I have the Sigma 10-20 (Pentax mount). When I did the research it was between that lens and the Tamron equivalent. I ended up going with the Sigma and bought second hand on eBay for about $360 if...

Hi Eddie

I would be wary of an $8 dollar scraper in regards to the quality of the tool steel and its hardness. I have a no name flat scraper that I picked up at a garage sale and whilst it...

Hi Eddie

I second the old file route. I have scraped probably 5 or 6 planes soles using an old mill file.

If you are not fussy, there is no need to do any heat treating to the file, just...

Hi Ray

The E shaped magnet bodies make excellent magnetic chucks. I actually worked for Alan Bottomley during the development of the Magnabend .

I used a bare magnet body to hold the bending...

Hi Brendan

UN threads have a 60 deg included angle, BSF (and BSW for that matter ) have a 55 deg included angle.

Staves are 130mm x 30mm curved to suit a 4 ft dia pipeline. I was hoping they would be thick enough for a table top but if what say is true they are probably going to end up too thin to be useful....

Just looking at your picture, it appear that your dial is divided into 100 segments as I can clearly see the 90 on the RH side of the dial.

APC will post out a CD which took about a week last time I requested it. You don't get everything that is on the DVD however so it might be pot luck if Turbocad is one of the featured programs.
