Thread: Making HSS form tools
27/05/2022 19:45:34

surely it must be easier to form your shapes in 01 then harden and polish and then temper?

Thread: fixing loose valve guide
27/05/2022 09:52:02

oversize guide is the way to go it only needs to be a few thou and Colphos 90 is the stuff to use.

Thread: Milling narrow slot on Myford lathe
26/05/2022 20:17:20

I make mine with a slitting saw using a cross drilling jig that’s mounted on the crosslide, it only takes a few minutes and if you use an 1/8 saw you can go either side to get your 210.

Thread: Key for a Cowells lathe chuck
26/05/2022 08:40:31

Hollow point, I notice in your pics that you say that the left and centre keys are cowells but they are different shapes, the one in the centre looks like Jacobs pattern. If the one on the left is correct it can’t be that difficult to copy especially as you need 3 and several other people as well. The body of key with the teeth could be separate to the spigot which could be fitted with loctite later. Just a suggestion.

Thread: Between centres boring bar bit grinding
24/05/2022 22:48:25

I'm with fowlers fury, have just bored a redwing cal for a friend with angle plate on crosslide and did it with 21mm b/c boring bar as per GHT and worked perfectly . well worth the time and effort.

Thread: Any idea what these are for?
21/05/2022 13:02:58

Thread: T-slot cutter
20/05/2022 19:49:09

Thread: What Did you do Today 2022

That's a nice bit of toolmaking Craig

Thread: T-slot cutter
20/05/2022 13:57:39

How do you manage to break a commercially made T slot cutter???

Thread: This trolley/cart could be useful
20/05/2022 13:50:00

I suspect that if you put 100kg on it you would have a hard job to move it over a rough surface and as for having deeply treaded tyres ,what makes the difference none of the wheels are drivers. Instead of a rubbish sales pitch it would have been better to attend English lessons.

Thread: All things Beaver Mill
16/05/2022 21:57:26

That gauge looks unfinished, I have the brown & Sharpe version that must be about 60 years old and it is a joy to use all the sizes are beautifully ground. Is it possible its hooky?

Thread: Hylomar Hylotite Red 100
16/05/2022 11:27:37

Thread: Myford ML4 cross slide
14/05/2022 17:59:13

Is it possible to open up the original threaded hole and fit a top hat bush with two screws (a la ML7) and fit it with 2 ba screws.

Thread: Wyvern crankshaft question
14/05/2022 17:52:46

Modern single motorcycle cranks are a press fit but also the shafts are taken from liquid nitrogen in a controlled atmosphere, we can't do that plus our engines do not put out massive amounts of hp per cc

Thread: Re-boring Grind Wheels
14/05/2022 17:44:25

Yes with you Martin they are moulded with the centre bush in the mould.

Thread: Cowells Milling/ Z axis design
