Dickson type T00 toolholders

Following the demise of the small Coventry firm that manufactured good quality toolposts and holders, a new source has appeared on "The Bay", item number 112020207224. This firm is also situated on the outskirts of Coventry.

I have no connection to this new source but was a very satisfied customer of the previous one.

Apologies for my inability to post a better link to the item, but hope it will be of interest to some members.

Well spotted Gordon!

Do we think this is a resurrected A&R Precision then?

It seems that the holders are now blackened which is a bit of a departure but if they fit who cares.

Having tried a few toolholders from different suppliers, including SOBA from Chronos and the official Myford ones, my A&R variants are by far the best in terms of height clearance for stiffer & deeper tooling.

Well spotted indeed, I have been thinking about getting some more holders for a while and have just been on ebay to buy a pair of these to check them out. If they are a good fit for my toolpost I will get more ,although the present listing says there are only 5 pairs left (well 4 now I have mine! ) but with any luck they will list more in future.

The listed ones are the size I need for a Myford Speed 10 but may be too small for some users. The price is very reasonable compared to other suppliers and if they are well made they are a real bargain. I will report back once I have received them.

The name is familiar, but due to a computer crash I have lost correspondence I had with A & R Precision.

The description is the same as used before, and is still erroneous. These are not the size for a Boxford toolpost.

According to Companies House, A&R Precision Ltd went into liquidation in July 2015 (Director: Daren Lynam)

and Lynam Engineering Ltd was incorporated in May 2015 (Director: Daren Lynam).

Jon

Hope he is in production and this isn't just 'old stock' from the liquidation.

I run a Myford size on a Boxford and it is fine for normal work and makes the holders cheaper. I was sold it at the Sandown show years ago as Boxford one and don't know if it was a deliberate downsizing to make a show offer price or a mistake in handing over the wrong one. Didn't have anything to compare it with until so not aware until I came to get more holders.

My second hand Myford S7 came with a Dickson type toolholder. I have since bought quite a few toolholders from Soba, Chronos etc but all have the limitation that I can only use 8mm tooling. When such tools are used there is less than 2mm horizontal clearance between the toolpost flat on the compound slide and the bottom of the toolholder. This means that it is impossible to get 10mm tool on centre height.

I did inherit a parting tool holder which has a rebate across the toolholder base presumably because of this limitation but all my other holders are far too hard for this treatment.

Has anyone found a solution to this problem?

I would try the toolholders linked to by the OP (Only 4 off available now though).

I bought my original toolholders and QCTP set from A&R Precision and find I can use 10mm tooling easily on my ML7.

Since then I've bought the SOBA toolholders from Chronos and toolholders from Myford and these have a thicker lower shelf. I can just about use 3/8" tooling in the Myford ones but can confirm your findings about the Soba ones andthey are now only used for boring bars with lower cutting edges.

I'll try and find the original threads where this issue was discussed.

Just received the toolholders from Lynam Engineering as listed on ebay. They are very nicely made with a black finish apart from the mating surfaces which have been ground. They are a perfect fit on my toolpost and I'm very pleased with them. They are UK made and the quality shows. I had thought of making some myself but there is a lot of work involved and they would never be as good and hardening would be a problem.

When I got my original toolholders I got fed up with the mess the screws were making on the top of my homemade carbide insert tools, which were not hardened. I inserted brass pads into the ends of the screws and this made all the difference. HSS tools would not be a problem but when I started using carbide tips a good few years ago the tip holders were very expensive so the DIY route was worthwhile.

Doug

My Boxford uses the same tool holders as per Myford but the tool post has a plate attached some how to the bottom. It was made by Myford. The plate is around 10mm thick. It's all looks to be ground all over. Only problem really is that the holders wont accept 16mm boring bars. One could be designed to do that easily though.

John thanks for pointing that out. I should have mentioned I have a plate too, about 3/16 which was what fell to hand at the time.

I wonder if ME could find out more about this chap and do a one pager. Any British mfr of tools should be of interest to the readership. It might be nice to see if he has the equipment to branch out into other sizes and the other types of holder ie for piston/wedge type.

I'm pretty sure the plate on mine came with it on from Myford. I've always wondered if they did some heftier tool holders for it. I suspect it may have been produced for the 254.

At some point I will probably modify a standard 1/2" parting off blade holder to take a larger boring bars. It should be just a case of making a sort of bolt on block with groove to take a larger bar. I'd guess it may be possible to go up to 25mm on a Boxford. 16mm wouldn't be a problem at all as that nearly fits the usual size of tool holder.

Thank you Gordon A, I have just received two excellent toolholders from Lynham Engineering, the fit and finish is, in my opinion better than the "foreign" clones I have bought in the past to fit my genuine Myford toolpost.

Paul

Well spotted - thank you! I have just bought a couple of these from the link. I have had toolholders from A and R in the past and they were absolutely first class. It is very satisfying to be able to support firms making stuff in the UK.

Mine fit OK, the lower disc of the height adjuster is marginally too thick, but that is not a problem. I do not care if the blacking is removed.

Definately new "A&R", even Sally still works there!

Street View their address and you see....unit 3 = A&R Engineering on the old google street view pictures

Thank you all for your feedback, spotted them during one of my many idle moments!

Gordon.

Can you post or PM a link to where you brought the tool holders from please. Thanks, Neil Lickfold
