I just had a look at Hafco\ Hare & Forbes, $1650.00 is a good price for a BF20L at this stage of the game. Doesn't look too bad, judging by the accessories may even be a genuine Optimum. Going by...

What would that hole be for ? Apart from rear mounting the stepper for the Y axis I can't recall any one drilling the column.

Top job there, looking really really neat & clean.

I just look at either my mill or bike and both of us are covered in oil & grease.

I'd replace the bearings, after 20 years they probably wont be in great condition, even if they are the sealed type they can dry out, get some moisture in them and get all funky, I'd even guess the...

About two years ago I replaced my spindle bearings with tapers and used some marine grease that I have, no problems at all, I've used the same grease when replace wheel bearings on a dual axle...

Yeah a touch probe will make life easier, not having a pendant with a wheel makes using an edge finder a little more difficult, for me anyways, than it was when the mill was manual. Actually I think...

A lot of us use the 570 on the Z axis with no probs. Have you checked out Hoss's website for his recommendations ?

Nothing much more than a length of square section timber with some sand paper fixed to it, drill a hole at one end bolt it to the table of the drill press, at the other end use a clamp to fix it to...

I'd stick with the drill press option. If you want to get fancy a jig to help you keep the wheel concentric to the axle could be the go.

Unless of course you really really want a lathe, then it...

Yeah I usually just go to my local bearing shop, CBC from memory, usually find you can get some good advice and you can be sure you're getting what you pay for. 9 times out of 10 if they don't have...

Yep Mach3 has backlash comp

You may also want to check out the mach3 forums as well, but........if you use an external motion controller, as opposed to...

I'd be checking that all your fixings are tight, if the bearing was shot you'd be able to feel that.

What type of bearing arrangement are you using and it's safe to assume you're using ballscrews...

The joys of living downunder. :rolleyes: Our Northern mates don't realise how good they have it...well access to parts.

Have you tried your local bearing shop ? Usually a good place to start.

Give these guys a shout Industrial bearings Sydney – Hooper Bearings Pty Ltd

If shelves are anything like mine you're looking at 475 odd pounds (plus shelving weight and whaetver else is on the shelf) bearing on 4 points approximately 2x2 inches. It's not so much the floor...

Nice work

I run the 6050's & 570's on my BF-20 and in the little time I've been running it haven't had any issues.

Hoss is The Man to listen to.

Seeing the fog would have been helpful, really can't make a comment about the output of the carb.

Mine is branded TopTech BF20, from what I can gather is a Chinese company, in a perfect world one would consider the German branded products to be of a slightly better finish. Without being able to...

G'day mate good to see you over here at the 'zone. I'm sure you'll get a wealth of help from the very fine gentlemen here.

Shame to here about your experience with Titan, I found my Lathe to be pretty good. I got my BF20 from Mcjing's in Sydney, and the fit and finish was quite good, had no issue with it. From pictures...

Machine cost & CNC conversion are quite minor compared to collecting the require tooling.

I bought my BF20 maybe 3-4 ish years ago and at that time it had the MT2 spindle, first mod I made was to...

I used that technique to make a flycutter out of 55mm 1045 steel.

First I used a boring tool to make a 16mm shaft, then put the shaft in a collet in the spindle and turned the final features....

Ray makes some great points, especially the cost and being less forgiving aspects.

If you can get a chance to compare the finish on a BF-20 versus a G0704 I think the BF-20 come off as slightly better finished. From the pics I've seen, and from my experience converting my BF-20,...

Yep I'll recommend Homman Designs as well. Great service and fast delivery.

You should have no problem with carbide, I've made a flycutter that uses a ceramic insert lathe tool, and that cuts fantastic.

You could always give Hare & Forbes a try. There is always mcjing,...

I'm running 570's on all 3 axis, and it's kind of scarey how fast these motors will move. And this is with a 150mm vertex vice on the table.

Big thanks to Hoss for his recommendations for the...
