Burnerd Miniature Quick-set Toolpost Type TP

Has anybody come across a Burnerd Miniature Quick-set Toolpost Type TP2?

I have attached a picture of it, other pictures of it and tool holders etc. are shown in Kens Album

Interested in any information or ME. or MEW. articles on it it.

.

I'm afraid not, Ken ... But having seen your pictures; I want one !!

Ken,

I was about to suggest viewing the lathes.co.uk page: **LINK**

http://www.lathes.co.uk/burnerd-quick-set-toolpost-type-tp/

... but the similarity between those pictures and yours suggests it might be fruitless.

I wonder how well they worked with the tool bits sandwiched between two pairs of grub screws and the working end of the tool holder resting on an Inverted V? Both would seem to suggest a less than rigid setup.

Also don't look as easy to set tool height as a good QCTP as you would have to fiddle with grub screws from below.

Unless I'm missing something that makes the set desirable apart from the name.

It looks to me as if the inverted vee is just to prevent lateral slippage and that the flat rests on the base (?) but the four grub screws holding a toolbit would be a real PITA to adjust. Forget milking stools, this is more like an inverted pendulum

What's with the so-called form-tool? That round slug looks more like a crude bearing alignment tool to me.

My honest opinion?

I think that device explains why Burnerd are known for their chucks, not their tool holders...

Interesting note on Burnerd's origins, here: **LINK**

Sorry about the length of the URL ^^^

The opposed grub screws would, theoretically, make it unnecessary to use shims to set tool height. Jason and Jon seem to have pretty well covered the (im)practicality of adjustment on the machine. Only easy way I can see is to have a separate setting jig on the bench incorporating the Vee and pin mounting surfaces on a body suitably cut away for access to the grub screws. A vertical arrangement looks to best way of doing such.

Jon that round slug is a piece of tool steel to be ground as the user sees fit.

Yet another tool-holding system that stimulates my inner McEnroe "You cannot be serious.". Gotta be something about lathe tool holding that interferes with normal engineering sensibility.

Clive.

Thanks Clive. I'm reminded of those round 60 degree threading snails but I guess you need to grind your own cutting edge and profile then.

Jon

That little red printed nameplate on the toolpost .... what do you call them and where do you get them made ? Anyone know ?

Jon

By 60 degree threading snails do you mean the simple single point versions (Denford, Andycraft et al) or the proper full thread form chaser systems (C E Johanesson, Dormer, SKF). Both have / had 55° (Whitworth) and 60° thread-form versions.

I have both types in both thread forms. Got most of the Whitworth and UN threads in the Johanesson / SKF / Dormer system but can't find metric ones. Certainly my preferred method of external threading if I've not got Coventry die head chasers in the right size. Internal ones look to be very rare. Only got 3.

Clive.

Clive,

I was thinking of the type second from the bottom here...

I have to admit I've never seen one in the flesh.

Jon

Ah, a pirate copy of one of our magazines

Interesting that they appear to be grinding the outside of chuck jaws, with them half-open! Perhaps there is something inside the chuck body?

Well at least it provoked interest and conversation!

It appears to have been well used judging by the amount of swarf in the tool holders.

I was thinking of making replaceable tip tool holders fit. once set it would be a just a matter of replacing the tips as required.

Ken,

The first picture on the lathes.co.uk page includes the patent number, but it's not legible [to these tired old eyes, at least] ... Could you please check and let me know.

Many thanks

Looks like it should belong in the "can opener"thread!

Little red nameplates, I used to get our company injection mould tools nameplates done in Birmingham. I will look up the name when next in the workshop, doubt if they are still in business though. Try google nameplates a lot of places doing repro stuff for car under bonnet info plates.

Hello Ken,

My George Adams round-bed lathe has this toolpost system - I've been using it for nearly 40 years and wouldn't change it for the world.

Steve,

If it's convenient, could you please check that patent number for me ?

MichaelG.

I'll have a look tonight Michael.

Best regards
Steve
