Does a bare wire work as a wick ???? I have my doubts.


There's no point saying it doesn't work, it plainly does, what we need to know is how. Capillary rise doesn't need a tube.

I am given to understand that once the wire is wetted surface tension drags the oil down the wire. A bit like pulling a string the end will always follow. regards

Although my lathe has got a flood coolant system on it I generally use a squirty bottle when needed as the flood makes far tooo much mess. Same on the mills unless using a big face cutter then I use mist coolant. I got fed up with wet floor, bench etc with flood coolant. On Ali I use a WD40 squirty bottle.

I have a very old stationary engine of unknown make that has wire wick oilers. As it is a non runner I have never tried them but they looked original so left them as is. If it had been a runner I may have thought "what idiot put those in" and changed them to cord. We live and learn. I subscribe to Robs channel and he does expel quite a few myths on brazing, casting and a few other things.  He also builds engines from scratch.

Ordered SKF 6201 bearings on Friday14th @ 14.30 & delivered by my postman @ 10.45 this morning. I selected 5 day free delivery as I was in no hurry for them, Excellent service from them. Its the first time I have used them but they will be my goto bearing supplier from now on. No connection to them.

Neil, The protractor in your picture above or something very similar is on my to do list ( steal idea) for the cutter head tilt.

A little update. I machined the spindle of the head down and made a sleeve for it to enable me to try my Stevenson ER32 block as a temporary measure. I was going to use a Cutwell long shank ER32 holder but it has a 10mm hole up the centre. This brings some difficulties when trying to fit the dial and handle to it. So thats on the back burner for now. When I need to do flute sharpening I will revisit this part.

The rectangular mounting block for the head on the compound overhung each side of the swivel by 0.040" so milled it down so there was only 0.005" overhang. This will make it easier to fix the hinge plates when I get them done.

Am now working out the dimensions for the hinge plates that will be fitted to the sides of the block and be swivelled from the compound. I will try to incorporate some kind of protractor similar to one in Neils post.

The compound is not quite as well made as it first appeared. Nothing was square and looked if it had been sawcut and filed to shape. The block on the top was out by about 3 degrees so I had to sort that out. Now it is all square I can get on. I mounted the head to make sure I had enough clearance to sharpen cutters up to 16mm.

A few pictures follow.

Thread: That Strange Calculator Again
13/01/2022 15:15:30

I have trawled through my countless calculator books and have come up with nothing. Also spent many hours on the internet since the first post and nothing found. As a collector of Mechanical calculators and slide rules I will be very interested to know its origins & usage.

I ordered a 10mtr Cat7 network cable on the 16th December. I waited untill January 5th and then contacted the seller.

He offered to send another out. As I was in no rush I told him to wait untill the 10th and I would let him know if it had arrived or not. Well lo & behold it turned up on Monday the 10th. I managed to catch the postman and he told me that our round had only been partially servised ? Only letters were being delivered and all packages held back until they had enough staff to deliver them. So a 1st class package took almost a month to arrive. Even the postman could not understand why this happened as he said they had very few people off sick or absent. I went to Curry's just before Xmas to get a new DVR for erindoors as the old one was a bit long in the tooth and starting to do its own thing. I checked online and they had stock of the model I wanted in store locally. Got there and a pimply youth came slouching over to enquire whether I was just looking or actually shopping. I pointed to the item I wanted and said "I would like one of those" Hmm he said I'll see if we have stock. After some key thumping and shaking of pimply face he looked up and said "we have none in stock". I told him that according to their website they had stock. Oh dont take any notice of the website says he, Covid has affected our stock levels and we have none. OK says I, I will take the one on the shelf I dont need the box or the leads just power supply and unit. He said "Cant do that, its our demo model". "Why would you need a demo model when you have no stock ?" asks I. No answer to that just a dumb look. With that I walked out went to Argos and got one there. I think as others that many companies are just using Covid as an excuse.


Edit.  As I was typing this post I heard mail come through the letterbox. Well 4 Xmas cards arrived all posted in time for the grand event.

Thanks for the feedback Nigel. I was thinking along those lines as well. I would like to have it so it will tilt using a screw mechanism of some kind. So making the block hinge as you suggest and adding some form of scale to measure degrees is probably where I am heading.

I have been in contact with Cutwell with regards to a long shank ER32 Collett holder. They say the shanks are machinable with carbide so I will think about ordering one.

As a quick and dirty solution, could you build the angle into the holder?

Yes it would be easy to make a new block to sit under the holder ( or fit a shim under one side) but would limit me to a fixed angle. I would rather the block under the holder could be tilted to different angles primary & rake angles. Hope fully not too much of a job. Making models to test a few things before I machine the parts up.

That's a bargain and what a great basis to do your upgrades. I've been looking for something similar at a sensible price for ages. Well done!

Thanks Henry. Yes I saw it and put in a bid for £150 what a shock when I won it for under £70. Gives me some spare £'s for er32 holder. cup wheels & bearings. smiley I will take my time and work out the best way to go about it.


05/01/2022 13:46:51

I picked up this homemade grinder for less than £70. It is quite well made and feels very rigid. The dials have excellent graduations all round. There is no play at all in any axis on the swivels. The lead screw has almost imperceptible backlash.. The motor feels ok but does rumble a tiny bit so I will change the bearings at both ends. The tool holder is a bit strange in that it is just a 8mm slot with 3 socket head cap screws to fix the tool in place. I will modify & change it to an ER3 collett holder. The biggest draw back is that it has no tilt to the head so will not do compound angles. I need to have a good look at it and see if is possible to alter the parts below the head to get it to hinge up & down to a good degree of accuracy. Maybe I have to remake the compound completely. The unit is 20" long x 12" deep x !6" high & weighs in at almost 20Kg

Thread: What tool do I need? I need to measure the radius of a tiny fillet on a 90 edge.
04/01/2022 14:37:33

I have a set of gauges that Peak4 linked to in his answer. They seem to be accurate enough for what I need. At 0.3 the radius is tiny and needs a set of magifiers along with my reading specs to be able to actually check the radius. They seem to be ok unless you are working to atomic standards.
