It's really difficult to find specs for chucks, but here is one which is fairly good 30u, (0.03mm) but very pricey. They have a selection of other quality as well. Here is a link to some Jacobs stuff I think 0.04mm TIR

It's fun, isn't it. and scary. I didn't have a hoist, so the way I did it on my Meddings was to lay the body on the floor and fit the column to it, then slide the column all the way into the head. Use the column to lift the drill vertical, then get the head up the column. The reverse of how you...

I hope you continue to make a full recovery and finish off removing the asbestos. 😁 I think we all take what we have for granted, but it can be taken away so quickly. You just have to make the most of what you have and try to enjoy life as much as possible, it is great fun. How long until you...

That is an excellent combination unit. Now that I see it in full, the top looks similar, but not the other parts. The saw I have is about the same size, possibly 60 years old. I'll take a picture tomorrow, just for comparison.

It's only when you start delving into these type of things you realise how vague some of the specs are. I'm sure some quote the runout at the spindle, others with something in the chuck.

This is something I haven't looked at in detail before, but I think that is probably typical for a 'normal' chuck Here and here are Rhom chucks. Their best one is 0.05mm concentricity and 158 Euros, but some of the 'Supra' chucks are 0.35 and 85 Euros!

Welcome to the forum :)

I agree and understand your dilemma. That chuck should not give the problems you are seeing, but what else can it be? Interestingly, I don't see any figures for runout, so what they describe as high precision is unknown. I doubt it would cause the problem, but have you tried reseating the...

When I had my business, I used Quick books from Intuit. It was very good. I see they now offer MTD for VAT, but looks like £8/month!!

On my Chinese chuck, the outside is way off, looks like I machined it!! To quote a very famous detective.....When you have eliminated all which is impossible, then whatever remains, however improbable, must be the truth.

Welcome to the forum. When I clicked on your location under your name, it goes to a vegetarian restaurant in Brighton 😁 Are you in New Zealand or a smaller Island? Your workshop looks very well organised. I'm very interested in that cast iron blue saw you have, bottom right corner of the...

I think you have shown that the drill is OK, I think it's very good, which is good news. You have also shown that inexpensive chucks are pretty poor and all three are poor. You need to get a much better quality chuck if you need the precision Out of interest, I did a check on my lathe with a...

I've been confused by how you are measuring and some of the statements you have made. I'm not sure if you think the runout on the spindle was acceptable to you? You measured 0.005 to 0.01mm? are you happy with that? I would be delighted with it. That's 0.2 thou!! The statement that confused me...

Welcome to the forum. I'm miles away as well.

is the table set and is the square square?

My poor explanation. If I could do a image dump from my brain, it would explain better. Util that is available, I'll do a sketch. You could put some feature on top at the corner. I think that can be made. You could put a similar feature on each end.

Welcome to the forum 😁

I thought he was a photographic model to help practice studio photography. Very useful!

What a beautiful model. What an unique gift the MD of the company will get . Do you put a maker's mark on your models?

Yes, I have seen this. It is very good. Must be similar technology used to colour the WW1 film. It's amazing how converting an old B&W film to colour really brings it to life.
