That looks a very sensible design, Ian

What make is it ?

Michael, its more a what make 'was' it!

Arcoy were based in Liverpool but I think they ceased trading in the 70s. They made a range of woodworking power tools.

Ian – "Arcoy were based in Liverpool …"

Aaaahhh Arcoy – the Buccaneer, if my brain cell is still working? I lusted after Arcoy tools when I first started DIY-ing. Couldn't afford them then, so B&D it had to be. Years later, I managed to buy an Arcoy dovetailer and used it (with the B&D drill!) to make some 'proper drawers'. The old conundrum of quality versus quantity?

Thanks, Ian

Yes, I guessed it was too good to have survived

I've had a couple of Arcoy dovetailers and they sold very well.

Think Arcoy must have taken over from Selecta. Selecta two speed with 3/8" chuck when Bridges and B & D were single speed and 5/16" chuck, not forgetting the Wolf with 1/4". Looks to be same casing except Selecta had cooling slots. Superb balance, handle in same place.

That advert also shows the Homemaster and Benchmaster accessories – drill stand etc. Probably the cleverest of the drill holder designs and excellent in use. Yet another of my bits and pieces which succumbed to the 'surge'

Good to hear that the kit was excellent because that sort of advertising used to put me off big-time. Bad English, excessive claims, and misleading prices. We have in this example (my emphasis):

• 'The power behind perfection – in all workshop equipment'
• 'The original HOMEMASTER, inimitable supremely, the finest Workshop ever available!'
• 'Strong, sturdy, combining the best features of Lathe, Drill and Saw Bench'
• 'You can start building the most complete Workshop system in the World."

After a big build-up it's far from clear what you would actually get for £2.19.6. To find out you had to post them a 'coupon'. The good old days!

Does anyone know what the individual prices of the Drill, Home-Master and Benchmaster were? That reference to being available 'on the Easiest of Easy Terms' implies they weren't cheap. Mind you those 'easy terms' were probably considerably better than you'd get from any modern Credit Card!

Cheers.

Today my parting off tool holder parted into two parts whilst I was parting a part. Now the part is only partly parted off. My part is to deny any blame for my part in in this part parting problem.

Now I'm thinking of starting a Charity to support Careless Lathe Operators in Distress.

Please send cheques if you would like to keep CLODs like me cheerful in the face of ongoing workshop adversity. It's a worthy cause. Just think – you could help a workshop challenged forum member by buying him a nice comfy armchair…

Here you are Dave, Selecta Home Workshop £13.10s.  Looks like a recipe for cutting off your fingers to me. Especially with the lass showing off her cleavage as a distraction.   Notice who they are made by (bottom r/hand corner).   Or for the pedants, "by whom they are made"

Quick work Robbo!

It's a wonderful toy and I want one. I'm sure Elliott knew what they were doing and besides I still have several fingers to spare.

Cheers,

Silly Old Duffer, I have just installed one of those blades on my newly made rear parting post. I hope it lasts after all the work.

Today I have been lusting after a lathe with a proper screwcutting box. I have had to sort change wheels for 5 different threads.

…

They're superb while they last and it's tempting to push them hard. I broke that one experimenting with an aggressive cut into 1" diameter mild steel at 750 rpm. Insufficient cutting oil, tool right way up in a rear tool post and the lathe in reverse. It went spectacularly well until the dig-in just before the end just as I was wondering if that 'new noise' was normal. I think the holder is designed to break before the lathe.

My combination of tool-post and tool-holder doesn't quite have enough space to let me position the parting tool upside down at the right height. Fixing that is now on my ever growing 'to-do' list: I'm sure 'upside down' will make parting-off safer.

I'm still learning to use these insert parting tools. It's a mistake to be too gentle at low rpm, but overdoing it doesn't end well either! Brass seems relatively idiot proof and aluminium is straightforward provided there's enough lubrication and you don't jam the slot with swarf. Steel? Dunno yet. Probably not as brutal as I was this afternoon!

Rear tool-post definitely the way to go.

Silly O D – The Homemaster was, (in its day), well thought out and had the versatility to make the B&D or Wolf or Stanley DIY drill into a much more useful machine. The mounting was adjustable through 360 degs in pitch and rotation and could be set to quite accurate limits (Home woodworking levels). Its Achilles heel was the pressed steel base which could flex under heavy pressure but I couldn't find a better drill stand until I bought the Wolf version with a built-in 2-axis table and hexagonal column.

This morning, before coffee, I knocked off another helical gear, a small one this time, OD is less than 3". The gear has a 20º helix:

That's so it mates with the previously made 70º helix gear with the shafts at right angles:

I also made a jig for the original 6DP helical gears to see how they meshed. Considering the visual appearance of the teeth, not bad:

I designed a 10DP internal gear and pinion with 20ºPA in the week and 3D printed them yesterday. Today I've made the blanks, and necessary jigs, for both. The exercise tomorrow is to try and make a cutter for the internal gear, and if successful make the internal gear.

I've also had a massive clear up in the workshop involving the horizontal and vertical mills, and the lathe. And of course the floor. It's getting pretty hard work lifting things like the dividing head and rotary table. I blame Father Time, the miserable old so and so.

[KWILParticipant @kwil]

Not only Father Time Andrew, the floor is further away these days!!

Took my 6" ABWOOD machine vice off the Bridgeport today, I had forgotten how heavy they get the longer they stay on the mill table.

Think I must have bought all the food from Aldi and Morrison's for Roger and I in our siege of Coniston speed week.

**LINK**

Being a Yorkshire man ( a Scotsman with the generosity squeezed out) I begrudge paying exorbitant prices for some cafe meals.

If weather was warmer it would have been up with my little tent feeling the fresh air plus all the wonders of nature including being eaten alive by the mosquitos.

That tent has served me well over 30 plus years none of the luxuries of modern so called camping first time out with it was on the Borders fishing there you did get well bitten but to get away from bricks and mortar is heaven.

Setting of at 5am on Monday to see the start at 8am I sincerely hope my friend breaks his steam record with a full size flash steamer.

He said I hope I don't disappoint you as I said that is all part of record breaking and wished him the best.

Will get my speed hat on for the days we are there if any of the motorcycle sprinting or model engineer brigade are at Coniston please introduce yourselves.

Hi Bill,

I got upset when a storm dislodged three roof tiles. As your disaster was the real McCoy I hope life has treated you and yours much better since.

My bonkers brother-in-law enjoys a good crisis. I prefer the quiet life – running out of shaving foam is exciting enough for me.

I was talking to a friend whose Dad I got the super 7 off and told him I bought the Alexander at an auction.

His comment was where are you going to put it as the my workshop is only an average size garage.

So I used a stand I made some years ago for my homemade bench grinder that is now bolted to the bench.

It can be moved easily and is stable but can be bolted to the floor if need be Oh for more room.

The kitchen comes in handy at times as I described to my Sister the useful tools in a kitchen for various engineering operations.

Here comments when seeing the Alexander on the kitchen table was the opersite Sue said is that a pasta maker

I moved onto internal gears today; not surprising as it was the sort of 'orrid day to stay inside. Over the last few days I've been designing an internal gear and pinion, creating the involute curve and building the gears up from that in 3D CAD. I also 3D printed the gears to check operation. Here are the printed gears, steel gear blanks and an arbor to hold the pinion:

To create the tool for the slotting head I created a profile in 3D CAD, transfered it to CAM to generate G-code and CNC milled the shape on the end of a toolbit. I partially ground the toolbit away prior to milling and only milled the profile 2mm deep as the rest will be ground away to create reliefs:

The toolbit was ¼" square HSS; no problem milling it using the same speeds and feeds as I used for low carbon steel, bur with a smaller DOC.

There is quite a lot of tedious setting up prior to cutting the teeth on the internal gear, but the basic operation is fairly standard involving the rotary table. I chose to make a gear with 45 teeth as it simplifies the indexing:

The DRO is used in Y to set the depth of cut for each tooth. On the left is an Excel generated crib sheet with the angles that I needed for each tooth, as a double check. I had some issues with the tool moving in the slotting head holder. So I ground a small groove in the bottom of the tool so that the set screw could postively locate the tool. Except that the set screw then became loose during each cut. So I fitted a locknut to the set screw. After cutting all the teeth I went round again, just for good measure, to check that the depth of cut was the same for each tooth. Here's the finished gear and 3D printed pinion, which seems to rotate smoothly:

Note there is no rounding of the internal ends of the involute curves. At some point over the next few weeks I will make the pinion in steel, so that I have a matching set.

I've had supper, but I can't resist another helping of home made, and home grown, plum and gage oatmeal crumble and yoghurt, plus a glass of wine.

Carbide end mill, presumably? Must try that some time. I would have expected higher speeds to be required but clearly not!

Today I repaired a leaking 1/4 turn kitchen tap for my Daughter. A simple enough job if the correct cartridge can be found. No such luck for me so it involved stripping down the new one that was almost right, turning the spindle and extending the 20 splines for the handle to fit. I did both hot and cold whilst set up, a half hour job that morphed into a 4 hour job but satisfying to do.
