Great idea mate,
Working on the cylinder body and shaft glands at the moment. No photos yet, maybe tomorrow. I am making it so the piston shafts will operate when the drive wheels turn. Lubricator is actioned from a cylinder driven from the steam exhaust chamber sitting on top of the twin cylinders. This won't operate but it will be there as will the lubricator.
Thanks for your comments and suggestion
Regards
Keith

Hi,
No photos of the WIP today. Making up a lot of components for the main piston cylinders and steam actuator for the lubricator (also went Christmas shopping with Cathie this morning)
Beginning to think that this locomotive would be a lot easier to make out of steel than wood. Lots of small components that are fragile until assembled. But, I think that makes this build even more of a challenge. Broken parts can be made again !! Should definitely have photos of the cylinder and actuator tomorrow (finished Christmas shopping!!!).
Attached is a photo of drawing of what I am making - main steam cylinder, actuator and lubricator.
PS - My loco is double the sizes shown on the drawing.
Regards
Keith

Hi all,
Been working on the main drive steam cylinders. These are located underneath the chasis on the Lion at the front of the locomotive. There are cylinder covers and glands at the piston shaft end. These were pretty difficult to make. Initially tried to make as one piece and shape the gland. This looked very ordinary. I decided to machine up the components in the lathe and then made up the gland holding flange out of 6mm MDF. I then glued the 3 component parts together and clamped them up. Came up fairly well. I put gaskets in between the cylinder body and the steam exhaust chamber and also between this chamber and the top cover. Used 3mm MDF for the gaskets. The shaft above the RH side piston shaft is the actuator shaft for the locomotive lubricator. The drive arm goes from the buckle on this shaft to the lubricator (will be sitting behind the cylinders at the front of the loco). I am currently making the support struts that go from the cylinder cover glands to the motion plate.
Photos show the main cylinders, side view with the 5 degree angle so the connecting rod shaft won't foul the from wheels and a view of the cylinder cover plates at the front of the locomotive.
Regards
Keith

Cheers mate

Looking after Josh today, but managed to get out in the shed between plays and sleeps. Made up supports for the cylinder body and motion plate.
Also made up the turnbuckles for the piston shafts so we can connect to the conrod that will drive the main wheels. Dallas (Treecycle) has been very busy and turned up the blanks for my wheels. Thanks heaps mate.
Regards
Keith

Hi,
Back in the shed today. I worked on the main drive wheels (18 spokes) and trailing wheels (11 spokes). I drew up the wheel spokes with correct angle spacings for the differing spoke configurations. I photocopied these so the would all be the same for the 18 spoke and 11 spoke wheels and then glued them on the inner blanks. I then cut out the spokes using my band saw. The inner blanks (spoke section) and out rims are a press fit. I placed PVA glue around the inside of the outer rim and pressed in the inner spoked section. I then went around and placed extra glue at the contact point of each spoke. I then removed excess glue. I will allow it to dry overnight before doing any filing or sanding work on the spoked wheels. I reckon they will be pretty strong and with careful work the spokes won't break. Didn't break or crack any spokes in the bandsaw cutting process. Glad I did some practice a week or so ago to get technique correct.
Regards
Keith

It looks like your on a roll mate. (see told you never miss an opportunity)
But they really do look great Keith.
I think your right they should be more than strong enough.
Keep up the great work.
Cheers mate
Trev.
