Wheels more difficult than a boiler?

It must be a good boiler design.

That's very helpful Paul. I always like some 3D to help me understand a part.

Thread: South Bend Heavy Ten Fixed Steady
27/12/2020 11:39:57

cimg9351.jpgMerry Christmas and a happy New Year everyone.

My planned Christmas present from Mrs B was delayed, but fortunately an item I happened to see on Ebay turned up just in time to replace it.
A fixed steady for the South Bend lathe. This is a very rare item in the UK, where these lathes are uncommon to say the least, and an expensive import so this one was worth a punt. In the event this item not only fits perfectly but also works perfectly as well, so I am very pleased. The only point of note is that two of the knurled locking screws have been replaced with brass slotted grub screws, this has happened recently as the screws are bright; I would have thought that they are a bit easy to damage, so I shall seek or make replacements.

This should allow me to machine long shafts and tubes, especially some steel I have that will be good for wheels and rolls for the small traction engines and rollers that I like, I am still crossing my fingers as the diameter that this fitting allows is a bit small. That's what you get with a tool room lathe that assumes that there is a bigger lathe somewhere. The upside is that this casting is very strong and flows metal around the adjusters, which are sublime in action, so it is many times better than the current style of inexpensive lathes that have most of the metal slotted out. Either way this important piece of kit was missing from my machine so it is now complete in that I have a travelling steady, three and four jaw chucks and a taper turning attachment.

Allowing for the chuck I should be able to cope with 500mm long workpieces.

Back to Black is a silicone oil another use is when sprayed on a small piece of cloth and then rubbed on car door seals prevents the doors freezing shut.

Great tip!!

My car used to have a useful seal strip along the bottom of both doors but it froze and got snapped out when I opened the door.

I can now get a new one and prevent a reoccurrence. laugh

And get black stuff on my trousers. blush

Thread: Message from ARC to our customers in the E.U.

secret so many bitten tongues I can almost feel the pain in every post. wink

The main issue for most people seems to be our arrangements with China rather than the EU. I think we are going to have to see how that settles down over the year or two it takes to deal with Covid.

Exporters are up the proverbial creek until we have stable export arrangements and that needs both politics and pandemic to settle down.

So maybe this is the time to invest in restoration equipment, a good sharpener maybe?

Thread: Cutting copper tube square

The reason for not using a pipe cutter is that they dent the end of the pipe, Fine for inserting in plumbing fittings but no good to go round a boiler end plate. OK if the end plate is external though, although that raises the obvious question.

So for an internal end plate the bung method is best.

?? So the clever chappie loses his company and a few years later wins a million with a fantastic and highly marketable product that clearly competes with his old company but with additional world-beating innovation!!

Maybe they should have kept him on?

Real dragon's den stuff, but with some super tech.

Thread: Warco experience - WM18B
21/12/2020 20:58:27

smiley Well I am glad I am not alone with my problems with Warco Products, its good for my sanity, bad news for you lot though.

My e-mail to Roger Warren about my 16B had a section about CE marking in it, but I deleted that as anyone who has sold equipment for so long without worrying about doing that properly isn't going to appreciate a wise-arse.

I never did get the advice about the ticking noise as it rotates or any advice as to the best solution for the safety interlock that conspicuously didn't work when the machine was delivered, but after a week or so of silence I chased up the staff who where very glad to have the extra stuff back that had found its way into my crate and were very helpful about the further issues.

I still consider them a good company to deal with, they do try to make it an easy process, its just that they can't deliver the technical expertise that the world has got used to in other fields because they don't have the design engineers as part of their staff. That said what was your experience last time your car broke down? Most of the times it happens to me the mains dealers are hopeless, they usually have to wait for the "master mechanic" to come in and phone for help.

The 16B is a wonderful machine, I will do a video when I have everything as it should be and I can find all the lubrication points, I think one is under the long-axis DRO scale. I also need to move the short axis scale because it collides with the wall. You get the gist, lots of things to set up and get sorted, little mods to do etc.

ta for all the links angel

Thread: Hacksaw blade orientation - your opinion please

This is an interesting thread as reciprocating mechanical saws are museum pieces now.

As well as lifting the blade on the return stoke some machines have the crank offset to give a quicker return stroke and more power on the cut. I don't know why I think that but I am sure I have noticed it on a real machine somewhere. (Real as opposed to my collection of toy saws.)

It might be fun to experiment with Lego and see how it works.

Maybe I should post part 2 of the video when the LEGO model decides to self destruct. :-|

Yes, do so. Its always fun. wink

You must be right Robert, I guess there is a market.

Interesting that the Warco and Ajax are obviously by the same manufacturer.

My experience was that power hacksaws were being replaced by bandsaws as bandsaws are at least twice as fast for most sections. Even my previous employer, 17 years ago, had moved to bandsaws.

Looking at the Cromwell site bandsaws are a lot cheaper for a similar capacity, but I wonder if they last as long?

Thread: End Mill holder - Help

Hi Me.

I am surprised that there isn't any Morse collets hidden in the tool collection.

In any event a quick sort and survey will help guide your choice of investment. If the majority of tools have standardised diameters then the choice gets easier. Equally if you know you are only going to do small stuff.

Thread: Have You considered getting a 3D printer
12/12/2020 14:55:18

smiley I will be looking hard at them when I am sure the heat resistance is where I need it, and that means stability not just melting temperature. I know that materials with 150-170C are out there now so its pretty close.

Off course metal additive manufacture is available but that costs money as the machines are very expensive.

Generally I am waiting for the technology to make live steam, detailed models fast, for example printing a traction engine wheel set in a weekend rather than slaving for weeks. Those awkward little brackets that you can't see from a couple of feet away etc.

Thread: How does this rotary table bolt down?
06/12/2020 19:54:19

smiley I do like those toe clamps.

I have a large turntable, (missing its worm gear, which is why I have it), that has two featureless pads sticking out the side. I think its simply a clamp-down job. It does seem bizarre. It won't be out for a while, far too much to do. gift

Thread: Supplier for a Drill Chuck Key
04/12/2020 19:44:25

No I was right first time.

Yet another case of the Warco website being wrong about what they ship, in this case not a problem as such, I just need to get something for holes below 3mm for Christmas.

At least type B16 chucks are a common standard.


01/12/2020 22:08:34

13mm! wink

01/12/2020 21:56:27

My new milling machine came with a whopping great chuck, 16mm I think, but it has a very short key, only a couple of inches long, so there is very little leverage and it won't hold a 6mm drill tight enough to stop it slipping. - Useless!

Obviously turning up a handle is the next job, but I suspect that a longer shaft/whatnot will help get the turned handle clear of the chuck.
