|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!

|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:

You can stay on the rails with a swing nose frog:

|Thread: MIDLANDS MODEL ENGINEERING EXHIBITION|
No WARCO at this "do" either . On the positive side there may be a little more room to move about!
|Thread: Learning Fusion 360|
Some advice please from users of Fusion 360. I have a small CNC milling machine which I have only used so far for a bit of 2D engraving. I’d like to teach myself Fusion 360 so I can get a bit more adventurous and produce some 3D work.
I am aware of the tutorials that accompany the prog and of various people producing vids on the like of YouTube. I have also noticed a number of books published on the subject.
So, for those that have gone this route already, have you found any of the books available worth buying or would I just as well rely on the video tutorials? Thanks in advance.
|Thread: Blued metal cleading|
Thanks for compliments chaps and apologies for muscling in on Maurices thread. Geoff, not my own design but from plans I purchased which were listed at the time in ME plans handbook #3 of 1978-1979. The drawings are still available here:
I paid £1.10p for my drawings back then!
I thought at the time the model seemed a bit of a titch so I scaled things up and made it twice the drawing size. Mine is just over a foot long and weighs eighteen pounds.
It runs OK on compressed air filmed here some years ago in my tiny and now defunct workshop. I have a better camera now (and a better workshop)
I had not realized that aluminium sheet was/is being used as cleading. When I was nearing completion of this model I needed cleading around the cylinder. I used thin steel shim coated in oil and heated over a gas flame. I was pleasantly surprised how it "blued" easily.
35 years on and apart from some slight tarnish I hope you'll agree it has aged gracefully.
|Thread: Tools or 'things' as therapy|
As the last suns set over the workshop the old chap is wrapped in a trust
with the love of his tools, belittled by fools, replacing a once urgent lust
for those lovely young fillies all fragrance and lace and so very, very enticing
NOW what stops me dead is a Swiss boring head, ground threads, silky smooth - so exciting!
