Thread: Griptru chucks
27/03/2021 16:49:05

Thank you all.

Just a quick question on Pratt Burnerd Griptru chucks, or the equivalent

Are they worth the expence if you already have decent three jaw, four jaw and collet chucks?

Having three ajustment screws, are they any more difficult to accurately centre than a four jaw with it's two pairs of opposing ajustment screws?

Thanks in advance


Thread: Boxford max useable Chuck size
15/03/2021 08:25:11

A 125mm three jaw with external jaws will easily take an 80mm workpiece, the jaws won't even overhang the chuck body.

Assuming you have the 4.5" Boxford, I personally wouldn't buy a chuck any larger than 160mm though it could take a little larger. (A 160mm chuck has about 50mm clearence between the body and the ways)

Chronos have a Soba four jaw self centering chuck on their website which comes with internal and external jaws and is already fitted with a Boxford backplate so hopefully no machining needed. I've no experience of this chuck but I've no complaints of Soba equipment I have owned in the past.

I've not checked but I think other suppliers aslo stock Boxford specific chucks.

Thread: Boxford AUD head refurbish

You could try Mark Lord at

He specialises in Boxfords and can certainly supply most spares. I think he also does repairs and refurbs.

Failing that, Google 'boxford user group' and join that forum. Someone there will know where to get it done or instruct you on how to DIY.

Thread: Boxford STS Screwcutting Clutch
12/02/2021 19:12:32

Ah, that makes sense. I wasn't thinking along those lines at all. Now I want one!

Thank you.

I'm gong to ask what may be a stupid question, but what is a screwcutting clutch for? I understand how usefull a clutch might be when surfacing but I thought when screw cutting the leadscrew and spindle mesh should be fixed with no possibility of any slip.

Don't forget, ebay do 'sell for a pound' or 'no seller fees' offers every two or three weeks. I use these offers to sell and it's saved me many hundreds of pounds over the last couple of years. You do need to click on the link on either the front page or in the email they send you and list the item on the dates specified, but they're the only conditions.

Yes, you are right, sorry, trying to do it from memory!

If your lathe is metric the screw gear is 50T. If it is imperial it's 40T. I'm guessing your lathe is imperial and you probably have both 40T and the 50T. The 50T can be swapped with the 20T idler to get the full range of standard threads.

Thread: What lathe
22/01/2021 19:14:57

Pre Charged Pneumatic (PCP) airguns are 'hurt your ears and do permanent damage' loud without a moderator. It's thevery reason I started learning to use a lathe.

22/01/2021 18:49:58

That don't sound right, there's no need to use a stop.

If you are not using a TDI and not using the machines reverse to get back to the start you have no chance of decent threads.

Sound more likely user error than duff machinery.

Thread: Running a 3phase at home
22/01/2021 18:24:41

If you are just making the odd part for air rifles, a three phase supply is not really practicle.

I initially ran my 3 phase Boxford via a rotary converter, which meant there was no need to alter the wiring on the lathe at all and if the need arose, I could run other three phase machines from the same converter.

I still have the converter but went over to using an inverter. A cheap inverter plus a control box can convert the lathe to single phase for about £60, if you are competent enough to do it yourself.

My lathe now uses the original switchgear, plus a pot, one additional switch and a relay circuit to give variable speed, electronic forward and reverse, slow speed jog and braking. All the interlocks can be wired in simply enough to maintain the safety features.

Thread: Yet another scam lathe sale on ebay to be aware of

DMB, he will either block you, ignore you or arrange a meeting with you. Then what??

11/01/2021 19:35:08

I sold that Boxford a couple of months back. He has copied my ad and photographs vebatim, so definately a scam, again.

The more of us report him, the better.

John, there is no, "neck of the woods" He won't be based there, he could be based anywhere, abroad even.

Thread: Lathe Milling Machine Help Needed

Lathe looks to me (from memory) to be the same as a Warco 918 or Chester 920, presumably sold in other guises as well. Better chance someone will have a manual for one of those.

Looks like enough people have reported him. eBay have removed his listings. Keep your eye out, he'll be back soon with a new Monica..

Yes, definate scam. All the usual with plagerised ads from genuine sellers. See his other items also.

Carefull. ALL ebay ads default to 'returns not accepted'. His are auctions with low start prices, so not selling cheap. They are seven day listings. He is not suggesting any form of unreturnable payment. He is not based out of the way and he does accept paypal. The only thing he is a new seller but that doesn't automatically mean it's a scam. If paying by paypal you are protected. Paypal won't immediatly release funds to new users, they hold on to the money a couple of weeks just to make sure. Buy from him and either collect or pay with paypal and you should be ok.

He has 2 identical m/c's for sale at different prices? Feedback is old also & a bit strange??


Give them a ring tel deleted

Simply ringing the numbert he' has given you in the ad won't tell you much unless you expect scammers to cave in as soon as you ask if an item is legit.. Calling then asking them to call you back via a land line would help. Anyone can do basic checks of a land line number and genuine sellers won't mind, after all this lathe is being sold by a business seller so they will have a landline.

You could for also check this seller by Googling the company and contacting them via their website (not foolproof but pretty good) and as a business, you could probably pay them with a credit card, which is much the safest way to pay, where possible.

To be honest, this item doesn't raise my suspisions in the way Boxford man did.

I did not start this thread to put anyone off ebay. It is a fantastic resource if used sensibly. I've bought and sold literally thousands of times with only minor issues. I've also bought or sold perhaps 20 items in the £1k - £2k range unseen with no real problem. (Sellers being a little economical with the descriptions of condition is as bad as it gets).

I was a police officer most of my working life. Like most police officers I can be overly suspisious and cynical and I don't believe in coincidence!

A new seller selling a high value item is not in itself a reason not to buy but with all the other contra indicators; recent feedback for low value items, short duration auctions with the item in a remote location (How many people reading could get to Dunoon to view within the time constraints of a 24 hour auction?) BACS as payment, refusal to accept paypal and the biggest one, plagerised description and photos.

Ask the seller an awkward question or for a photo of an obscure part, something he won't be able to get from the net, say, the underside of the tail stock. A genuine seller won't mind. I've run down the garden to my workshop in the middle of the night with a camera and tape measure in order to answer questions before now.

All that being said, I've had some real bargains from new sellers, just be carefull, go with your head not your heart. If it lookslike a duck, waddles like a duck and quacks like a duck, it's probably a duck.
