Thanks for this. I fitted them on Monday. I did oil the shafts before assembling. I was back down there tonight and the oil was still in the lathe so I'm hoping it all went well!

That's exactly how I sorted it - thanks

Mart - thank you for the wood chisel tip. That and a bigger hammer sorted it!!

Thanks for this but not sure how it would work in this situation. My seal is fitted with the metal face in the recess. I don't think I could drill the seal without damaging the part it's mounted in

Thanks mart. Is it unusual for seals to get stuck like this?

I've got a colchester chipmaster and I'm attempting to change the 2 oil seals on the clutch shaft. They are two different sizes. The smaller of the two popped out with just a little effort. The second larger seal does not want to come out at all and i ended up really giving it a bit of a pounding (any more and i am definately going to damage the flange). My replacement seals are made of what looks like a hard outer plastic casing with a more pliable seal face with a garter spring. The original smaller seal has a metal casing with the seal with garter spring bonded to it. The smaller seal was fitted so the bottom of the metal casing was facing out of the flange but on the larger it seems to be fitted the other way round so I think the metal casing has been pressed into the flange. How can I get it out? The two things I've been thinking about are heat or getting someone to try and turn the casing so thin I can get it out?

Do you have a suitable motor for this project? 10HP would easily cope. Possibly just a little smaller?

Motor speed might be important? 2 or 4 pole motor? Two pole at 2800rpm might be the best?

Three phase with VFD or a brushless DC might be best for wide speed variation choices?

Add to this lot the huge fan required, to supply the combustion air, and you are nearly home. Automatic. ash pan, grate clearing, etc might be a high priority?

Might also need a chain saw to cut down the oak trees for the smoking chips. Saw can be electric, of course - better for the environment than using fossil fuels.

I think bearings are likely fairly low on your list of priorities.🙂

Yep the things you mention I already have got covered off from when I built my hog roast machine. I'm really interested in improving the bearing set up hence my question but thanks for your input

Brilliant thanks for the responses. Looks like I have plenty of options.

So I'm looking to make a rotisserie smoker. Not like a hog roast where the spit is passed through the animal but more like a carrousel where 4 trays rotate round. Basically a smaller version of the attached photo. It will be used at relatively low temp (max approx 180). As with all my builds its about recycling so I'm looking for 'good enough' engineering and the opportunity to make bits. So far it's a barrel for the cooking part and a cut down gas bottle for the fire box.

I'm considering the main bearing options. I've got some spare bearings so was thinking of making some housed bearings which I would bolt onto the outside of the barrel but I'm a bit worried about the temp. Would bushes fair better? If yes would aluminium do (I already have some).

The main shaft us going to be 19mm pipe and it will be rotating at about 3 rpm.

Thanks Colin ⁷

I've got a space heater which is good but of course you need to buy the fuel. I also put in a log burner which is great and I can scavenge most of the fuel but I find myself sitting in front of it drinking tea!!

Thanks everyone. ARC Euro seem to be a well respected supplier so I think I am just going to go with them. Although I may go for the 125mm Versatile with the swivel base rather than the 160mm SG iron

Thanks everyone. Yes it's a bridgeport. I checked on the Bridgeport user group and the 6 inch seems to be the standard. I know the ARC euro Vices are imported same as the vevor items but I was wondering if there was going to a difference in quality?

Appologies for another vice question. I'll try and keep it specific.

Is the ARC Versatile SG Iron Milling Vice worth the extra £130 when compared to the Accu Lock Vise (6 inch versions).

Thanks Colin

It's a bridgeport. Thanks for the advice

Thanks everyone. I've not got a wide choice of balls!!

So my mill is missing a few 'tightening levers' for locking the quill and the motor in place. They seem simple enough to make. Can you buy the small balls to go on the end? I was hoping for something around 20mm threaded to say m6. If anyone could point me in the right direction I would appreciate it. Cheers Colin

When I was digging out the star point the wires just all gave way and broke down. I'm actually looking forward to trying to repurpose the other motor. I did have a quick word with a motor rewind shop and it's going to be too expensive. If it all goes wrong I'll get one of those unit's that sort of hang off the leadscrew.

Super useful-thanks

It really is dead because I killed it trying to rewire it to delta!!

So the motor on my milling machine table feed is dead. I've got another motor but the fittings are different. I intend to make a plate which will interface between the mill and the motor. I presume the motor mount will be to a standard which I can reference to get the dimensions? Can anyone help point me in the right direction? Cheers
