G'day Dean.

A true labour of love. What sort of prop are you going to set it off with and what size?

A carved laminated mahogany job with brass protectors would maybe do it justice?

G'day.

Rescued 12,000+ emails from a friend's 5 business Windoze XP PC's after he migrated to newer machines with Windoze 7 and Office 2013. (Outlook 2013). Mickeysoft do not have a tool to do this.

In case anybody is 'upgrading' their old kit, I documented how to rescue all your old stuff, P.M. me for details.

G'day.

One point that I noted from Harold Hall's book (Workshop Practice Series #38 - Tool And Cutter Sharpening) was the 180° rotation device. Quite simple but very effective, this improved my drill grinding results immensely. Would probably be beneficial to use one on both types of jig.

On the HH website link (above) look at photo's 10 & 11.

G'day.

Finally got around to drilling an 8" long 0.225" hole in a piece of delrin rod to make a bore guide for cleaning my .22.

I found that keeping the rpm low (about 200) was the key to a good finish - more than that and the plastic melts. Also found that Inox (lanolin based lube) helped a lot. Originally tried it to keep the cutter cool and found that the resultant surface finish came up looking polished.

Here are some photos of the end result.

G'day.

There is an excellent sketch of the clearance on the tap lead in Harold Hall's 'Workshop Practice Series #38' (page 76. SK5). To quote; "The clearance is ground about a different centre to that of the tap itself "

Quite a tricky operation.

I used one a a kid, the name used to crack us up, it's an opisometer

G'day. Many years I read the advice to chuck the files into the garden for a few weeks and let nature sharpen them.

I was recently researching as to how 'Chemically Sharpened' fishhooks were made so deadly (it works btw, don't drop one on your toe) with the idea of using an electro-chemical sharpening process on lathe tool edges, scribers etc. Although I have not yet attempted it, the process looks viable. A goggle search on electro-chemical sharpening can turn up quite interesting results.

G'day, I can see it all the way here in Australia.

You didn't hit the 'ignore member' button by mistake?

G'day. I have an ancient calculator on the workbench, my first ever, it dates back to 1975, it's a Sharp Elsimate.

Just punch the fraction in and voila, decimal units Eg; 3/8 = 0.375. Work to the first 4 places, as fractions such as 1/3 will give you an infinite number (0.3333333333 ..........ad nausuem). (In this case, 1/3 is more accurate imho)

I would be lost without the battered old Sharp actually. I have noted some recent digital calipers that offer a readout in fractions, but this seems to be more of a gimmick.

G'day. Since Jason started this new 2014 thread there have been over 38,000 views.

It appears that many people are stickybeaks and want to know what the other bloke/person/lady is up to.

I must admit that this is one of my favourite threads.

Are you reading this Neil? Maybe a column in MEW called "What Are You Up To" is worth a punt.

G'day

Here in the colonies we still have interesting locations such as ' Three Chain Road'

Whether this was the lengths of the convicts chains or whatever is a mystery to me. How long is a chain?

Still a nice place to live though.

G'day.

I still remember the playground song we used to sing in East London playgrounds.

"Glory, Glory, Halleujah, Teacher Hit Me with The Ruler"

Rule would not rhyme.

Pedants may rule but most rulers are a little more flexible.

G'day.

Following this thread with interest and it did strike me that the O.P. might have reversed the title to "What's wrong with T bolts" and gained the same answers. Given all that, I am still undecided as both systems have their merits....if used wisely at the appropriate time to suit the job in hand.

Anyway, at least I gained something from the debate as must admit I never considered the effect of offset clamping forces. Thank you all for that, .........sooooo much to learn.

Great stuff Les. I have been looking at one of these devices to make an accurate model engine propeller pitch gauge to interface and store propeller data to a laptop.

Thanks * Danny M *

Hi Neil, you can share it with us, we won't tell anyone......

G'day John, it depends on your brand of fag papers (Get the batch number btw )and the relative humidity of the workshop. If you stop breathing for a while it makes a big difference. Where you stand next to the lathe can distort the accuracy. I have an 'X' on the floor just like they do for the Oscars. Micro-Angströms are what people want from a cheap Chinese lathe. Tracking the movement of Uranus is a good start but watch out for Klingons.

Very well said Neil. Here in Oz it's called "Giving a bloke a fair go" and that is what I hope people will do.

Have you drafted the 'contributors guidelines' yet btw?

G'day.

This one works fine for grinding parallel rods (eg; hardened crankshafts) on my C3 minilathe.

I don't often see this one referred to in the various catalogues though, and my mate had to chase my pet supplier to purchase one. For $150 Au it comes with spare wheels, tools, fuse etc.

Apart from the fact that everything must be covered when it's in use and a vacuum header near the work helps (which is common with all TPGs' ). I reckon that it was fair value for the money.

Thanks for that link Lofty.

I was contemplating a 3D printer to manufacture cored patterns for sandcast moulding model engine crankcases.

Maybe the sintered titanium process could make the whole crankcase in one go (that would be sweet). A titanium con-rod might be an affordable practical start though.

I have some titanium in the workshop (undercarriage legs for models). It a pita to machine as it work hardens like crazy and turns drills orange. The swarf burns as bright as magnesium btw, which makes me wonder about the safety aspects of the powdered variety.

Given all that, a titanium crankcase and conrod for a 2-stroke engine would be awesome. Maybe a piston too, even if if the early versions had a conventional ring.

Reducing the weight of the reciprocating parts is the dream of many model engine makers.

G'day.

I heard about this **LINK** on the news here in Oz today.

What interested me was the fact that they 3D printed titanium. Now that would be a handy piece of kit for the workshop.
