Thread: Hand or Machine Reamers?

Thanks Michael & Andrew Silly Old..., Ah great, that answers that then, more thinking to do, much appreciate your inputs on this!

Cheers

Thread: What motor pulley size for ML1 Lathe?
04/10/2019 12:14:37

Hi Michael & Pete, thanks for that.

Ok, I have a vee pulley for the motor already + new to me old 8" flat belt pulley on the countershaft.

Can I use a vee belt between them then? Sorry if i'm being dense!

But I still have no idea of what size.....

04/10/2019 11:59:41

Thanks Michael, having just bought the 8" Myford FLAT belt pulley I wish to use a flat belt between it and the motor.

Its the size Id like guidance on and can I use brass if I choose to?

I appreciate a vee belt system is likely easier to set up but i'm looking to set the lathe up nearer to the original look.

Cheers.

Thread: Hand or Machine Reamers?
04/10/2019 11:44:25

Whats the difference between hand & machine reamers?

Having searched online I see plenty of both, the difference I can see is hand reamers have the square on the end to fit a tap holder.

I'm looking to buy some, maybe Dormer to help with work on a Stuart James Coombes.

I'm thinking if I buy hand reamers I can also use these in the lathe Myford ML1

& pillar drill at slow speeds. Am I missing something?

Thanks...

Thread: What motor pulley size for ML1 Lathe?
04/10/2019 11:37:37

I have an electric motor 1425 RPM on the plate. An 8" dia flat belt pulley on the Myford bench top motor stand/counter shaft. Then flat belt pulleys from this to the 1930's ML1 that I am trying to resurrect and get going.

Looks like I will need to make a flat belt pulley for the motor, advise on what size should it be please? (I don't wish to change to vee belts).

Any reason the pulley should not be made of brass?

Thanks in advance.

Thread: Die filers for beginners?
30/08/2019 22:42:16

Yes thank you KWIL, I think I saw that they do.....

30/08/2019 21:51:16

Thank you Dave, more as a useful bit of kit than an exercise I think. If a ready made Martin M version turned up I'd have it. I could have used one for work this week!

Both are interesting links, though neither work for me. Yes I'm aware of the shipping and import duty and as you say if I mess up.......

I will keep on pondering! (-: I may order the drawings only to see what exactly is involved.

Cheers

Thanks Brian, yes I'd seen that, for me on aesthetic grounds its if all else fails, I'd much rather have castings (-:

30/08/2019 17:27:38

Thank you ega, yes I did mean the sawing & filing attachment. I have emailed them this afternoon but would also like views from anybody who has built one, and is cast iron (rather than mild steel )so important for a small machines table such as this.

30/08/2019 16:21:46

Good afternoon, can anybody help at all with my last posting, copied below?

Hi all, Ive been looking at the Martin Model and Hemingway die filer kits as a potential first project on my Myford ML1, that has 3-1/8" centre height. I have a vertical slide for it but I don't have a seperate mill..I do have a decent size bench drill. Oh and I'm a beginner.

Putting aside the table which I figure I could fabricate from mild steel (is cast iron better for machine tables such as this?) I'm wondering if I have the size capacity to make one up???

I prefer the look of the Martin model but for some reason figure the Hemingway might be the way to go.

Could any makers of either of these two please comment?

Many thanks

Chris.

Thread: Using a pillar drill for milling?

Thanks Neil, I've ordered some books and past ME issue CD'S and will take some time to process what's next.

Thank you Nick, Dave, Not done it and NG2 I will investigate further.

In terms of my work I'm used to BA, BSB & Whitworth threads, though I normally use metric drills. I find most of my raw material suppliers still supply Imperial sizes. But measuring myself anything under 1mm my metric digital calipers come into their own...referal to conversion charts for drill sizes etc is frequent.

My lathe the old Myford ML1 was bought on grounds of size, ie small, basic, and looks, I like old tools & machinery. I am gradually learning the basics of how a lathe works and what does what, not that its running yet. Before buying I was aware a ML10 or ML7 is much more sophisticated and up to date but I felt it better to start basic. Someone mentioned Drummond treadle lathes I think, I was SO tempted but being tall I figured I'd bang my knees and maybe that was a step back in time too far, oh and space was against it too, I can store stuff under the Myford.

Apart from the general ability to turn steel (I hand turn brass on my wood lathe) the aim for me is to be able to make a stationary engine kit such as a Stuart Turner James Coombes. I started one years ago and put it down when self employment work took over. By started I mean I did some basic work like chain drilling and cutting out apertures in the plate steel, filing up castings and taper turned the 4 columns on my Unimat SL. Leaving the tricky stuff....

A few years back I gave it away to a relative to finish but hes not touched it so I might be able to get it back, if I don't I'd like to build something like the Polly Benson engine kit. But I don't have a mill and can see a dedicated machine would be better than trying it on my basic lathe. So I then looked at German Bengs kits, as they don't need milling, its already done. But they use metric threads of which I have very few, though I guess I could use imperial.

I expect the S Turner kits specify any milling required in imperial but I don't recall? That why I asked about metric or imperial, in a nutshell wink

Cheers

Chris.

Regarding the milling, also metric or imperial??? I'd probably find metric easier to get my head around than fractions of an inch, but would be interested in your thoughts?

Cheers

Thank you Nigel G2. Well if I want one it looks like it will be imported and small, I only have one available place for it and that's at one end of my workbench. Whist the bench is substantial I take on what you say about rigidity etc but I'm restricted to the bench only. My drill is a bench top model. Yes I had looked at the BCA's and agree it sounds like its not ideal for me. Yes I was looking at Warco's offerings, I could get to their showroom ok to see first them hand. Looks like machine size will more determine what I can and cannot take on to mill, but I have to start somewhere. Having a modest capability rather than none will help guide me as to what I want to end up machining, most likely stationary engine kit/s. I wont be rushing into buying that's for sure.

So I had to look up what DRO meant, ....as its available on new machines is it now considered a must have?
On the down side it adds around a third to the cost of the small machines and is no doubt another thing to go wrong.

That said I didn't want digital calipers as I knew the batteries would run out and they would likely go wrong...Well I was right but that, but I'm so grateful I can see the display to read what I'm measuring!!!! (-:

So maybe the same holds true for DRO?

Cheers

Thank you Bill & Silly Old Duffer, seems like I'll have little choice but to go Chinese, still think its a shame though.

Cheers

Thanks Neil, oh ok, add that to the rest of the stuff I didnt know! (-:

Cheers

Hi Silly Old Duffer and thank you. I just looked online and at least I dont think I made a mistake buying the ER20 collet set, I dont think the ER32's are available on a 1MT, that would fit my lathe. Actually I have a Tyme Cub woodworking lathe also that they fit, I do my freehand brass turning on this, and cutting threads using taps & dies. But now at least I know a little more of the various types and can take that into consideration when considering Mills.

Cheers

Chris.

26/06/2019 14:34:57

Thank you not done it yet, yes I figured there would likely be a compromise somewhere along the line, appreciate you point out what it is. I'm thinking buy a mill in due course to replace the drill, but put the drill in my other workshop. Its not i'm sure ideal but at least then I'd have the height available to drill holes at least.

Out of interest what make of mills do you have? In due course I'd much rather buy British if I can, even if it has to be second hand....

Cheers

Chris.
