fixed jaw for the conventional vice end of the workbench. The fixed jaw was simple: all drilled from one side; three holes drilled through with two opened to a bigger diameter to depth 10 mm. The...

    Portable (bench-top) Workbench

    Yes, I think that's the video that I watched that had the vice mechanism and is what I'm basing mine on. The prototype works well.

    Portable (bench-top) Workbench

    I started by cutting the beech into lengths of roughly double-plus-a-bit what was needed for each component. The "double" was because there's two of each component type, the plus a bit was to try to allow for the snipe of my thicknesser. I didn't quite get that right and there's a little...

    Portable (bench-top) Workbench

    The first job I did on this (back in January) was to make a prototype of the vice mechanism. The mechanism is based on an idea from a youtube video by Neil Paskin. He didn't provide any dimensions or other details, so I had to work it out for myself (he has also made a plywood version and...

    Portable (bench-top) Workbench

    This project has been on my list for a while now, but I started the main body of work this weekend. The aim is to make a portable (ish) workbench that can be placed on top of my existing bench (or the dining table if necessary!) to give a raised work surface and a couple of different vices that...

    Black CA glue

    RS have got loads of options for rubber-loaded super glue, e.g. RS PRO 20 g Super Glue | RS Components They also sell activators I think.

    Post a photo of the last thing you made

    Spent most of the day today shovelling 5½ tons of type 1 aggregate over the access road that goes up the side of the house to the garages. I think I'm going to hurt tomorrow. Once that was done I had a bit of time to do another practice dovetail, this time using my recently acquired Dozuki...

    Sorry Simon, it's gone to Bharath now, you were just too late. Moderators: please can you close this thread (or whatever you normally do when something is no longer available)?

    Sold Free: Shogun Dozuki Dovetail Saw

    Free to a good home, Either collection or you can arrange a courier to collect from me if you prefer. For the purposes of courier type things, it's 600 mm by 80 mm by about 25 mm (although it'll obviously get bigger once I wrap it in bubble wrap or whatever) and without packaging weighs 250 g...

    Ordering hand tools from EU sources

    I can't help in a useful way by actually answering your question about EU sources, but I have one of these chisels and it's definitely marked up as 3 mm rather than 1/8" (the fact the range is all in metric is one of the things that tempted me to buy them and I've been really impressed by them)...

    Adding potentiometer to bench grinder.

    That SCR module is delaying the turn-on of each cycle, which reduces the average voltage and will increase slip making the efficiency get worse and worse as the speed reduces. Fans are a bit of special case when it comes to motor control. The torque required for a fan is (ignoring losses)...

    Adding potentiometer to bench grinder.

    The "capacitor start motors" that @Spectric is referring to are single phase induction motors (which need one or more capacitor to generate the extra phase to make the motors go round, sometimes with a centrifugal switch to change the capacitance once the motor gets up to speed, although the...

    Adding potentiometer to bench grinder.

    Not true. A rheostat is a variable resistor configured for current limiting; a potentiometer is one configured for voltage adjustment, but a potentiometer can be used as a rheostat. Neither will make a single phase induction motor variable speed.

    Adding potentiometer to bench grinder.

    What they said. You're probably thinking of brushed DC motors. With a brushed DC motor, it is possible (although extremely inefficient) to drop the speed of the motor by putting a resistor in line. The resistor drops some of the voltage (producing heat) and ignoring load, the DC motor's speed...

    Great, thanks. Probably better to send email addresses by a private conversation rather than posting them on the public forum though (I've edited it in my quote, but you might want to edit it in your post as well).
