One of my favourite tools is the small proxxon drill press. The manual suggests every 10 hours of operation to lubricate the bearings but does not specify what oil to use. I emailed Proxxon and this was the reply: The TBM 220 drill press may be lubricated with a wide range oils, so we do not recommend any specific lubricant. Sewing machine oil is absolutely suitable. Maybe this will be of help to others. I am not sure what I will use, I think probably what ever car motor oil I can get my hands on. Vaddoc -
Hi. I have purchased from a UK company some drill bits of various sizes. This morning I went to use a 1.1mm drill bit on annealed brass. I did not check the bit as it was new out of its container. Put it in the drill and rubbish. Thought no more of it and replaced it with another new one. Same not cutting at all. Just skidding. I had a look under a X400 microscope. There was no tip. Had been ground but totally wrong. Checked all the drill bits one by one and all were sharpened differently. Only one had a correct edge Contacted the company and talked to custamer services and just not interested telling me it's me. LOL. Being a Toolmaker and engineer most of my life I know what's right and wrong. They did not even want me to return the bits... And no replacement or refund. No I am not going to name the company but I have made a complant to trading standards UK. So... Buying drill bits beware. Regards Antony. .... I feel better already for voicing it

While researching for information about the gun drill on my Victory model, I also watched attentively some live fire videos on you tube. Once into a bit more into the subject, one realises plenty of more details, one does not see the first times, when the noise and smoke and the effects are still taking to much attention off ... The classic: Live Cannonade Fire Carronade at point blanc range against a ship mock-up. The side tackles are loosened before the shot. The blast out of the touchhole does not appear that bad. The outside of the hull only shows little impact, the inner side tells a different story. http://www.youtube.com/watch?v=U6foV4lmL4A Canon LIVE FIRE test - 18th century canister shot http://www.youtube.com/watch?v=lMILWzE9f0k Great to see the loading. At 0:37 one can see the leather protection for the thump to seal the vent hole, seealso the picking of the cartridge with the vent pick, the slow ignition and the long time until the cartridge ignites and the relatively little recoil. Also nicely to be seen in the final slow motion how cartridge and wad pads are flying off, always a risk for the wooden ships. Civil War Artillery Drill, 12 lb. Napoleon Wonderful gun drill with plenty of details Civil War Cannons http://www.youtube.com/watch?v=VHVOHAfS5EY Shooting barrels with little recoil Hornblower cannon firing Nice to see the loading. Seeing the use of the wooden handspike to adjust the coins clearly shows the reason d´être of the steps of the carriages sides. Small recoil, as just imaginary bullets were used. Cannons of the Civil War (1861 - 1865) http://www.youtube.com/watch?v=x_UtQ5v_M30 Nice pictures of rolling fire during reenactment at the start, then slowly gets repetitive ... Shooting the Bronze Swivel Gun with Canister Rounds 6 Pounder Cannon Shoot-Field Artillery-Civil War Uniforms http://www.youtube.com/watch?v=ivaMHdKeaz8 Blowing up cars with a Civil War Whitworth cannon.wmv Great to see the time the bullet take for the flight. Interesting is the start and the grand finale - I guess they helped a bit with pyro tech here ... 32 pdr Field Howitzer bigger caliber, much more booooom and violent recoil ... Civil War 12 pound cannon into 50 gallon drums (Antietam) At 0:16 and 1:50 one can again see the leather protection of the finger, and how the vent was closed/protected with it. For once I am not saying "enjoy" ... Daniel PS: Please also see the topic "why do hot guns jump violently": http://modelshipworld.com/index.php?/topic/3963-why-do-hot-guns-jump-violently/
