Gentlemen, thank you all for the prompt responses, I have been Googling for Britain with only very limited success. I think I'm going to have to very carefully measure the screws (there is more than one type) and post that info - cant do it at the moment as away from home.

Also, I want to get exactly the right threads as a number need holes retapped as they've not been loved and for some the thread has almost been obliterated - I'm hoping I can identify the thread from the relevant screw and work from there.

I'll have a look at the companies suggested and see what I can achieve.

Have a great Christmas.

Hi, I'd be grateful for some advice on where to source imperial sized countersunk and socket head screws to replace some rather worn ones on my v old Smart & Brown Model M Mk 1. If I could confidently state what size they are I know that would help, but that too is proving difficult. The smallest is about 5/32 and probably 32 tpi.

Grateful for your thoughts.

Gents,

Many thanks for the comments. I'll follow them all up. 'Old Mart' - an interesting suggestion to use such a light oil, though I can imagine that it certainly gets to where you want it. I obtained a specialist oil for the head bearings which have felts to move it from the reservoirs, but am away from workshop so can't check the spec. I was going to use slideway oil on the leadscrew.

Many thanks all.

Hi Raymond, The personal access is definitely free and allows unlimited numbers of models (a model includes all the parts, assemblies and drawings to make a complete set) so not sure about your '...or if at all..' comment. I checked on the onshape site and the CEO has stated that there is no change to existing pricing plans.

Hopefully my info is correct - I certainly hope so and that things don't change.

All the best.

Hi,

I have an old Smart & Brown Model M Mk which I'm renovating. I'm now stripping down the leader screw gearbox and find two bearings, which are hidden inside the, bed are lubricated via short pipes that lead to 'grease nipples' on the rear of the machine. The bearings are plain 'brass' bearings which I can't believe would be greased. This gives me two questions:

1. Where do I get a manual oil pump with a grease gun fitting? Or even a hand oil pump that does more than dribble the oil out?

2. What oil would you use?

Having taken the end plate of I find it carries a number of gears and wonder what to lubricate them with? The oil from the bearings wouldn't find its way to them and while there's a grease point on the back wall of the chamber there's no way that anything injected there would ever reach the gears unless the chamber should have an oil bath, but there's no site glass and doesn't look as if that's the way it was setup. Grateful for thoughts from all the experts.

Many thanks.

I have a Model M Mk 1, which I'm about 50% through renovating. I'm also drawing it in Onshape as I go, the drawings are all public if you have an account (free). So far I've drawn the headstock and saddle.

Just a thought but why not try Onshape. It's a fully functioned cloud based CAD system built by people who established Solidworks. You can use it for free provided you don't want your models to be private, which to my mind is ideal if your learning cad or just doing it for your own satisfaction.

I'm using it to draw a Smart & Brown Model M Mk1 which I'm renovating. It's a case of I've started so I'll finish.

It's just a thought but saves lots of discussion about costs etc

I've been using Onshape for the last month or so. Just thought I'd correct a couple of things:

Onshape have changed what you can do for free (which is a huge pity). You get the 5GB of total storage, but to do so you have to create the document while you're under the 100Mb Private document limit, and you can have a total of 10 Private documents - I think you can have as many public documents as you like.

Elsewhere it was mentioned that you couldn't print from OS, but it is certainly possible in the version currently in use.

The drawing facility has arrived so that true 2D drawings can be produced from the 3D parts and assemblies.

The thing I like about this is the ability to animate the model, not automatically, but I'm happy dragging the little handles around to watch my Hot Air Engine do its thing - I've even been able to actually explain how it works to my better half!!

Hope this helps.

Just thought, but perhaps it's the fastest machine for a given pressure. In truth I think there will be a range of 'best' builds since we're looking for the most efficient and that could vary for a range of pressures and loads. Would be an interesting experiment.!

Hi Lofty, looks like a great model - the marble base is certainly an improvement on my original casting! I' ve sent a separate message with my e-mail address as I would much appreciate a copy if the plans.

many thanks.

Hi, I know this is an old thread, but I've been searching for this model for ages. I made it for O level Metalwork including casting the base. However it was once in my parents house but has since disappeared. In October I getting a real Manshed built and will install my fathers old lathe and milling machine. I think remaking this project will be a great starter, maybe even casting the base (friend has a forge!). If anyone knows where I can get a copy of the Haynes book 2 I'd be grateful.

thanks
