Thread: Muncaster's Simple Entablature Engine

Thanks Jason, much appreciated. smiley

Hi Jason, you mention using small metric sizes with fine threads, could you list the ones I would need along with taps and dies as mine start at M3 or would I be able to use BA sizes as I have 2 to 8 ba in stock.

Thanks Jason, yes it's a shame about College Engineering, there were some useful castings that are now always out of stock.

As I have repeatedly stated, I recommend that people don’t buy anything from them that the buyer cannot afford to throw away. There customer service reeks - if it exists at all.

Totally disagree with you, there are some items that are not up to standard but in the main all I have bought from there over the past 6 years have been fine and even great. There have been instances where goods have not arrived, not all there or broke in a short time but every time I contact them I have had a good proactive response and replacement even with extras to say sorry.

Must be your attitude when you contact them not done it yet wink, oh and I always have photos/videos at the ready.

Thread: Which Stuart models can be done on a 7x14 lathe with no mill?
24/07/2019 19:25:21

There's a chap, Andrew Whale, has been doing a series of youtube videos creating small Stuart engines Learning Turning, he's using a mini lathe and then eventually a mini mill but his first Stuart engine, after an oscillator was an S50. Worth while following his journey.

Thread: What are these used for please?

The first 3 items are for cutting short screws and then dressing the ends square and clean.

Wouldn't they have have needed to have threads in them for that purpose though?

07/07/2019 14:16:15

That did cross my mind and might be right for the 2 on the left but haven't seen pipework in as large sizes as that though

07/07/2019 12:21:01

Hi, these were amongst some items bought and I'm not sure of their purpose. Gentleman was an engineer and clock maker.

Item 1:


Left hans one has BA sizes on it.

Item 2:



Made in USA, Industro

Item 3:




I don't know if this is complete, about 3" is size, one part is hinged but certainly not a knurling tool for the lathe, but could be wrong smiley



Thread: Tungsten Putty?

Depleted uranium is only slightly radioactive, no more than encountered day to day but it has high density hence it's use in bullets and shells.


Thread: Denham Junior Mk2 toolpost
21/06/2019 20:53:44

I'm looking for advice on choosing a Dickson type quick change tool post for my lathe. Problem is what size do I get as best fit and what info do I need to put here for you to advise me.

The Denham Junior Mk2 has a centre height of 5" from the flat, 4.5" from the top of the V. the holding bolt is .5" and is approx 45 mm from the centre of the bolt to the edge of the top slide and surface of topslide to centre of spindle is 14.87 mm.

My thoughts are a tool post that will overhang the edge of the topslide allowing me to drop the cutter holder below the level of the topslide although I expect an avalanche of 'don't/can't' do that!

Any ideas fellow machinists?

Why don't you plan a weekend away in Kent with SWMBO and then deliver them in person?

Cost of of the fuel might be less than that of a courier!


Hmm I think the cost of taking her indoors outdoors and staying overnight make just take a very large chunk of the Simplex money!!!

Nice idea though.


31/05/2019 17:12:23

Sorry, had an away day with SWMBO 'shopping' whoopee!

Destination is Maidstone, Kent. He's planning to collect from there.

The chassis is a 5" gauge 060 approx sizes 34" x 10" x 6" plus a box 24" x 14" x 10". Weight I would guesstimate at around 30 kgs for the chassis plus another 10 ish kgs for the box.



31/05/2019 10:03:41

Hi, a chap from Denmark has bought my Simplex chassis and box of and parts, his sister lives in Maidstone. Is there a way (courier etc.) that would transport it from Herefordshire safely.

Any suggestions (sensible) would be gratefully received.

Yes those milling machines are for 'milling' minerals and is totally legit, been around for years.
