Thread: Tap and Die

I have drawn a blank on that size - perhaps it is a special. These people will make specials in 24 hours but I suspect the price will make your eyes water.



Thread: Anyone recognize this?
27/03/2019 09:15:55

I built one of these forty years ago from a set of castings that were advertised as for a "sensitive drill". The foundry was somewhere in Lincolnshire.


Thread: Collet Chuck or not ?
26/03/2019 11:19:54

The thing about ER collets in particular is their versatility. Yes they are very handy for holding milling cutters both imperial and metric but they are also indispensable for holding finished machined surfaces on materials like PB, gunmetal, brass etc. without leaving marks.

In my case I originally bought ER25 but since then I have upsized my lathe. So in order take advantage of its larger capacity I had to choose between ER40 and 5C. I decided on 5C simply because a cheap job lot of new collets became available. I still use the ER25's on my WM16 mill and very accurate they are - am I allowed to say they came from RDG?

"Heaven help the Fusion 360 users if Autodesk pull the same stunt"

Just a matter of time I suppose. Sooner or later they are going to want some cash from you. Can't blame them - they are not a charity.

I also got the message. I've deleted with win 10 uninstaller but ioUninstaller reported lots of rubbish left behind and it very kindly deleted it all for me. Glad I did not invest to much time in THAT one.

Thread: cutting the bar of a digital calliper
24/03/2019 18:14:12

I cut WARCO supplied DRO scales with an abrasive disk in an angle grinder on a stand after finding that my best hacksaw blades would not look at them. I have been using IKEA 2032 lithium cells for the xy readout and they go flat in no time. 4 sets of two in 12 months crying 2


Thread: Making split bronze bearings [ silver soldering ]
23/03/2019 11:20:12

Quite understand what you are saying Jason and I understand that not all crankshafts are equal. However, and as you point out, the DT design does allow for solid journals. My only other engine also had journals from solid. Maybe I'll try another model in the future with the split variety but until then it will remain a "pleasure" to come.

For historical accuracy split brasses are a nice touch but I will make mine differently. I shortly need to make 4x PB journals for the crankshaft on my current Double Tangye in progress. They will be made from solid bar, no splits, no soldering! The feed spigot on the oil cups will stop them rotating.

The only splits found on this model are between the CI standards and journal caps. The completed journals will be slid onto the crankshaft then the standard caps will be fitted holding the crankshaft in position.

Dave - I usually buy a box or two when either Aldi or Lidl have them in. I have not seen any lately though. To be sure, they are not as good as something like Unbrako but they are quite acceptable for much of what I do in the workshop. I would not use them though on safety critical fittings - on a motor bike for instance.


Thread: I want one!

"You'll be wanting a rat for that"

Rats only do files of small tail types I'm told

But in practice these vermin keep learning

They always start small but as they get old

A big bastard ratty is yearning.

Thread: Doncaster ME show 2019
17/03/2019 10:05:35

Lots of useful pointers chaps - thank you. We have only booked for two nights at our hotel near Bakewell so will fit in whatever time allows.

Since the expo at Sandown ground to a halt some years ago crying (my wife loved going there) we have just stuck with the Midlands show at the Fosse Way simply because its not so far from us in North Bucks.

However, this year I have bought tickets for the Doncaster ME "do" and we'll stop a few days and explore the Peak District as well.

So, for those who have been to both events in the past how do the two compare?

Thread: Soba rotary table

I bought a WARCO 6" couple of years ago. Does that make it a SOBA or VERTEX?

Thread: Lathe screwcutting
11/03/2019 10:51:43

Plasma - I have a lot of small section HSS and made this holder for it. It gets used a lot primarily because its less time consuming to form a tool in small stuff. To give an idea of size the HSS bit in place is 3/16" square



Thread: MT4.5 sleeve

Your rotational speed will need to be at the lower end of your suggested range- say 40-100 rpm. Between centres is OK. Don't forget to have the work rotating the opposite way to the wheel. Even if I was doing this on a proper cylindrical grinder in the days when it earned me a crust ,I would not dream of doing it without flood coolant.

Rather than go to all that trouble, have you thought of using a carbide tool and just turning it down - its how I would do it! Good luck anyway.

Bob this should help.



Thread: Lathe bed regrinding
08/03/2019 12:46:01

Hello Barnabas - You may not to tie yourself down to grinding alone - my ancient Grayson flat bed was flycut on a SIP jig borer many years ago. It made a lovely job of it! I would add that the bed was close grained cast iron and unhardened. The bloke who did it for me said it was the best cast iron he had ever machined.

If you want to register as a student with Autocad Mechanical you get 3 years FREE access to the package - why pay?

"My wife thinks I'm loosing it"

My wife agrees with her laugh. Enjoy yourself Martin.


Thread: WARCO spindle bore
23/02/2019 09:21:33

I used to own a WARCO WM-250 v-f lathe (the older non-inverter version) which I moved on some time ago. I was just going through some bits I had made for it and noticed that my shop made spindle stop for it is 28mm diameter. Out of curiosity I googled aforementioned spindle bore dia. but everything that came up for all variations of the WM-250 that I could find returned 26mm - without exception!

I had used the stop many times so I know I am not dreaming.

Any ideas?
