Gav,
In your OP, you mentioned waiting for a 'green wheel' - I guess you have some lathe tools with brazed on tips that you want to sharpen.
Others may slay me for blasphemy, but personally, I'd say junk them. You should be able to do most of your work with run of the mill square section...
Mag drill cutters are perfectly happy when only taking a partial cut, and will work fine here, but with one big IF:
The rigidity of the machine that you're using has to be sufficient, and the work has to be clamped down. A milling machine's the ideal. Having heard how much slop some of the...
For the amount you need (I'm guessing it's a 2" disc or so), you could probably make some from a piece of ally sheet about 1.5mm thisc with a 2mm drill...
:whistle:

Knoba,
Interesting table. I did a quick calc, based on HSS cutters with a peripheral cutting speed of 100 feet/minute (about right for HSS cutting low carbon steel). Your table is pretty much spot on.
Now - look at the magnetic drills on the market, take the Evolution ME3500 for instance...
Zardoz,
Really interesting book!
Would you mind if I posted this link on the homeshopmachinist forum? I'm sure others would enjoy reading it.
Thanks,
Ian
Sam,
That makes sense; the original used bright bar as rollers; are the knurled rollers on the production model ardened after knurling? I've found that a knurl pattern wears pretty quickly on mild steel, and soon feels smooth.
Sam,
Thanks for posting the photos, especially of the prototype; that's a clever piece of kit. I like how you've arranged for all 3 rollers to be driven, and to absorb the slack in the chain.
The mass produced version doesn't appear to have the "3 wheel drive" that the original did, I...
Not much use to you guys in the UK, but I thought I'd have a quick gloat. One of the (very few) advantages of living in Holland is that all houses have 35 amp 3 phase supplies.
I laid a length of cable to the workshop, had it hooked up several years ago - haven't looked back since, it's...
Thanks Woz,
I saw the ME7500 which comes with a 3MT, but at 24Kg, it's like lifting a sack of cement!
Looking at the exploded diagram of the ME5000:http://www.evolutionpowertools.co.uk/uk_parts_pdfs/me5000.pdf
it almost looks like I can machine up a replacement cutter arbour with an...
Anyone know of a mag drill that will take 2 morse taper tooling instead of the standard 19mm spigot? The Evolution ME3500 *looks* as if it should have a 2MT socket in the spindle, it has the space for it, but it doesn't seem to. Something around 1200W / 12Kg, that sort of size if possible...
For the price, those things are remarkably handy; I bought one, removed the 2 wooden strips and the clamping mechanism which left me with a foldable set of legs. I fixed my dovetailing jig directly to it. It's still foldable and compact, and hangs on the wall.
Maybe do the same for a small...
Brendan,
a 13mm drill should be run at about 350rpm in steel. Some kind of coolant or lubricant always helps - the drills will last longer, the machine will need less power and there's less chance of the drill grabbing and throwing the vice off the table (ask me how I know this...).
If...
Brendan,
The machine is rated to put a 13mm drillbit through steel. You could use a larger drillbit in softer materials such as aluminium.
Alternatively, to make larger holes in steel, use an HSS or carbide holesaw. The limiting factor is often the spindle speed; what's the slowest the...
Reminds me of the last time I worked under something. I was taking the pistons out of a tractor, a Case 1490. No axle stands needed there.
The head was off, I dropped the sump and took the big end bolts out of the first conrod. The cap was stuck. A gentle but highly skillful smack with a...
Bill,
Maybe this machine is a bit too big for the average home shop machinist, and it's 3 phase which cuts a lot of hobbyists out. Few professional machine shops run shapers anymore, so - luckily for me - the dealer couldn't get rid of it to anyone.
Oddly enough, he had a really tired...
To all those who have, or are getting a shaper - well done! Really enjoyable machines to use, dead cheap to run (they use large-sized lathe tools which you can grind freehand instead of milling cutters).
Great for hogging large amounts of metal off, also for cutting splines, internal &...
