Thread: universal pillar tool long arm castings
15/08/2021 20:58:18

Sorry but I thought that the idea behind GHTs Upt was the fact that it was for model makers. If you want bigger use a run of the mill drilling machine, it will also have a decent size column.

Thread: Silver solder? ....... or what?
15/08/2021 10:19:42

Robert, your father would not have used silicon bronze to oxy cast iron he would have used manganese bronze, very similar to look at but very different behaviour on cast iron.

Thread: Dividing this would have been an interesting exercise !!

Is it possibly a bahtinov mask

Thread: Belt lacing clips
14/08/2021 21:38:10

Thread: 16mm Indexable tool holders
10/08/2021 21:34:22

+1 for j b cutting tools and definitely Iscar or kennemetal tips.

Thread: Boat fittings...window frames.
10/08/2021 16:44:23

Have you tried using thick walled tube and machining a step in it, part off, anneal and form the shape as before. You then are able to insert the frame and have a frame trim on the outside.

Thread: 1.5 allchin lubricator
09/08/2021 22:40:35

Reeves list several lubricators

Thread: Sealant or gasket material
06/08/2021 22:35:16

Jason please don’t use diy silicone it’s full of acid, use automotive gasket silicone it’s chemistry is different no corrosive elements.

Thread: Knurling tool
06/08/2021 12:30:50

Made the Hemingway/Marco version during lockdown, what a revelation I thought my knurling were passable before but now their pretty to look at and repeatable which is useful as generally there’s more than one on most jobs. Nice kit to make.

Thread: Moving vice on mill table....
06/08/2021 12:25:11

If the mill is not complaining (noisy) when this happens I think I would go for hold down problems, but as somebody said previously are your cuts too ambitious and are the cutters sharp. Plus one for the paper but not thick.

Thread: Use Chequer (Tread) Plate as Roofing Sheet?
03/08/2021 17:29:03

DMB , Treadplate comes in several thicknesses.

03/08/2021 17:20:26

Sorry but don’t have a problem I can add up and take away as I am over three score years and ten!!

03/08/2021 12:55:26

Mark , My 10M is a late machine 1976!! so it is metric but still uses imp screws. The vert screw is 11/16 dia x 8 tpi. The dials are marked 3.2 mm per rev which proves the 8 tpi. Hope this is of help.

Thread: cylinder bore lapping
30/07/2021 18:16:29

Tug, Didn’t think it would be long before you spotted this one!!!

Thread: governor for steam engine
30/07/2021 18:14:34

I would imagine that that the 90 dog fitting would be fitted to the steam chest as it would make the governor rigidly fitted and the steam inlet from below as it already seems to have a pipe fitting attached to it. And possibly turn the top half of the governor round 180 dog to put the belt pulley more over the top of the engine making for an easier belt run.

Thread: Source of scale checker plate?
30/07/2021 18:01:54

Blackgates used to sell it in 3 sizes but it was a fair while ago.

Thread: Taig Backshaft Project
28/07/2021 09:31:07

Just wondering what you are doing to warrant 50 rpm? I spent my time on the bearings etc to get it to 9800rpm, fantastic for 1mm shafts!

Thread: Running needle roller bearings
28/07/2021 09:27:13

If it’s for a hot air engine where friction is your enemy would you be better to use ball races, much less contact area than needle rollers. And you can buy them with different clearances.

Thread: AA batteries
27/07/2021 13:56:47

I thought it was more that the battery boxes in stuff made in you know where are a bit scant on dims. American stuff that takes batts is ok, or mine is!!
