Looking at the photo of the angle irons, I can't understand what they are doing? Unless they are welded together, it doesn't look as if they are actually holding anything. I'm probably missing something obvious.
Regards, Steve

Hi Steve, Sorry for not explaining the set up, but I did write a much longer version the other day and my internet gave up before had added the photo and I lost all of the writing, I just didn't have the will to do all again. The two angle are welded together to make a X I was going to weld in some bracing fillets, but the job seemed rigid enough without them.

I haven't posted much lately, but that doesn't mean nothing has been done. I was asked if I could make some paddle wheel spiders for a member who is building a model of P.S. Waverley. Another member asked if I would machine the faces of parts he had fabricated to make his mill head swivel. 21.08.2018 by John The Pump, on Flickr For the train spotters this passed through the Pumphouse yesterday, calling in for a small repair. It only came to the Island last Wednesday evening and not many new about it including myself. When I arrived at the club yesterday a little late having stopped off for a blood test, most of the chaps present seemed to be huddled in the loco shed out of the rain. As soon as I walked in I realised what the interest was and was asked what my opinion was as to how to get the broken part of as small nipple out of the manifold. My answer was, load in a vehicle and take it to the Pumphouse for repair. So as tea was made we had an early lunch and then set off. 17.10.18 by John The Pump, on Flickr This engine was bought from Station Road as a runner needing some little bits of attention.it was run at the club last Saturday by the owner and one other and ran very well as we all saw from the video that the passenger made. there was a small steam leak from the union supplying the pressure gauge and it was when they tried to rectify this yesterday that the union failed, it rather looks like the brass had corroded. Not surprising when the small end of the union is 6BA 0.11022 and the hole through it a No.58 0.0420. The broken off bit came out very easily, My triangular scrapper pointed end screwed it out with no trouble. 17.10.18 by John The Pump, on Flickr It wasn't long before a new part was made and the Loco was reloaded into the vehicle and a happy member was on his way, the loco is scheduled to run this Saturday on a members day. I have managed to do a little more to my loco the cylinders are now bored and we are working on the cylinder cover at the moment. John.

Nice to see the thread back in action, John. As so often at the Pumphouse, there's always something turning up. I remember we also machined up some drivers for a Stirling single. And repaired a loo seat.

A little more progress on No.4 With the cylinders bored and lapped, the covers were the next job to be tackled. Wilf was turning the covers to fit the bores while I set up the the rotary table and clocked it with zero in line with the X axis. Then the first back cover was machined for the slidebar seat, the pocket for the gland packing and drilled and tapped for the gland studs. 19.10.2018 by John The Pump, on Flickr 19.10.2018 by John The Pump, on Flickr I decided to move the rotary table along the mill bed a little before doing the 2nd back cover as it was a little to close to the end. While the rotary was off I made a stepped bush which has a through hole tapped 8mm to fit in the centre hole from underneath, this will allow a center clamp down bolt to be used when necessary also better clamps were found. 19.10.2018 by John The Pump, on Flickr

I spent a couple of hours at the Midlands M.E. exhibition on the Sunday before going onto North Wales for a few days of narrow gauge railway fix. I bought a reset-able tail stock handwheel for my Myford Super 7 and on my return home i was slightly disappointed with the result, I did phone and ask if there was a part I had neglected to buy but there wasn't, 08.11.2018 by John The Pump, on Flickr So I set out to make the part myself and in the odd box under the bench I found a short billet of stainless steel just right for the job. The first thing to do was to remove the old part and take measurement the tread was 1.38" x 20 tpi. I made use of a bench micrometer an old gentleman gave to me on his second visit to the pumphouse, using thread wires to get the effective diameter of the thread. 08.11.2018 by John The Pump, on Flickr Having machined the part and cut the thread I came up with a novel way to support the tail stock while checking the thread fitted. 08.11.2018 by John The Pump, on Flickr Then it was onto the mill to drill and tap the oil hole and then engrave the reference mark. 08.11.2018 by John The Pump, on Flickr Then the final assemmbly. 08.11.2018 by John The Pump, on Flickr As Steve (Springcrocus) used to say on this Forum, thanks for looking in. John.

His progress can still be followed on his web site, although he does go into hibernation for the winter and do work on his model railway layout in the warm loft. John.

Regarding the re- settable tailstock dial, I purchased two of them from Nottingham Myford and they were supplied compete and ready to fit. A fellow club member purchased one earlier this year from the new Myford company and his also came minus the threaded piece. He contacted Myford and was told that is how they are supplied. Luckily he was able to make the missing bit at work.

Welcome to the site.

A little more progress with the loco, the cylinders and covers have been set up on the rotary table for drilling and tapping for the studs. 24.11.2018 by John The Pump, on Flickr The machine vice to the left of the rotary table has lots of dings and marks, as it was a free gift many years ago and was like that then, if should I mark it I won't be as upset as if it was pristine. The thing I like about this vice is that the front jaw is fixed and when referenced up as Y 0 and the left hand end of the jaw X 0 the job is all in the positive on the DRO. Although work on my loco is slow other jobs do happen in the Pumphouse. Last Wednesday Wilf modified some Tee clamp bolts for his lathe, they required new threads as they had been cut down, he held them by the shank and screw cut them 3/8" Whitworth and then parted the stub off and then finally cleaning the thread up with a die. It is a bit of a shame that I don't get round to taking photos of all the jobs, I should try harder with the Pumphouse open Tuesday and Wednesday evenings lots of different things turn up. John.

I got back into the workshop late this afternoon and carried on with the drilling and tapping of the cylinder ends and covers. It needed a slightly different clamping arrangement to hold the front covers in place. 25.11.2018 by John The Pump, on Flickr With the cover removed the holes were tapped. 25.11.2018 by John The Pump, on Flickr This just leaves the front of the other cylinder to be done. John.

Another interesting job came to the Pumphouse this afternoon, tonight we will try and free up the seized parts. hanging on the crane is the exhaust rocker arm with the centre pivot pin ( 2" diameter) seized solid as is the roller on the end of the arm. on the bench is the inlet cam follower and that roller seized. These parts are from a Ruston & Hornsby 9XHR Oil Engine 66Hp 27.11.2018 by John The Pump, on Flickr With the upside down chassis of my 7 1/4"G. Edward Thomas in the background give a good idea of size of the parts. John.
