Thread: Hello

Hi Tom welcome to the forum. Where are you based as it helps to suggest local supliers etc. I make tooling and whatever takes my fancy. I have recently made some jewelry bangles, (with my granddaughter) a simple wobbler steam engine, a drill/grinder attachment for the toolpost on the lathe and other bits and pieces.

Thread: Myford Super 7 Lead Screw Not Turning
08/04/2020 07:55:46

Have s look at the Myford web site as it gives an exploded drawing as well as a parts list. Looking at it there is a taper pin on the drive shaft which could be the weakest link. Can you try and rotate the input shaft with the drive gear disconnected to see where the disconect could be.

Hi Oliver welcome to the forum. There are many members interested in like projects on here so ask away but it is worth visiting local clubs as there is a wealth of information there and they may have machinery that helps with the build. They are usually friendly groups but you have to ask if you want help.

Hi Jager welcome to the forum. What sort of tools have you been making. If you need to put pictures on here look at the forum page in the black line then frequently asked questions tab. The left hand threading facility is just that you can cut a left hand thread by inserting an extra gear into the gear train, on the headstock, to make the leadscrew rotate in the opposite direction to it left hand thread. Just ask on here if you have any questions but a picture usually helps and shows off what you are making.

Thread: New Mill
03/04/2020 12:21:33

Hi Keith nice to have a nice new machine. When you remove the grease that protects the slides etc. you will need to lubricate the slideways and lead screws with a slideway oil I use 60 grade. don't forget to check the spindle taper inside the spindle as that will need cleaning and not lubricating. The small clamp handles for the ways are a bit of a nuisance as it is possible to break them by positioning them so they catch as the slides are moved and clash with the castings. check for play in the slides after cleaning and oiling they may need adjusting. I didn't check that the headstock locking was tight when I first got my machine as it was lightly tightened but moved when I started to cut steel test piece and it cost me a new carbide cutter. also check the head for being square and tramed up. Make sure that it is bolted down before using especially tilting the head.

Hi I have been making a wobbler from Steves workshop web site and one of the last things on making it says find the extreme position of the cylinder and mark the port with drill through the exhaust port but the position of the port is on the drawing. I just wondered if I put the hole in to drawing will it work or is it better to mark with a drill and how critical is it. If anyone has made one your help would be appreciated just so I don't have to adjust the hole after drilling.

Thread: Source of Small Extension Springs

Hi Brian Have you tried Ashfield springs. I have bought from them local but you may have to have a minimum order price. I added a few extra springs on to make up order. Nunbrook road Huthwaite.

Thread: Mystery Sandvik inserts
01/04/2020 18:03:41

Yes they sit on top of the insert and the clamp holds them in place. You adjust the top plate nearer or further from the cutting edge, to get best chip break, which were flat triangular tips with about a 1.5 to 3mm tip radius negative rake and no front clearance except for tip angle so you can use both sides of tip 6 cutting edges. I could take 0.250" cut feed about 0. 050" at 3000 rpm Roughing out. The chips fly and the tool got hot evan with coolant.
