The Workshop Progress Thread (2017)

As well as working on the R&V engine I drew this out over Xmas/boxing day and have knocked up a few bits for it since then. Based on a general arrangement drawing that was in ME No4 of 1904 but made slightly smaller.

Again Maybe should be posted on Motorcycles General discussion but of interest to anyone.

With a bit of heaving, shoving, brute force and ignorance but surprisingly not any swearing, have just managed to shoehorn an oversize pallet into the last remaining bit of floor space in my workshop (until I build an extension......).

Strapped to the pallet is a Clarkson Mk II tool cutter grinder .

Finally got my lathe wired up and plugged in! Due to be serviced soon and off to the model engineers exhibition to buy some tooling on Sun 22nd!

I also commissioned a lathe today.

I picked up a bargain minter of a Super 7 back in October and took it to bits to get it home, as a friend gave me a plastic bush that he needed boring out yesterday, I thought it was time to put it back together .

This afternoon I put the toolslide back on, fitted my Dickson QCTP, refitted the motor, set the pulleys up parallel, wired the motor to the junction box, and away it went (well, after a bit of terminal swopping in the junction box).

Bush sorted .

Just added a 'proper' saddle clamp to replace the old ring spanner that was always in the way or not there.

Tonight I got round to assembling the crank case, crankshaft and cylinder assembly complete with pistons to check for tight spots.

Reassembled regulator and everything appeared to run free with end float. Lubricated pivots and set in motion. The clock would not sustain with 6 lb driving weight on a single cord, that is without the pulley. Deeply disappointing.

I am now trying to analyse the whole thing.

I have decided that I will put any further postings on the clock in the “John Wilding Regulator” thread.

I got the bearing supports finished off in the week

Then made a start on the cylinder and had all the bit sready to solder by Friday Evening.

Stuck it together with some silver solder on Saturday morning

Then machined my "casting"

Finally bashed out a couple of dozen studs and tried a few bits together

Just finished off my S10 OH & gave it a test run...

​p.s. still can't get the hang of putting in video  as a video clip even when embedding link as it says...?

It took me a week but I got the Rexon RDM500M mill drill back together again and installed the vise at about 2:30AM this morning. Second time in a row I put the heavy end somewheres I couldn't reach it easily. Had to make a little ramp to ease it down as the driveway was never put in and what was is 8" below the concrete of the garage. Made my new little crane pretty useless. Getting the head up on top of the column was a bit dodgy but luckily it wasn't that heavy. I'll be happy to get back into making chips ASAP - hopefully tomorrow night. I forgot some belts and we ended up using plumbing strap in two places but got lucky and lost little or no paint. Should have thrown something under the strap but didn't think it through.

Have ordered a new tool post for the ML7 as mine didn't have one. After hearing lots of good things went for a Dickson type from Lynham engineering. Once it arrives will measure up and order a tangential tool holder from eccentric....Now where's the best place to order material so I can start making Swarf!

Should add I'm in Hertford, England

In no particular order

As well as the Linishing Disc, I got the kit for a wobble broach from Hemingway. There's a few designs for one of these. Jock Millar did one in MEW back in November 2009 but that's a bit chunky for me. Mike Cox has a nice simple one but the Hemingway one designed by Mircea Halmagiu incorporates 3 ball bearings including a nice thrust bearing.

The tool is offset from the centre line by 1 degree, which I set up using my Wixey. The cutter has 2.5 degrees relief and I was able to use the Wixey again to tilt the head of my mill to the appropriate angle.

Seems to work very nicely, if somewhat unspectacular - it just feeds in!

That's a 5mm allen key snugly fitting in the socket.

I'm set up now to have a go at making some MiteeBite type fixings for my little CNC mill.

Cheers,

Might not look like it, but there is some traditional machine work in these suspension units. I still need to add the 1/8" rods through the middle of the springs etc. This is actually the inside as the nuts go on the outside.

Cheers JasonB, will help pass time during tonight's shift

On Tuesday I cut and pickled these four bits of 1/4"ish black bar for the crosshead guides on teh horizontal steam engine.

Did the machining on Wed & Friday evening and today finished them off by filing the curve to the stiffening webs and drawfiling the machining marks away. The extra work involved will milling the black bar down to size seems to have paid off as there does not seem to have been any unwanted movement.

Nice work Rod. I've been watching Randy Richard making this Hemingway kit on his Youtube Channel. It's on my list to do, not least as they seem to cost hundreds of coupons to buy a commercial one. Simple enough concept.

Did you buy the whole kit including materials - or just the drawings? I dunno how it works.

Murray

Hi Murray,

I bought the whole thing - didn't really need the lumps of 7/8 and 1" steel but the 3 bearings and the screws are in the kit as well. BAZ, who posts on here from time to time, put me onto it.

There is also a length of 8mm silver steel. I bored the the holder for the bits a nice snug fit and was very pleased with myself. Unfortunately, after hardening, the shank of the bits had swelled to 8.03mm so I had to put the holder back in a collet and bore it out again

Cheers,

Rod
