Thread: Always confused over threads and tapping
21/02/2022 19:24:26

I really have problem with this discussion as some of you are actually looking to mismatch fasteners, why do you think the designers of these fittings made both parts match..I could not in all honesty make stainless or any other material fasteners that did not match. Let’s be fair all the information required for thread sizes /rates /tapping sizes/ clearance/ and ods in the case of numbers is all out there pull it off print and read it.If a jobs worth doing.!!

Sorry chaps but between centres turning is what it says anything else is not.

Thread: Neat cutting oil. (recommendation)
17/02/2022 16:30:40

Bought 25litres of Texaco Neatcut years ago (25) and am now down to the last 3 litres,it’s been very good but as you say what do you replace it with and in a reasonable quantity.

Looks like a very good start especially as you only started with a GA ,I’m impressed.

Thread: High temperature plastics
16/02/2022 20:14:26

Be careful if using tufnol as it has a grain which may affect the strength of you component in a certain direction. The grain is flat with plate (gears) and with bar is rollled so does limit its uses in tension(eg threaded fittings).

Thread: If epoxy adhesives fail to set within 24 hours, is there any hope that they will EVER do so?
16/02/2022 20:06:53

Always mix my two packs with flat coffee stirrers until the mix goes milky ensuring a good mix and plus one for applying slightly warm as it flows nicely, just as an aside whether it’s 5 min/30min/2 hr epoxy that is only rough handling time, no epoxies fully cure in less than 24 hours. I used a lot of slow cure epoxy on cylindrical Mazarin parts and after two days it’s a proper machining job, wonderful stuff in the right place.

Thread: High temperature plastics
16/02/2022 19:37:08

It’s proper name is Acetal and is available in loaded versions for greater strength but have the advantage it is a proper machining plastic machining to tolerances very closely something that cannot be said for Nylon 66 and the Ptfe family. Noggin end good for quality plastics(just a satisfied customer.)

When cutting small threads like 1.6 mm it is a good idea to reduce engagement by upwards of 10 % as we are not talking torque level fittings, nice c/sunk lead in and out the other side as your thread strength cannot exceed the equivalent thread diameter. And use the best cutting oil money can buy (ROCOL RTD) it pays for itself hundreds of times over.

Your picture shows outside jaws

Thread: M&W Micrometer Lock
16/02/2022 09:07:16

Don’t forget the wavy washer that stops the lock unscrewing when spinning the thimble, maybe that’s the original fault??

Thread: Seized aluminium threads Tilley Lamp Pump
16/02/2022 08:48:45

With pulsating tillers it’s definitely as case of cleanliness is next to godliness and one of the best service items is is a new atomiser tube, you may think you can clean it but to be fair have not tried ultrasonics for this!. As for your seized threads ,drain fill with boiling water and use a hot air gun and plus gas. Best of luck, refined fuel sounds a good idea.

Thread: Running a Myford S7 in Reverse
07/02/2022 19:11:35

Been screwcutting I’m my S7 for more than 30 years and have never had a problem. The great thing with the S7 is the mainshaft locking pin enabling the chuck to be well tightened. Also when you consider that the forces for screwcutting are much lighter than for normal turning operatios

Thread: Case Hardening
07/02/2022 11:45:02

As my case hardening is all small parts sub 3 mm I have always had great success with box hardening. The parts come out pristine and a beautiful grey all over

Thread: What Did you do Today 2022

Brings new meaning to the word mate!

Thread: unknown thread of this tap
27/01/2022 22:38:09

I’d have to go for Valve Thread.

Thread: Advice and assistance sought - kickstart gear quadrant
27/01/2022 22:35:37

My Chief has a kicker similar to that but according to the Indian spares people they should be made from a ductile iron mine is, it’s supposed to withstand shocks better and lets face it hard or soft you are never going to wear it out. Plus one for fabrication. Starter ring gears are soft and they last ok.

Looks horribly like a section used on double / triple footway covers to bridge the gap between lids. I still have a little.
