If you are happy swapping belts to change speed, either swapping to a single phase motor or using a Static converter are cheaper options than a VFD + motor swap or rotary converter. The 3 phase motor on my Boxford shaper was 415V only & the star point is buried deep - as I had a single phase motor with the same frame size to hand, I swapped out the motor. A bit "grumblier" in operation than a 3 phase motor, but it shifts metal just fine. A Clarke PC20 static converter was purchased to run a sm...

I originally created the various drawing sets for both Model Engineer and RCM&E along with a 32 drawing originals for the proving group who tested my drawing skills to ensure I had not dropped a bollock somewhere, you would assume myself and Alex own the rights to the originals? I cant remember the terms but it was Alexs baby. I hosted the original plans for free I only feel it fair to let folk have access to them again especially in these mad Lockdown times. Im working from home on my own and ...

Magazines are mailed out in advance of general sale, and normally arrive around Monday or Tuesday before an on sale date on the following Friday. It is clear that the Royal Mail...

I dont understand.... on the one hand I thought that as of now, the minimum tax threshold for VAT/ excise/import duties was to be reduced from £15 to zero therefore VAT etc. is now payable on all purchases via online market places offshore vendors etc.... On the other hand, this link seems to imply the minimum tax threshold for offshore purchases is £135.00?? Or have I just misinterpreted? I am clearly in a post seasonal brain fog of too much food n booze so could someone that understands ...

The Perris came with original 1/4" ribbed (cross belt) belts - I seem to recall that there was similar on my Flexispeed but it came with no motor so dont know if it was original - I would assume driven just like the Perris with a cross shaft driven by motor on a hinged support so that weight tensions the drive belt - the spindle runs in cast iron (be very careful on tightening these as too easy to crack them) so not really designed for high speed + keep well oiled - you need the cross shaft to ...

Just to clarify in relation to Brian Ms comments re insurance, if used in line with the Health and safety at work act, and hence PSSR legislation then an air receiver on a compressor requires a suitable report of examination under a written scheme of examination once pressure x volume is greater than 250 bar litres (ie a receiver of 25 litre volume and rated for 10 bar. Hence hobby use most likely excluded. If it were a club application then risks to personnel are different and liability diff...
