Hi John,

I used a very similar felt on my lathe, been in use for over 12 months now, works great. To cut it use a sharp wood chisel works way better than a knife.

Hi Werner,

Coming together nicely! Great to see an update.

Hi Andre,

It was one of the guys in my club that sent the article that the EUREKA tool came about from!

the guy passed away some years ago so i cant supply any more info. I do remember the club night it was discussed at when he got confirmation that an article would be written

Cheers Kerrin

Hi Jason,

Yes i am aware that Ketan doesnt sell the SX4, just thought he may have info on the issue.

I reduce the speed to zero using the speed knob. Its been a couple of years since the board failed im pretty sure that i used to do it then as well but used to push the estop to change tooling, cant remember using it to just stop the mill

Like i said i only gad the mill a couple of years & hadnt done that many hours when it failed. Searching online

indicated that it was not an uncommon occurrence!

Mike,

Since having to fork out the thick end of $400 for a new board i havent used the estop! After all replacing boards cuts into other tool purchases!

Cheers Kerrin

Hi Guys,

I have an SX4, but this may also apply to the other models, have heard that it did happen to an SX3. I had my control board die. After a bunch on google searching it appears that using the stop button puts a pulse thru the board, which is ok for awhile, then it kills the board!

Some guys had managed to fix there boards & the same thing happened again. I ended up replacing my board, had to wait several week, at the time my mill wasn’t that old! Oh I also used the speed control knob to stop the mill but used to push the estop when changing tooling etc...estop if a panic arose!

There is a fix by putting a relay in, where & how is outside my ability’s!

Jason maybe Ketan may be a where of this & can offer advise?

cheers Kerrin

Hi Werner,

It looks like you & the others had a fun day!

The Tram looks to be running very well, you should be very pleased. Minor challenges are character building!

Cheers Kerrin

If you guys like these cans you are really going to like the ones that have recently arrived down under, they have a flexible metallic straw. You can get it into all sorts of places.......getting it out again is another story,

Cheers Kerrin

Hi Harry,

I measured up my existing tool holders, averaged them out, draw up in CAD & took the file to a water cut company, 2 days latter they rang to say the first one was done, would a care to come & pick it up & give it a try before they did the rest. I fitted great! No adjustment needed.

Cheers Kerrin

Hi Kaleb,

No problems at all with the setup. I'd have to flip him on his side to check but there may be a half link in the chain to get the spacing correct. I seem to remember spending a bit of time sorting out the distance between the sprockets. A friend worked for a supplier, which is were I got the chain & sprockets, so had the info required to sort out the distance. The springs are reasonably firm so probably not a lot of movement.

Re your other question on frames etc. Tobys frames are mild steel, as are the axel boxes & they ride face to the frames, horns are 12mm key steel from memory & only because its nice & square! Drilled a hole in the frames & put a squirt of oil in ....when I remember!

Just reading Perko7's post & version 2 of the coupling between the motor & angle grinder head is a 3/8 universal joint, I kept the socket end, drove out the pin on the spigot end, modified a 11 mm socket...use the 6 point one....I started out using a 12 point one & it was starting to show signs of wear...& pinned it back in place. Only reason I used 11 mm was I've got a bunch of hex that size. I milled the motor shaft to fit the 3/8 socket end & located a short length on the hex to the grinder head. Lots of km's & no issue!!

Cheers Kerrin

Hi Kaleb,

Sorry for the delay in replying work, life & the universe got in the way! If you have a look in my album I've upload some photos of how I mounted the motor & gearbox, hopefully they are helpful. Happy to answer any question.

Cheers Kerrin

Hi Kaleb,

I built a Toby Tram back 14 or 15 years ago. I got the construction article from the Australian Model Engineer. I changed a couple of thing, changed to 24 volts & 24 volt motor mounted vertically in the center of the axels. Coupled this to a 4” angle grinder head. The motor is 5000 rpm max, the grinder head has a 4 to 1 reduction, from memory! I then further reduced this 2:1 to the rear axel, with 1:1 to the front, chain drive grinder to axel, and axel to axel. Coupled it up this way so that when running forward the coupling chain tightens up & lifts to give more ground clearance for ground level running.

He’s run many happy kilometers! I can post some pictures of the motor mount etc if you are interested.

Cheers Kerrin

Hi Nige,

Here’s a link to my knurling tool. Simple to build, works great. The knurls, 4 pairs from China at $30 NZ delivered would be pretty hard to beat. The custom QCT holder on the other hand wasn’t cheep!

Cheers Kerrin

Hi Peter,

If you check out my photos there’s a couple of photos of my table. Takes about 10 seconds to get on & off, “& best of all no tools required!

Cheers Kerrin

Hi Michael,

Yes that's us!

Cheers Kerrin

Hi John,

I'm a member of the New Plymouth ME club. By your discription it's the one! Two off set circles so that you cross over, the bridge is just before you come into the station. I could give you map reference if you like, but the trees are such that you can't see the track!

Cheers Kerrin

PS forgot to mention it's a raised track if that help jog the memory, oh & the mountain isn't far away!

Hi Pete,

I built a sucker a while back, I used the fan out of a vacuum cleaner, no idea which as I nicked the fan off dad! I enclosed the fan and attempted to make an involute ( well I think it is) put an chimney on it so the smoke is directed up, not much fun breathing up coal smoke, espeacally if it's got sulphur in it! Like the idea of a speed control, have to go to Jaycar & get one.

Cheers Kerrin

Hi Michael, I just happen to have a Nigel Gresley in the loco shed, aka my dads workshop. I didn't build it so off the top of my head can't answer your question but can go early next week to have a look and let you know. Maybe in the mean time somebody else will answer the question Cheers Kerrin

Hi Neil, ok not that heavy! I had the "fun" of driving on a 5" ground track on a lite trolley, made the mistake of leaning the wrong way approaching a corner, had the 8 wheel trolley on the outer 4.... Provided the entertainment for the following driver! Declared then & there to build a multi gauge ground elevated trolley, just about there!

Cheers Kerrin

Hi David,

I built an electric Toby Tram about 12 years ago, he's an 0-4-0. Yep not as he should be but he's run many km's with very few issues. The guy that designed him used an air conditioning motor from a car running 12 volts. My version has a 24 volt X mobility scooter motor in him. The gear box was stuffed, I've mounted the motor vertically in the middle and fitted a 4" angle grinder head to take the drive below the "floor" with chain drive to 1 axel & then another to the other. The biggest issue was finding batteries to fit the available space! I went for marine ones, the added bonus is that they have handles on them which makes lifting them in & out easier. The motor does 5000 rpm unloaded the gear box has a 4 to 1 reduction with another 2 to 1 to the axel, I sized the wheels so flat out with a tail wind down hill he max's out at 12 km's per hour. With the 0-4-0 wheel arrangement you have to watch out for "bobbing" about, I spaced the wheels about 50mm from memory further apart than design so they are pretty much under the center of the batteries & have no issues. The only other suggestion I would have is buy the best controller you can afford, I've just up graded mine, get one with regen braking, save whoops if the kids are driving. Toby will quite happily pull 3 adults, the limit comes on up grades when he looses traction if you have to stop! As to trollies don't make them light! They run much better with some weight in them, also as big a wheels as you can, at the risk of being shot down 100 mm min! You only need about 1% of the weight of the trolley to move it.

Cheers Kerrin

Hi Dave,

I was fortunate enough to exchange letters with David way back in the mid 80's, at which time he was in his mid 80's and in hospital. If you have Micks lathe then I guess it's name plate will be Impetus, numbered 5? David had 5 sets of casting done, I know of 1 in the States, as to the others no idea, at the time I couldn't afford the £247 for the casting, plus freight, at the time it was probably a good buy! David's orginal (made in Malta if memory serves, & I think was left there), he made all but the head stock pattern, as it involved a complex core. The ones cast in the UK were made by a friend who was a great pattern maker by all accounts. The casting didn't include the drill press as David had decided to remove it from the design if memory serves.

Ive followed the Stepper Drive lathe series in M.E. & think it's a neat new generation of David's idea.

Hope you find this useful, if you do have this machine I'm jealous! Isaw it come up for sale & was very tempted, SWMBO was not impressed with the hints being dropped!

Cheers Kerrin
