I think you may have just got a bad one, my blade tension can't be adjusted by any other means, but it works perfectly fine, so I see no reason why it might need to be changed.
Perhaps one defect accoutns for you both your complaints, a stray guide perhaps not holding the blade vertical, and as a result, shortening the correct route of 1140mm in length preventing you from tightening as the blade its literally cutting corners? Edited By Russ B on 05/11/2020 13:06:58 |

ahhhhhhhhhhhhhhh..................I think I might have unknowingly had the brushed version? it did a few good jobs albeit at a drastically reduced speed vs my 240v/110v gear but hammered my 4ah battery, which normally lasts a week or more of daily odd jobs M16-M20/pipe/flanges etc on the 1/2" impact gun. I sold it practially brand new for about what I paid for it (£29.99 without battery/charger)

Martin, I have the Aldi one (£149.99 delivered last year I think) - the blade tension is fine, I could play a tune on it and the weld is flat and smooth, I'd be taking it straight back before they have none left to exchange it with if I were you! (And hoping its not a crap batch!) Milwaukee do 10, 14, 18, 24 TPI and 10/14 and 14/18 TPI variable pitch. Not all of those are available in europe in the more economical packs of 3 or more blades, so it takes a bit of looking around on the net. I can't for the life of me find where I got mine from, I'll have to check the bag/box in the garage for clues. |
Thread: I'd like a simple plastic injection machine or designs |
03/11/2020 14:15:19 |
Jeff, As I suspected, very expensive to do properly! I already have polyurethane and silicone casting equipment as I made a valve head and cast a PU sealing face onto it for a small (by my standards) injection machine (typically pulverised or pellet fuel injection) I might contact the local supplier to see what other options might be available as the PU i have would be too soft although probably chemically compatible. I’m still going to gave a look at this DIY machine, i’m too curious..... |

Chris/Jeff, Chris, it's always good to have some companies to call up, thank you, putting injection moulding terminology and quieries into google is a waste of time, I was trying to find out how NBR parts are made the other day to see if I could make my own and it was like I was asking the meaning of life, every answer was totally different and none hit the mark! |

Jeff, Thanks for the input, regarding clamp force, I had planned on justing bolting the two halves together, as I don't mind making one, then waiting for it to cool, taking it apart and making another, I'm not really trying to brake any speed records, maybe half a dozen in an hours, and I'm happy. It sounds like I won't be getting the finest quality parts, but I will be testing and gather quite a lot of data and see what works best. I will keep in mind "hold up" time, obviosuly it's a 1 shot wonder, but I don't know how long I need to leave the material in the got barrel before I consider it to be thoroughtly melted and ready to go so given your comments, I'll test parts for strength having given them maybe 2, 4, 6, 8, 10 minutes heating up, see if a sweet spot appears??

It might be worth checking out, do you recall when/where it was?

Well I've drawn up some plans of my own as no one came up with anything! |

I've cut 60mm solid EN16 steel bar with mine, no trouble, and significantly quicker than my power hacksaw, smooth as silk. |

I got the £150 workzone one from Aldi, it came with an M42 bimetal blade, which has now lost a tooth after years of use. I was cutting up some 7m lengths of Dexion free hand and it snagged and chipped a tooth, no biggie. Ironically just less than an hour ago, I liberated a fixed jaw and screw type vice off a damaged Makita saw from work, looking at it, thinking this is a much better design! The one coming up at Lidl has the exact same screw type vice design with the quick release nut!!!!!! Edited By Russ B on 29/10/2020 13:15:35 |

29/10/2020 12:56:32 |
I'm looking to reproduce some plastic pipe connectors, I can very easily source standard Tee's/Y's etc but I really want an exact reproduction of what the machine should have and the parts are incredibly basic in shape. Does anyone have a simple DIY arbour press type plastic injection molding machine they'd consider selling? |
Thread: Manual for Harrison M250 or late Colchester Bantam |
20/10/2020 13:03:57 |
Not sure about the Raglans, the 280 looks identical in many ways to the Harrison M300, same bed casting, same saddle, same headstock casting but the two speed change levers are mounted on top of the Myford but are still basically the same inside the box. The apron and the screw cutting box are different but elsewhere the similarities seem never ending! It seems no one knows anything about their manufacturer but I’ve seen so few out in the wild I wonder if they ever produced them in any reasonable quantity. Someone must know something, I’d assumed they were made in nottingham but never seen any photos of the production, whereas there are many pics and history of the rest of the range. I’d be surprised if they weren’t made by Harrison. |

Thanks, i’ll take a look. The lathe came with a user manual and parts diagrams but I don’t recall seeing any maintenance info beyond oiling etc Edited By Russ B on 19/10/2020 19:40:40 |

Does anyone have a pdf manual they could share with me for the Colchester Bantam or Harrison M250, I just want to make sure I’ve adjusted the spindle bearings properly on my Myford 280 which looks like it’s cut from the same cloth as the above two machines. |
Thread: How do I disassemble Vickers dual metric/imperial dial? |
10/10/2020 10:15:33 |
Well, I got there in the end! After all the trouble I had with the crossfeed dial I decided to strip and clean the compound, which turned into a full strip and clean of the compound slide. Interestingly when I stripped the much smaller vickers dial, it was actually exactly the same internally, the graduated dials were just machined down to around 3/8th larger than the press fit hub as per martin’s photo above actually, you can see comparing his dials to mine, mine have much more meat on the dials! After some comparison between the two, I reached the same conclusion but for a different reason which is kind of important just in order to understand what went wrong. Basically the press fit steel hubs internal spigot had been machined or rubbed down, presumably damaged OR a replacement part intended for what looks like the later design that Martin has NOS of? So when the knurled wheel was tightened, rather than locking the steel hub/graduated dial to the shoulder on the shaft it was pushing it into the steel mid plate. After machining the mid plate down there was then a small interference with the gear carrying backplate that retains the driven wheel and mid plate, only very minor, a quick hone and everything was as good as new, almost. The locating peg that holds the driven half of the assembly in place is a bit damaged, and slotted more than it should be! The whole assembly has obviously seen some abuse. So all functional now, albeit without the imperial readout as I had to remove the damaged pinion gear. Edited By Russ B on 10/10/2020 10:17:16 |
Thread: Shopvac Recommendations (Hoover, Vacuum Cleaner, Dust/Chip Collection) |

I have the B&Q cheapo hoover, wet and dry etc, has lasted me 8-9 years of hard use, building works, wood work, swarf oil etc. great piece of kit, i’d go straight out and buy another if it died tomorrow. |
Thread: How do I disassemble Vickers dual metric/imperial dial? |
07/10/2020 22:07:44 |
So, my steel mid section is actually thicker than yours, exactly 3/16” in the centre. It’s obviously been rubbing this for some time as it’s worn down a thou around the edges. I’ve determined from careful measurement and sketches an interference between the steel mid plate and driver wheel of 0.1305mm or 5 thou, it’s right there on paper, double checked the dimensions and laid it out twice. No way around it, it just doesn’t work. If my mid steel plate was 4.5mm like yours, I’d have exactly 5 thou clearance..... sounds comfortable to me. I need to get some 4.5mm plate or find someone with a small surface grinder!! This where I got the idea maybe I was missing a shim on the shaft, to space the wheel off the steel plate slightly.

Those photos confirm no shim. Is the driver dials steel hub pressed flush with the graduated gear ring (the side against the table in your photo) Does anyone know where the little plastic gears can be sourced. Size wise i’m not sure how big mine is. I’d say they functional top slide one is about 1.1/2” maybe 1.3/4” and the troublesome cross slide is maybe 2.1/4 ish, from memory which just looking at post seems to make sense. The fixed steel mid section is thicker on yours with countersunk screws, mines just a plate with regular pz2 screws (not metric) |
07/10/2020 12:46:22 |
Yes the photos would still be very useful considering mine still doesn’t work on reassembly! As i’ve said i think the steel hub isn’t pressed all the way into the driver/dial. This steel hub locates against the face of the first step on the shaft and because the gear/dial is standing proud it’s locking against the middle fixed steel plate when there should be a very small clearance I had initially wondered if I was missing a shim, but given the close tolerances of everything, Vickers probably didn’t need to shim anything!
