It's the same principle, I'm sure.

The PCB has three pads, I may wire up three croc clips to them for things like big power transistors.

Do you know if they work on things like FETs or IGBTs?

Good question but I've never tried anything that I did not already know what it was. I bought it because it looked to be an indispensable tool, in practice however I have only used it about four times mostly just to identify the pinouts of a transistors when I could not be bothered to look at a data sheet!

After a vain attempt (Started last year) to build my own QCTP to my own design, I gave in and bought one from ARC., The standard mini lathe toolpost is difficult. The nasty aluminium cheap one is nasty and cheap - and I NEVER managed a decent parting off.

This one (the model 000) is reassuringly heavy, nicely ground and works very nicely. I expect several old boys to pitch in with 'buy cheap buy twice' and their right. I should have spent the dosh in the first place.

This one has parted some 20mm steel with no drama at all and sunk through an ally bar like butter.

sigh.

I'm using mine a lot at the moment to sort out my muddled collection of components. While I was sorting transistors into NPN and PNP it successfully spotted a 2N3819 was a JFET.

The various adverts on ebay suggest there are a few variants about. I think the original LCR, NPN & PNP, & Diode unit has been extended and/or the software upgraded. If buying one, may be worth checking the detailed spec to see if you can pick out the most up-to-date model available.

In operation, the unit is a little erratic, and it is sensitive to dirty leads. Mostly I'm impressed.

I use mine without a box and what with the battery flopping about and all, it's not a good idea. Making a box with my limited sheet metal / plastic instrument box technology is bothersome because of the need to provide access to the display and especially the DIL socket. A 3D printer would solve that easily - I want one!

While I'm old enough to be a member of the grumpy old git club I'm not old enough to be a member of the told you so club; so I won't mention it if you don't. smile

Hooray for 3D printing!

Last night my steplad asked if I could do an adaptor to join two small pipes. Took two tries to get it right (hard to measure flexible pipe accurately and one needed a taper), and my reward is a bottle of King Goblin

Just finished the oil pot for my rockerblock ic engine not a simple job .I finished the water jacket yesterday this was difficult as I couldn't source the O rings.I ended up stretching a pair daily on a stepped mandrel but I still couldn't get the cylinder through without forcing the ring out.I had to deepen the groove in stages and add a slight taper to the end of the cylinder.When it did go through I wasn't sure that I hadn't dislodged the rings .I filled the jacket and was relieved to have no leaks, a result at last.Not much left to do now but the biggest job will be making the carburetor.

Managed to thin the sides of my coupling rod for Rob Roy so it ended up 1/8" thick instead of 3/16", should have checked the drawing !!! Luckily it was the first one so can do the others correctly and make a replacement 😠

At least it wasn't for a 7 1/4" King!

Overtook a 2-6-4 tank engine. It was doing 45mph backwards on the M4 around Slough at 20:15 last night. Think it was no 800078 but google doesn't find that.

Brazyle it´s a zero to much. Google 80078 and you will find it.

I did this today...………………………….shaper 1.jpg

but before doing that, I should have done this...……………………..

shaper 2.jpg

My concentration was centered on the cutter but as soon as the machine ran I noticed the vibration and hit the red button and immediately gave myself a good earful of abuse and considered myself lucky that I didn't get injured by the handle flinging itself into me nor damaged anything in the shop !embarrassedembarrassed. Just might fit an extra safety micro-switch to be tripped when the handle is fitted.

Which shaper is that?

Oddly enough, on my 10" Royal shaper there is less guarding, but there is a round knob/handle to turn the mechanism for positioning the ram. That's far safer than a cranked handle, even it it's removable! blush.

You are not the first and you will not be the last.

Join the club.

Though it's nowhere near as bad as the old "leave a lathe chuck key in the chuck" chestnut.........

Looks like a Boxford to me.

The removable cranked handle should do the cross feed and the vise too. Another sq key tool and that's it on a Boxford for EVERY adjustment.

Spent an hr in the cave today & made one of these for my daughters wedding dress, buttoning it up might prove a little difficult for the mother of the bride, Stainless steel & wood dowel...

My first thought was that it was a key for unlocking a chastity beltyes

How much tension are you expecting to put on that dress??

Are you selling her? does the poor bloke know what he is buying?

Have you made a tool for safely letting it all out or will they press a button & it all goes with a massive twang!!!!?crook
