|Thread: Best way to cut HSS tool blanks from bar?|
Jim, I use a similar abrasive disc for slicing HSS. Not sure whether it was ALDI or LIDL but I bought a stand to fit the angle grinder which allows it to be used like a chop saw - it works well.
The only tool steel I know that cuts when red hot is Stellite. I am not aware of any grade of HSS that would cut at those sort of temperatures. In fact, when referring to the cutting/shaping of HSS in the cutter grinding dept. where I laboured a spell the advice given was "if its brown its cooked, if its blue its buggered."
The above refers to the 1980's so apologies if things have moved on.
|Thread: Any other bowmakers on here?|
I posted my previous without reading the thread (slaps forehead!)
There is supposed to be a good crossbow on Antiques Roadshow @ 8.00 this eve. BBC1.
|Thread: Recent threads|
Hello Martin - Can't say that I have noticed any increase in verbal "bovver" of late but that might be because I only read threads with titles that look interesting to me.
By the way, I looked for you and your engines yesterday at the Stow-Cum-Quy show but didn't spot you.
|Thread: More mystery tools|
Real works of art, a pleasure to view. Interesting that the engraver has been thoughtful enough to depict your target just in case all that crusted port and vintage cognac has clouded your memory.
Clive - Sorry to hear about your pain. I can sympathise. The disk at the top of my old spinal fusion op has prolapsed and has been giving me stick for many months. Neither Ibuprofen or Paracetamol will pacify it and Co-codamol and Tramodol only made my constipation so spectacularly chronic that I ended up in an ambulance on the way to A&E a couple of months back. A re-bore was avoided but it was a close run thing!
I have not conquered the back pain by a long way but after 4.30 pm of an afternoon I find a steady oral infusion of Scotlands finest brings me some peace. As for the other problem, the odd cabbage and onion curry can bring a little light relief (well it makes me laugh).
Hope you bee sorted out soon.
|Thread: Work Shop Talk - Tour of my Work Shop|
This thread has reminded me that I need to take photos in the workshop for insurance purposes. I have nearly finished taking the pictures (a lot) and would like to make them viewable on this thread for any one on here who might be interested.
Two things then:
1. What would be the easiest (free) prog/app to batch shrink the pics for upload?
2. What method to use to make a LINK which would make them viewable on here?

|Thread: What Did You Do Today 2019|
Took a break this afternoon from a sweaty workshop and the fiddle of milling 1/8” steam ports. Logged on to a website that offers five free ebooks a month and selected “engineering” as my category and was offered this book authored by one Gints Jekabsons :
"Adaptive Basis Function Construction:An Approach for Adaptive Building of Sparse Polynomial Regression Models"
…………and wondered if they had steam ports as well. Then it dawned on me ---- hot air engines don’t have steam ports…doh!

I think it was Clive the bee man who recommended scraps of leather as a good source of case hardening carbon so I have collected a small sack full ready for when things get serious!
By the way Clive, how are the bees doing these days?

|Thread: Source of plastic rod|
Good info from all - thank you. Donkey, you appeal to the cheapskate in me. I will checkout both of those salubrious retailers toute suite.
Looking for a supplier of hard, tough, round plastic rod. It needs to be easily machinable, take a polish and lend itself well to being engraved. Diameters? Anything from 1" up to about 3". One 300mm'ish length of each would be more than adequate.
If it was possible to obtain man made ivory then that might possibly be just the stuff I'm looking for. In fact, if it were ivory coloured so much the better. Does such a material exist other than in billiard balls (phenolic resin) ?
|Thread: Spotted in Pewsey|
When Aunty Grace and Uncle Fred used to keep the Royal Oak at Wootton Rivers in the '50's my brother and I used to walk from there to Pewsey through the lanes scoffing wild strawberries picked from the steep verges. I don't remember seeing that watchmakers shop in Pewsey though.
|Thread: Snail Problems|
Wife and I will review our use of slug pellets after reading some of your posts. I'd hate to think that they were causing harm to our tasty little hedgepigs.
Rik (Joking and serious at the same time!)
Howard - I can only assume that your wife does not want to hurt the critters. To protect our hosta's my wife generously provides the snails with a rich diet of slug pellets. They don't like it up'em!
One neighbour with a kindlier streak used to collect all she could from her garden and propel them into a nearby field with a tennis raquet……..mad old bat

|Thread: Mounting an ER collet chuck|
“ Or shallow so the bolting outer face contacts the backplate.”
Just that Rich!
|Thread: Model Engineering Overseas|
"You would enjoy this article then about a small lathe made by inmates of a Japanese POW camp in WW2 LINK
A truly amazing story."
I am amazed that those blokes achieved what they did under such conditions way back then.
|Thread: Suitable wood for making tool holders|
I have a swiss made Kaiser boring and facing head in original fitted case. I could never be described as an expert "woodman" but if I were to guess I would say it was made from beech.
|Thread: Total newbie question - Collet identification|
I have a left over set of those collets from my old peatol - long since moved on.
Here is another type altogether - this is a 1/4" collet.:
Overall length = 27.00mm
Rear locating register diameter = 9.98mm
Any ideas what for?

|Thread: Where has my post gone?|
Mart - It happened to me once. These days I make sure the pics are in the album before creating saved text in Word after which I paste into the dialogue box. Just a matter then of adding the photo/s. Maybe not completely foolproof but it works for me. ( Pete - can you let him have a postcode ?)
|Thread: Warco WM16 machine vice|
The vice on my WM16 is here:
Jaws are 90mm wide, open up to 67mm and are 40mm high. It cost me £7 if I remember correctly from a bloke in a field one Sunday afternoon some years ago. First thing I did with it was mill a slot underneath and fit a key to locate in the table slot. Saves clocking jaws every time the vice is refitted to the mill.
I have a 6” diameter rotary table purchased from WARCO who advised only the 4” but I though that would be restricting. It came with several dividing plates. Howerd Lewis of this very forum has a correction table available for use with the Vertex HV6 which I believe applies here. If not I’m sure he will correct me. Details here:
