Shame that the drawings don't seem to be available any longer...

Harley-Davidson Shovelhead Miniature Model Motorcycle Gas Engine

I need to run a few tanks of gas through it first and then have a muck around with the needle jet and fine tune it so it rumbles more.
Really like this engine though.

Hi Folks
Back in the workshop for more decluttering and setting up the welding bench with a couple of vices. It is very hot here, though cooler in the workshop, but I certainly have not been enjoying the heat outside! Lovely to sit in but not to work in! So I get the bench fitted, and the vices, get rid of a load of scrap out of the luton, and everything suddenly starts to look better. A good tidy up is the best soul boost you can give yourself, well legally anyway!!

I've had a couple of set-backs in this project, and MOST of them are related to the M3 heat-set inserts that are SUPPOSED to hold things together.

Set-back #1 -
I recently installed the inserts into the upper and lower frame parts, I was trying to make the go roundy-roundy bits do exactly that.  As I was installing them I noticed that they were going in rather easily.  After I got all 2 dozen of them installed and started bolting things together, and MOST of the inserts failed when I tightened the bolts, I went looking for the culprit.  Turned out I was the guilty party.

The frame parts were the first one designed, before I found and fixed the X-Y dimensional accuracy problem.  Prior to fixing that problem my heat-set insert pockets would print under-sized, my solution was just to make them over-sized in the CAD model.  Soooo... after I fixed the X-Y problem, my over-sized heat-insert pockets ALL printed over-sized.

Set-back #2 -
I Could try gluing the inserts in, but MOST of them are going to be under enough stress from the rotating upper frame that I'm not comfortable doing that.  I don't think I've got enough filament left on the spool to re-print all the grey parts, and I couldn't find a manufacturer's label on the spool, so I just had to order some and hope for the best.  The colors DON'T match.  So I'm going to have to re-print most, if not ALL, of the visible grey parts.

Set-back #3 -
The grey filament that I was using was several years old, this made it stiff and brittle.  If the printer sat unused for several days the stresses caused by just unwinding it would eventually cause it to break.  I was working on the filler block that I need to install in the main drive gearmotors, before I clip the front corners off the gearmotor cases.  When I tried to print them out, I got a print failure.  Because the printer had been sitting unused for several days, the filament had snapped in the feed tube and I didn't catch it.  The extruder was running empty for several minutes before I caught the problem.  This running empty over-cooked the filament that was left in the extruder which caused a nozzle jam.  No problem, fixed that easily.  However, it also damaged the PTFE heat break liner, my LAST liner.  I ordered some new spare liners, and some more 0.4mm nozzles - just to be on the safe side.  They arrived, and rather than waste the remaining grey filament, I'm using it to print brackets to hold the OXA tool-holders for my Sherline lathe.  Those brackets, and the gearmotor case filler blocks, finished printing last night.  Now I'll pitch the remainder of the old roll of grey filament, switch to the new roll, and start re-printing the grey parts.

YouTuber 'Inheritance machining ' has one . He has used it for a few projects . It's one of those an impressive machines , that have been almost completely replaced by cnc.

Trying once again (and again failing to a small degree…) to create some order in a very overcrowded garage workshop, and as I pulled out numerous dusty things, I spotted this box hiding in the furthest, darkiest, dustiest corner of a shelf under the bench.
I bought this for my Bridgeport back in 2010, but then a year later I bought a Tormach CNC mill, so never actually got around to fixing it (it had 2 small broken bevel gears – I bought replacements, but never got around to fitting them) and of course never got to use it.
Bit of a rarity these days, and on this side of the Pond, but I expect that a few of you that have been around as long as I have will recognise it.

Hi Folks,

I am not dead (yet!) but haven't been posting in the engineering forums as what I have been recording has been restoring my house in Langtoft in preperation for its next tenant.  The house is finished at last, well nearly anyway but I will spare you the rest, apart from maybe getting the tree stump out, for which I have a cunning plan! I get a steel welding bench and add it to the workshop, and next week I will be fitting it and also adding a couple of vices and generally sorting the blacksmiths shop/welding area, and about time too! I feel another selling/decluttering session coming on!

Tracker mount lashed up ready for Monday storms.    Ade, lets see if I still have a tracker and panels on Tuesday....

I think it's only Scotland that got serious wind - it was all over the news here near Liverpool - but we were right on the edge of it, it's been "quite blustery", but nothing compared to some of the storms we had over winter.

As mentioned in my post above - I'm planning to move house next year; hopefully I'll have somewhere to put a solar tracker - or two... as well as my old Lister Start-o-Matic generator  :)

Well speak of the devil.... our power just went out.

Started up the old Indian Lister clone generator. Hand cranked to start. Two 24" flywheels.

Lights back, cooking dinner, router powered up, back online.

Soothing sound, putt, putt at 600 rpm in the distance instead of a 3600 rpm racket maker.

Nice! I have a real one sitting out in the back yard (firmly sheeted up at the moment, until it gets a new permanent home), unfortunately it's not exactly ready to make power just now... but then we very rarely suffer power outages here. I nearly sold it... but have now decided that, when I move house next year, I'll convert it to 3-phase & use it to power the mill & lathe.
