Thread: What Did You Do Today 2019
23/03/2019 15:45:27

Spent some time trying to figure out how to re-arrange my stuff ( take 'trying 'as optimistic thinking ) ended up making an adaptor plate for my compound slide handle to allow me to use cordless drill as auto feed for tapers etc …
not designer chic but hey ! it works...

Didn't have any 8mm hex bar for the centre drive & wasn't going to cut down a piece of 12mm just for a 'make do' set up so used some 8mm screwed rod ,couple of washers, nuts & some thread lock... Bob's your auntie... summat like that.

I tend to use WD40 spray on the small tote bins that have my short bits of steel plus some light 32 grade oil for my slide ways on my lathe / mill

How about changing rpm mechanically... change pulley sizes... a quick search on Google brought up a quick ref. could work out a cheaper method...

Hi Brian

Get yourself a 'ZEUS' book; it has the charts for ISO fit BS 4500- 1969 for clearance, transition & interference fits, plus a lot of other useful information.

Hello Bob (Packmule).
To create a new line you can use simultaneously the Shift key and the Return Key.
If you use the Return key alone you insert also a new empty line.
If you want to create an empty line just do Shift+Return tywice.


Best regards
Dias Costa

Bob... Always had to do the same on this forum, raised the question with moderators last year but never really got to the bottom of it. Still have to use the same method as Dias above. never have any probs on any other forum.

Thread: Workshop insurance
18/03/2019 10:17:07

Over the past 6 years I have created an itemised inventory of tooling in my man cave plus photographs on my pc. I have a folder marked up 'Hobby receipts' precisely for insurance purposes' . I was burgled 5 year ago & the scrote made off with a compressor, mics, various tools, filter / regulator & a couple of my first models. Having the receipts on hand made my claim straightforward & I duly received replacement value. I now make sure that my inventory is updated as & when I add to tooling. Must disagree with comments re.NFU, as when I asked for cover quote from them a couple of years later once they knew I'd been burgled they didn't want to know!.

Thread: Workshop insurance
17/03/2019 16:37:19

I have asked my Ins.Co. about my converted 'hobby shop' & they have stated that as it is an attached 'garage' but not fitted with an internal access door it is classed as an outbuilding & would only be covered as such to the tune of £2500, but for an extra 'Premium plan' cover payment this increases to £5000,this, as many members will know that would not cover replacement value of Lathe or/& mill alone, never mind all the extra's in there, needless to say I paid the 'premium cover' rate.

I have enquired with WM & they quoted me, at time of asking, £70 per annum, value up to £10K, but that was a couple of years ago. I'm not sure how you would stand with your present insurer with extra cover from a 3rd party insurer, anyone is / has been in this scenario?.

Back when I taught apprentices the training centre machine section had one similar for lathe tool grinding but, re Bazyle's comment, ours was two sided, had guide grooves, machined edges, precision angle scale. It was a beast with a cast iron base, 3 ph. Just can't recall the maker, maybe look through Lathes.co.uk for picture.

Thread: Warco WM 290V LATHE
13/03/2019 17:16:42

I only have the WM250V-F myself & that is doing me just fine; but looking at the WM290V at Warcos web site, it's more upmarket model with ac inverter drive & 2 axis DRO, but pricey, would like one mesel' but out of my range. IIRC a member called Thor has an earlier 290V, drop him a pm.

Thread: Tangential tools ?
13/03/2019 11:38:20

I have a tangential tool for general use too, but also a selection of indexible tipped tools, more a case of nice to have than application. I tend to use the tangential for every day use on MS, brass, & an indexible tip for aluminium although the tangential does just as well. On the few engines I have made I use brazed carbide tipped on cast iron cylinders & flywheels so like others I use what's best for me at the time.
