Here is a list of all the postings speelwerk has made in our forums. Click on a thread name to jump to the thread.
For me the easiest way to controlled temper is the flame of a spirit burner with just enough heat to the reach temperture and the object inbedded in a tray with brass filings. Niko.
|Thread: Christmas disaster|
When the oven fails I still have a industrial one as back-up, go's to 900C, probably high enough for the turkey. Niko.
|Thread: 2.05mm or #45?|
No doubt it will differ from drill to drill but I have the impression that with these smaller sizes, if you first use a drill 0.1 mm undersize and than finish with the size you actually want, it gives you a hole diameter closer to the nominal. Niko.
|Thread: Truing up|
"The aluminium oxide has no effect on the diamond surface itself, except to restore its free-cutting action."
and I read that as it only cleans and does not true.
As Nick writes, best seems to be to true the aluminium relative to the diamond, but you have to be careful not to damage the diamond face if you clamp the grinding wheel. Niko.
|Thread: Small slitting saws|
Is it not possible to make the cross piece fit the slot, that way the diameter of the saw is not critical. Niko.

Arntz **LINK**have a good metric range of small slitting saws, it is a German based compagny but curiously only the Dutch and the US agents have the small ones. The direct link does not work, you find it by; Circular Saw Blades - Metal Circular Saw Blades and then at the end of the page you go to DIN 1837-1838. The 2 mm thickness will probably make a slit around 0.02 mm wider. If you clamp two of 1 mm together it will be less accurate and very close to your desire and if you want it a little wider you can clamp a shim from 0.02 mm or more in between. Niko.

|Thread: What do you call this type of chuck?|
Very nice to use but not cheap, **LINK**
|Thread: Facing Error|
Gary Wooding in the posting "Lathe facing convex or concave" made a nice drawing of what the DTI is indicating. Sorry, no idea how to make a direct link to that posting so you have to look it up. Niko.
In theory you messure double the error of around 0.12 mm. Niko.
|Thread: can i silver solder cast iron|
The few times I have done it I sandblasted the parts first. Niko.
|Thread: Myford vertical slide copies|
The original Myford one I have is OK, only problem I had is that I pulled out the studs of the swivel part. It was when in use for cutting a larger size wheel, replaced the original ones with M10 ones. Niko.
|Thread: hardening/tempering a bit of steel|
If you have a gas stove and the part is not too large you can also use that. After waiting until you have the house for yourself, just remove the cap of the largest burner which will give you a good hot flame. Niko.
|Thread: Metal supplier in Netherlands|
Beste is een goede relatie met je lokaal constructiebedrijf, je kan **LINK** proberen alhoewel ze niet echt goedkoop zijn. Niko.
|Thread: Peculiar needle file|
Until a few years ago the thinnest Vallorbe had was 0.33 mm, although not with this type of handle. I used them for work on very narrow spaced music box combs. Now use slitting discs which go even thinner. They have a single straigth cut, were expensive and indeed break very quick. Niko.
|Thread: Trying to identify clock mechanism|
The clock you have is a so called "Zaanse klok". De Zaan is a region just north of Amsterdam, it is a copy of the clocks made in the 17th century in that region, probably from ca. 1970. It was most likely made by Warmink a clockfactory in Almelo in the east of the Netherlands which in 2008 stopped production. The movements were imports from western Germany. These new copies are almost worth nothing this in contrast to the original ones which can be very expensive, see **LINK** Niko

|Thread: Evading VAT and Import Duty|
VAT is a EU tax, when the UK has left the EU it should no longer apply to UK citizens. Niko.
|Thread: Right hand threads|
Most likely someone from the European continent, if threads was a British invention left handed would have been the norm. Niko.
|Thread: Help me Obi-Wan_Knobi, you're my only hope!|
The 8 tooth is also available **LINK** Niko.
Madler **LINK** has the 10 tooth gear, all be it 4 mm width but anyone with a lathe can reduce that easily. The 8 tooth gear will be more difficult to get as Andrew allready wrote. Niko.
|Thread: Bench Vice|
The very best non British made one **LINK**
