Perfect fit no play and just needs to mod slide to take nut.

Thread: sieg mill: normal chuck or collet chuck?
23/05/2019 08:46:43

Hi Ace drill chucks are not recomended for milling and I would always use a collet set to hold a cutter. You are likely to find that the cutter moves if held in a drill chuck and it may push back or pull out to ruin your job. You will also have to have a vice and clamps for holding the work piece. Talk to ARC they have some starter sets unless you gave some equipment already.

Hi Philip welcome to the forum. It helps to say where your locality is so local supliers etc can be suggested. Being an ex motorcyclist what bikes have you worked on. I had a Matchless 650 twin then a Triumph 500 tiger before racing a 500 Suzuki based Dresda, a FEW years ago.

Thread: Equipment required
19/05/2019 07:32:45

Hi i see that you havn't had a reply but i can't help as i don't know about locomotives but I would have thought that you could find out what diamiter the larger parts are and find a lathe which is capable to turn it. But don't restrict yourself as the next job will probably need a larger lathe etc you can turn small parts on a larger lathe but not always the reverse. I would buy what you can afford and as good as you can get.

Thread: Green Grit Wheel
16/05/2019 07:12:04

Hi Nick the first thing I did when getting my grinder was to change the rough standared wheel to a silicon carbide wheel as if you use brazed on carbide tools and boring bars you will need one. I use the fine wheel for HSS tool and drill grinding.

Thread: Shipping to USA
14/05/2019 20:11:12

Hi Matt The rules for shipping go America are terrible and even the wood and packing materials must be to regular US standard. Any oil and coolant etc must be removed and certified clean. Get an agent to prevent it being impounded and or returned.

Thread: fobco drill
14/05/2019 17:53:02

I have had to repair a similar problem with a Fobco bench drill it had been used in a toolroom to drill graphite and the graphite was abrasive so that the clamp wouldn't lock but the and of the ring closed when tightened. I just had a larger slot cut with a wider slitting wheel to allow it to clamp.

Thread: Drummond type m

Hi Dan There is a mod to fit an extra thrust bearing just behind the chuck location and into the bronze bearing. The bearing is a roller thrust bearing with two hardened washers and fits perfectly into the space there now. It gives more support to the spindle and reduce chatter. I bought mine from Simply Bearings NTA1625 Needle Roller Cage Thrust Assembly with 2 TRA1625 Washers 1.00x1.562x0.1381 inch (NTA1625-TRA1625) = £6.41

Hi Phil The floor standing one has a solid column and a wind up mechanism for raiseing and lowering the table. It would have to be bolted to the floor or a substantial plate fastened to the floor of a wooden floor. You could make a new spindle with a Morse taper, they were available on some models.

Thread: fly cutter or face mill
08/05/2019 21:33:55

Hi Martin this is the fly cutter that I use it has a solid tungsten carbide piece as the actual cutter.

20181206_080315.jpg

It has a 12mm diamiter shank and a 25mm diamiter body with a grub screw to hold the carbide in an angled hole easy to make. If you like I have a spare carbide piece you could have to make your own. You can run it at a fast speed and get a lovely finish and little or no wear on the cutter. Send me a PM if you want me to send the carbide.
