2011 forum posts	Can anyone suggest a source for a new belt for my lathe? lathe is a Chester DB8, 3 yrs. old,direct belt drive, ie. not speed controlled motor. Belt is non standard. 15mm wide toothed belt, made from polyurethane ? Tooth pitch measured with steel rule is about 4.5mm, tooth width about 1.5mm. No. of teeth124 (more will be OK) length outside belt 560 mm.thickness over teeth 2mm. I can't find anything on the web, tried all the belt suppliers. Maybe some other machine uses this belt. Other approach will be convert to a standard belt and pulleys, any one done this? Will be difficult as will only have high range speeds.

A few minutes' research reveals that if this is a DB8V, then according to the Chester forum the belt that fits it is a Gates 7M710, and they can be picked up from several different firms, rather more cheaply than I suspect that Chester would supply it... I found that here, FWIW. But if it isn't the correct one, then clearly Chester is the right place to turn first, like Roy says. Getting the spec of the belt appears to be the thing to do though - shopping around looks like the way to go. Edited By Steve Garnett on 03/12/2010 12:39:54

2011 forum posts	Thanks for replies so far. Yes I asked Chester first, they can't help, which is why I posted here. It's the toothed belt I need , like a minature timing belt, although the V belt is not a common size I found one OK. It would help if I can find the belt standard, if there is one.

1946 forum posts 179 photos	hi Gordon, If that's their customer service, i.e. can't supply spares for the equipment they supply, I think that I'll go elsewhere for my new machinery. I thought they would have had an obligation to keep spares especially ones which are liable to need replacing such as belts. No wonder Britain is going down the pan. Do Grizzly or Harbor Freight in the States do an equivalent, they would probably be faster and cheaper. If Grizzly do an equivalent then there will be a manual and parts lists on their site. A much more professional approach, I wish they traded here. Terry

Warco one sare likely to be the same, I know my 280 has a similar Polyflex belt. One thing I do with a new machine is note the belt ref that is printed on the belt as it can wear off with use. J EDIT just read your post again its not the variable speed one so the 7m710 is not what you need Edited By JasonB on 03/12/2010 17:59:23

424 forum posts 98 photos	Well if Chester can't supply a toothed belt then I'm in trouble, I've got a variable speed Comet and that has a toothed belt as well. It seems inconceivable that they don't stock such a basic spare. Roy

157 forum posts 4 photos	Greetings Gordon. I had a similar problem about 5 years ago with an Axminster "Hobby 818" lathe that used a very narrow Gates belt of vee form. My solution was to take the belt to various local suppliers of belts and bearings etc. Eventually found a helpful young man who took the trouble to take measurements and delve into the catalogues, I think it may have been at BSL or Brammer, (they may be the same company). Took a couple of weeks to arrive and cost about £13 for a pair. (1 as a spare). Could you do a similar thing? I suppose I am lucky that there are still some vestiges of engineering here in the (de)industrialised West Midlands. Hope you have similar opportunities. Gordon.

940 forum posts 30 photos	Hi Would the round belt material that you make up to length be suitable. It is or has been advertised on Ebay. I think the process is to measure round the pulleys to determine belt length then subtract a bit (set percentage) and join using a hot blade. I realise that is not suitable for a flat toothed belt replacement but could work on V pulleys. I think it has been covered on this forum before so may be worth a search if the lathe supplier fails to stock the spare you require. Cheers Martin PS Terry I would agree with you that the supplier should be obligated to keep what is effectively a consumable for a reasonable time. Even if not obligated then good customer service would dictate that spares like this should be held . I know for a fact Chester don't/won't hold touch up paint for their machines.

25215 forum posts 3105 photos 1 articles	Just read something similar on CNCzone. Could it be 3/16" pitch in which case its a "F profile" belt and virtually unobtainable, the profile dates from the 50s & 60s and does not match the current imperial (XL)or metric (T5) pitches, maybe the far eastern factory has a stock of old belts to use up or the mandrel to make them Jason Edited By JasonB on 03/12/2010 20:11:17

25215 forum posts 3105 photos 1 articles	Looks like Quantum do the same lathe in both variable and 6 speed like yours, may be worth contacting them for spares, I think in germany they have to make spares available for a set length of time, I know I wa sable to get a spare belt for my Emco that was 20yrs out of production.

1946 forum posts 179 photos	Hi Gordon, I just had a look at the Grizzly G602 which looks to be the same as the Chester DB-10 a slightly larger version of yours (I think) the parts list shows a toothed belt. It may be worth an email to check. Apparently according to the WTA the current legal position on spares is this: "Legal Position Manufacturers or distributors have no legal responsibility to supply spares within a given time frame. Current EU guidance is that, if a product costs more than £125 at point of sale then functional spare parts should be available for eight years from the date of final production. For cosmetic spare parts this period is six years. There is no guarantee of spares availability or any guarantee on how quickly spares have to be provided within or outside of this period Functional spare parts are considered to be any mechanical or electro-mechanical part." It may be worth pointing out the EU guidance to Chester as an example of good customer service if not legal requirement. Regards Terry Edited By Terryd on 04/12/2010 03:10:01

Ian S C 1/16" x 3/16" x length of belt Edited By Ian S C on 04/12/2010 00:51:49 UK suppliers do keep imperial belts but as I said above the current imperial (international) standard is not 3/16" pitch, the nearest is termed XL which has a 0.200" Pitch and these are not made 15mm wide, 1/2" or 3/4" are the standard widths.

2011 forum posts	Thanks for all the replies. The F section seems a possible , will try to track it down, can't find any ref. anywhere. Tried hawking the belt around, very limited round here unless it fits a tractor. Belt is still just usable, so will look into getting pullies and belt for metric HTD range and make the mods .if possible . Chester ignored emails, the man that deals with these things is busy in the workshop, and doesn't reply to tel. calls, ( thats a quote ) This was made in 2006 so hardly old.

1531 forum posts 44 photos	Gordon A, I'm intrigued about your Axminster 818 lathe and the narrow belt. Is this lathe the same as the Mashstroy C218T (refer to Mashstroy on Lathes.co.uk for a picture)? If so, then like you, I used BSL/Brammer 2 weeks ago to get replacement belts. I hace the Warco 220 version, but I know Excel did sell the same lathe as the Excel 818. On a more general basis, I have found in the past that BSL (as it was) have been very helpful indeed in obtaining and supplying drive belts, eg, it took three attempts to get the correct size for my drilling machine primarily because the old one was stretched too far. Regards, Peter G. Shaw

1946 forum posts 179 photos	Hi Gordon W, I'm quite disappointed that you seem to have ignored my email about the Grizzly G602 (also produced since 2006by the way) which appears to be the same as the Chester 10B which is the next size to your lathe. The countershaft and drive belt also appear to be similar if not the same. They even illustrate the parts in their parts list and will ship parts to the UK for postal charges and you can order them from the website. It would have been at least worth an email or just contact them from their siteto see if the the belt would match but it appears that you think it easier to and possibly cheaper to modify the machine with new pulleys and belts. I assume that the toothed belts and pulleys were originally used to provide a positive correlation of the drive when threading which vee belts will not do. Still it's your choice.

9 forum posts	Hi Gordon, Not seen the lathe, so not really sure what I'm talking about!! Two suggestions look on the Radio Spares web site they do lots of odd sizes in lots of things none electrical, second suggestion if all else fails check on the HPC Gears web site, they might have the belt you need, if not they could supply a belt and pulleys to convert to a stocked size if you have any room to change pulleys and tension motor etc, as I said I have not seen the lathe so these are 'off the top of my head' suggestions, hope you get a result soon. Regards Tony Ashgrove
