Hi Bob.

The flywheels are laser cut from 3/4" plate. Dad was working outside sales for a laser outfit at the time so we had a couple sets of frames and flywheels cut. The problem is the cut edges are HARD!!! :eek: Broke up several carbide inserts before deciding the only option was to anneal them. Never got around to it and ended up without a shop for about 8 yrs. Forgot they were even out there until I saw your build. ::) Guess I'll have to get back on it someday.

Keep up the good work!

Cheers

Jeff
 
Hi Bob: Like a lot of people I have been following your progress on the Hit or Miss Me. You are doing very nice work.
Back on page 9 on of my build Hit or Miss Claire we discussed soldering the needle valve on these engines. Well no one chipped in with any information so I tried different things and decided to use a set screw to secure the needle. Pictures are on my site if you want to take a look.
One of these days we should have both of these engines going. Jack B
 
Jeff and Jack,

Thanks for stopping by and your support. :bow: :bow:

Things have been going nowhere for a couple of weeks now but..............I hope to do a little more this coming Friday. :eek: :eek:

Best Regards
Bob
 
Hang in there Bob....there's always a lull in the action on any project.

Dave
 
Dave and Bob,

Thanks for the support guys. :bow: :bow:

Seems like forever since I last posted and even now this is such a feeble effort. Non the less it is PROGRESS. :eek:

I spent some time pondering how best to lap the valves. In the end I decided that the old way was the best way but I needed a groove across the valve face for a screwdriver, the faces are too small for the old suction cup from a kids bow and arrow set trick, besides Dad "borrowed" all of mine and they're long gone :p

Here's what I came up with to make the groove/slot in the face.

After grooving the rest of the day was spent hand lapping and I reckon I'm about 45% done.

We are now on summer time and the central heating is catching its' breath with days 20-25 C.

Best Regards
Bob
 
Bob, Nice to see you back on the lathe again, cool toolpost grinder.
 
Progress is progress and anything counts.

Weather here is about the same only headed the other direction. Easing off of the 90-100 F to the 70-80 F. The shop will soon need some heat.

Jerry
 
Every little bit is a step ahead, Bob. Thanks for the update!
 
Good going Bob :)

I've never seen a reference to using a slot on the valve to use a screwdriver to lap it in; thanks for that tip.

:) Things sure are starting to heat up for us blokes toward the southern side of the globe now...

Kind regards, Arnold

Bob I don't post anything but replies to somebody from long, at least you do some little progress :)

go ahead mate (with your time of course)
 
Gavin, Jerry, Dean, Arnold and Ariz,

Thanks for stopping by and your support. :bow: :bow: :bow: :bow: :bow:

The spring has sprung and so has SWMDBO The paving discussed last winter has now been actioned. It's half finished and I'm completely finished. 2 full days with my Spanish mate Manual Labour and I almost forgot that I did some work on the engine last Friday. ::)

Also forgot to take the camera. :mad:

Anyway the valves are lapped and sealed to a test pressure of 1 blrf, (bung lung with red face). Valve springs have been sourced from my come in handy box and convinced to fit the valves. I started making the valve and spring keepers and next week camera permitting some pictures will be added.

Best Regards
Bob
 
Go Bob, Go Bob.... ;D

Looking forward to the pictures!

Dave
 
Dave,

Thanks for the Go Go mo bi le, ( remember them?) :bow:

Well slap me sideways I actually did a bit yesterday and even felt inspired :eek:

A couple of shots of the valves, springs, keepers and "E" clips instead of collets.

Next up was the carrier plate for the rocker arm and push rod.

Setup for drilling the mounting and carrying holes.

This was followed by profiling the plate. About 1/2 way through there was a thunderous bang and my lovely old 3/8" end mill became 2 potential boring bar cutters. I did have a somewhat heated and one sided discussion with the omnipotence upstairs, which made me feel better, however Gabriel explained it was his day off so just buy a new one next week. ;D Next time I wannabe an accountant.

Best Regards

You do have a way with words, Bob. Too bad about the old end mill, but it proves you were doing stuff! ;)

Dean
 
There's something satisfying about a blown cutter.....I remember the ones I blow up a whole lot more than the ones I just use. ;D :big:


And Yes I do remember Go Go Mobiles.... ;D

Keep at it.
