Tyme lathes?

Postby Bo'sun » Mon Jan 02, 2017 2:31 pm

Good afternoon All,

I'm going to update my Tyme SL750 lathe with a Tyme Cub. Why you ask? Because it will give me a swivel headstock for larger bowl truning, an extra spindle speed, and twin bed bars for more consistant headstock to tailstock alignment. Plus, the accessories I already have will fit, especially those that screw onto the somewhat unique M20 x 2mm headstock thread.

Anyway, to the point. Now that Tyme are no more, apart from the famous auction sites, are their any other sources for spare parts?

Many thanks.

Another question if I may.

Does anyone know the overall length of the Tyme Cub (the 750mm between centres model)?

I've just realized that the motor is outboard of the headstock rather than inboard as on the SL750.

Many thanks.

Many thanks for that tusses,

The first link appeared to be metalworking lathes, and I'm awaiting a reply from the second.

In the meantime, I have yet another question:

Hopefully, I shall be picking up a second hand Tyme Cub this weekend. I've estimated that the overall length for the 750 B/C model to be about 1400mm. If it's too long to transport, how do I swivel the headstock? Do I need a spanner? If so, what type and size?

Many thanks.

Good evening All,

Collected a S/H Tyme Cub at the weekend via the famous auction site for £65. To my surprise it came with the the bowl turning bracket, along with a variety of accessories including the long two post tool rest. Quite a bargain I think! Some corrosion to the upper surfaces of the bed bars, but after flipping them over it looks as good as new.

Many thanks for your suggestions. Derek Pyatt is the only source I've found for Tyme lathe spares. However, it hasn't helped me find a curved bowl rest for the Tyme Cub.

Thanks again.

Good afternoon Teza22,

Sorry for the delay, just got back.

The belt you require is a 200J4 Poly-V. Just for interests sake, the Tyme part No. is 101140 and retailed for £3.74 in 1986 (happy days eh!)

Hope this helps

Most lathes need the spindle taking out to thread a new belt on. Quite how you do that will vary from machine to machine.

Hello Teza22,

Just to let you know I haven't forgot.

Had a quick butchers last night. It looks like the shaft will need drifting from left to right. I'll have a more detailed look this afternoon and be in touch.

So you drift the spindle from left to right? Do you mean hit it with a hammer?
Sorry new to all this turning stuff so don't know all the lingo.
Are the bearings gonna come out as well?
I've taken out the xirclips & the grub screw from the belt pulley wheels but nothing wants to budge.
I'm worried about breaking or damaging anything so if you can explain what I need to do that would be greatly appreciated.

I don't know anything about the specifics of Tyme lathes but you should never ever hit any part of a machine directly with a hammer unless you are determined to damage it.
A piece of wood between hammer and machine or use a rubber mallet. If it does not move as you expect, don't bash seven bells out of it, stop, think and see why it might be not moving first.
Talking of grub screws, it is not unusual to find one grub screw on top of another to lock it it in place.

Hi Giler,

See Teza22's comments above. I also echo what 9fingers says. A little release fluid or WD40 might help just in front of where the circlip goes, or a rub with some emery cloth to remove any rust that may have formed in the bore of the headstock.

Hi Giler,

As I said see Teza22's comments above.

I'll have closer look tomorrow, and try to give you some more detailed instructions. You'll definitely need a pair of internal circlip pliers, sufficient to remove a 47mm circlip, and a 3mm allen key for the grub screw in the 800 rpm Poly V pulley.



















Sorry about the jargon, but I'm not sure how else to explain it. Where are you, you never know, you might be just around the corner to me.

I really dont understand why members don't put their approximate location in their profiles for this very reason.

Hi Giler,

Had a closer look this morning, and this is what I suggest you try. I haven't tried it (belt still OK), but I see no reason why it shouldn't work.

1) Remove the large circlip from the RH side of the headstock. You'll need some largish internal circlip pliers with max 2.3mm dia pins.
2) Remove, or loosen by several millimetres, the "knurled cup" grub screw from the 800 rpm poly V pulley (3mm A/F Allen key).
3) To avoid damaging the internal race on the LH bearing (should the bearing not stay on the shaft), make a drift 14mm dia with a 9.5mm spigot around 10mm long on one end. Hardwood may work, although you might need something a little tougher.
4) Use the drift to gently tap the shaft from the left. The pulley block should stop when it touches the RH internal face of the headstock. Continue tapping until you have sufficient room to slip the belt from the LH end of the shaft.
5) Replace the belt.
6) Reverse the procedure to reassemble.
7) Re-position the pulley block and replace the grub screw. I'm assuming the shaft will have a corresponding detent for the grub screw to ensure alignment and provide drive. The motor and shaft pulleys will need to line up correctly to avoid unnecessary belt wear.

Notes:

I don't think the shaft will move right to left, because I think there's another circlip on the inboard side of the RH bearing.
Depending on what tolerances have been applied, the bearings may stay on the shaft, inside the headstock, or a combination of both.
The pulley block doesn't appear to have a keyway (strange!), but the shaft has either a 0.38mm (0.015") step or very slight taper (it measures differently each side of the pulley block). If it is a taper, it's in the right direction to allow the shaft to move left to right.

Most important! If it doesn't look like it's moving, don't force it.

Hope this helps. Sorry I can't be more specific. Let me know how you get on.
