Has anyone any experience of taking apart one of the Taylor Hobson pantograph engraving spindles, D model type ? I can’t figure out where to begin. Also i’m looking for the collet holding version if anyone has one lying around unused. Thanks.

Downloadable as PDF

... An exemplary design for a high-speed spindle.

Mark, i’ve seen this, overpriced I think and incomplete missing the closing nut and vertical adjustment wheel amongst other things.

Michael, many thanks for the link. This makes things a lot clearer. I understand getting the top bearings out is ok but after that ? There was some info. on a engraving forum but all the instructions and pictures have disappeared frustratingly.....

Thankyou to you both.

Espace.net made me fill in about seven different Captchas and still woudln't share it's secrets with me

Ironically it said the captcha was because I had done too many downloads too quickly (I only tried to do one!) then whatever numbers I used it rejected me. I feel persecuted!

Not sure why you would want to strip one down but they are not really user repairable. The bottom bearing is made as part of the shaft with the inner ring machined as one with the central part and the outer ring as one with the belt pulley. Between the two is a complete compliment of steel balls with no cage. The bearings were greased using a special type. If the spindle is damaged i.e bent it is nearly impossible to do anything with it. If the balls are worn then you will find the inner and outer ring will also be damaged. If there are balls missing then these can be replaced but you will probably find the spindle runs eccentric especially at the higher speeds necessary for fine engraving. Finally the end float adjustment is obtained by careful tightening of the internal screwed parts of which there are a number.

Taylor Hobson used to offer a service repair but obviously this isn't available any more. However Pantograph services employ a number of ex Taylor Hobson people who should be able to help at a price. Unless you can be sure of the provenance of the parts offered on eBay there is a large risk of getting a dodgy unit and I personally would be wary of obtaining one from this route.

I don't think the spindle from a K type machine fits the D machine. But the A,C and D machines all take the same type.

I must admit Captcha's are one of my pet hates and some of the hoops and puzzles you have to jump through are hilarious.

You can still buy or get the spindles overhauled. Pantograph services do it. Not cheap as the prices arent given for a new spindle but around £160 for the overhaul.

Sorry didnt see your mention of pantograph services.smiley

There is a forum for pantograph engravers, you might try your enquiry there.
