I'm just curious - what gets loaded on the dock leveller and what part's bent on the original? take it it's the manual/spring loaded/chain release type?
this was a good idea but I never did anything about it, been running it with the door open for almost a year...got the urge to play with the tig welder and made an extra part on the door to make room for the movement, going to get a magnet cupboard door thing to hold it shut
Too tight to start...I know I said replacement but they're a set of outside jaws, the inside ones are fine so will just be removing material from the new jaws....
yes, I mean to use it on the jaws, not the chuck
I only mention ‘stone’ because when I messaged the seller (Rotagrip, who were very helpful) he said ‘it’s usual to stone them down’
I do have a double sided 300/600 credit card size diamond I tried with but the edges are all worn away from using...
I just got some replacement jaws for my 3 jaw chuck...(never knew this) but the slot width is made slightly undersize to allow for wear etc and need to open them up about 3thou.
Slot is 220 thou wide so need something smaller than that
What are the options?
+1 for 'didn't know it existed', maybe obvious but I had to watch a Youtube vid to see what it actually does, I was imagining a magazine of cable ties :p
I have a Noco GB70...starts a Case 4210 every so often and an Isuzu pickup for a bit (until found out an electric window was drainig the battery), I got it in 2018 and (don't quote me on this but I'm pretty sure!) think I've only charged it 5 times, takes ages charging it with USB
as said, for 1 or 2 times a year a wired trailerboard (that you take back inside) or fixing whatever wire/connection has corroded before each trip is prob the best option
something you posted earlier this year.... https://www.mig-welding.co.uk/forum/threads/harrison-l5.131612/ says .032 when the spindle to powerfeed (or leadscrew) is 1:1
I measured how much the carriage moves with one turn of the powerfeed bar today and got 31-32 thou which matches the distance...
4tpi leadscrew, going by a photo from earlier there's 4 striations! per 100thou so 25 between them, edit - 3 per 100thou, so 33 thou betweenas I say tho it was using the powerfeed...
the gears being used were 20 and 60 drivers, 100 and 90 driven with gearbox set to x2, so would give 60 tpi IF...
I try to avoid cutting oil but I've tried oil when it's been happening before and didn't help
There's about 10thou backlash on the cross slide...can't rule out the cut being too light but it's just strange how it creates this pattern also have managed really light cuts with great finish but...
This seems to be an intermittent problem, these 'bands/ridges that I'm getting sometimes. This was at the slowest feed possible so it's not the tool directly leaving the marks like it would when cutting threads, carriage moving far too slow for that, bit hard to get a pic but u can feel the...
I don’t know exactly what it is tbh but it was bought about 20 years ago for making stub axles for carts/carriages, the person who did the machining and would know what it is isn’t here now
I don’t suppose there’s any way to tell or narrow it down?
It’s for a horse cart but let’s pretend it’s for a helicopter, or something else maybe
Seriously tho, if You can see the little groove in the test piece, the part up to the shoulder is 2 thou less than the side nearest the threads and the play in the bearings is noticeable
I bought this... https://www.amazon.co.uk/gp/product/B00C4RS3RY/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
after filling it you need to unscrew the nozzle so the oil is pushed out through the threads when you press the plug back in at the top, I've tried without loosening and no chance so...
cheers
starting with square because that's what I have...well, have been given!
I think the original in the pic is actually a collar attached, bit hard to tell because of the paint
