    David, the 19th Edition was published in 1974 - it says that there was a Total Issue of 1,919,000 at that time (since 1914). I think 6-48 must have been so obscure it was dropped from our editions... 😉 My apprenticeship started in August 1971 and finished in August 1975. Most of the time it was hands-on using various machines (lathes, grinding, jig boring, etc.) ending up in the Planning & Estimating department where I remained for 18 months until I was promoted to Staff and became the Companies Chief Engineering Inspector.... that is when I learnt the art of diplomacy.... once an apprentice, always an apprentice. Left engineering in 1987 to manage other people's money....

    David, thank you for your precise reply, I didn't see any diameter being referred to and was only putting forward 6BA as a possible suggestion as the number of threads work out at 47.92 TPI. I was given the 19th Edition of the Machinery's Handbook upon finishing my Engineering Apprenticeship many moons ago, and I couldn't find any reference to 6-48 within it. Regards MarkR

    I believe that 6x48 could also refer to 6BA (British Association Standard Thread).
  4. I purchased a version four last year from Mark & Sam, happy to measure the width for you. I made up several plywood spacing plates along with a wooden vee block for a rear bag rider to run in/on, this is to help reduce any flexing in the rear support. Not used it beyond 600m yet.

    Update - I have just purchased a new set of FX-120i Grain Scales from Oakleyweigh https://www.oakleyweigh.co.uk/a-d-fx-i-grain-gn-precision-balance.html Oakleyweigh recommended that the tolerances of the M1 Test weights were sufficient to calibrate the FX-120i scales, so I also purchased both 5 gram and 100 gram M1 Stainless Calibration Weights as well.

    John, you have some fantastic equipment there, and thank you for suggesting the FZ series to me. Looking at the cost of the recommended F1 Test Weights (100g & 50g) that you should have with the FX, the combined cost is getting close to just a FZ. Not sure if I really need the WP version ..... Oh I wish it wasn't January when the HMRC needs to be paid.....

    Richie, thank you for telling me about your set up and the advice on purchasing a 100 gram check weight as well.

    Catch-22, thank you for your reply and advice. I thought I would ask as a complete set up was sold by someone on here only last year, it was snapped up very quickly with reserved purchasers. I have been looking at Oakley and the price is still very good.

    Bump to the top just in case members haven't seen this yet.
  10. Thinking about upgrading my reloading equipment to A&D FX-120i scales and Adam McDonald's Auto Throw and Trickler. Is anyone planning to sell their set up? Will also consider Area 419 upgrades or their other reloading items. Many thanks. Update 15/01/19 - FX-120i Grain Scales purchased new from Oakleyweigh Update 18/01/19 - Auto Throw & Trickler ordered from Adam

    Surely rule 1.3.7 covers this point, "All transitions and movements during a course of fire must be done with open bolts and an empty chamber."
