|Thread: Potty Mill Engine Attempt|
third attempt at posting this. This site isn't really tablet friendly from what I can see. Hitting delete sometimes takes me back a page and deletes the post rather than deleting the text, but here we go again.
I am trying the Horizontal mill engine also by Stewart. Many thanks to him for making these drawings available. I wasn't happy with the result of my slide bars so decided to make them differently hoping that it will be easier for my first engine build.
Photo above shows my progress so far including the slide bars I wasn't happy with. Hopefully I will get some more time in the workshop this weekend but I have some shelves to finish first for storing off cuts.
Great start Daniel.
My first mill engine attempt is under way as well but after a hiccup I've decided to change the design a bit to make the first one a bit easier, well for me at least. What engine are you building?
|Thread: Telephone / Internet Scams|
I've been getting messages left on my mobile by a company called Lowells. UK debt collections mob. Net is full of complaints about them. They leave messages with a made up name, ref no and says they need to speak to you urgently, yeah right. I thought I had blocked all of their numbers but got a text yesterday with the same crap from them. Another number blocked now. If you get any calls from these people block their numbers and don't give them any info.
|Thread: Boxford AUD needing a new Motor|
3 phase with vfd would be the preferred choice
|Thread: Older/cheaper lathes|
My first metal lathe was a myford and I wasn't impressed by it. As others have said they do have a die hard following and can be expensive for what you get. I now have a Colchester bantam which I find to be a far more capable machine. Mine was around £1600 delivered and in good condition. I did rebuild the screwcutting gearbox which cost around £90 I think just because it was very noisy. Total cost still well inside what a myford could cost you.
|Thread: Horizontal engine|
Jason, did you ever publish drawings for that engine?
|Thread: My wife thinks I'm loosing it|
We will be in FW 1st week in April. No train this time but a trip up the mountain is planned. I hope you enjoy it Martin.
We've done the train trip a couple of times and it's fun. The only complaint is that you don't have a lot of time in Mallaig, about 2 hours I think if you travel back on the next return. But it's long enough to grab a snack and cuppa in the Tea Garden Café. No affiliation to it just happy customers.
|Thread: What Did You Do Today 2019|
Decided that I needed a more robust fly cutter so dug out a bit of round bar and got to work. Ended up with a decent looking fly cutter which fits into a 19mm collet. The cross bar is 25mm diameter and drilled to accept a 12mm Hss bar. Now I need to learn to grind the Hss bit correctly and get some test cuts done.
|Thread: Modern equivellent idea's please|
Is that an old Bill switchfuse isolator? If so be careful with it as it will probably have asbestos flash pads.
|Thread: Stepper Motor Controls|
Chris, what are you intending to do with the stepper motor? This will have an impact on what type of control you need.
|Thread: Aluminium black|
Managed to get a short time in the shop tonight and had another go. Cleaned the part down again and gave it a rub with scotchbright and cleaned again with isopropanol. Dropped several drops of Ali black into the spots with a small syringe and left for 4 to 5 minutes then washed down with water.
The results are far more promising.
|Thread: Stepper motor and surface finish|
Didn't see any marks on the cut edge on any of the machines I built using stepper motors. As John says when cutting material the motors will be stepping fast enough that it will be near continuous motion. There are various bits of hardware and software out there for control side. A lot of people go for Mach3 but personally I didn't get along with it. I did try Eding cnc and liked it but was part way through my next build which would have been using Acorn but decided to scrap the build and have a go at model engines instead.
|Thread: Aluminium black|
Thanks for the input guys. I will have another go later in the week when I get a chance to get back into the workshop. I think I will try a bit scotchbright pad on the dots and then fill with the Ali black and leave for 5 minutes and see what happens but I will test on a bit of scrap first. Maybe differing grades of Ali need longer for it to work properly.
|Thread: Single phase verses 3 phase motor|
Yes vfd and 3 phase motor all the way. Some wiring and a few buttons and switches and you can choose from fwd/rev. High/mid/low speed or fit a pot and vary the speed to your hearts content.
|Thread: Single to 3 phase invertor and smart meters|
One of the problems with smart metres is that they don't all talk to each other. We had one fitted last year then switched supplier and now have to still go read them and email the reading to our current supplier.
|Thread: Aluminium black|
Now that I have finished rebuilding my mill I decide to try it out making some aluminium dice. Two were milled at around 56mm square and I decided to get some aluminium black to colour the dots. So the surfaces were degreased cleaned and wiped down with isopropanol and let to dry. Applied the aluminium black with a small paint brush and made sure all of the dots were covered, waited a couple of minutes, bottle says wait one minute, then rinsed everything down. Finish results were very poor. Some parts black and others without any colour at all. The bottom of the dots seemed to be better where the liquid had pooled so should I have filled the dots completely and do one side at a time instead of trying to complete all sides at once? Is one or two minutes really long enough time? Any ideas?
|Thread: Warco Super Major Mill|
I have the GH Universal mill which isn't too much different from its big brother. The mill is generally ok but don't expect it to take any heavy cuts. I'm in the middle of rebuilding the gearbox and quill, on mine and was thinking about doing a few posts on it. Some things I did find which I'm not too impressed about though. Whoever built it decided that circlips make good spacers and the machining for the fit on the drive shaft bottom bearing is crap. The old bearing came out far too easily and the new one literally fell into place and ended up being held with bearing fit. Some of the moving gears have the edges bevelled so that they slide into mesh which definitely isn't one of my favourite's.
So if you remember that your buying a diy/hobby mill then they aren't too bad just don't expect Bridgeport quality.
|Thread: Centec question|
My first mill was a centec with the MK3 head and I made a new drawbar for that as well. I'm pretty sure it just lifted straight out. Try some gentle persuasion.
|Thread: Round indexable tips.|
I have a little fly cutter with round inserts. Seems to work ok if I go easy with it but when I have finished rebuilding my mill gearbox I plan on making a bigger fly cutter with Hss cutter. I gave a few plans for them so just need to pick one and go for it.
