Clarkson Drill point and tap lead grinding attachment

[Milkybars]

I managed to acquire one of these at the weekend..
But it hasn't got any of the indexing collars.

I wonder if anyone has one that they could measure up for me.
They look to come in 4 flavours, one with 2 slots, and then three with 2,3 and 4 pins respectively

Also contacted Steve who runs the excellent site, http://bedroom-workshop.com/index.htm
for a copy of the DPATLGA user manual

I have just acquired a Clarkson tool grinder. I have looked at the bedroom-workshop site but can't look at any of the literature. No means to sign in either.

Milkybars, did you manage to get a copy of the DPATLGA user manual?
And did you get measurements for the indexing collar?

There appears to be no means of registration.

There appears to be no means of registration.

Near the top of page it says you have to email him for the details.

I was having some problems with the email address, Outlook did not like microstock and said domain not recognised. I did have the @ and dot.com in te right place.
However an atempt last night and it has gone, so I am waiting to see.

Does anyone know how to increase the clearance angle?
And does anyone know the purpose of the graduated angle plate that sits at the top of the unit?
This appaers to do nothing, it's movement is restricted by the index plate and it comes off with no apparent conection to anything.

After searching for info on the clarkson Drill point and tap sharpener it would appear that Stephen from bedroom workshop.com has not replied to emails since feb '22.
So I wonder if milkybars could furnish me with a copy.
I would also like to ask if he sorted out the indexing ring on his as I now have one I can make a drawing of.
Also; does anyone know of a source of 16mm Left hand trapizoidal screws and nuts? Or has anyone got an elegant solution to the issue?
My feed screw is seriously worn. Options are to buy a 16X2 feed screw from Igus and make a new bronze nut as their plastic ones don' look like they will fit (clearance problem) which will require me to make a trapizoidal thread form screw for a L/H thread. Or go for a standard L/H metric thread 16X2mm. As I currently have in excess of 1mm backlash anything will be better.

@BitterendThe indexing ring is half done but currently I have zero workshop time or real access
Any images and drawing you could provide would prove my sample to be close would be most useful

Milkybars,
Thanks for the pictures, That makes life a bit easier.
I will remove the indexing ring and do a dimensioned drawing in the next couple of days.
I am currently trying to sort out excessive backlash in the feed screw, trying to find a single start left handed trapizodial lead screw 16mm X 2.5 is impossible, but it could be a 5/8 X 10TPI acme screw, which I think is more likley. However those are also as rare as hens teeth!

I can get a 5/8 L/H acme tap to make a new nut and I think I will have to make the screw.

The indexing ring drawing. I have to make a 4 stop indexing rings
