    Little Adept lathe for my 5 year old

    That's contrary to what I've learned about clamping, whereby the clamping force is increased if there is a downward angle towards the part that is been clamp. If the tool clamp was parallel, there is a chance that it will only be clamping on the inner edge only and the tool could be spat out as...

    Little Adept lathe for my 5 year old

    Ok, i took your dimensions John, and drew it up in fusion to see what it would look like, (i forgot the screw adjuster), however i think what you say about the thinness is correct. It looks too feeble, especially as it will be only 1/16" supporting those cutting forces. Follow the link and...

    Little Adept lathe for my 5 year old

    Hi John, Thanks for the drawing, you drew that quicker than I could in Fusion 360 lol. The bed casting is solid one piece, no raising of headstock without major surgery. Unfortunately there just isn't enough there in the top slide to machine that down, maybe 1/16" then you have 1/8"-3/16 of...

    Little Adept lathe for my 5 year old

    One other thing I've been thinking about with reference to the shower motor is surface speeds, and pulley sizes for reduction. The following I've found as a guide for recommended cutting speeds, (SFPM). Mild steel 100 Tool steel 70 Cast iron 60 Aluminium 250 Brass 300+ I've found the formula...

    Yes it's quite small isn't it! Especially if the tool isnt allowed to overhang. 1/16" bottom, and the post itself can't be more than 1/2"-5/8" dia.

    Little Adept lathe for my 5 year old

    Hi John, Thanks for the pointers. I had worked out that the split clamps and holder should be bored as one item, and the scaled drawing as you suggest was just to see what size roughly it would work out as, there probably isn't very much material to the bottom of the tool if I'm honest. I've a...

    Its always interesting to see how people approach the job differently. Different work holding, or machining method, so would be interested to see a thread on it if your so inclined to post up your progress when you start. As for supplier, I cant really comment on the quality of casting...

    Little Adept lathe for my 5 year old

    Still not clear on how the toolpost clamped, I did some googling and came across a thread on another forum that yould commented on, and shown pics of your post. Seeing it off the post, inside the bore it all quickly became clear, and I think four of those would be a good starter set for him...

    Little Adept lathe for my 5 year old

    Hi John, Nice, so does the tool, clamp onto an increased dia toolpost? from the drawing i'm not sure how it connects for height adjustability. Essentially its half scale id need for the adept. as the tooling i'm using is 1/4". 12mm is near as dammit 1/2". Jon Edit scaled to 1.5times smaller...

    Little Adept lathe for my 5 year old

    The paper has done the trick though, no movement with my finger now on the far end of the tool Well using arm power alone to flick the chuck around, and the smallest of small cuts, I've got a finish that I think I'd be happy with, much less chatter, and a shiny finish, so tool isn't a problem...

    Little Adept lathe for my 5 year old

    Ok Norm, Here s a few pics, you can see where the tool has been and where it's making contact. Also the toolpost bolt, seems upright. Maybe a good wet and dry as you say and a bit of blue see where would need scraping if any. The camera struggled to focus on that last pic so I hope it's...

    Little Adept lathe for my 5 year old

    I need to get my ML4 put together and up and running, there seems to be quite a market for lathe tooling for these small lathes. I've seen another adept pop up on a fb group, needing jaws for a chuck, also on the same post, another person asking if anyone has a tailstock. I've probably got...

    Little Adept lathe for my 5 year old

    I've got a nice bit of plate glass, 10mm thick. But only small, 60x300mm. The corner edges are broken off which is why it's been replaced as it was for a vacuum system on one of the production lines at work. The chipped edges means it starts to loose vacuum. I was thinking to file the clamp...

    Little Adept lathe for my 5 year old

    Just sat with the lathe and talking Josh through what does what, and where not! To put your hands or fingers. I think I may have just figured why it wasn't cutting as good as I'd hoped. I had the topslide retracted, so there would have been movement there, also the tool clamp doesn't seem able...

    Little Adept lathe for my 5 year old

    Thanks John, Can you provide external dimensions, as I was going to make a countershaft but I can't see how that motor would screw/bolt to a plate. Also need to do some maths now on pulley reduction diameters. Regards Jon

    Little Adept lathe for my 5 year old

    Thanks John, So connect terminal C to the live from the plug, then connect either of the outlets (but not both) L1 or L2 to the live to motor, Then a neutral from the motor back to the plug, earthing the lathe and any countershaft setup I do. I take it that a no release switch could also be...

    Little Adept lathe for my 5 year old

    Hi, I was a bit sceptical about using it to be honest, and also for me, let alone Josh. Is hard to control a constant speed at the spindle. So I think some form of speed controller knob would be better for usability. I've brought the motor into work today to ask the advice of some of the...

    Little Adept lathe for my 5 year old

    Well after sat at the dining table working on the little lathe, messing around with the HSS tool, I was just about to set away on another cut to test what id done, when the magic smoke got out the foot pedal..........At first I thought it was a stone caught in the fish tank pump, then the...

    Little Adept lathe for my 5 year old

    Hi John, No I've not tried the speed control yet, although it is sat with the lathe. I only finished getting the lathe back together yesterday, before all hell broke loose with the boys and the cat. Then the afore mentioned 4 hour drive, which included two children feeling travel sick, an...

    Hello Dave, does myfordboy have a video on machining these castings, and even (dare I ask) does he still make/sell them? Regards Jon
