|Thread: Face mill size|
I have a similar sized mill but not the same make as yours. I use the face mill cutter to rough out you can use a higher RPM with a tipped face mill, but watch the swarf, and I have a home made fly cutter which is donkeys years old with a solid piece of carbide to give me a nice Finnish cut.
Have you got a bench grinder as a green grit wheel will sharpen carbide tooling and you need a small radius to avoid the tip shattering.

Personally I would go for a smaller face mill perhaps a 25mm one and a fly cutter to finnish larger areas. Don't stress the mill too much.
|Thread: Lathe tooling|
Have a look at J B Cutting tools they have a web site and you can always call and ask questions over the phone or email. Jenny is very helpful and the have a stand at most of the shows.

Hi Rex welcome to the forum what machinery do you have to help repair these with.
|Thread: New Member - John Payne (aka knightrideruk)|
Hi John welcome to the forum loads of information on here, if you look in the back threads there are lots of other people's efforts to give you inspiration. What are you looking at a rotary table or dividing head.
|Thread: Black Oxide coating|
If you plate or other coat bolts and cap screws etc you can cause embritalnent or lower the tensile strength of items but there is no change to steel strength or structure with blackodising which is done by diping in to a caustic solution at 135 deg which causes a black coating Fe 3O4 which us rust preventative no change to steel structure. That is why Unbrako blackodise their cap screws.

|Thread: Plan/Design for spanner roll?|
I have one made from lorry side material. You can sew it with an ordinary sewing machine and you can pick up small pieces up from articulated lorry repair shop free.
|Thread: Osborn UK|
I still have a couple of 1/2 inch square blanks relay good HSS steel.
|Thread: air blast cooling for mill - solenoid control ?|
I would power it separately as it is useful to turn on and off whilst cutting or after cutting to clear swarf. You can also put a ventory to put a coolant or oil in the air quite easily controler by a hand controle valve.
|Thread: WT2527 15cc Glow Engine|
Thanks for the work you have put in its nice to see the end product in flight. It must be very satisfying. You don't always see the end of a build.

|Thread: Lack of Quill on Milling Machine|
I would get a Bridgeport if you have the room there are very few jobs that can't be done on on one.
|Thread: Mains outlets with USB sockets - safety?|
If I use my phone charger to charge my tablet the tablet posts up a message that I should use the original charger as the tablet charger is rated at 2Amp and the phone charger is only rated at 0.7Amp. I wonder if other items use different Amp rated chargers and what these socket mounted chargers are rated at. Will they overheat if i charge my tablet in one.
|Thread: Power Feed on Bridgeport not working.|
Have you checked the carbon brushes as they are the first things to give a trouble and secondly the cables have a tendency to break inside the insulation as I have found out in the past. Check each cable end to end and move the cables about.
|Thread: Injector help|
|Thread: Thread Bare|
