I have had no luck with cheapo no name calipers.
Anyi have been mentioned in other threads. I have these, really like them:

How about this blokes experience?...

Whoa! I was 100% wrong! http://d1r5wj36adg1sk.cloudfront.net/images/smilies/actions/doh.gif
Thanks for putting me on track Bob.

Polish the "inside" surface? Nup. Paint it flat black, stop it radiating the heat towards the inverter. Black bodies and all that.
Mirror polish the outside, but birds might attack it.

DIY labyrinth? Minimise the clearances, you should be fine.

Can I claim a close second place with this one?

“……common type or special order? “
We bought a couple of lengths from a supplier in Dandenong, off the shelf not special order. Can’t remember the supplier name, but I see 303 on a few local ...

Should be OK if you use type 303, it will cut like mild steel and not workharden.
I'm not familiar with other types.

My mag chuck is still on the waiting “to be fixed” list so no current info regarding cost, but from memory I recall Alpha Magnetics were talking (3 or 4 years ago) about $30 per shot on their...

Bob, I buy dovetails from AB tools in the US but I think they only go down to 1/4"

Harvey have smaller:

Once you have the image it is fairly easy to load it onto a CAD screen, then scale it to the correct size. You can then measure or draw over the top of it.
This is Stuart's scale in Tubocad

Hi Matt,
I will check postage and let you know.

Anyone still looking for tool bit packs? I remember a thread sometime last year.
I have intercepted 8 or 10 thousand before they were collected by the recycler. They are mostly unlabelled, mixed...

jackspecialists.com.au were out in Micham, now Camberwell. Only thing I bought was oil, but looks like he has parts.

Some manufacturers make a high grade collets in addition to their standard ones. Rego-Fix call theirs ER32-UP, Vertex ER32-A
Could that explain it? What brand?
Neil

M12 bolts in a 16mm slot, will be OK.
Neil

Thanks, Richard
That diatribe made my day! :D:D

I have a few Mari toolholders, happy with them, but recently bought some Rego-fix BT40 ER16 and ER32. Made in Switzerland, from the local agent about $100 each (60mm gauge length). They do not supply...

Hi Bill
Thanks for posting the link, looks like a pretty good price. I see beaten up versions come up on Ebay occasionally to and have thought about trying one, but the H&F one looks like a deal...

Hi RC, Mine has been replaced with a Sprecher Schuh 7.5 amps, set on 6 amps. It will still pop a 20A breaker on the sub-board, starting draw is pretty high. In your link, set by rotating the blue...

Looks like the seller is using the same photo for different items:

Hi Rodm , I see one of your chunks of mystery metal is marked "M200"
You are probably spot on about it being a mold steel:

I've been told pieces...

I have been buying them at Dick Smith. Check what they give you,though.

Looks like something from suppliers of aluminium profile building systems, there were 3 or 4 in Melbourne a few years ago.
Here is one : Aluminium Building System

That is looking great, gotta love CNC for patternmaking! To me the webs look chunky enough to not cause problems. Christian, I once left a little jelutong dust on the table... instant rust when the...

Hi Josh, try this:

I have almost finished a pattern for a 200 x 300 x 50 (ish) CI square. It should be on its way to a foundry next week. Not yet sure of the price each, or which foundry the patternmaker uses.
Neil

A Michael Mouse idea which I sometimes use - take the guard off a 6" x 12" belt sander and use the top roller (diam about 3"). Might be OK if you do not have a lot to do.
Neil

I think mine have a pressed steel cover on one side, held on with drive screws.

Bob have you priced ATP-5 plate? I generally use 5083 (which is sometimes badly "unflat"), but for flatness and stability cast plate is great.

Hi Phil,
Thanks for the offer of a ride, but I will make my own way down as I may need to leave early.
Neil

G'day Phil,
Please count me in!
Thanks
Neil

One thought... wonder if the Bunnings "black oxide" is actually carbon black? Unlike iron oxide, it may prevent polyester curing. Not sure how to test it, maybe try burning a small sample?
Neil

Some aircraft aluminium is "Alclad" - surfaced with a thin layer of pure aluminum which will not corrode. Don't go to heavy with abrasives in case you cut through to the alloy underneath. A Google...

I use an El Cheapo. Not sure where we bought it, but here it is:
AFV67 (Brand New) — Seconds World
I use it once or twice a week, had it perhaps 2 years. Renshape dust tends to block the...

I also have an Eclipse chuck which will not completely 'turn off '. I mentioned it to the bloke at Alpha Magnetics in Bayswater (Vic); He said no problem to re-magnetize after I fix it. I bought...

I have bought mesh from Greer Industries before they moved from Richmond (Vic).

Look to be the same people.

One more vote for TurboCad. I use Version 18 Pro for 2D and 3D work. It produces good models which are imported by FeatureCam without problems. I have never used anything else so cannot offer any...

I was always a little envious of the American blokes with the scraping classes regularly held over there. Never thought there would be the opportunity to attend a course in Australia and be guided...

Hi Phil,
Yep, I have an ink roller.
Also I would like to order one carbide insert.
Neil

G'day, I would like to attend. Hope putting my hand up on my first post is not a breach of forum etiquette!
